Resonance Curve

Some might inference a very spherical world, but when you take "this view below" the world becomes very bumpy indeed. This was only possible by a revision in thinking and science of measure. Perspective was changed. The "biological genetic result" are lead by the mind, and not the other way around?:) Evolution of the brain structure makes me think this. Evolution of Emotive IQ, makes me think this.

This of course, in regards to biological thinking, runs in contradiction to everything that has been built up? What neurological pathways is built in thinking when your thinking "fires" neuronic pathways that never existed before?

While these pathways are already established, in our unthinking coordinated body movement these had been relegated to such a product of the species, after much travelling and exercising the mind's connection. Then w let it go, like we let many things go after repeatingly reliving the experience and assuming such idealizations. All thinking becomes biased then, yet we can meet the memory, and current daily incursions comparatively lived, by changing the way we see. By the way we meet situations. We had to open up our memory and track the evoluton of reaction.

That these migh tbe seen on anotherlevel, would have not been so far remved from the work being done on how gravity is thought about.



It's an ole way of thinking(GR perspective) and how measurement above, and at the earth, helps one see? That this process had been taken to very precise mesurements gravitationally considered?

Variable "constants" would also open the door to theories that used to be off limits, such as those which break the laws of conservation of energy. And it would be a boost to versions of string theory in which extra dimensions change the constants of nature at some places in space-time.

I mean when you take your thinking and transfer it to what happens within context of the gravitational field, then you soon learn the value of the photon within that environ.

The "spectrum" had been modified to a way of thinking, and is representative. But in order to do that, you had to move the thinking from GR to abstract valuations. You might not have seen this before, if you had not moved to a fifth dimensional understanding. "Spacetime wording" then becomes self explanatory, about it's every nature. "Spacetime" then becomes the "fabric of the cosmos."

Oscillatory Universe(21 Febuary 2006 Wiki)

The oscillatory universe is the hypothesis, attributable to Richard Tolman from 1934, that the universe undergoes an infinite series of oscillations, each beginning with a big bang and ending with a big crunch. After the big bang, the universe expands for a while before the gravitational attraction of matter causes it to collapse back in and undergo a bounce.

Drawing a Venn diagram: Entanglement Issues

Plectics, by Murray Gellman

It is appropriate that plectics refers to entanglement or the lack thereof, since entanglement is a key feature of the way complexity arises out of simplicity, making our subject worth studying.

The person above was kind enough to send information held in context of picture link for consideration, to help out with comprehension. I mean certain things hold us to consequences, that while I might have been thinking of Einsteins example of a pretty girl and a hot stove, this thinking did not pass my attention when one held the photon to certain enviromental influences as we gave these things thought processes. I context of "gravity as the square," is appropriate I think, about what combinations are realistic.



At the very heading of this post there is a link directly attached for consideration in context of all these possibilties. Some things come to mind in terms of Feynman's toy models, as strict interactive phase that we would like to keep track of. So what one might have done to say, hey, if we are given a possibility of scenarios about Entanglement issues, how shall we solve these interactive phases, as we try to build a multiphase integrative model held in context that perfect human being.

Entanglement applies to two or more particles even if one of them is used as input to the two slit experiment, it is not applicable to single particle experiments.

YOu know it is not that simple, but there are always grand designs on what we think something is nifty in society, as we progress our models of the future. As to how we will create the perfect models for apprehension about our universe, and how we interact with it.

Pictorial represenations can be very useful in presenting information or assisting reasoning. Venn diagram is an example. Venn diagrams are used to represent classes of objects, and they can also assist us in reasoning about the relations between these classes. They are named after the English mathematician John Venn (1834 - 1923), who was a fellow at Cambridge University.

While it is true that I am being fascinated by mathematical processes, and how they are used in our visionary quest for understanding, one would have to be a computer to remember all the interactive phases that could have manifested from a situation held in context of a "societal problem." One we might have encountered in our lifetimes.

It's statistical outcome that held to such micromanagement processes, would have been lost on all our minds, if we did not think some science process could have been touted with all these combinations.



Each time I am presented with this thinking, the elementals of the model for apprehension, it always seemed easier to me to just have a look and see what "buddhist principles" are telling us about how we have a hold of our world in all it's realisms. The choices we make, and how we are to conduct ourselves "becoming." Einstein used that term well I think.

So why such association and "combinations", that we have move the thinking here to what was gained in our emotive and abstract thinkings, as productive human beings? To see what a new foundational logic is being developed around our lives. Did we did not readily see the significance of the technologies involved. One had to dig a little deeper I think.

So here is a preview of what entanglement issue has been shown to help orientate views on this issue. Some diagram perhaps, to show the developing scenarios around such entanglement issues?



Quite early these indications about the possibilties of entangled states, raised all kinds of questions in my mind. Thinking of Hooft and others, about the issues of classical quantum processes, over top of these wide and incomprehensible statistical possibilties, seems held under the auspice of our reality model. That "square", given earthbound recognizitons, happily according to the basic pricniples, have so far held our views in gravitational model assumptions. IN essence, we have boxed the views on entanglement. As we have boxed Andrey Kravstov computerized model of the orignations of this universe in a supersymmetrical view of origination. What could have arisen from such situations. Probable outcomes?

Whether such a "quantum computer" can realistically be built with a value of L that is large enough to be of practical use is a topic of much debate. However, the mere possibility has led to an explosive renaissance of interest in the host of curious and classically counterintuitive properties associated with entangled states. Other phenomena that rely on nonlocal entanglement, such as quantum teleportation and various forms of quantum cryptography, have also been demonstrated in the laboratory

Quantum Experiments and the Foundations of Physics

For a more fundamental look at what I am looking for in guidance, follow this talk by Lubos. I most defintiely could be called a crackpot, but really, my heart and intentions are honourable and I will try to do justice to those things I am learning.

Dirac's Hidden Geometries

When one is doing mathematical work, there are essentially two different ways of thinking about the subject: the algebraic way, and the geometric way. With the algebraic way, one is all the time writing down equations and following rules of deduction, and interpreting these equations to get more equations. With the geometric way, one is thinking in terms of pictures; pictures which one imagines in space in some way, and one just tries to get a feeling for the relationships between the quantities occurring in those pictures. Now, a good mathematician has to be a master of both ways of those ways of thinking, but even so, he will have a preference for one or the other; I don't think he can avoid it. In my own case, my own preference is especially for the geometrical way.

For me the maths are not easy yet following experimental processes help me to direct my thinking. If we enage in philsophical talk then th eessence of this talk had to have a logic basis to it that is currently being expressed as far as I understood it. BUt even this logic take on new methods to expand and make room for the proceses for which we are engaging in talking about.

It is indeed a tuff struggle to remain current in thinking and stil embue our lives with the philosophies we hold in front of us?

The whole point is a comparison was made and reduced to philosophical idealizations, and was diverted from the math? There were consisent methods established that leads us to todays information. Is your philsophy based on what we now know?

Purity of thought around these issues, would have helped me to recognize that reducing these things to "philsophical debate" had to follow experimental processes, and that what I was trying to show, points towards the current work in scattering amplitudes(new models used?) to push perception.

How would our thinking change in how we percieve according to the new models we used for moving perception beyond what it currently houses?



Test of the Quantenteleportation over long distances in the duct system of Vienna Working group Quantity of experiment and the Foundations OF Physics Professor Anton Zeilinger

Quantum physics questions the classical physical conception of the world and also the everyday life understanding, which is based on our experiences, in principle. In addition, the experimental results lead to new future technologies, which a revolutionizing of communication and computer technologies, how we know them, promise.

In order to exhaust this technical innovation potential, the project "Quantenteleportation was brought over long distances" in a co-operation between WKA and the working group by Professor Anton Zeilinger into being. In this experiment photons in the duct system "are teleportiert" of Vienna, i.e. transferred, the characteristics of a photon to another, removed far. First results are to be expected in the late summer 2002.

Further research of Anton Zeilinger:Scientific Publications Prof. Anton Zeilinger

Quantum teleportation, step by step. Although the details of their experiments differ, both the NIST and Innsbruck teams have achieved deterministic teleportation of a quantum state between trapped ions:

First, an entangled state of ions A and B is generated, then the state to be teleported -- a coherent superposition of internal states -- is created in a third ion, P.

The third step is a joint measurement of P and A, with the result sent to the location of ion B, where it is used to transform the state of ion B (step 4).

The state created for P has then been teleported to B

(image and text credit: H J Kimble and S J van Enk Nature)

By taking advantage of quantum phenomena such as entanglement, teleportation and superposition, a quantum computer could, in principle, outperform a classical computer in certain computational tasks. Entanglement allows particles to have a much closer relationship than is possible in classical physics. For example, two photons can be entangled such that if one is horizontally polarized, the other is always vertically polarized, and vice versa, no matter how far apart they are. In quantum teleportation, complete information about the quantum state of a particle is instantaneously transferred by the sender, who is usually called Alice, to a receiver called Bob. Quantum superposition, meanwhile, allows a particle to be in two or more quantum states at the same time

The history contained in this post should direct any further perceptions I have, but you know, I still believe we will judge ourselves as to the constitutions with which we had choosen to exemplify in our continuing evolution of soul.

Wave Function and Summing over Histories

Dealing with a 5D World

A black hole is an object so massive that even light cannot escape from it. This requires the idea of a gravitational mass for a photon, which then allows the calculation of an escape energy for an object of that mass. When the escape energy is equal to the photon energy, the implication is that the object is a "black hole".

Paul Valletta:

Being that photons are the energy needed for observation by ‘observers’, what happens to a system when the limit of observation is at a minimum ie single photons?

Of course, I could be wrong?:)

"Which Way"? :)

Bohr's principle of complementarity predicts that in a welcher weg ("which-way") experiment, obtaining fully visible interference pattern should lead to the destruction of the path knowledge. Here I report a failure for this prediction in an optical interferometry experiment. Coherent laser light is passed through a dual pinhole and allowed to go through a converging lens, which forms well-resolved images of the respective pinholes, providing complete path knowledge.

Maybe comparative views can be held in context of the graviton as a force carrier as well, when thinking about your question above? There is a "certain influence" over top of your question?

Will this help us to move beyond the standard model?

Sometimes such a change in perception is necessary, to look to what is "contained" in the "wave function," yet there is something left over, that we had not analyzed yet?

How shall we describe this in context of the fifth force? Such a solution recognizes the advances made in GR with the encapsulation of Maxwell's equations and as well the leading indicators to such geometries, that we had witness in working to the Riemann sphere. BUt beyond this in compactive states of existance(quantum mechanics), how shall such views be encapsulated?

An Introduction to String Theory A Talk by Steuard Jensen, 11 Feb 2004

So how does all this come together into a physical theory? It turns out that the proper procedure is to construct every possible diagram allowed by the theory (for a given state of input and output particles and how they're moving) and add up the corresponding complex numbers. The result is essentially the "wave function" for that specific input-output state combination, and by squaring that number you can determine the probability that the given input will result in the given output. Doing that is how theorists at particle accelerators earn their keep.

Under these principals how shall a photon react to the enviroment in which it is moving? Moving, to encapsulate such views by moving to a fifth force is necessary.



While it is not always easy to see what is taking place, by perserverance I hope to one day understand the fullscope :)


Oskar Klein Collegiate Professorship Inaugural Lecture: "The World in Eleven Dimensions"by Michael Duff




Why?

Such a view of the photon held in context of the fifth force is the joining of gravity and light?

The least-action principle is an assertion about the nature of motion that provides an alternative approach to mechanics completely independent of Newton's laws. Not only does the least-action principle offer a means of formulating classical mechanics that is more flexible and powerful than Newtonian mechanics, [but also] variations on the least-action principle have proved useful in general relativity theory, quantum field theory, and particle physics. As a result, this principle lies at the core of much of contemporary theoretical physics.

Thomas A. Moore "Least-Action Principle" in Macmillan Encyclopedia of Physics, John Rigden, editor, Simon & Schuster Macmillan, 1996, Volume 2, page 840.

It is far better to understand the workings then just have wave a hand at it and said what a "crock of this or that"? What is worth while, that has been put into thinking here?

You just can't sweep it under the rug, and all is fine. Models, help in this regard, and if your comments were deleted becuase you didn't tow the party line, then should you have followed such orders and dismiss this model(your model?) which motivates to comprehension?

Some seem to think so, while they are held in the "same regardas arvix?" to which they themselves have handed out their criticisms and deletions. People who understand this statement, will know exactly what I mean. Those that don't. It wasn't meant for you :)

Laval Nozzle and the Blackhole

Often times model changes help perspective, where previously idealization will be contained. Moving beyond the experimental grasp for new ways in which to interpret, require a mode and offensive into producing new variations of ole thngs held in context? Ths is why such models like string that began in one mode in terms of quark confinement have now bloossomed into modes cocnerned with quantum gravity.



Discovering new dimensions at LHC

More dramatically still, the LHC could produce fundamental string relations of our familiar particles, such as higher-spin relatives of electrons or photons. There is also a possibility that, owing to the now much stronger gravitational interactions, microscopically tiny black holes could be produced with striking signals.

Once idealization and understanding developed in quark Confinement, it is understood the shift to the metric and the idealization of that measure became a property I found in the way we now deal with the perceptions containing dimensional significance? Strng Theory, that had graduade from the model apprehensions early on, here to a more fundamental pursuate of how we see in those extra dimensions, compact as they may be?

Acoustic Metric (29 Dec 2005 Wiki)

In mathematical physics, a metric (mathematics) describes the arrangement of relative distances within a surface or volume, usually measured by signals passing through the region – essentially describing the intrinsic geometry of the region. An acoustic metric will describe the signal-carrying properties characteristic of a given particulate medium in acoustics, or in fluid dynamics. Other descriptive names such as sonic metric are also sometimes used, interchangeably.

Since "acoustic" behaviour is intuitively familiar from everyday experience, many complex "acoustic" effects can be confidently described without recourse to advanced mathematics. The rest of this article contrasts the "everyday" properties of an acoustic metric with the more intensely studied and better-documented "gravitational" behaviour of general relativity

On the Universality of the Hawking Effectby William G. Unruh and Ralf Schutzhold

Addressing the question of whether the Hawking effect depends on degrees of freedom at ultra-high (e.g., Planckian) energies/momenta, we propose three rather general conditions on these degrees of freedom under which the Hawking effect is reproduced to lowest order. As a generalization of Corley’s results, we present a rather general model based on non-linear dispersion relations satisfying these conditions together with a derivation of the Hawking effect for that model. However, we also demonstrate counter-examples, which do not appear to be unphysical or artificial, displaying strong deviations from Hawking’s result. Therefore, whether real black holes emit Hawking radiation remains an open question and could give non-trivial information about Planckian physics.

It is important that when thinking about this universality that the derivations of such thinking is understood by me so I ahve to lay it out in a sequence that suports the end part of this post so that it is brought togher in a nice way. I bold mark thos epoints that help greatly in my understanding.

Acoustic_theory(28 Dec 2005 Wiki)

Acoustic theory is the field relating to mathematical description of sound waves. It is derived from fluid dynamics. See acoustics for the engineering approach.

The propagation of sound waves in air can be modeled by an equation of motion (conservation of momentum) and an equation of continuity (conservation of mass). With some simplifications, in particular constant density, they can be given as follows:


where is the acoustic pressure and is the acoustic fluid velocity vector, is the vector of spatial coordinates x,y,z, t is the time, ρ0 is the static density of air and c is the speed of sound in air.

Fluid Dynamics (28 Dec 2005 Wiki)

Fluid dynamics offers a mathematical structure, which underlies these practical discipines, that embraces empirical and semi-empirical laws, derived from flow measurement, used to solve practical problems. The solution of a fluid dynamics problem typically involves calculating for various properties of the fluid, such as velocity, pressure, density, and temperature, as functions of space and time

So these ideas in terms of analogies help to push forarwd understanding where we might have been limited in our views before. I know, they certainly help me.

"Analogue Gravity"
by Carlos Barceló and Stefano Liberati and Matt Visser

Abstract

Analogue models of (and for) gravity have a long and distinguished history dating back to the earliest years of general relativity. In this review article we will discuss the history, aims, results, and future prospects for the various analogue models. We start the discussion by presenting a particularly simple example of an analogue model, before exploring the rich history and complex tapestry of models discussed in the literature. The last decade in particular has seen a remarkable and sustained development of analogue gravity ideas, leading to some hundreds of published articles, a workshop, two books, and this review article. Future prospects for the analogue gravity programme also look promising, both on the experimental front (where technology is rapidly advancing) and on the theoretical front (where variants of analogue models can be used as a springboard for radical attacks on the problem of quantum gravity).

and here......

Parentani showed that the effects of the fluctuations of the metric (due to the in-going flux of energy at the horizon) on the out-going radiation led to a description of Hawking radiation similar to that obtained with analogue models. It would be interesting to develop the equivalent formalism for quantum analogue models and to investigate the different emerging approximate regimes.

I am always interested in how science might take these analogies in concert with how we understand blackhole horizon abilites. To exemplify the understanding of where "this place of virtual reality might issue from such a ground state" might be, in terms of what might flow one way, and what will flow in another, as photon pairs do from around the blackhole.

How far can this be taken as we look to understand Hawking radiation? How would such constrictions pave the way for sound emitted and held in context of Hawking Radiation, flowing through a pipe? We've had our lessons from Cosmic Variance on this, but would it have ever been taken this far?

Well, I still like to think about the gravitational comparisons here, so I would be very happy to have found some geometrical propensities towards how the horizon would have given us a good picture of what "first principle" might be as we look at the nature of hawking radiation, and how the standard model is featured from that horizon. So of course I am thinking deeply about all the things I have been learning.

I hope one day a comprehensive picture forms so that I can finally understand what is going on?

Further "Analogy" sought by me to help my perspective.

Bubble World and Geometrodynamics

Tiny Bubbles

Making Sense of the Nonsensical

From this experiment it is apparent that interference is destroyed by a "which-way" marker and that it can be restored through erasure of the marker, accomplished by making the appropriate measurement on the entangled partner photon p.

In this set up, the "which-way" measurement does not alter the momentum or position of the photons to cause destruction of the interference pattern. We can think of the loss of interference as being due only to the fact that the photons are entangled and that the presence of the quarter wave plates changes this entanglement. The interference pattern can be brought back through the erasure measurement because of the entanglement of the photons, and the way that the presence of the quarter wave plates and polarizer changes the entanglement.

It is very obvious I need some time to digest and listen carefully here. Of course I draw from Wiki quite regularly and I hate to think such efforts to destroy a concerted effort by those whose hearts are pure, for leading others into the correct methods, would not resort ot the efforts and likes of those Lubos has brought to our attention.

ON the note below taken from Lubos update, it is without thinking that I might have lured others into the state of complacency without fully understanding, and hence my part in this effort less than kind? So I'll draw back for a bit here and try and digest what I learnt and see if I can get it together.

Lubos Motl:

Note added later: let me mention that Kastner has submitted another paper criticizing Afshar's conclusions. In my opinion both Unruh as well as Kastner replace Afshar's experiment by a completely different experiment that does not capture the main flaw of Afshar's reasoning. The main flaw is that Afshar does not realize that for a tiny grid, only a very tiny percentage of photons is used to observe the wave-like properties of light; these are essentially the photons for which the which-way information is completely lost. Because most photons go through the lens without any interactions and interference, Afshar is not allowed to say that he observes the wave-like phenomena with visibility close to one. In fact, it is close to zero if a consistent set of photons is used to define both V and K.

Here is the paper >Kastner talks too in regards to the content of Afshar experiment.

Why the Afshar Experiment Does Not Refute ComplementarityR. E. Kastner

ABSTRACT. A modified version of Young’s experiment by Shahriar Afshar demonstrates that, prior to what appears to be a “which-way” measurement, an interference pattern exists. Afshar has claimed that this result constitutes a violation of the Principle of Complementarity. This paper discusses the implications of this experiment and considers how Cramer’s Transactional Interpretation easily accomodates the result. It is also shown that the Afshar experiment is analogous in key respects to a spin one-half particle prepared as “spin up along x”, subjected to a nondestructive confirmation of that preparation, and post-selected in a specific state of spin along z. The terminology “which-way” or “which-slit” is critiqued; it is argued that this usage by both Afshar and his critics is misleading and has contributed to confusion surrounding the interpretation of the experiment. Nevertheless, it is concluded that Bohr would have had no more problem accounting for the Afshar result than he would in accounting for the aforementioned pre- and
post-selection spin experiment, in which the particle’s preparation state is
confirmed by a nondestructive measurement prior to post-selection. In addition,
some new inferences about the interpretation of delayed choice experiments are
drawn from the analysis.

1. Introduction.The Young two-slit experiment is a famous illustration of wave-particle duality: a quantum particle emitted toward a screen with two small slits will produce an interference pattern on a detecting screen downstream from the slits. On the other hand, as has been repeatedly demonstrated, if one tries to obtain “which-way” or “which slit” information, the downstream interference

Presence and Entanglement

The equivalence principle(29 DEcember 2005 Wiki)

The accuracy of the gamma-ray measurements was typically 1%. The blueshift of a falling photon can be found by assuming it has an equivalent mass based on its frequency E = hf (where h is Planck's constant) along with E = mc2, a result of special relativity. Such simple derivations ignore the fact that in general relativity the experiment compares clock rates, rather than than energies. In other words, the "higher energy" of the photon after it falls can be equivalently ascribed to the slower running of clocks deeper in the gravitational potential well. To fully validate general relativity, it is important to also show that the rate of arrival of the photons is greater than the rate at which they are emitted

From a layman perspective, I am seeing that the nature of the gravitational field in a circumstance where such "strengths and weaknesses" would have been viable property to our way of seeing?

Lensing by showing us, that such avenues would have found the valution of the photon travelling the quickest route?

So, by changing the face of what we had always agreed upon( encapsulating Gr perspective bulit upon Maxwells creations and the geometries), as the way of energy and matter relation, such presence, would have then said, as a force carrier, that in these two cases, I will always be the way you would interpret my being in gravitational context?? You assume the model

So "always" in the "presence" of a gravitational field?

Fifth force(29 Dec 2005 Wiki)

A few physicists think that Einstein's theory of gravity will have to be modified, not at small scales, but at large distances, or, equivalently, small accelerations. They point out that dark matter, dark energy and even the Pioneer anomaly are unexplained by the Standard Model of particle physics and suggest that some modification of gravity, possibly arising from Modified Newtonian Dynamics or the holographic principle. This is fundamentally different from conventional ideas of a fifth force, as it grows stronger relative to gravity at longer distances. Most physicists, however, think that dark matter and dark energy are not ad hoc, but are supported by a large number of complementary observations and described by a very simple model.

Now, I am having a bit of a problem with the idea of "high energy" being "redshifted" because of the nature of the blackholes gravitational force? IN this case such a presence wouldhave by nature and strength of curvatures would have forced high enegy states to immediately curve backwards. If such blueshigfting is free to penetrate the fastest routes then such signs woudl have gave indication, yet the immediate horizon vicinity, plays havoc on these ideas?

The only way one could ascertain such a state of redshifting, is if "high energy" was evident in proximaty of the blackhole?

Would this be true or false?

Entanglement

Hypercharge (29 Dec 2005 Wiki)

In particle physics, the hypercharge (represented by Y) is the sum of the baryon number B and the flavor charges: strangeness S, charm C, bottomness and topness T, although the last one can be omitted given the extremely short life of the top quark (it decays to other quarks before strong-interacting with other quarks).

Plectics, by Murray Gellman

It is appropriate that plectics refers to entanglement or the lack thereof, since entanglement is a key feature of the way complexity arises out of simplicity, making our subject worth studying.

So by simlifying these ideas of entanglement, we find a model building from the orientation supplied by Murray Gellman, where expeirmentatin and hisortical pursuate have created a legitamate question about what Penrose might ask of a New quantum world view?




Secondly, entanglement issues were progressive, and historically this helps clear up the issues of spooky?


While dissident took us fastidiously to Hooft, I could also interject with Penrose?

But in doing so, such progressions from "simplifed states of plectics" would have taken us through a whole host of idealization in terms's of "dimensional significance," had we adopted Hooft's holographical vision?

If by Hooft's very beginnings, we had thought deeply about the progresions he had taken us too, then how would such developements have looked, if we were the prisoners, and the light behind us, pointed to the shadows on thew wall?

Acoustic Hawking Radiation

What did we learn from studying acoustic black holes? by Renaud Parentani

The study of acoustic black holes has been undertaken to provide new insights about the role of high frequencies in black hole evaporation. Because of the infinite gravitational redshift from the event horizon, Hawking quanta emerge from configurations which possessed ultra high (trans-Planckian) frequencies. Therefore Hawking radiation cannot be derived within the framework of a low energy effective theory; and in all derivations there are some assumptions concerning Planck scale physics. The analogy with condensed matter physics was thus introduced to see if the asymptotic properties of the Hawking phonons emitted by an acoustic black hole, namely stationarity and thermality, are sensitive to the high frequency physics which stems from the granular character of matter and which is governed by a non-linear dispersion relation. In 1995 Unruh showed that they are not sensitive in this respect, in spite of the fact that phonon propagation near the (acoustic) horizon drastically differs from that of photons. In 2000 the same analogy was used to establish the robustness of the spectrum of primordial density fluctuations in inflationary models. This analogy is currently stimulating research for experimenting Hawking radiation. Finally it could also be a useful guide for going beyond the semi-classical description of black hole evaporation.

I am held to a state of profound thinking when I thnk about Einstein in a dream I had. Where his satisfaction was raised, as a surpize, as I listen to the very sound of ice in a glass jug as I slowly turned it? From it, a certain recognition by Einstein held him in amazement as this sound seem to satisfy what he was so long search for in his answers. Yes it is a dream, but this set the stage from what I had been doing previous as I was thinking about the Webber bars and the way research was moving along this avenue to detect grvaiational waves. Movements to the giant Ligo inteferometers, to help us in our pursuate.

I know it is not always easy to understand the thinking here as it is piecemealed, while my minds works to weave a cohesive picture here. So, my apologies.

There is a special class of fluids that are called superfluids. Superfluids have the property that they can flow through narrow channels without viscosity. However, more fundamental than the absence of dissipation is the behavior of superfluids under rotation. In contrast to the example of a glass of water above, the rotation in superfluids is always inhomogeneous (figure). The fluid circulates around quantized vortex lines. The vortex lines are shown as yellow in the figure, and the circulating flow around them is indicated by arrows. There is no vorticity outside of the lines because the velocity near each line is larger than further away. (In mathematical terms curl v = 0, where v(r) is the velocity field.)

Early on the very idea of measuring discrete functions in relation to how we might percieve quark and gluonic natures which arose from the gold ion collisions, raises the very idea of how we may look at the analogies sought to help shape perspective from the horizon, to what is emitted? A Virtual Photon released in pair production at the horizon can become?

While I had come to recognize the differences in thermodynamic principals held in context of the blackhole, the very idea of He⁴raises some interesting scenario's in relation to sound values, while "extreme curvature" had been lead too as a singularity in the blackhole?? This singuarity thought to besimlar to the hawking no bondary proposal would not sit well with how the very nature of the blackhole actually becomes the superfluid that we hav come to recognize in the collider perspectives. This changes things somewhat. How fortunate is it in relation to how we see the supersymmetry that coudl arise inthe action fo symmetry break that signs could be lea dto the nature of the phton release and stretched under the aupsice of theis grvaiutional field?

Overlap of "quantum" and "classical" behaviour

Explanations of Hawking radiation around a black hole often use a description of quantum-mechanical pair production effects occurring on a curved spacetime background. Although this paradigm does not obviously lend itself to a "classical" reinterpretation, research on the black hole membrane paradigm has revealed some overlap between "classical" and "quantum" descriptions.

Plato:

What conditions would have allowed such a scene to be developed in supersymmetrical view, that I had wondered, could such a perfect fluid be the example needed? What blackholes hole would allow such a view to be carried down to this level in gold ion collisions, that we might see the results of string theory, as a useful analogy in the discernation of what can now be brought forward for inspection.

So having recognized the two phases of superfluids that ha dbeen created how woud such analogies move th emind to coisder this other nature of of a helium whose viscosity woud have allowed the sound to travel under the same aupsice held in context of the photon whose naure would havebeen rvealled in redshifting? Would suchj a thing held in context of blue shifting be cancelled out in quark/gluonic phases. that the analogy no longer suits our purpose? While sound i analogy in helium may have revealled the very nature of the superfluid designs we woudl like to see in comparsion to how thephotons are looked at with such short distances?

The laws of black-hole physics, written in this membrane paradigm, are completely equivalent to the corresponding laws of the curved-spacetime paradigm – as long as one restricts attention to the hole's exterior. Consequently, the two paradigms give precisely the same predictions for the outcomes of all experiments or observations that anyone might make outside a black hole …"

What is a Phonon/Photon?

Phonon:

A particle of sound. The energy E of a phonon is given by the Einstein relation, E = hf. Here f is the frequency of the sound and h is Planck's constant. The momentum p of a photon is given by the de Broglie relation, p = h/λ. Here λ is the wavelength of the sound

Photon:

A particle of light. The energy E of a photon is given by the Einstein relation, E = hf. Here f is the frequency of the light and h is Planck's constant. The momentum p of a photon is given by the de Broglie relation, p = h/λ. Here λ is the wavelength of the light.

As you look at the picture above, the very depths to which vision might have been imparted in recognition of this supefluid, what value would be assign something held in the context of the wave nature to have seen it described as a granulization and then thought of in terms of the langangrian perspective as cosmic strings which cross this universe? Make sure you click on the picutre.

Granularity of the Fluid?

Taken from the horizon, how would this fluid look if held in context of William Unruh's previously thought "continous nature" or as a discretium release of Hawking like phonons? It may be "by analogy" help physicists with respect to the nature of gravitational blackholes?

The Single Photon Experiment at Rowan University is a Success!

Einstein/Bohr Debate

"Not often in life has a man given me so much happiness by his mere presence as you have done," Einstein wrote to Bohr. "I have learned much from you, mainly from your sensitive approach to scientific problems."

John G. Cramer

This column is about experimental tests of the various interpretations of quantum mechanics. The question at issue is whether we can perform experiments that can show whether there is an "observer-created reality" as suggested by the Copenhagen Interpretation, or a peacock’s tail of rapidly branching alternate universes, as suggested by the Many-Worlds Interpretation, or forward-backward in time handshakes, as suggested by the Transactional Interpretation? Until recently, I would have said that this was an impossible task, but a new experiment has changed my view, and I now believe that the Copenhagen and Many-Worlds Interpretations (at least as they are usually presented) have been falsified by experiment.

The Single Photon Experiment at Rowan University is a Success!

Entanglement applies to two or more particles even if one of them is used as input to the two slit experiment, it is not applicable to single particle experiments.

Afshars experiment is conducted in such a manner that it is the setup of the experiment coupled with the conservation of momentum that allows us to know exactly which slit the photon has gone through.

Whilst knowing which way the photon has gone we also manage to show the absense of interference with both slits open via intererence minima.

Measurement without “measurement”: Experimental violation of Complementarity and its aftermath

Bohr’s Principle of Complementarity of wave and particle aspects of quantum systems has been a cornerstone of quantum mechanics since its inception. Einstein, Schrödinger and deBroglie vehemently disagreed with Bohr for decades, but were unable to point out the error in Bohr’s arguments. I will report three recent experiments in which Complementarity fails, and argue that the results call for an upgrade of the Quantum Measurement theory. Finally, I will introduce the novel concept of Contextual Null Measurement (CNM) and discuss some of its surprising applications. Web-page: users.rowan.edu/~afshar/ Preprint (published in Proc. SPIE 5866, 229-244, 2005): http://www.irims.org/quant-ph/030503/

Violation of the principle of complementarity, and its implications
Shahriar S. Afshar

Bohr's principle of complementarity predicts that in a welcher weg ("which-way") experiment, obtaining fully visible interference pattern should lead to the destruction of the path knowledge. Here I report a failure for this prediction in an optical interferometry experiment. Coherent laser light is passed through a dual pinhole and allowed to go through a converging lens, which forms well-resolved images of the respective pinholes, providing complete path knowledge. A series of thin wires are then placed at previously measured positions corresponding to the dark fringes of the interference pattern upstream of the lens. No reduction in the resolution and total radiant flux of either image is found in direct disagreement with the predictions of the principle of complementarity. In this paper, a critique of the current measurement theory is offered, and a novel nonperturbative technique for ensemble properties is introduced. Also, another version of this experiment without an imaging lens is suggested, and some of the implications of the violation of complementarity for another suggested experiment to investigate the nature of the photon and its "empty wave" is briefly discussed.

Has Speed of Light changed Recently?

You have to remember I am not as well educated as the rest of the leaque connected at Peter Woit's site. But how could one think anything less, then what perception can contribute, as less then what the educated mind might have thought of? If it did not have the scope enlisted by others in consideration cosmology might have expressed, then we might have reduced the value of reducitonism role in how we perceive the beginning of the cosmos?

So what Does Peter Woit say here? I am glad that the support(choir:) moved to Peter's cause for truth and enlightenment, is clarifying itself, instead of the ole rants that we had been witnessed too, in the past.

Understanding the clear disticnctions make's it much easier now, instead of what opportunities might have been past by? Of course I understood that he is quite happy with the life given, makes it all the more reason that the value of opinion will have direction(not hidden causes). Contributions by the the opinions generated, held to a educative process that we all would like to be part of.

Peter Woit:

In general, what I really care about and am willing to invest time in trying to carefully understand, are new physical ideas that explain something about particle theory, or new mathematical ideas that might somehow be useful in better understanding particle theory.

Strings /M theory moved to cosmological thinking because of where it had been?

Life, the cosmos and everything:

Lee Smolin stressed that it is only justifiable if one has a theory that independently predicts the existence of these universes, and that such a theory, to be scientific, must be falsifiable. He argued that most of the universes should have properties like our own and that this need not be equivalent to requiring the existence of observers.

Smolin's own approach invoked a form of natural selection. He argued that the formation of black holes might generate new universes in which the constants are slightly mutated. In this way, after many generations, the parameter distribution will peak around those values for which black-hole formation is maximized. This proposal involves very speculative physics, since we have no understanding of how the baby universes are born. However, it has the virtue of being testable since one can calculate how many black holes would form if the parameters were different.

So what are Lee Smolin's thoughts today, and one can see where the interactions might have, raised a claerer perception of what falsifiable is meant in context of today's reasonings. Has this changed from 2003?

Lee Smolin:

My impression, if I can say so, is that many cosmologists undervalue the positive successes of CNS. It EXPLAINS otherwise mysterious features of our universe such as the setting of the parameters to make carbon and oxygen abundent-not because of life but because of their role in cooling GMC’s. It also EXPLAINS the hierarchy problem and the scale of the weak interactions-because these can also be understood to be tuned to extremize black hole production. Further, it EXPLAINS two otherwise improbable features of glaxies: why the IMF for star formation is power law and why disk galaxies maintain a steady rate of massive star formation.

So while we are engaged in the thinking of what can be measured from the big bang till now( Sean Carroll has given us a positon to operate from), but having the Poor man's collider introspective, helps us to consider how we may see the developement of particle interaction, as Pierre Auger experiments have reminded us?

Since the COBE discovery, many ground and balloon-based experiments have shown the ripples peak at the degree scale. What CMB experimentalists do is take a power spectrum of the temperature maps, much as you would if you wanted to measure background noise. The angular wavenumber, called a multipole l, of the power spectrum is related to the inverse of the angular scale (l=100 is approximately 1 degree). Recent experiments, noteably the Boomerang and Maxima experiments, have show that the power spectrum exhibits a sharp peak of exactly the right form to be the ringing or acoustic phenomena long awaited by cosmologists:

Then how would we see such changes and views that might of held the mind to variances in the landscape, as hills and valleys, portrayed in our cosmo? Perception between the Earth and the Sun. What shall we say to these values in other places of the cosmo? Will we see the impression of the spacetime fabric much differently then we do with the fabric as we see it now? Some might not like this analogy, but it is useful, as all toys models are useful?

Had we forgotten Wayne Hu so early here, not to have thought before we let this all slip from our fingers, as some superfluid and how we got there, Whose previous existance we had not speculated(what about Dirac), yet we understand the push to the singularity do we not?

"How do you actually make a collapsing universe bounce back? No one ever had a good idea about that,” Albrecht said. “What these guys realized was that if they got their wish for an ekpyrotic universe, then they could have the universe bounce back."

Such gravitational collapse sets the stage for what was initiated from, yet, we would not entertain cyclical models, that would instigate geometrical propensities along side of physics procedures?

So what do we mean when I say that we have pushed the minds eye ever deeper into the world of the Gluonic phases, which we would like so much to validated from such "traversed paths" that such limitations might have then been projected into the cosmo for a better perspective of time? Langangrain valuations alongside of the cosmic string? Which view is better?



When I started to look at the idea of these xtra dimensions, and how these would be manifesting and the experimental attempts at defining such, I recognized Aldeberger with eotvos contributions here, that a few might have understood and seen?

Together now such a perspective might have formed now around perspectve glazes that we might now wonder indeed why such a path taken by Aldeberger might now have been seen in such fine measures?

The Shape of the UNiverse in Omega Values

Having walked through the curvature parameters, in the Friedmann equations while understanding the nature of the universe, I thought would have been very important from the geometrical valuations, that I have been trying to understand. That it might arise in a terminology called quantum geometry, seems a very hard thing to comprehend, yet thinking about CFT measure on the horizon(Bekenstein Bound) is telling us something about the space of the blackhole?

So people have these new ideas about quantum grvaity and some might have choosen monte carlo methods for examination in the regards of quantum gravity perceptive.

Plato:

Now some of you know that early on in this blog John Baez's view about the soccer ball was most appealing one for consideration, but indeed, the sphere as the closet example could all of a sudden become the ideas for triangulations never crossed my mind. Nor that Max Tegmark would tell us, about the nature of these things.

JUst as one might have asked Max Tegmark what the shape of the universe was, he might of quickly discounted John Baez's soccer ball? Yet little did we know, that such a push by Magueijo might have had some influences? How would you measure such inflationary models?


Plato said:

When I looked at Glast, it seemed a fine way in which to incorporate one more end of the "spectrum" to how we see the cosmo? That we had defined it over this range of possibilties? How could we move further from consideration then, and I fall short in how the probabilties of how we might percieve graviton exchange of information in the bulk could reveal more of that spectrum? A resonance curve?

Variable "constants" would also open the door to theories that used to be off limits, such as those which break the laws of conservation of energy. And it would be a boost to versions of string theory in which extra dimensions change the constants of nature at some places in space-time.

One of the ways that has intrigued my inquiring mind, is the way in which I could see how xtra-dimensions might have been allocated to the views of photon interaction? We know the ways in which calorimetric design helps us see how fine the views are encased in the way Onion people work?

I had recognized quite early as I was getting research material together of Smolin's support of Magueijo, had something to do with the way in which he was seeing VSL approaches to indicators of time valuations?

Again, this is quite hard to conclusive drawn understanding, in that such roads lead too, would have instantly said that (speed of light in a vacuum)C never changes? How many good teachers would have chastize their students, to have this held in contrast to todays way we do things when looking at Magueijo?

Magueijo started reading Einstein when he was 11, but he wanted to comprehend the theory using mathematics rather than words. So he read a book by Max Born, which explains relativity in the language of mathematics. He quotes Galileo as having said, "The book of nature is written in the language of mathematics."

Let's look at what is being said from a fifth dimensional perspective, and tell me why this will not change the way we see? Why model comprehension has not sparked this foundational change in the way we look at the cosmos and the spacetrime fabric?

Second of Five Lagrangian Equilibrium Points

The more I thought about it, the more it made sense that one image we're getting, is quite different(lensing) from the image that is behind the brane? The idea of brane collision from steinhardt and turok perspective, created this space bewteen the branes, while the image behind this(the other image) is receding?

I am not sure exactly.

Dark matter in the high-redshift cluster CL 0152-1357. Gravitational lensing analysis with the Advanced Camera for Surveys (ACS) reveals the complicated dark matter distribution (purple) in unprecedented detail when the Universe was at half its present age. The yellowish galaxies are the visible cluster member galaxies forming a filamentary structure, possibly in the process of merging.
(Jee et al. 2005, Astrophysical Journal)

Not many can see in this abstract way, or have considered how a photon might have travelled? Sure they have understood satellites and the travel through space, but have they consider this in context of CSL lensing? Sean put up a link yesterday that had me seeing how such a travel over distance might have had some photonic strange journies in context of such lensings.



The second of five Lagrangian equilbrium points, approximately 1.5 million kilometers beyond Earth, where the gravitational forces of Earth and Sun balance to keep a satellite at a nearly fixed position relative to Earth.

This picture below really set the final stage for me. Thus simplification has been mounted in how we see such tubes formed within the greater context of the universe and here we have a way of seeing that is new? It helps one to view universe travel and paves the way for roads through such space?

Is it so hard to visualize? Is it so hard not to consider how one should make there way through such space?


Weak Lensing Distorts Universe?

IN order to extend the link to the information supplied in previous article presented by Sean Carroll, Fraser Cain here links us to the following conversation.

Feynman's Path Integrals

While this following comment might seem inappropriate to the content of this post, I place it because of what I see in determination of the langangian methods used to help us see how gravitatonal equilibrium points, speak to how such travels would have been initiated in sum over paths used as Feynman's distributes the actions according to set model held i a cosmological sense I am looking at the the picture above here and the path ways shown.

Tony Smith:


As to the time of Feynman soving the QED problem, in 1941 (according to Mehra’s Feynman biography The Beat of a Different Drum (Oxford 1994)) Feynman had the inspiration from Dirac’s paper of using the Lagrangian method, which led to Feynman’s 1942 Ph.D. thesis. As to that thesis, Mehra says “… Feynman mentioned that “the problem of the form that relativistic quantum mechanics, and the Dirac equation, take from this point of view, remains unsolved. …”. So, Feynman’s Shelter Island relativistic QED solution was developed after his 1942 Ph.D. thesis.

I had been looking for this relationship and how Feynman’s toys models came into being? Can this be the beginning as you relate?

Decoherence

How to understand this quantum-to-classical transition linking two incompatible descriptions of reality is still a matter of debate among the various interpretations of quantum theory. In any case, one can probe the borderline between the classical and the quantum realm by performing interference experiments with particles of increasing complexity.

Of course I am cocnerned about the determinations of the paticle natures seen in a particular light. These constituent s are part an dparcel of a much larger view from increase entrophy( I always get these things a**backwards), and cooling temperatures?

Decoherence is relevant (or is claimed to be relevant) to a variety of questions ranging from the measurement problem to the arrow of time, and in particular to the question of whether and how the ‘classical world’ may emerge from quantum mechanics. This entry mainly deals with the role of decoherence in relation to the main problems and approaches in the foundations of quantum mechanics.

Of course I am paying attention and listening. :)Of course I want to find my way back to the classical world from where probabilistic valuations reigned. I was acting as a "gathering point" in my quest for a "philosophical design" (not to be confused with ID?). :) Okay, I understand this is not acceptable.

The difference between quantum and classical behaviour is exemplified by the famous “double-slit experiment”, in which photons are fired at a barrier containing two slits, and then allowed to fall on a screen opposite the barrier. Classical particles would pass through (at most) one slit at a time, but photons can pass through both simultaneously. The two waves associated with the photon passing through the two different slits fall in and out of phase with each other at different points on the screen — the phase of these waves being related to the total distance the photon travels from source to screen — so they interfere either constructively or destructively, producing a pattern of light and dark bands.

What motivated such cosmlogical design, as a crunching inevitable to have found the limitations of the energy having found itself turning back? So we do not see this right now and we speculate. this did ont take away from the isolated examples of unfoldment as a cyclcical process between energy and matter did it??

Oh for heaven's sake, where will my ramblings take me next? :)

Lubos Motl:

I would not promote overly technical lecture notes, especially not about things covered in many books. But the interpretation of quantum mechanics in general and decoherence in particular - a subject that belongs both to physics as well as advanced philosophy - is usually not given a sufficient amount of space in the textbooks

Those are strong words [shut up and calculate] for a layman to consider, when he is groping to trying to find his way.

Lecture 23 was pointed out by Lubos Motl in his article for consideration. More was considered from the list contained here.

If such energies were to be amongst the recognition of the quantum world, had we really been that separated from cosmological recognition of what constitued that beginning? Am I suppose to dismiss Weinberg in his first three minutes, for what might have been recognized in the first three seconds?? Remeber I am in the fifth dimension, where temeprature and entropic findings would have found a furthe rvalue to the discussion of what went this way and what that way. The entangling process is very profound.

So in looking back, we do not know where such a thing could begin? I think I understand that from what , although, if such proceses were recognized in the cyclcial nature of the cosmos why would we not entertain the rejuvenation of geometrical propensities to models inherent already in the universe? See the universe as a much "larger process" much different then the scope through which we might have treated each galaxy in it's rotations? Everett? Hmmm....

To map the "invisible" Universe of dark matter and gas expelled during the birth of galaxies: a large-aperture telescope for imaging and spectroscopy of optical and ultraviolet light.

To measure the motions of the hottest and coldest gas around black holes: a radio interferometer in space.

To see the birth of the first black holes and their effect on the formation of galaxies, and to probe the behavior of matter in extreme environments: a very large aperture arc-second X-ray imaging telescope.

To determine the nature and origin of the most energetic particles in the Universe today: a mission to track them through their collisions with the Earth.

I have been troubled indeed by the "orbital mapping" I speculated to the cosmological design, seen as "events" in that cosmo. By such happen stance, such relations seem to spark some wonder about the arrangement, to the fundamental library of that same orbital design. I made this mistake before, and I need to correct it now.

Slow down! "Antimatter?" "Pure energy?" What is this, Star Trek?

But you can see evidence for antimatter in this early bubble chamber photo. The magnetic field in this chamber makes negative particles curl left and positive particles curl right. Many electron-positron pairs appear as if from nowhere, but are in fact from photons, which don't leave a trail. Positrons (anti-electrons) behave just like the electrons but curl in the opposite way because they have the opposite charge. (One such electron-positron pair is highlighted.)

The collider ring as a boson, whose overall contention could have been seen in the total energy involved, and the dispensing to those extra dimensional perspectives within the "natural world" of our settings? Have I misunderstood the values of the Pierre Auger experiment to see better, then we had seen before, not to have seen a topological question about how one would interpret the sphere with one hole, as a donut? What values circles then?

Decoherence represents an extremely fast process for macroscopic objects, since these are interacting with many microscopic objects in their natural environment. The process explains why we tend not to observe quantum behaviour in everyday macroscopic objects since these exist in a bath of air molecules and photons. It also explains why we do see classical fields from the properties of the interaction between matter and radiation.

Angels/demons seem to make there way into view here? Yet in the world of Dirac might he seen the consequence of possible pathways in the construction of the matrix involved and intoduced the i of questionable directives as results in the arrangement of that same matrix?? Feynman took over for sure in his toy models.

Then of course I come across this statement previous and I am back to scratching my head. Oh boy!

You might imagine antimatter as a possible temporary storage medium for energy, much like you store electricity in rechargeable batteries. The process of charging the battery is reversible with relatively small loss. Still, it takes more energy to charge the battery than what you get back out of it. For antimatter the loss factors are so enormous that it will never be practical.

If we could assemble all the antimatter we've ever made at CERN and annihilate it with matter, we would have enough energy to light a single electric light bulb for a few minutes.

Hmmmm......more confusion again.:)



What value from such gravitonic perceptions from the modifications if events such as these above are not held to the dynamical nature of the spacetime fabric itself?

Rayleigh Scattering

Over top of this whole post, I have wrapped it in context as if the fifth dimension. It is being expresed as part of a larger understanding of how such grvatons in their congergations might have been percieved? Yet Lubos cautions this perspective. I don't understand why.

Aaron Bergman on Dec 10th, 2005 at 1:46 am

The S-matrix is contact with (hypothetical) experiments. Most of the things we compute in QFT are S-matrix elements. The fact that we’re not really living in a region with free |in> and |out> states doesn’t stop us from figuring out what happens in a collider.

Some now looking at the relation to what can be constitued to interactions between the nature of the Sun such relation woud have spelt opportunities of what John Ellis might have expressed in the Pierre Auger experiments? NON?

As I read about this particular subject of the S-matrix I choose this particluar subject to get my head around it, and still, might have been lacking in moving through this subject. But something triggered in my mind to a previous question raised, that I thought I would bring forward here.

Of course I am thinking about the calorimeters used in Glast and the cosmological depth, as well, in the LHC where the quantum nature is expressed as well. These cannot be taken together?

Gavin Polhemus on Nov 23rd, 2005 at 6:24 pm
When you look at a rainbow you see the arcs of color, often against a dark backdrop of clouds. You also see the grayish mist of the falling rain. Where does the mist appear brighter?

a) inside the rainbow
b) outside the rainbow
c) the brightness is the same inside and outside
d) it varies



While I am talking about "Heaven's ephemeral qualites" in the pictured link, there was also a link attached to it as well in that post. It would help explain this process in context of Gavin's question. I'm definitely listening, and the information is coming from various sources. You see this, as I bring those sources together here.

Lubos Motl:

String theory allows us to calculate the S-matrix (another example that we do call an "observable") for all particles in the spectrum which includes the scattering of gravitons. We don't have to insert our knowledge about the problematic "bulk" observables: string theory automatically tells us not only the right answers but also the right questions. "It is the S-matrix you should calculate, silly," she says. It also tells us what are the corresponding evolution observables for anti de Sitter space.

Someone may therefore convince you that the S-matrix is the only meaningful observable that has any physical meaning in a quantum theory of gravity. This sentence is both deep, if an appropriate interpretation is adopted, as well as discouraging.

What is most troubling then is that a simpe picture of the lensing that can occur in the the gravitational perspective, might have been enlisted in how we see this light travel through to the CSL lensing that is being spoken too?

Simulating the joint evolution of quasars, galaxies and their large-scale distribution

The cold dark matter model has become the leading theoretical paradigm for the formation of structure in the Universe. Together with the theory of cosmic inflation, this model makes a clear prediction for the initial conditions for structure formation and predicts that structures grow hierarchically through gravitational instability. Testing this model requires that the precise measurements delivered by galaxy surveys can be compared to robust and equally precise theoretical calculations. Here we present a novel framework for the quantitative physical interpretation of such surveys. This combines the largest simulation of the growth of dark matter structure ever carried out with new techniques for following the formation and evolution of the visible components. We show that baryon-induced features in the initial conditions of the Universe are reflected in distorted form in the low-redshift galaxy distribution, an effect that can be used to constrain the nature of dark energy with next generation surveys.

The poster shows a projected density field for a 15 Mpc/h thick slice of the redshift z=0 output. The overlaid panels zoom in by factors of 4 in each case, enlarging the regions indicated by the white squares. Yardsticks are included as well. The postscript file has been produced for A0 format. Beware of it's huge size!

Now Lubos mentions the bulk relation here, and I wonder why such a take on a gathering of graviton perceptions would not help to see Heaven's ephemeral qualites as consequences of the pathways this light can take?

Mine is a simple way in which to understand such graviton scattering which might have "some reasoning?" behind it that would have said the blackhole concentration of such a photon persepctive woud have held greater consequence to the blackhole position in the universe? non?

Rayleigh scattering using the S-matrix

For the example of sunlight shining on the atmosphere, the S-matrix predicts that shorter-wavelength light (blue end of the spectrum) will scatter at larger angles than longer-wavelength light (red end of the spectrum). And this is exactly what we see! Let me go through it. It helps to have a globe handy, perhaps using a pencil or straight piece of wire to simulate an incoming ray of sunlight; imagine a very thin layer over the surface which is the atmosphere. A small scattering angle means the light continues on nearly in the direction it started out in, while a large angle means close to perpendicular to the incoming direction.

Charlatan's Who Use Graviton?

Are Gravity people Charlatan's?:)I certainly don't think so.:)



well this is a good perspective with which one could move forward and explain it for us lay people here? :)

Lubos Motl:

The graviton is, on the contrary, an example of a correct derivation from semiclassical gravity - a legitimate approximate unification of GR and QM. Its existence follows from the theories we have, even given some degree of ignorance of quantum gravity at higher energies, and at the semiclassical level, it is absolutely analogous to the photon.

The only difference is the value of the spin, the geometric interpretation of the graviton, and ultraviolet divergences from loops.

I might have had wrong ideas here about what the graviton as a force carrier "proposed?" To exemplified what gravity is...as a further extension of the theory of general relativity? Lubos sets it straight then on such joinings.

This is the crucial difference between the dark energy and modified gravity hypothesis, since, by the former, no observable deviation is predicted at short distances," Dvali says. "Virtual gravitons exploit every possible route between the objects, and the leakage opens up a huge number of multidimensional detours, which bring about a change in the law of gravity."

Dvali adds that the impact of modified gravity is able to be tested by experiments other than the large distance cosmological observations. One example is the Lunar Laser Ranging experiment that monitors the lunar orbit with an extraordinary precision by shooting the lasers to the moon and detecting the reflected beam. The beam is reflected by retro-reflecting mirrors originally placed on the lunar surface by the astronauts of the Apollo 11 mission.

I myself might find it nice to have the origins of how this graviton came about. How one might be mistaken to have seen the bulk as a teaming with them(blackholes?), and such congregations telling, about places stronger then, while others are weaker.

How telling is the photon as it travels through these spaces? What was the initial trigger that set things free as Hawking radiation? Some analogies there to consider as well:)

So it would be nice then if one could find analogies that would sit well and sink deep. You know that the general public likes to think easy, and not finding relevant all the dressings of mathematical explanations. Or do they?

Is it wrong to move so far ahead theoretically to be called a charlatan, by those who recognized the limitiations of experimentally proving it?

Oh My God Particle-Revisited

I just wanted to drop this link here for now.

The animation shows schematically the behavior of the gas molecules in the presence of a gravitational field. We can see in this figure that the concentration of molecules at the bottom of the vessel is higher than the one at the top of the vessel, and that the molecules being pushed upwards fall again under the action of the gravitational field.

Gerard "t Hooft:

The Holographical Mapping of the Standard Model onto the Blackhole Horizon

Interactions between outgoing Hawking particles and ingoing matter are determined by gravitational forces and Standard Model interactions. In particular the gravitational interactions are responsible for the unitarity of the scattering against the horizon, as dictated by the holographic principle, but the Standard Model interactions also contribute, and understanding their effects is an important first step towards a complete understanding of the horizon’s dynamics. The relation between in- and outgoing states is described in terms of an operator algebra. In this paper, the first of a series, we describe the algebra induced on the horizon by U(1) vector fields and scalar fields, including the case of an Englert-Brout-Higgs mechanism, and a more careful consideration of the transverse vector field components.

So we are still looking at the horizon here.

In reference to the God Particle. This was first revealed in the 1991 Fly's eye experiment.

Oh-My-God particle

On the evening of October 15, 1991, an ultra-high energy cosmic particle was observed over Salt Lake City, Utah. Dubbed the "Oh-My-God particle" (a play on the nickname "God particle" for the Higgs boson), it was estimated to have an energy of approximately 3 × 1020 electronvolts, equivalent to about 50 joules—in other words, it was a subatomic particle with macroscopic kinetic energy, comparable to that of a fastball, or to the mass-energy of a microbe. It was most likely a proton travelling with almost the speed of light (in the case that it was a proton its speed was approximately (1 - 4.9 × 10-24)c – after traveling one light year the particle would be only 46 nanometres behind a photon that left at the same time) and its observation was a shock to astrophysicists.

Since the first observation, by the University of Utah's Fly's Eye 2, at least fifteen similar events have been recorded, confirming the phenomenon. The source of such high energy particles remains a mystery, especially since interactions with blue-shifted cosmic microwave background radiation limit the distance that these particles can travel before losing energy (the Greisen-Zatsepin-Kuzmin limit).

Because of its mass the Oh-My-God particle would have experienced very little influence from cosmic electromagnetic and gravitational fields, and so its trajectory should be easily calculable. However, nothing of note was found in the estimated direction of its origin.

Why was it necessary to invoke God here as you did Wolfgang? This was around for some time, and now, such references have found their way into particle collisions perspectives? :)

Quantum gravity is the field devoted to finding the microstructure of spacetime. Is space continuous? Does spacetime geometry make sense near the initial singularity? Deep inside a black hole? These are the sort of questions a theory of quantum gravity is expected to answer. The root of our search for the theory is a exploration of the quantum foundations of spacetime. At the very least, quantum gravity ought to describe physics on the smallest possible scales - expected to be 10-³⁵ meters. (Easy to find with dimensional analysis: Build a quantity with the dimensions of length using the speed of light, Planck's constant, and Newton's constant.) Whether quantum gravity will yield a revolutionary shift in quantum theory, general relativity, or both remains to be seen

One needs to keep perspective on what is happening here, and as a layman, it is extremely difficult. Yet, do I seem to understand what these season vets are doing? More then just reading the NYT times for sure :)

The Fly's Eye and the Oh My God Particle John Ellis was instrumental in opening up perspective here. What is happening outside of collision reductionist processes of the colliders

Gott Time?

Okay Clifford, enough's enough. Some of like to be genuine and eloquent in our speech as well. So I'll try my best.

You had to understand that without this inductive/deductive topological sense, this would not help one to identify what Greene is saying. You had to know what this represent in our valuations of time as we look throughout the universe? Etc, etc, etc:)

Brian Greene:

it turns out that within string theory ... there is actually an identification, we believe, between the very tiny and the very huge. So it turns out that if you, for instance, take a dimension - imagine its in a circle, imagine its really huge - and then you make it smaller and smaller and smaller, the equations tell us that if you make it smaller than a certain length (its about 10-33 centimeters, the so called 'Planck Length') ... its exactly identical, from the point of view of physical properties, as making the circle larger. So you're trying to squeeze it smaller, but actually in reality your efforts are being turned around by the theory and you're actually making the dimension larger. So in some sense, if you try to squeeze it all the way down to zero size, it would be the same as making it infinitely big. ...

I notice this comment previous about Richard Gott. I returned to my archives in the internet world for information that I had already cataloged. How and why, I will not say right now, but it is about the prospect of the "future" and about where we had been in our "past."

Imagine then--and put aside the engineering problems for a moment--a machine big enough to walk into. As you would walk forward within the confines of the light beam, (see diagram below) you'd have the impression of moving forward, but because of the space-time vortex, you'd actually be moving backward. You could walk back through time--maybe even passing yourself as you entered the ring.

(does this sound familiar Steven?)

So who is Richard Gott, but first, some of you good readers might recogize what Sean has to say about time travel?

Time Travel in Einstein's Universe: The Physical Possibilities of Travel through Time

The notion of closed timelike curves in the real world is hard to reconcile with our intuitive understanding of causality. Perhaps one can find global solutions to general relativity incorporating closed timelike curves. These, in effect, would be time machines. But it may be impossible to construct such a system in a local region of space. Theorems along these lines were proved by Frank Tipler in the 1970s. Tipler assumed that the energy density was never negative and showed that closed timelike curves could never arise in a local region without also creating a singularity. This was reassuring, as we could hope that both the singularity and the closed timelike curves were hidden behind an event horizon (although this was not part of the proof).

Now I spoke in regards to the name of Ronald Mallet for a reason, other then to insight hope into people, and tell them to disregard the color of skin. That the mind still works in all it's wonders whether in a male or female, black, white, yellow or green. Okay, so I went to far in the color dynamics, but you get my jest, eh?

Of how disadvantaged views, will create color in our world perceptions. We just have to rise above this(step back from the experience)and put it into perspective. The sameness with which all of us have in this humanistic valuation of character and such, arising from a historical past. Are your words your own in the makeup of advice you give, or is it from the mother and fathers, as parents who speak through you?

Will We Travel Back (Or Forward) in Time? by RICHARD GOTT III

Einstein proved we can travel forward by moving near light speed. Backward requires a wormhole, cosmic string and a lot of luck
Do the laws of physics permit time travel, even in principle? They may in the subatomic world. A positron (the antiparticle associated with the electron) can be considered to be an electron going backward in time. Thus, if we create an electron-positron pair and the positron later annihilates in a collision with another, different electron, we could view this as a single electron executing a zigzag, N-shaped path through time: forward in time as an electron, then backward in time as a positron, then forward in time again as an electron.

So no, it is not just about going back in time and finding out where we reiterate the views embedded within our own consciousness, but show, what has happened to the individual as a inductive/deductive feature progresses forward in time.

Do such loops work in our makeup? Trust me when I say it is extremely difficult to change what has already happened in terms of our historical experiences. Yet, the advancement of views in that future when meeting that historical past, is the new mode of experimental basis. Which we will in this case refer to as scientific sensibility? How many reminders do we actually need on what is "reality" and what is fictional?

So lets say for instance, that in Young's experimental travel of the photon, having going into the nether world, what path had it taken, to become the backdrop on that screen? It had to incorporate signatures and we all understand the Hydrogen spectrum do we not? The Electromagnetic Spectrum?

Ah so we understand do we about leaving signatures? Yes this is part of the history I am talking about. Have I extended it metaphorically? Yes, you betcha.

You have to embed this kind of thinking in order for foundational perspectives to change the way you perceive life on a grander scale. Not egotistical evolution, but of one that model consumption does to you about how we open new doorways to insightfulness and change in what we had always perceived?
