Window on the Universe

Michio Kaku:
I like to compare it to wandering in the desert, and stumbling over a tiny pebble. When we push away the sand, we find that this "pebble" is actually the tip of a gargantuan pyramid. After years of excavation, we find wondrous hieroglyphics, strange tunnels and secret passageways. Every time we think we are at the bottom stage, we find a stage below it. Finally, we think we are at the very bottom, and can see the doorway.

One day, some bright, enterprising physicist, perhaps inspired by this article, will complete the theory, open the doorway, and use the power of pure thought to determine if string theory is a theory of everything, anything, or nothing.

Only time will tell if Einstein was correct when he said, "But the creative principle resides in mathematics. In a certain sense, therefore, I hold it true that pure thought can grasp reality, as the ancients dreamed."

Consider any physical system, made of anything at all- let us call it, The Thing. We require only that The Thing can be enclosed within a finite boundary, which we shall call the Screen(Figure39). We would like to know as much as possible about The Thing. But we cannot touch it directly-we are restrictied to making measurements of it on The Screen. We may send any kind of radiation we like through The Screen, and record what ever changes result The Screen. The Bekenstein bound says that there is a general limit to how many yes/no questions we can answer about The Thing by making observations through The Screen that surrounds it. The number must be less then one quarter the area of The Screen, in Planck units. What if we ask more questions? The principle tells us that either of two things must happen. Either the area of the screen will increase, as a result of doing an experiment that ask questions beyond the limit; or the experiments we do that go beyond the limit will erase or invalidate, the answers to some of the previous questions. At no time can we know more about The thing than the limit, imposed by the area of the Screen.

Now you have to understand something here that the views of those who push our perceptions have gone even further then this, in how we look at the universe. I am showing you work that was progressing from understanding and bringing together what was going on then in 2004, to show you indeed that such an progression has taken place.

I also point out where "Conformal Field Theory" has planted itself, as we look at the images of Bekenstein bound. Such determinations and the roads taken by Strominger point specifically to what we can measure and what we have yet to measure. This did nt relegate any theoretcial view to the "garbage dump" but allowed visionaries to see beyond the SUN/Earth relation in Lagrangian views.

ISCAP will demonstratively help you "adjust your view" in a cosmological re-adjustment that is necessary. Not only from Glast views that arose from some fantasy, but culminates today in the use of a scientific device(calorimeter) for such measures.

In Gamma Ray detection and the Early Universe I point the direction in how Glast in it's preparation has given us new views on how we look at the universe.

Dust torus around a supermassive black hole
The Astrophysical Journal, in an article titled "Integral IBIS Extragalactic survey: Active Galactic Nuclei Selected at 20-100 keV", by L. Bassani et al., published on 10 January 2006 (vol. 636, pp L65-L68).


Meanwhile, the NASA team is now planning to extend his search for hidden black holes further out into the universe. "This is just the tip of the iceberg. In a few more months we will have a larger survey completed with the Swift mission. Our goal is to push this kind of observation deeper and deeper into the universe to see black hole activity at early epochs. That’s the next great challenge for X-ray and gamma-ray astronomers," concluded Beckmann.


Sun Earth Relation

Part of devloping this vision was to see in ways that the Grace satelitte allowed you to see. In what use "climate functions were happening" within the earth's atmosphere how it was being regarded. Time clock functiosn are necessary views, even within this context and such mapping allowed you to see th eearth as it had never been seen before.



No longer is it the surprize of the "first man to step out in space" to see such a blue marble and be aw struck by it's beauty. Now we have progressed in the same views that I allude too beyound what glast has done. Glast is your measure for now. Mine, and others, excell beyond this. As I show you why.

Dr. Mark Haskins:
On a wider class of complex manifolds - the so-called Calabi-Yau manifolds - there is also a natural notion of special Lagrangian geometry. Since the late 1980s these Calabi-Yau manifolds have played a prominent role in developments in High Energy Physics and String Theory. In the late 1990s it was realized that calibrated geometries play a fundamental role in the physical theory, and calibrated geometries have become synonymous with "Branes" and "Supersymmetry".


Now how abtract these views that I will show you to think indeed "theoretcial surmize exists for the potential to push perception." Then, I will give you a real image to ponder, as satellites now progress through this superhighway.

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.


In order to understand this sun/earth relation, you needed to see beyond what Glast had to impart to you. Yet, I do not say that it is irrelelavnt such experimental fashion to help us see even further. You understand this now?

So now, I'll show you what the universe looks like.

Diagram of the Lagrange Point gravitational forces associated with the Sun-Earth system. WMAP orbits around L2, which is about 1.5 million km from the Earth. Lagrange Points are positions in space where the gravitational forces of a two body system like the Sun and the Earth produce enhanced regions of attraction and repulsion. The forces at L2 tend to keep WMAP aligned on the Sun-Earth axis, but requires course correction to keep the spacecraft from moving toward or away from the Earth.


Now having this perspective in place, I am telling you what this does for perception, had I not carefully taken you through the roads to discovery. What the scale for gravity does for us in our estimation of what that universe actually looks like, when you put on glasses that change the very ideas of how we see.

While you may see refracting of the pencil in a glass of water, you may also see that the grvaiational relation is also apparent inhow we look at the universe?

If you do not think about the force carrier of the gravity then such extension to the standard model will only hold so much for you, while others in vision had been extended far beyond what you are accustom.

A Better Researcher, Not a Cynic...Yessss?:)

Sometimes there are wiser words then my own, to show what is "healthy and happy" with the research into quantum gravity? "A cynic" needs to wipe the spit from their chin, while recogizing what is really going on? We want a well balanced approach.

Approaches to the Quantum Theory of Gravity by the PI Institute

Two methods evolved in the theory of elementary particles to describe such quantized flux tubes. The one, called the loop method, studies them using the basic laws of electricity and magnetism, combined with quantum theory. The second, called string theory, postulates that the quantized flux tubes may be treated as fundamental in their own right, and the laws of electricity and magnetism derived from them.

Many theorists believe that these two points of view are actually equivalent—just different ways of studying the same thing from different points of view. The idea that they are the same is called duality, which here, as in other areas, signals that the same object is being studied with different ideas and methods.

Now, here is a SuperNova for Real

The Crab Nebula from VLT Credit: FORS Team, 8.2-meter VLT, ESO



Now the "ultimate proof" is to hold in our hands the matters defined by objects. This is the culmination of all dimensional perspectives, being "condensed to the moment" we hold the stardust samples in our hands. In that case, it may be of a meteorite/comet in passing?

Now we are going back to our computers for a moment here.

Now we know what can be done in terms of computer programming, and what simulations of events can do for us, but what happens, when we look out into space and watch events unfold as they do in our models?

Interaction with matter
In passing through matter, gamma radiation ionizes via three main processes: the photoelectric effect, Compton scattering, and pair production.


Photoelectric Effect: This describes the case in which a gamma photon interacts with and transfers its energy to an atomic electron, ejecting that electron from the atom. The kinetic energy of the resulting photoelectron is equal to the energy of the incident gamma photon minus the binding energy of the electron. The photoelectric effect is the dominant energy transfer mechanism for x-ray and gamma ray photons with energies below 50 keV (thousand electron volts), but it is much less important at higher energies.
Compton Scattering: This is an interaction in which an incident gamma photon loses enough energy to an atomic electron to cause its ejection, with the remainder of the original photon's energy being emitted as a new, lower energy gamma photon with an emission direction different from that of the incident gamma photon. The probability of Compton scatter decreases with increasing photon energy. Compton scattering is thought to be the principal absorption mechanism for gamma rays in the intermediate energy range 100 keV to 10 MeV (megaelectronvolts), an energy spectrum which includes most gamma radiation present in a nuclear explosion. Compton scattering is relatively independent of the atomic number of the absorbing material.
Pair Production: By interaction via the Coulomb force, in the vicinity of the nucleus, the energy of the incident photon is spontaneously converted into the mass of an electron-positron pair. A positron is the anti-matter equivalent of an electron; it has the same mass as an electron, but it has a positive charge equal in strength to the negative charge of an electron. Energy in excess of the equivalent rest mass of the two particles (1.02 MeV) appears as the kinetic energy of the pair and the recoil nucleus. The positron has a very short lifetime (about 10-8 seconds). At the end of its range, it combines with a free electron. The entire mass of these two particles is then converted into two gamma photons of 0.51 MeV energy each.


I wanted to include this information about Gamma Rays first so you understand what happens in space, as we get this information. I want to show you that there is faster ways that we recognize these events, and this includes, recognition of what the spacetime fabric tells us from one place in the universe, to another.

Does it look the same? Check out, "Going SuperNova 3Dgif by Quasar9"

Now, take a look at this below.

Four hundred years ago, sky watchers, including the famous astronomer Johannes Kepler, were startled by the sudden appearance of a "new star" in the western sky, rivaling the brilliance of the nearby planets. Now, astronomers using NASA's three Great Observatories are unraveling the mysteries of the expanding remains of Kepler's supernova, the last such object seen to explode in our Milky Way galaxy


What can we learn about our modelling capabilties, and what can we learn about the events in space that need to be further "mapped?" How shall we do this?

Gamma ray indicators prepared us for something that was happening. Now with this "advance notice" we look back, and watch it unfold?

A new image taken with NASA's Hubble Space Telescope provides a detailed look at the tattered remains of a supernova explosion known as Cassiopeia A (Cas A). It is the youngest known remnant from a supernova explosion in the Milky Way. The new Hubble image shows the complex and intricate structure of the star's shattered fragments. The image is a composite made from 18 separate images taken in December 2004 using Hubble's Advanced Camera for Surveys (ACS).


If advance indication are possible besides gamma ray detection, then what form would this take? Could we map the events as we learn of what happen in LIGO or LIsa operations, and how the "speed of light" is effected in a vacuum?

Now this comes to the second part, and question of indications of information released to the "bulk perspective" as the event unfolds as this SuperNova is.

Bulk:
Note that in the type IIA and type IIB string theories closed strings are allowed to move everywhere throughout the ten-dimensional space-time (called the bulk), while open strings have their ends attached to D-branes, which are membranes of lower dimensionality (their dimension is odd - 1,3,5,7 or 9 - in type IIA and even - 0,2,4,6 or 8 - in type IIB, including the time direction).


Now advancement in model assumption pushes perspective where it did not exist before.

You had to understand the nature of "GR" in pushing perspective, in the way this post is unfolding. Gamma ray indicators, are events that are "tied to the brane" and in this sense, information is held to the brane. The "fermion principle" and identifcation of Type IIA and IIB is necessary, as part of the move to M theory?

Thus when we look at Gamma rays they are not "separate from the event" while the bulk perspective, allows geoemtrics to invade the "new world" beyond the confines of non-euclidean geometries.

As I pointed out, the succession of Maxwell and all the eqautions (let there be light) are still dveloped from the center outwards, and in this perspective gravitational waves wrap the event. Thus the "outer most covering" is a much higher vision and dynamical nature, then what we assume as "ripples in space."

Bulk perspectve is a necessary revision/addition to how we think and include gravitational waves, by incorporating the "gravitonic perception" as a force carrier and extension of the Standard model.

While it has been thought by me to include the "Tachyon question", as a faster then light entity, the thought is still of some puzzlement that this information precedes the gamma ray detection, and hence, serves to elucidate the understanding of our perceptions of the early events as they unfold, as a more "sounding" reason to how we look at these early events?

If those whose views have been entertaining spacetravel, as I have exemplified in previous post, then it was of some importance that model enhancement would serve to help the future of spacetravel in all it's outcomes, as we now engaged, as ISCAP is engaging.

    A Constant that Isn't Constant?

    Now I am wrting this because some are persistent about the speed of light.

    I have looked at this and tried to accompany this thinking with actual work that has been put out there, and that has developed along these lines.

    I will give a list of links and thiking that I had archived for looking at this issue and explain as best I can what one must look for.

    Since the 1930s physicists have discussed whether the constants that appear in the equations for the fundamental laws of physics--such as the speed of light in vacuum and the electron charge--are actually constant. If they have changed over time, nature may have worked in different ways at different times, even if the equations themselves have remained fixed. Modern theories that attempt to unify gravity with the other fundamental forces leave room for such a time-dependence. But it's not easy to look for the effect. If the speed of light were slowly decreasing, for example, we might never know it, because our measuring apparatus might be shrinking at the same time.

    John Webb, of the University of New South Wales in Australia, and his colleagues, focused on the fine structure constant, which goes by the Greek letter alpha, because it has no units and is independent of any measurement system. Its current value of roughly 1/137 could not have been very different in the past, as that would have spelled trouble for our very existence. A variation in alpha by more than a factor of ten would imply that carbon atoms could not be stable, and organic life could not have arisen.


    So I'll deal first with the Fine Struture Constant and what I have got here. Stories in the news reflect at a fundamenatl level what is going onin the society of scientists? Whether a journalistic flavour is good or not, the basis of these myths propogated, if they are ever relegated to the "weird" or something not quite right, then one questions whether such journalistic behavior is very good?

    But like myths, we look past the haze and fog to try and discern why such impulse and flavour was ever drawn to the topic at hand, and what is really going on in the society of scientists.


    Change's in the Fine Structure Constant?

    The world's most precise atomic clocks are now made from "atomic fountains". A gas of atoms within a vacuum chamber is trapped by a set of intersecting laser beams and cooled to a temperature close to absolute zero. The ball of atoms is then tossed vertically into the air by changing the frequency of the lasers and it passes through a microwave cavity on its way up and also on its way down as it falls under gravity. The whole process is then repeated.


    Part of this attraction for me, was what was called "resonance curve."

    So let's move on here.

    As Van Den Broeck concludes: "
    The first warp drive is still a long way off but maybe it has now become slightly less improbable.
    "

    An idea for achieving faster-than-light travel suggested by the Mexican theoretical physicist Miguel Alcubierre in 1994.1 It starts from the notion, implicit in Einstein's general theory of relativity, that matter causes the surface of spacetime around it to curve. Alcubierre was interested in the possibility of whether Star Trek's fictional "warp drive" could ever be realized. This led him to search for a valid mathematical description of the gravitational field that would allow a kind of spacetime warp to serve as a means of superluminal propulsion...


    But there was a problem for me as I looked at this. I mean, if something is to attain the "speed of light" what happens to the ship? Of course along the way you meet people and learn things, and they extend the thinking.

    Does it change what we know?

    The ESAA group was founded with the ever present human nature of exploration in mind. The ultimate goal of the group is to physically explore the outer most human reaches, with an emphasis on intellectual exploration to achieve such goals. ESAA was founded by Fernando Loup, Edward Halerewicz, and David Waite to begin investigations into plausible methods to probe the outer reaches of known science. Fernado Loup a mathematician by trade was interested in exploring mathematical possibilities which may allow for superluminal travel. Edward Halerewicz a beginning physics student was primarily interested in popularizing advanced physical theories to encourage "outside the box thinking." David Waite a seasoned physics student was also interested in exploring the limits of known science and kept radical proposals grounded in real world physics. These three thinkers came together and discussed a recent theory within general relativity which would allow for serious superluiminal discussions.


    Here is more on the Group which is now called "Stardrive.

    Background on ESAA-Now Stardrive

    Paul Karl Hoiland - Feb 10, 2004 7:20 am
    In 1994 a Mexican mathematician, Miguel Alcubierre, discovered solutions to Einstein's equations which allow warps in the space-time metric to travel faster than the speed of light. But the proposal Dr. Alcubierre made was unrealistic on three basic grounds:

    1.) It required a huge amount of negative energy. 2.) It displayed no casual connection of the ship with the field itself. 3.) The exotic energy states involved violated certain quantum energy conditions like the AWEC.

    The ESAA group was founded with the ever present human nature of exploration in mind. The ultimate goal of the group is to physically explore the outer most human reaches, with an emphasis on intellectual exploration to achieve such goals.

    ESAA was founded by Fernando Loup, Edward Halerewicz, and David Waite to begin investigations into plausible methods to probe the outer reaches of known science. Fernado Loup a mathematician by trade was interested in exploring mathematical possibilities which may allow for superluminal travel. Edward Halerewicz a beginning physics student was primarily interested in popularizing advanced physical theories to encourage "outside the box thinking." David Waite a seasoned physics student was also interested in exploring the limits of known science and kept radical proposals grounded in real world physics. These three thinkers came together and discussed a recent theory within general relativity which would allow for serious superluiminal discussions.

    These discussions were opened in December 2000 to all that were interested within a yahoo discussion forum called the "Alcubierre Warp Drive" Club, named for the proposed superluimnal theory. The active members of the yahoo club then christened a name for themselves which became ESAA. The name ESAA was created by a club supporter named Simon Jenks, which is a Greek acronym for E Somino Ad Astra, or "From a Dream to the Stars." ESAA is an open and diverse group of individuals who are interested in seeking out nature's secrets to make some of mankind's most profound dreams come true.

    The ESAA group consist of physicists, mathematicians, engineers, students, and layman whose members are spread throughout the globe. All members have an equal say on group developments and collectedly the group has worked on three separate modifications to "Warp Drive" theories alone. In more recent times Dr. Paul Hoiland has become a valuable member of the ESAA group. Bringing much needed experience and wisdom to the group as well as creating the Journal of Advanced Theoretical Propulsion, based on the ESAA philosophy.

    ESAA History on the Warp Drive

    The online discussion forum the Alcubierre Warp Drive, began as a novel experiment, where members would answer questions that interested parties had for the new science. The early discussions within the Alcubierre Warp Drive began with philosophical debates, random brain storming, and slowly evolved to include mathematical discussions. It was during this new phase where Waite joined the club discussion, and we carefully began discussing the ramifications of his proposed warp drive. Unfortunately as soon as the mathematics became the bulk of the discussion, most of the philosophical debates were lost, but at this point Fernando Loup and Edward Halerewicz began to describe the possible consequences of Waite's space-time. During the discussion of Waite's idea the club was very grateful to receive advice and guidance from the very busy but gracious Dr. Alcubierre. And it was at this point that simply entertaining the idea of a new warp drive became a much more formal process, and a new theory of its own right began to form.

    The three early founders put together a paper which tried to levitate some of the problems with the "Alcubierre Warp Drive," (gr-qc/0009013) specifically reducing the amount of negative energy required within the theory. The paper was posted at the LANL ArXiv and was entitled "Reduced Total Energy Requirements for a Modified Alcubierre Warp Drive Space-time" (gr-qc/0107097). The paper also was not accepted for publication in established journals do to the inexperience of the authors in writing for academia. Also the paper was later found to have a few problems, e.g. the lapse function used to lower the energy requirements distorted time within the "warp bubble."

    Since the energy problem was dealt in more creative ways such as varying the warp bubbles parameters as suggested by Chris Van Den Broeck (gr-qc/9905084), the ESAA group decided to attack another problem. One of the problems raised with the Alcubierre Warp Drive was that its superluminal nature would be impossible to control. If this were the case then using Warp Drives for superluminal travel would be out of the question, new members joined the ESAA group and decided to construct another paper.

    The group wanted to know how superluminal motion would affect null geodesics and how this might be used as a clue to have control with a superluminal warp drive. The second paper put fourth by ESAA was entitled "A Causally Connected Superluminal Warp Drive Space-time (gr-qc/0202021), which proposed varying null geodesics to counter the superluminal problem. With this work several esteemed physicists gave there opinion on the paper, they largely argued against it because horizons will always form with superluminal motion. However ESAA argued against this reasoning as the horizons are still present they are simply moved by a dual light cone interpretation for space-time, the horizons just occur at another place. Expert opinion on this matter was that even if that held up, we couldn't show that a dual light cone interpretation is possible.

    From this point ESAA has had some heated arguments, which gained some enemies and made a few friends. It was however mutually agreed that such a paper would never be accepted in an existing journal and so no additional publication was pursed on this paper.

    The next paper proposed by the ESAA group was a paper to explore how Warp Drive space-time affect the geodesics of photons. From Alcubierre's original paper it is not to difficult to realize how the geodesics of photons become affected as was shown by Clarke, et. al (gr-qc/9907019). However a Portuguese researcher named Jose Natario showed that energy of the photons distorted by a warp drive would be lethal if traveling near the speed of light (gr-qc/0110086). This proved to be troubling as the popular press picked up on it as being the "Warp Drives are impossible," so ESAA decided to show how Warp Drives could still be possible with these "lethal" photons. It was found that a properly chosen dynamic space-time in several layers could act to slow the dynamic nature of the photons.

    This solution ESAA proposed was entitled "On the Problems of Hazardous Matter and Radiation at Faster than Light Speeds in the Warp Drive Space-time" (gr-qc/0207109). However some of the excited authors mistook the slowing dynamics for velocity, when in reality it is the energy that is reduced, so the photons are non lethal.

    Further inspection by ESAA and others have shown the lethal photons are fictitious as they exist with a Cauchy Surface, the photons energy doesn't change in the "warp bubble." There's just a frequency shift caused by the Cauchy region, since there is little interest in Warp Drives do the "toy" Alcubierre model ESAA has been slow in correcting this error. For these reasons this paper has not been considered for further publication, but again have shown that warp drives are mathematically feasible. However the ESAA solution dubbed a "shield" from its science fiction counter part does indicate the possibility of a dual light cone region as suggested by the second work which might warrant further investigation.



    There were questions then too about the "specific design of the ship" and the group wondered. What designs did they come up with?



    Doctor Paul Karl Hoiland - Jan 27, 2004 4:26 pm
    Fernando's general idea was to use certain effects to escape off the brane. But while his proposed testing of such with high energy particles could open the door to testing out aspect of the RS model in general, he basically discovered that it does not allow matter to escape the brane. I'm not sure who exactly pointed this out to him since he tended to exit our group again. During his time in our group I had discovered what he was looking at was a brane lensing effect. In studying such I discovered it modifies gravity and the path of particles on and off the brane.

    In the case of the extra dimension the length or volume is determined by the bulk cosmological constant(1) on both a local and global level. Gravity becomes higher dimensional at scales where

    1/r ¨ 1/r^1+N.

    But little has ever been mentioned of its modification of the on the brane Minkowski metric as well as the AdS one. Generally, what Fernando had noticed is that if you adjust the local Israel condition you can change the "warp factor" and that regular positive matter can adjust this. Its almost a pity he withdrew that third paper from GRG. With a bit of modification he had a perfect way to alter gravity in any local region which would have been a great test bed for certain Brane Models in general even if it did not support his hyperdrive idea.

    I think after looking at this idea one could achieve what to a remote observer was faster travel times even though you never exceed C in the local frame. It literally was the original ST style warp drive. You could travel through a Universe that is smaller with no violations of the laws of physics in either the local or remote region.



    Dr. Paul seems to have removed his links from one location to the next? Well, there are other names that can be followed up, if one thought to pursue this further.

    So what was Dr. Paul refering too?

    See:

    It is shown that our 3 + 1 Brane Einstein Universe is a trapped shell in a Higher Dimensional spacetime (Bulk). It is also shown that the Israel Condition acts like a pressure to trap matter in Einstein's Universe, and that if we overcome this pressure, we can make a particle leave Einstein's Universe and enter the Bulk. The conditions that allow the entrance to the Bulk permit its use to send signals or particles faster than the speed of the light, when “seen” from the Brane due to Brane Lensing. However, in the Bulk the particles remain subluminal. Our model differs from all the standard Braneworlds models, because all matter is trapped in this 3 + 1 Einstein Shell, independently of what the Standard Model might impose. What we propose is a new Braneworld Model using some of the features of the Chung-Freese Model, plus a way to overcome the pressure from the Israel Condition. Our model will remotely resemble the Davoudias Hewett, Rizzo modifications made to Randall-Sundrum Model that allow fermions (not only gravitons) to enter the Bulk, although we must outline that we are proposing a different idea.

    Numerical Relativity and Math Transference

    Part of the advantage of looking at computer animations is knowing that the basis of this vision that is being created, is based on computerized methods and codes, devised, to help us see what Einstein's equations imply.

    Now that's part of the effort isn't it, when we see the structure of math, may have also embued a Dirac, to see in ways that ony a good imagination may have that is tied to the abstractions of the math, and allows us to enter into "their portal" of the mind.

    NASA scientists have reached a breakthrough in computer modeling that allows them to simulate what gravitational waves from merging black holes look like. The three-dimensional simulations, the largest astrophysical calculations ever performed on a NASA supercomputer, provide the foundation to explore the universe in an entirely new way.

    According to Einstein's math, when two massive black holes merge, all of space jiggles like a bowl of Jell-O as gravitational waves race out from the collision at light speed.

    Previous simulations had been plagued by computer crashes. The necessary equations, based on Einstein's theory of general relativity, were far too complex. But scientists at NASA's Goddard Space Flight Center in Greenbelt, Md., have found a method to translate Einstein's math in a way that computers can understand.


    Already having this basis of knowledge availiable, it was important to see what present day research has done for us, as we look at these images and allow them to take us into the deep space as we construct measures to the basis of what GR has done for us in a our assumptions of the events in the cosmo.

    But it is more then this for me, as I asked the question, on the basis of math? I have enough links here to show the diversity of experience created from mathematical structures to have one wonder how indeed is th efinite idealization of imagination as a endless resource? You can think about livers if you likeor look at the fractorialization of the beginning of anythng and wonder I am sure.

    That has been the question of min in regards to a condense matter theorist who tells us about the bulding blocks of matter can be anything. Well, in this case we are using "computer codes" to simulate GR from a mathematical experience.

    So you see now don't you?:)

    Is Math Invented or Discovered?

    The question here was one of some consideration, as I wondered, how anyone could have delved into the nature of things and come out with some mathematcial model? Taken us along with the predecessors of endowwment thinking(imagination). To develope new roads. They didn't have to be 6 0r 7 roads Lubos, just a assumation. Sort of like, taking stock of things.

    So I may ask, "what are the schematics of nature" and the build up starts from some place. Way back, before the computer modeling and such. A means, by which we will give imagination the tools to carry on.

    So the journey began way back and the way in which such models lead our perspectives is the "overlay" of what began here in the postulates and moved on into other worldy abstractions?

    This first postulate says that given any two points such as A and B, there is a line AB which has them as endpoints. This is one of the constructions that may be done with a straightedge (the other being described in the next postulate).

    Although it doesn't explicitly say so, there is a unique line between the two points. Since Euclid uses this postulate as if it includes the uniqueness as part of it, he really ought to have stated the uniqueness explicitly.

    The last three books of the Elements cover solid geometry, and for those, the two points mentioned in the postulate may be any two points in space. Proposition XI.1 claims that if part of a line is contained in a plane, then the whole line is. In the books on plane geometry, it is implicitly assumed that the line AB joining A to B lies in the plane of discussion.


    One would have to know that the history had been followed here to what it is today.

    Where Non-euclidean geometry began, and who were the instigators of imaginitive spaces now that were to become very dynamic in the xyzt direction.

    All those who have written histories bring to this point their account of the development of this science. Not long after these men came Euclid, who brought together the Elements, systematizing many of the theorems of Eudoxus, perfecting many of those of Theatetus, and putting in irrefutable demonstrable form propositions that had been rather loosely established by his predecessors. He lived in the time of Ptolemy the First, for Archimedes, who lived after the time of the first Ptolemy, mentions Euclid. It is also reported that Ptolemy once asked Euclid if there was not a shorter road to geometry that through the Elements, and Euclid replied that there was no royal road to geometry. He was therefore later than Plato's group but earlier than Eratosthenes and Archimedes, for these two men were contemporaries, as Eratosthenes somewhere says. Euclid belonged to the persuasion of Plato and was at home in this philosophy; and this is why he thought the goal of the Elements as a whole to be the construction of the so-called Platonic figures. (Proclus, ed. Friedlein, p. 68, tr. Morrow)




    These picture above, belongs to a much larger picture housed in the Raphael rooms in Rome. This particular picture many are familiar with as I use part of it as my profile picture. It is called the "Room of the Segnatura."



    The point is, that if you did not know of the "whole picture" you would have never recognized it's parts?

    From the Stillness Born

    Can harmonic oscillators serve as a bridge between quantum mechanics and special relativity?





    "Daddy, is this the World," my young son asks, as we drive through the neighborhood with which we lived. This still sits deep in my conscious mind, as I tried to understand the scope of his vision, about reality. I looked at this small human being, and what he thougt of the world.

    Years pass, and born out the child's mind are things that were once asked of him. That if you wanted to "be" something in life, as to a vocation, what would that be?

    He was on stage, with the "rest of the people" as the hypnotist walked among them all and asked a question. They were all "highly open" to the suggestiveness of the question. Not knowing what my son was doing, as his arm was making this sawing movement, the hypnotist asked. My son replied, "I am a builder."

    He was young to know that he was really going to do? He was young to know that he would one day try this? But, from the results, you might conclude that he is indeed a builder?

    He has completed the roof lines here ,and in the following days the roofers will come and finished the roof. As well, we will be placing the doors and windows.

    Unfortunately I could not help him with the roof, and this seems fitting, that he finish this part of the job as the icing on cake.

    On the ledge



    I am one of those people if standing on the edge, becomes very disorientated. If one might of saw my reaction as I stood on the edge of the vastness with which my wife and I gazed upon the grand canyon, it was "this thing about heights" that makes itself known to me. That the closer I got, the lower, I would place myself to the ground. My comfort zone is to know that there is a solid place in my life that I can always hold onto, as one might begin to explore the vastness of the world. A railing/home to which one could hold on too.

    Out of it, new life emerges. That what what was once the seed of the design of life, becomes and became the children and their children. Our grandchildren.

    It is no great feat that the ages of the scientists "who endeavor now" speak about the world, are in their youths and are much as my own children. Quite capable, to face and handle the world with sound reasoning and judgement. Will become the "parents of life" as this is past on, from one generation to the next.

    The Proof is not Enough?

    It could not and did not happen without "energy" thrusting itself into the capability of what all things could become? You ask for proof? It is all around you.

    "What is a pipe?"



    So where is this "stillness," out of which all things are borne? If there is no basis from which for all such things to exists? What is space then, and I am first drawn to coordinated systems? The foundational perspective perhaps?



    Is it all such a muddle that you can't tell there is a pattern emerging from within the self? The "energy you have as to what plans and lessons you will engage and of course hidden amongst all this information you will make certain "conclusions?" You own that. If you take it inside, "you own it."

    But there is more to it for sure. There is more to it, in what we think of what is "inside" can be outside, and this exchange with reality, again forces us to ask? Where did it all begin?

    A condense Matter theorist might deal with the matters in a special kind of way? It also forms the basis of my thinking, and again, I am somewhat biased in my views. It colors this whole bloggery. The way in which I might look at Mendelev's view of the world in the most colorful and harmonical in realization?

    At What "Point" does the Universe Make itself Known?

    According to the basic laws of physics, every wavelength of electromagnetic radiation corresponds to a specific amount of energy. The NIST/ILL team determined the value for energy in the Einstein equation, E = mc2, by carefully measuring the wavelength of gamma rays emitted by silicon and sulfur atoms.


    This, was encapsulated in a "point before time and space(?), that explodes again into your mind, as if some universe coming into being? How could that "be?"

    Like a bubble perhaps, or like a universe that has reached it furthest reaches, collapses again, and where does the universe lead us, but back to "this point"?? Some event that has unleashed it's potential and spoke about the geometrics of, and we found that it lead back to "the time" where the universe again began?

    When primary cosmic rays collide, what allowed the secondary particles to emerge? What is cerenkov light emitted? ICECUBE.



    They can trace back the gamma rays to the original source? The gamma rays are not affected by the magnetic field? This allows them to trace back the history of the particles back to the original source? How do "they know" where it came from?

    There was a time when the realization existed that particle creation had no relation to what the universe did in it's first three minutes of Weinberg? Now, it has become Microseconds? Are you convinced now?

    Let's assume that you are, so what allowed us to go back to what any moment could be produced given the right set of circumstances? That what is out there is is also inside?

    We had to be able to go back to the beginning of the universe did we not?

    So what use models serve if they can not be applied at many levels and now we see the trail of young theorists move to other realms, sociologically driven, where their abilities are better used on wall street or the likes, because it just didn't make sense anymore to try and delve into it.

    Everyone knows that human societies organize themselves. But it is also true that nature organizes itself, and that the principles by which it does this is what modern science, and especially modern physics, is all about. The purpose of my talk today is to explain this idea.


    Or to see the science used in a destruction of a kind, that it's reverberation magnified tens of times, could be used from one plane load? Laughlins "exemplified page" is forever haunting in what these magnifications can become from a condensed matter theorist point of view?

    So how do ideas enter the mind? You create the Blank slate and endeavour to write the formula for aspects of creation? What "energy values" are these?


    Many physical quantities span vast ranges of magnitude. Figures 0.1 and 0.2 use images to indicate the range of lengths and times that are of importance in physics.



    But it's more then that, to think that the energy chaotic, is in it's extremes, would have no "organizational skills" to begin to manifest itself in it's very guises, that one might ask, "what use any energy put too?"

    So this becomes the pattern? A Pattern of destruction?

    No, not always. It can become a pattern for peace.:) A balance found(?) of the exchange, that "things" could be in a state of "becoming?" Allows yo to move inthe world in a different way. You can grow, as you extend the antenna out there, and allow what is out there to come inside?

    BigFoot: The Anomalistic Reality?

    The explanation of scientific development in terms of paradigms was not only novel but radical too, insofar as it gives a naturalistic explanation of belief-change. Thomas Kuhn




    What can we say to those who practice science and have been told, no anomalistic conditions can exist in reality? How will they "act" when they have been shaken at the very roots, assuming, such a thing can happen to them as a "observer" of what is "real" to them?



    What "if" their illusions have taken hold of them? What if, they jump into a river? Scientists are not like this? They see "everything?":)OuI! Non? They all looking for "truth" just like you, Lee Smolin. There are no causalities?

    Nature in Analog Models

    In condensed matter, one can construct systems where the propagation of long wavelength phonons (sound waves) is very similar to the propagation of a scalar field in a curved Lorentzian spacetime. Such systems are called 'analog models'. It is even possible to construct analogies to black holes in this manner, where the phonons that travel past a certain point cannot return. For example, consider a fluid where long wavelength phonons in the fluid propagate with speed cs, which is analogous to the speed of light in these models. Now put this fluid in a pipe and change the shape of the pipe such that the speed v of the fluid is faster than cs in one section and slower in an adjacent section. A phonon can travel "back against the current" only up to a certain point, where the the fluid speed equals cs. After that the fluid flow carries it down the pipe. This point in the pipe therefore mimics a black hole event horizon, from which nothing can escape. Other black hole features such as Hawking radiation are also present in these models. Since these models give an example of a system that has a fundamental structure at very short distances (where the fluid description breaks down), yet has a pseudo-Lorentz invariance at long distances.


    So forget about paradigmal change, and Kuhn's perspective about revolutonary change? A precursor to how things have always been done, now change, to become? Such an example is needed to push perspective unless you want to stay the way you have always been?

    Evidence of Dis-ease?



    Have we gotten so far to assume "the sickness" had indeed been caused by such theoretics and a "ventured mysticism," that the fault lied in those who venture forth and offer perspective and some who lacked visional meaning?

    So as a "painter" Dali added "dimension" to the tesserack of our talks?:)

    The artists begun to believe in the "mystical reality of life" and in so having succumbed to the death of all that has been forsaken(education), it will be strings that will lie at the root cause of this troubling disease?

    What "seeing" has overtaken all that we have currently surmized. Is it such an artist of people who help free us of our rigidity?

    I am trying to be sensitive as well here.

    Bigfoot Toe Analogy

    Backreaction: Lee Smolin's Trouble with Physics

    BEE said:
    Last night I had a nightmare! Bigfoot knocked at my door and wanted to talk to me about the existence of the string theory landscape. Still on east-coast time, I wiped off the sweat from my forehead but couldn't fall asleep again. I switched on my laptop, and decided its time to post the review on Lee Smolin's new book.


    I found this a very interesting perspective by "B" on the "Theory of Everything" and how this can manifest in the deeper part of the subconcious mind. Of course the mind tries to deal with the incredibility of the world? How shall we come to deal with it's anomalies, if "repeatability" will not sanction the observer?

    The unexpectedly hot output, if its cause were understood and harnessed, could eventually mean that smaller, less costly nuclear fusion plants would produce the same amount of energy as larger plants.


    QGP tunnelling? So where are these times being presented? What is accounting for the conditions which allow for such tunnelling? A cosmological preview perhaps which allows for "new physics" to emerge?

    Instead of the Newtonian inverse square law you’ll have an inverse fourth power law. This signature is being looked for in the ongoing experiments.


    What things will shock the scientist? Change the "foundational basis" of thinking about the quantum reality?

    The affect these things(?) can have on any mind is amazing, and of course, getting all the information is very important(observing what is wrong), so, we can assess what the heck is going on?

    It was six men of Indostan
    To learning much inclined,
    Who went to see the Elephant
    (Though all of them were blind),
    That each by observation
    Might satisfy his mind.

    The First approached the Elephant,
    And happening to fall
    Against his broad and sturdy side,
    At once began to bawl:
    "God bless me! but the Elephant
    Is very like a WALL!"


    The Second, feeling of the tusk,
    Cried, "Ho, what have we here,
    So very round and smooth and sharp?
    To me 'tis mighty clear
    This wonder of an Elephant
    Is very like a SPEAR!"

    The Third approached the animal,
    And happening to take
    The squirming trunk within his hands,
    Thus boldly up and spake:
    "I see," quoth he, "the Elephant
    Is very like a SNAKE!"

    The Fourth reached out an eager hand,
    And felt about the knee
    "What most this wondrous beast is like
    Is mighty plain," quoth he:
    "'Tis clear enough the Elephant
    Is very like a TREE!"

    The Fifth, who chanced to touch the ear,
    Said: "E'en the blindest man
    Can tell what this resembles most;
    Deny the fact who can,
    This marvel of an Elephant
    Is very like a FAN!"

    The Sixth no sooner had begun
    About the beast to grope,
    Than seizing on the swinging tail
    That fell within his scope,
    "I see," quoth he, "the Elephant
    Is very like a ROPE!"

    And so these men of Indostan
    Disputed loud and long,
    Each in his own opinion
    Exceeding stiff and strong,
    Though each was partly in the right,
    And all were in the wrong!


    What is happening in the trouble minds of the scientists as we have come to learn of their struggles to deal with the anomalistic(animalistic)world? :)The Jaquar, the elephant(how shall we describe quantum gravity)?

    Maybe it is a joke of "incredibility to some" knowing more then what we lay people know? Yet, with all that has been said here, where will you bury your experience? How shall it now manifest into your life? What will now "motivate" your science?



    "Diamagnetic situation" and what creates these holes in what runs consistently, and we see where such instances "float" the disc. How strange, had you not have arisen from the tribal forest life? To view the situations of all "science life" to see and know more then what taken for granted as thplane flew over head on first take?

    Einstein when given the compass saw something strange in his youth? We know better now what that was. All "lay people" are in their youth? All "lay people" can learn? As a "lay person" I will listen very hard to what you are saying.

    Fantastic journies



    A flight between "heaven and Earth?" Some cherish the Eagle for seeing.

    "Warren Seagull" is a wonderful bird? :) Parodies, will break us free?

    Early Universe Formation

    An Energy of Empty Space?

    Einstein was the first person to realize that empty space is not nothingness. Space has amazing properties, many of which are just beginning to be understood. The first property of space that Einstein discovered is that more space can actually come into existence. Einstein's gravity theory makes a second prediction: "empty space" can have its own energy. This energy would not be diluted as space expands, because it is a property of space itself; as more space came into existence, more of this energy-of-space would come into existence as well. As a result, this form of energy would cause the universe to expand faster and faster as time passes. Unfortunately, no one understands why space should contain the observed amount of energy and not, say, much more or much less.


    I had been doing some reading and some thoughts came to mind about the measures one may use to see how our universe is doing. While it is really early here for any great revelation :) it did seem that issues could arise in my mind, if we used the "distance" to measure what exactly the universe is doing.

    A Determinism at Planck Scale?

    I'll tell you why in a second and then leave for now, as I have to continue with finishing the "foundation" with my son. Getting ready for backfilling tomorrow.



    Andrey Kravtsov's computer modelling comes to mind, and how I was percieving early universe modelling in terms of a supersymmetrical state of existance. Holding this very idea in terms of this whole universe, it seemed to me, that the very "dynamical situation" and rise from such motivations, would have revealled principles as inherent in how "GR" would arise from this beginning. If the 5d consideration ha dbeen reduced to the 4 spacertime coordinated frame of reference, then what use any supersymmetrical state, or the motivation for such universe expressions?

    Scientists have detected a flash of light from across the Galaxy so powerful that it bounced off the Moon and lit up the Earth's upper atmosphere. The flash was brighter than anything ever detected from beyond our Solar System and lasted over a tenth of a second. NASA and European satellites and many radio telescopes detected the flash and its aftermath on December 27, 2004. Two science teams report about this event at a special press event today at NASA headquarters


    So there are two issues here that in my mind which make measurement extremely difficult. Two events within each other, that reveal something acute about the closeness of the beginnings in the universe, as very closely mappped to what exists now in our views revealled in GRB events



    It was further complicated in my mind by two more issues that hold reference to these high energy events releases, that layout the schematics drawings, that the new WMAP indication holds in regards to analogistical sounds, revealled as the underpinnings of movement within this same universe.

    So what about the WMAP and it's current reveallings?

    If such equillibrium states are recognized as they are in placing detectors to position. Wouldn't this also reveal an opportune time for how we see this information, and provide for quick travel?

    How did these "holes" create a problem for me?

    If energy from these events found the "fastest route," then what would any lensing have looked like, effected by the very influences that the photon's travelled held, unduly holding to a fifth dimensional view?

    The universe may of then looked like a swiss cheese? :)

    Within conventional big bang cosmology, it has proven to be very difficult to understand why today's cosmological constant is so small. In this paper, we show that a cyclic model of the universe can naturally incorporate a dynamical mechanism that automatically relaxes the value of the cosmological constant, including contributions to the vacuum density at all energy scales. Because the relaxation time grows exponentially as the vacuum density decreases, nearly every volume of space spends an overwhelming majority of the time at the stage when the cosmological constant is small and positive, as observed today.

    If gravity and light are joined in the fifth dimension, what would this mean?

    Harmonics will Color Your World?



    If you are a active participator of the very world around you, how is it, the makeup of high energy particle creations could not have included the standard model make up "harmonically described" does it not also apply to our "very thinking and conscious mind?" :)

    The Landscape “avant la lettre” by A.N. Schellekens

    The lowest harmonics correspond to the particles of the Standard Model, plus perhaps a few new particles. The higher harmonics correspond to an infinite series of particles that we can never observe, unless we can build a Planck Energy accelerator


    So of course the very basis of the thinking was drawn in my mind to the very subject enlisted by the minds of our predeccessors, to wonder, how this associative function could have ever been at the basis of how we may look at the World?

    Lee Smolin:
    In case it is not obvious, let me emphasize that harmonic oscillators are not relevent here, and can play no role in a background independent quantum theory, precisely because the division of a field into harmonic modes requires a fixed background metric. Thus, the physics of the problem REQUIRES an alternative quantization


    Of course it is never easy for me to understand what is going on while we have the issues of the background, versus, the non background, and this brings up the ole debates about positions and adoptives stances scientists have taken in regards to the "duality" of science's "quantum gravity" issues?



    Do I have a complete grasp of it. Absolutely not, while it forces me back to the issues, as to what is the basis of this "difference of opinion?"

    THE ANTHROPIC PRINCIPLE


    Leonnard Susskind and Lee Smolin


    While this is a conversation written by physicists for physicists, it should nonetheless be of interest for Edge readers as it's in the context of previous Edge features with the authors, it's instructive as to how science is done, and it's a debate that clarifies, not detracts.

    So by historically looking back, this is a reminder, about the ways in which science people are still looking at things, while holding their positions of thought today?

    SEan's meeting at PI, is a very interesting one becuase what it does is take the teacher and student scenario, and manifests the circumstance of clarification as to positions, while providing for a intuitive surge to present itself in the minds of it's participnats.

    So this debate then was held and it's relationship rememebered within this blog as to the basis of determination, about how we see the universe and all that is in it.

    Lee Smolin:

    The aim of this paper is to explain carefully the arguments behind the assertion that the correct quantum theory of gravity must be background independent. We begin by recounting how the debate over whether quantum gravity must be background independent is a continuation of a long-standing argument in the history of physics and philosophy over whether space and time are relational or absolute. This leads to a careful statement of what physicists mean when we speak of background independence. Given this we can characterize the precise sense in which general relativity is a background independent theory. The leading background independent approaches to quantum gravity are then discussed, including causal set models, loop quantum gravity and dynamical triangulations and their main achievements are summarized along with the problems that remain open. Some first attempts to cast string/M theory into a background independent formulation are also mentioned.

    The relational/absolute debate has implications also for other issues such as unification and how the parameters of the standard models of physics and cosmology are to be explained. The recent issues concerning the string theory landscape are reviewed and it is argued that they can only be resolved within the context of a background independent formulation. Finally, we review some recent proposals to make quantum theory more relational.


    So if someone saids that space is empty, I have a really hard time with it.
