Cyclic Universe Could Explain Cosmological Constant

Thanks Paul for pointing this article out here some time ago.

Physicists have proposed several theories to explain why Λ is so small. One of the most popular -- the "anthropic principle" -- states that Λ is randomly set and has very different values in different parts of the universe (figure 1). We happen to live in a rare region, or "bubble", where Λ has the value we observe. This value has allowed stars, planets and therefore life to develop. However, this theory is also unsatisfactory for many scientists because it would be better to be able to calculate Λ from first principles.


We understand where strings reside in terms of "microseconds" and the "arrow of time?"

Once we know that there is one de Sitter solution, it is easy to find many more of them by just changing the values of the fluxes. Sujay Ashok and Michael Douglas of Rutgers University have recently estimated the number of different solutions to be at least 10100, which indicates an extremely rich landscape with many mountains, valleys, oceans and even volcanoes. Each minimum-energy point represents a different universe, and the height of that point is the value of the cosmological constant for that universe. Viewing the solution this way, the probability that one of these universes has a cosmological constant that is as small as is indicated by current experiments is actually non-zero.





Hmmmm..... remember Higgins?

What is the False Vacuum?



Quantum Field Theory

Quantum Vacuum:
In classical physics, empty space is called the vacuum. The classical vacuum is utterly featureless. However, in quantum theory, the vacuum is a much more complex entity. The uncertainty principle allows virtual particles (each corresponding to a quantum field) continually materialize out of the vacuum, propagate for a short time and then vanish. These zero-point vibrations mean that there is a zero-point energy associated with any quantum field. Since there are an infinite number of harmonic oscillators per unit volume, the total zero-point energy density is, in fact, infinite. The process of renormalization is usually implemented to yield a zero energy density for the standard quantum vacuum, which is defined as no excitation of field quanta, i.e., no real particles are present. In other word, the quantum vacuum is at a state of minimum energy - the ground state.


You have to be able to envision this movement in what our universe is doing. What is WMAP saying? Other events say what, in the node/anti-nodal?

A Chladni plate consist of a flat sheet of metal, usually circular or square, mounted on a central stalk to a sturdy base. When the plate is oscillating in a particular mode of vibration, the nodes and antinodes set up form a complex but symmetrical pattern over its surface. The positions of these nodes and antinodes can be seen by sprinkling sand upon the plates;


The "quantum harmonic oscillator" and "zero point as a ground state, are the basis of my thinking. :)Energy densities. I needed a way in which to see these events unfolding in the universe. Why I look at WMAPing very seriously. Why I looked at the chaldni plate very early on.

Physically, the effect can be interpreted as an object moving from the "false vacuum" (where = 0) to the more stable "true vacuum" (where = v). Gravitationally, it is similar to the more familiar case of moving from the hilltop to the valley. In the case of Higgs field, the transformation is accompanied with a "phase change", which endows mass to some of the particles


If you look at things in this way I have covered a lot of ground work in terms of what the basis of this universe is? "Nothing," is a extremely hard thing for me to accept when I accept the quantum harmonic oscillator, as the basis of my thinking. I had to be able to describe what I was seeing. So "sound" in analogy became a very important aspect of my research. Became discriptive of what Higgin's the graviton is doing?

If you sprinkle fine sand uniformly over a drumhead and then make it vibrate, the grains of sand will collect in characteristic spots and figures, called Chladni patterns. These patterns reveal much information about the size and the shape of the drum and the elasticity of its membrane. In particular, the distribution of spots depends not only on the way the drum vibrated initially but also on the global shape of the drum, because the waves will be reflected differently according to whether the edge of the drumhead is a circle, an ellipse, a square, or some other shape.

In cosmology, the early Universe was crossed by real acoustic waves generated soon after Big Bang. Such vibrations left their imprints 300 000 years later as tiny density fluctuations in the primordial plasma. Hot and cold spots in the present-day 2.7 K CMB radiation reveal those density fluctuations. Thus the CMB temperature fluctuations look like Chaldni patterns resulting from a complicated three-dimensional drumhead that


String theory is only "topologically equivalent" to the shape and values of those events microscopically/macroscopically at a certain plac einthe unfolding universe? I learnt that the energy densities flunctuations, would give meaning to the place dynamically and geometrically speaking, to the place in time, that is unfolding. What evidence do you have for that if "Higgin's" is strong in some event places and not in others? :)

The star Eta Carina is ejecting a pair of huge lobes that form a "propeller" shape. Jet-like structures are emanating from the center (or "waist"), where the star (quite small on this scale) is located.


Yes, there are many event shapes and they are diverse. But they happen within context of a "larger false vacuum" scenario as I am explaining it, while they make their way to what is "True?"

I had to "go further" then the microseconds, strings inhibit?

The plates can be made visible by mounting a mirror behind the row of plates, angled so that the top of the plates are visible to the audience (same idea as in Polarization by Scattering). Create the optimum angle for the front rows, as the back rows will be looking down on the plates anyway. Make sure the cello bow is nice and tactile by treating it with rosin before the performance. Sprinkle the sand on the plates so that it forms an even cover. Don't overdo the amount.

Emergence: A Point in Spacetime

We used to think that if we knew one, we knew two, because one and one are two. We are finding out that we must learn a great deal more about 'and'."
- Sir Arthur Eddington (1882-1944)



Foundational perspectives are important to me, and are part and parcel of a larger frame of thinking that comes into materiality.



What basis then leads such thinking, that something could manifest from another place and become the material reality with which we deal? I know this is about "what is in the now," yet such recognition of what is "chaotic and has complexity" now becomes an organizational pattern. What is "chaos theory?"

From the untold many constituents in the bulk perspective, "Higgin's" has some new found ways in which he can express himself. He see's new ways of travel in the universe?

What emergent properties would have such conditions and gatherings have on routing new universe from tunnelling found created within cosmological events? Which if reduced too, as QGP states of existance, would produce similar resulting anomalies encountered in superfluid state realities?

Since he is beyond what we are accustom too of the Standard model, then what value does Higgin's play as he is born to the level with which he now embues all of creation. He is strong on "some points," then others?

The Unfolding Universe



There is but one kind of entropy change. Entropy change is due to energy dispersal to, from, or within a system (as a function of temperature.), measured by microstate change: S = kB ln [microstates final / microstates initial ].


If you look to the arrow of time, and "the event from which it sprang," how did such strings become the basis of thinking along this road to what exists in the universe today? It has been assign "a place" in this segment of the time's growth within this universe, and we have been sent "back in time to the reductionsitic valuation" of what is seen in the colliders, to see what is emergent today. But what did they find at the beginning? What shall we find at "the beginning" of any universe?

What effect did strings have on this evolution?

The emergent universe

The breathtaking quality of emergence lies in its broad applicability, from ants to people, and from electrons to galaxies. We assume that we can sing and dance together because we are intelligent and coordinate our behavior, and so it is surprising to see the coordinated chirping of crickets, and shocking to discover that the same principles apply to mindless things such as water molecules arranging themselves in a crystalline structure to form ice. When you get enough things together, and they interact in just the right way, they suddenly shift to coherent behavior. Emergent principles may govern the smallest units of matter, as in electrons humming together within a superconductor, to the largest, as when entire galaxies clump into regular patterns. Scientists across multiple fields have found that such systems don't require a central ringleader directing the way – their self-organization is inevitable, due to the local interactions of nearest neighbors.

Emergence represents a revolutionary paradigm shift away from reductionism (the understanding of the world through understanding the component parts. Scientists working within the revolutionary paradigm of emergence study the organizing principles causing collective behavior across many disciplines.

The EUP is focusing on the following types of emergent systems


A point in space implies that such emergence into the spacetime co-ordiantes, have some "other dimensional relation" beyond what we are saying of 3+1? So of course I am enthralled by such an emergence and what could come into these spacetime coordinates.

So the universe in it's unfolding has certain attributes in it's early phases that amount to the conditions Sean Carroll may sees of it? If this is the case, then that valuation of the universe, in it's unfolding is doing what? It's temperature?

If you "wrap the whole of what this arrow of time is, in a geomtrical sense," then the strings and the time of the universe in "Sean's perspective" is inclusive?

So how do we say such a crunch is to happen? How does such thinking become part of our reasoning, to say that the universe will collapase on itself, and become something new? Will it ever?

Tegmark does not take to such "topological expressions of the universe," yet, if you look at the WMAP mapping of the universe what is it you see besides these points of expression, as some nodal and anti-nodal analogy to the cosmological events? Tunnels, through which we can travel? New energy, being distributed back into the universe, in the form of dark energy/matter?

We report results of the first strangelet search at RHIC. The measurement was done using a triggered data-set that sampled 61 million top 4% most central (head-on) Au+Au collisions at $\sNN= 200 $GeV in the very forward rapidity region at the STAR detector. Upper limits at a level of a few $10^{-6}$ to $10^{-7}$ per central Au+Au collision are set for strangelets with mass ${}^{>}_{\sim}30$ GeV/$c^{2}$.


If strangelets have been disproved then what "crazy thoughts" shall we now think of, in what constitutes the "new physics?" Tachyon condensation perhaps?

What is the "false vaccuum" to the "true," when it is geometrically expressed? :)

Clifford and The Singularity

Horatiu is referring to a mathematical similarity between the physics of the real world, which govern RHIC collisions, and the physics that scientists use to describe a theoretical, “imaginary” black hole in a hypothetical world with a different number of space-time dimensions (more than the four dimensions — three space directions and time — that exist in our world). That is, the two situations require similar mathematical wrangling to analyze. This imaginary, mathematical black hole that Horatiu compares to the RHIC fireball is completely different from a black hole in the real universe; in particular, it cannot grow by gobbling up matter. In other words, and because the amount of matter created at RHIC is so tiny, RHIC does not, and cannot possibly, produce a true, star-swallowing black hole.


See:

  • So how far back to the beginning, and if we had thought supersymmetry could exist, would it be in the most perfect fluid?

    I place this picture and article above so that one keeps perspective about the similarites of the "micro versus the macro" perspective and "not" that the "disaster scenario" could create the "large blackhole?" But wait?

    I am thinking in terms of what could create "the situations" for what is coming into being. Is it acummulative? I am not sure from the "many colldial events" that one could see happen? Hence my focus, to what not ony is created in the "collidal event," but to the cosmic particle colllsions as well. How rare are these? I speak on the "history of strangelets" from that point.

    Anyway onward here.

    Clifford:
    Seriously his talk is all about the physics of certain type of spacetime singularites-such as the one that live's in our universe's past-and whether life can make sense of the idea of space and time coming into being after sucha singualrity, while not existing prior to that


    I should start off from a quote of Clifford's of Cosmic Variance, becuase of Q's insistance in regards to the descritpions of singularities and my lacking an understanding and somewhat confusion. I thought I would do some more research here.

    There are "certain assumptions" I am making and this is in regard to the a statement Clifford makes, is held as a question in my mind of what exists before anything can emerge into the spacetime? While he has called this beginning "spacetime" and reference "another state" before this, what is it? This is what holds my assumption and idea about what the singularity is doing.

    Lubos Motl:
    We need to get closer to the "theory of everything", regardless of the question whether the destination is a finite or infinite distance away. (And yes, the path should not be infinitely long because there is no physics "below" the Planck length.)


    I place this, too support what Clifford is saying in regards to the what is emergent into the spacetime from what I understand(Strings as a building block on the road too, not as the source of this "emergent property?"). Where do all these dimensional ideas then reside? You can't ignore this, or what Lubos "is saying" about talking about the past? Everytime one's perception changes, the hisory changes too? It forces you to look at the future in a new way?

    Not Newtonian

    It is certainly not the Newtonian version I am thinking about. People tend to think of these as diamonds(?) or something like that as a Pea? I tend away from that thinking, because it just doesn't chive with what is tramsmitted into what "being [is] in spacetime?," if you don't have a foundation from which to work?

    Call them coordinates and in it, the spactime emerges, and from that "okay" the looking at the arrow of time which implies to me a simplier supersymmetrical idea, looking back. So how did you get there? The outside/inside "quandry that stretches the mind capbailites" while chasing the "idea" as Brian Greene's Koan?

    There is something to be said in how "ideas emerge from all the information gathered and accumulated" spontaneousily bursts into a new form? The mind goes through a bit of a change? See's differently. Reinmann accomplishement along with those of the geometrical forbears(shoulder's of giants) help to change how we see geometrics.

    Briefly I pick up the Kurzwelian book on singularities, and find that a greate rperspective is need beyond what is espoused. A new stage in the thinking, beyond what society is thought to be headed. Some reject Kuhnian thinking but this is revolutionary to bme in what an dhow th emind proceeds in bringing down to earh the ideas that await to form in mind. Another place perhaps? A way of dipping the "toe" into the stream, and letting all that "informtaion" flow through you?

    A black hole in astrophysics often has two distinct meanings. The first is the black hole in a general relativistic sense - the extreme gravitational case with a singularity in space-time - while the second is a simpler Newtonian approach: a black hole is just a point mass. While both of these meanings are used, often interchangeably, throughout the literature, it is important to remember that no astrophysical observation has yet been made that can distinguish between the two; to date, the Newtonian point mass is all we need. In the future, with better X-ray observations and a detection of gravitational waves, this may change.



    First off I wrote the post Singularities should be rewritten as "a question" of what I was seeing inregards to our universe. What is in our universe's past. The reason for it's inflation. The reason for entropic valuations that become complicated and end in some chaos reasoning that Sean askes of those to solve in the Three body solution? I think this ahas already been done from what I understood so that push me towards lagragian perspective s and the other assumptions I have about this beginning and what existed before it?

    Here's what I write:

    Plato:
    If the initial states at the beginning of the universe are to be in concert with particle reductionism, and the particle creations that I have exemplified in how particles came into being, then, the understanding of what can be transmitted through the blackhole is extremely important as a valuation of what appears over time?


    So I have to say yes I am quantum characteristically driven to see this universe as it existed in a state held in our perceptions, of what it has become today. So of course I was looking back, with new knowledge of what the futre is to become. Why shouldn't it matter what help to draive this situation in the universe we have to day not hold perspectove abot what has emerged in the spacrtime as we know it?

    Strominger:
    The old version of string theory, pre-1995, had these first two features. It includes quantum mechanics and gravity, but the kinds of things we could calculate were pretty limited. All of a sudden in 1995, we learned how to calculate things when the interactions are strong. Suddenly we understood a lot about the theory. And so figuring out how to compute the entropy of black holes became a really obvious challenge. I, for one, felt it was incumbent upon the theory to give us a solution to the problem of computing the entropy, or it wasn't the right theory. Of course we were all gratified that it did.

    Gold and Fool's Gold

    Gold
    Perhaps the highest density known is reached in neutron star matter (see neutronium). The singularity at the centre of a black hole, according to general relativity, does not have any volume, so its density is undefined.

    The most dense naturally occurring substance on Earth is iridium, at about 22650 kg·m-3.

    A table of densities of various substances:


    So of course seeing this new posting and the ideas of what the gold nugget "is," is supposed to be here in our thinking is of course. Being clarified in terms of how we look at the LHC, most defintiely. Having expert opinion on this is always important. for sure.

    Fool's Gold ?

    Who is not without some blemish on the "heart values" when it had been held to a goal like truth, and had gone astray? It just matters that you try, and that you hold this value in front of your eyes, as you progress through life.

    I was at a loss for what would describe "this beginning" and having looked at what is attained in the "Pascalian triangle", how could I not learn of the spiral induced numbers that lie at the very heart of such creations.

    You have to understand what the basis of what this triangle is based upon. I gave clues here.

    Some fractorial mathematical based idea, exposed to the matters, as crystaline objects of perception unfolding? Wolfram?

    NPR's Richard Harris reports on the beauty of mathematics

    How are some things built, that you would ignore "the mathematics at the basis of experience." Having such a geometrical basis is very important. I may call it "Algebraic equations" of Dirac(Lubos take note:), but it is more then that, and it is in the emergence of strings, that we recognize where the conditions are, as the strings basis? You had to understand "the entropic" as well as the CFT issues from the blackhole state? What are the initial conditions?

    If I say microseconds, you should immediately assume it is after the big bang.:)Topological "geometrics" eh? :) is much different, then what we see classically of the 3+1? You remember "Klein's ordering of the geometries," of course? Right?

    Gold in the Landscape?

    I was looking for a specific posting on "Fool's gold" so I thought of Clifford's at Cosmic Variance and the post he created. A specific comment that I made. No, this does not imply anything against Clifford. :)

    Here you might refer to the points between Lubos and Bee, about the "initial conditions?" It's "beyond" the placement of what is held in microseconds, and the arrow of time. What! Before time began?

    So where is that? What already existed?

    However, don't be fooled! The charm of the golden number tends to attract kooks and the gullible - hence the term "fool's gold". You have to be careful about anything you read about this number. In particular, if you think ancient Greeks ran around in togas philosophizing about the "golden ratio" and calling it "Phi", you're wrong. This number was named Phi after Phidias only in 1914, in a book called _The Curves of Life_ by the artist Theodore Cook. And, it was Cook who first started calling 1.618...the golden ratio. Before him, 0.618... was called the golden ratio! Cook dubbed this number "phi", the lower-case baby brother of Phi.


    What a Cosmologist Wants From String theory by David Wand


    I mean have tried to instill a good foundational perspective of what happens, and what is percieved, in terms of the joining of microsperspective views in regards to the nature of the cosmo?

    So what is not revealled here in "my thinking" although we have been directed to the process of the "collidial views" imparted by expert opinion and further glossed by Q's blog building to face this thinking process? :)




    A debate/dialogue is always a good thing to initiate, and I have not be too lucky to have somebody to run against my thinking. It's a relief Q. As you say, "I am looking for truth."

    So where I am going to go from here? :) Should I go?

    Well science has this thingy about experiment and beyond that, beyond the standard model, what thinking shall I introduce? Something "beyond the 3+1" perhaps? :)

    GRand Quantum Conjecture



    My continued looked into the "fluids dynamics" had me wonder about the superfluid anomalies. How would the "sphere look" if it collapsed and allowed information to travel through it, based on what has been given here for perspective, when the "state of equillibrum" is arrived at?

    In regards to 3, let's just say the assumption is from a theoretcial standpoint, that microstate blackholes "are created." They are created in "cosmic particle collisions" as well?

    This is the premise from which I work, and how I gave "how particles are created," a beginning(dimensional referencing), and a basis from which all science becomes "evidentary" in the particle creations.

    Exotic physics finds black holes could be most 'perfect,' low-viscosity fluidVince Stricherz, University of Washington

    Son and two colleagues used a string theory method called the gauge/gravity duality to determine that a black hole in 10 dimensions -- or the holographic image of a black hole, a quark-gluon plasma, in three spatial dimensions -- behaves as if it has a viscosity near zero, the lowest yet measured.

    It is easy to see the difference in viscosity between a jar of honey or molasses at room temperature and a glass of water. The honey is much thicker and more viscous, and it pours very slowly compared with the water.

    Using string theory as a measuring tool, Son and colleagues Pavlo Kovtun of the University of California, Santa Barbara, and Andrei Starinets of the Perimeter Institute for Theoretical Physics in Waterloo, Ontario, have found that water is 400 times more viscous than black hole fluid having the same number of particles per cubic inch.


    Your points in conclusion,I, II, III

    I-yes
    II-yes
    III- from my conclusions as well.

    Again in above quote, I am defining the leading perspective on blackholes as they are being theoretically defined now, and will be subject to experimentation soon?:)

    Now again "backreaction in the laval nozzle" is up for inspection here as we delve deeper into the nature of the blackhole.

    Nature in Analog Models

    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).


    "Analogistical behaviors" help to push perspective, where before, our theoretical explorations had ran dry?

    Q:
    These wormhole like 'blackholes' do not lead to other pocket universes, unless we choose to call another sector of space a pocket universe, like Europeans first called the land across the Atlantic the 'New World' or Australia 'Another World' yet still clearly part of this World we call Planet Earth.


    If we are to think that the overall context can be apllied to this universe, then such evidence "should be obtainable" as to the nature of such a beginning? But even still, to your point and aspect within this universe, we are looking for accontable methods to such dark energy creation?

    Plato:
    Every picture held in mind is a link to other pictures


    Each event in regards to gravitational collapse would be indicative of what can be "put back into this universe" and sustain it?

    Lubos Motl:
    The mechanism behind sonoluminiscence remains a bit controversial. Claiming that a thermonuclear fusion occurs during sonoluminiscence is among the more conservative explanations. The physicist Claudia Eberlein argued that the correct explanation is that the imploding bubbles create sonic black holes and the flashes are the counterpart of Hawking radiation as the sonic black hole evaporates. You should not think that this is an example of a very, very low energy quantum gravity because the sonic black holes have no connection with the scales of gravity. It is not a supercollider in a glass of beer. But let me admit that as an undergrad, I was excited by this proposal, at least for a few minutes, but I apparently forgot the details of that encounter.


    So by developing this picture of the "bubble collapse in sonofusion", and let's forget about the energy produced from such bubbles and focus on the geometrics of such a collapse. That's my point.

    Lubos Motl:
    Janice Granhardt has pointed out a press release that is two days old and arguably much more serious and potentially far-reaching than the news about "sonofusion" we described yesterday.


    That is part of my conjecture as well as the "unification factor" in my GRand Quantum perceptions.:)That if you remember Kip thorne's plate 27 you will understand that information from the collapse had to be sent over a great distance for us to make sense of the geometrical dynamics that are unfolding from that time and place.

    So you look for the gravitational waves that Webber initiated, and Kip Thorne encouraged in our measures of what is actually being transmitted. Kip Thorne is the father of the LIGO program?

    You must remember gravitational waves have not yet been verified, yet the theory of GR implicitly tells and is about gravity. It was thus taken further in my conclusions having understood that the creation of this infomration would allow one someday "to map" this very collapse in terms of the gravitonic information left in the bulk?

    This is "Dimensional orientated" from a beginning(11dimensional view?), from which evidence is "the 3+1."

    That's outside the box thinking? :)Cosmologists work "inside," as Clifford of Cosmic Variance once said?

    How then is such a gravitational heat generated from the boundary conditions(blackhole), which grows ever smaller in that collapse, and our energy valuations go higher to supersymmetical realizations? The present volume calculated in the extension of our universe would have to be in concert with the volume before such a collapse was to be expected?

    This "total energy value," assuming the universe is flat teeter's on the brink of ?:)

    Total dark energy would have to account for this and supernova events contributing as well as, particle collisions that go on all the time?

    So if space is not really empty, then what is it supposed to be filled with? Quantum harmonic oscillator and zeropoint?

    THEORETICAL MATHEMATICS

    Before I was to ask the question below I had gone through the links given by Alejandro RIvero and in and thinking of the work I had been doing to understand this relation between mathematics and the physics world.

    Of course as you know I am deeply involved in building a "foundational perspective" in a number of ways, which takes up a enormous amount of time. So having these oportunities to advance my thinking, are extremely difficult now, besides putting in a full days work in the heat and misquitos.

    I ask this question on Cosmic Variance for obvious reasons.

    A VIEW OF MATHEMATICS by Alain CONNES

    Most mathematicians adopt a pragmatic attitude and see themselves as the explorers of this mathematical world" whose existence they don't have any wish to question, and whose structure they uncover by a mixture of intuition, not so foreign from poetical desire", and of a great deal of rationality requiring intense periods of concentration.

    Each generation builds a mental picture" of their own understanding of this world and constructs more and more penetrating mental tools to explore previously hidden aspects of that reality.


    After reading here, some things pop into my mind about the work I had gathered from Hooft, on the defintions of "theoretical developement."

    When I read this it seem to bring it together a little more for me.


    String theory clearly appears to be strikingly coherent. What seems to be missing presently, however, is a clear description of the local nature of its underlying physical laws. In all circumstances encountered until now, it has been imperative that external fields, in- and outgoing strings and D-branes are required to obey their respective field equations, or lie on their respective mass shells. Thus, only effects due to external perturbations can be computed when these external perturbations obey equations of motion. To me, this implies that we do not understand what the independent degrees of freedom are, and there seems to be no indication that these can be identified. String theoreticians are right in not allowing themselves to be disturbed by this drawback.


    So you know you are stifled by a problem? You need ways in which to think about this?

    So, in thinking about the mathematics and physics involved, are the two so wide apart that we can say that the world of the "theoretical mathematics" is so far from the reality of the "average human being," that they are to smart for us? Or is it, that they "see" in different ways?

    That is the jest of what I see in Dirac's wordings I highlight or Alain CONNES words for more thinking. It is not enough for me to be dismissed out of hand on "string theory", for what has been experimentally challenged, should be cast aside for, "other roads to quantum gravity," so easy.

    I see something beautiful in it myself, of course, being biased from the "position of speaking" that I do by name only:)

    Responsibiity of course rings very well within my mind, as I write these words. It is not my intention to take people down roads and divert them from the roads that lead them to quantum gravity? But to keep my self critically thinking about the problems that are being spoken by, engaging in, the topic Sean produced in "stringtheory backlash."

    There is some healing that needs to be taken care of, that has been inflicted on those who are speaking, for and against string theory, while it is perspectve "on vision" that must be maintained? The algebraic equations are something I am working on to develope.

    Purpose of the Compton Lecture Series

    April 8The 63rd Compton Lecture Series, 2006 through June 3, 2006, 11:00 a.m.

    Sean at cosmic variance point to this series of lectures that are being presented each year and in this series the entitled is called, "String Theory: With a View Towards Reality" which will be presented by Nicholas Halmagyi, McCormick Fellow, Enrico Fermi Institute.

    Dear Friends of the Enrico Fermi Institute:

    We cordially invite you to join us for the next series of the Arthur H. Compton Lectures. The Lectures are intended for the general public, friends of the Enrico Fermi Institute, members of the University community, and interested citizens of the Chicago area. They provide a descriptive account of some of the frontiers of present-day science. We don’t expect you to have a formal background in mathematics or science, but hope to appeal to your curiosity and to share with you some of the excitement of modern scientific research.

    String Theory is an attempt to describe all particles by multi-dimensional objects, such as strings and membranes. These objects propagate in a ten dimensional universe of which four dimensions are visible to us. This rather outlandish conjecture has led a large community of theoretical physicists to hope for a unification of particle physics and Einstein's general relativity.

    The rather serious caveat is the difficulty in providing predictions which can be experimentally verified since the physical manifestation of the string hypothesis will be most obvious only at energy scales which far exceed our current experiments.

    In these lectures Dr. Nicholas Halmagyi will explain the humble beginnings of String Theory and will detail the staircase of energy scales which climb up to quantum gravity and string theory. No scientific background is required.

    Just bring your curiosity. We hope you can join us for the first lecture on Saturday, April 8, 2006 at 11:00 AM in Room 106 of the Kersten Physics Teaching Center, 5720 South Ellis Avenue. Enter through the door at the southeast corner. The series will run from April 8, 2006 through June 3, 2006.

    There will be NO lecture on Saturday, May 27th and the Compton Lecture Luncheon will be held on June 3rd.

    Sincerely,

    James E. Pilcher Director


    There is a list of Present and Recent Abstracts, some mentioned in the article presented by Sean Carroll, and many others on the Compton lecture presentation itself.

    For me it will be a interesting set of lectures, as I have watched this development for the last couple of years trying to piece togehter the essence of this perspective, about the way in whch one could now percieve a model used to help grow towards a dimensional expression of particle physics in high energy areas.

    I would not like one to think that I am without purpose in my attachments to Cosmic varaince, and to those there in cosmic variance without understanding that some in their respective trades, are just as green(e) when it comes to applying their tools of the trade with string theory, while working their specific areas.

    Also too, having watched a previous writer like Leonard Mlodinow, the quest to pursue science as well as develop the "path with a heart," to me exemplfies the struggle of some science people to find this part of themself. Meanings, to continue in the directions they do. While it might have been a aimless struggle( the recorded history) that apparent at one time as the story unfolds, were the glimpses into other times of people, as the greater teachers of science, like Feynman or Gellman, these insights into their lives present some of the essesnce of what has to be found as motivations needed to develope awareness not only for themself, but in the struggle to move society along with them.

    Nodes and Anti-nodes

    Tool's for measure.

    The center of the gyroscope is a jewel-like sphere of fused quartz. These spheres, the size of Ping-Pong balls, are the roundest objects ever made by man. The tiny spheres are enclosed inside a housing chamber to prevent disruption from sound waves, and chilled to almost absolute zero to prevent their molecular structure from creating a disturbance. The accuracy of these gyroscopes is 30 million times greater than any gyroscope ever built.


    Making Strings in the lab, made me think of Clifford and the ice cream mix that he was privy too, by joining condense matter [ahem...string:] theorists, on a Friday night? :)Nitrogen, and superconductors seem to go hand in hand? Made me think of GPB and [whoops my mistake-not-nobium sphere], were mention for a reason.:)



    Normally I do not like to encourage such a view held to speculations, but the transferance to 3d effective thinking and all that, had me look at WMAP, was a process lead through by valuating sound in such analogies. As a layman, I hope I am forgiven.

    Is it the process?

    Visitors' shadows manipulate and reshape projected images of "Buckyballs." "Buckyball," or a buckminsterfullerene molecule, is a closed cage-structure molecule with a carbon network. "Buckyball" was named for R. Buckminster "Bucky" Fuller (1895-1983), a scientist, philosopher and inventor, best known for creating the geodesic dome.

    Nanomandala:
    The purposeful arrangement of individual atoms bears some resemblance to the methods monks use to laboriously create sand images particle by particle, however, Eastern and Western cultures use these bottom-up building practices with very different perceptions and purposes.

    To me it is a interesting way of seeing what is happening in space held by perception. BUcky balls and such, from my early days of reading BuckminsterFuller and his interesting building concepts, had somehow morphed into dynamical triangulation, used in the monte carlo method of quantum gravity perceptions.

    Dr. Jenny's cymatic images are truly awe-inspiring, not only for their visual beauty in portraying the inherent res-ponsiveness of matter to sound (vibration) but because they inspire a deep re-cognition that we, too, are part and parcel of this same complex and intricate vibrational matrix -- the music of the spheres! These pages illumine the very principles which inspired the ancient Greek philosophers Heraclitus, Pythagoras and Plato, and cosmologists Giordano Bruno and Johannes Kepler.


    Dimensional views of the "quark to quark measure" had me see the dynamics of this distance?

    How much more then would such a weak field describe for us the oscillation of the neutrino, from one phase state to another. One distance to another? A revealled in cosmic rays, as "new physics perhaps" that extends beyond the standard model?



    Paul Dirac

    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.


    If for one moment you continue the thought processes in light of visionary changes sought by and spoken in context of polarization effects in the WMAP, then such views have a profound effect, to what was always interesting data from cosmological apprehensions in discovery.

    Mikheyev-Smirnov-Wolfenstein effect92 April 2006 wikipedia)
    The Mikheyev-Smirnov-Wolfenstein effect is a particle physics process which acts to enhance neutrino oscillations in matter.


    While dynamic functions are being revealled to me of microprocesses( phases states), these dynamics are always interesting from what the geometrical perpecive of what was derived from Dirac.

    A "three dimensional view" of what may be happening in the abstraction of space dynamics seen in UV perspective described in analogy to Gauss's coordinates?

    Something much more profound and detail in a greater depth of thinking of an abstractual nature perhaps? B Field dynamics, would be a interesting comparison while holding mind in geometrical abstraction?

    Antineutrinos From Distant Reactors Simulate the Disappearance of Solar Neutrinos
    The potential importance of the Kamland results goes well beyond the solar-neutrino problem. Particle theorists hope that the masses and flavor compositions of the neutrino mass eigenstates will help point the way to an encompassing unification beyond today's manifestly incomplete standard model of fundamental particles and their interactions. Detailed knowledge of the neutrino states might also elucidate a central problem of cosmology: How did matter come to dominate over antimatter in the immediate aftermath of the Big Bang? Does the mixing of neutrino states harbor the symmetry-breaking mechanism that could have done the trick?


    Oscillating flavorsThe three neutrino mass eigenstates are presumed to be different coherent superpositions of the three flavor eigenstates (ne, nm, and nt) associated with the three charged leptons: the electron, the muon, and the tau. There is good evidence that only two of the three mass eigenstates contribute significantly to ne. In that approximation, one can write



    The question always arises in my mind about the quantum harmonical oscillations, as part of a much larger inherent feature of reality, with which we might view WMAP. Or, events that arise from the sun. Could such analogy, born in the sun's process spit out the nature of the neutrino?

    The plates can be made visible by mounting a mirror behind the row of plates, angled so that the top of the plates are visible to the audience (same idea as in Polarization by Scattering). Create the optimum angle for the front rows, as the back rows will be looking down on the plates anyway. Make sure the cello bow is nice and tactile by treating it with rosin before the performance. Sprinkle the sand on the plates so that it forms an even cover. Don't overdo the amount.

    Have we seen (strange) quark matter?

    Well the very idea that such a thing could exist, has been part of the evolving information I had been going through. To be lead to the understanding, of what new Physics would emerge fromm cosmological and collidial events. That there are indeed showers of particles with which such events will let us know cannot be ignored.

    First Principle needed to recognize "the very state" that things would arise from. For Robert Laughlin, a condense matter theorist, it didn't mater what you called these building blocks, but any discrete measure had to be recognized it's energy value and tragectories would it not? Hence, the particle shower from a known state of existance, where "first principle" would emerged.

    So, any attempt to ignore the possibility of what emerges, and the foundational perspective, put forth in theory, has to help the understandng of what happens when such events do happen, either, micro perspectively or cosmologically.

    Any attempts to say that the standard model is not inclusive in this design, would be detrimental to the very statement any mathematican would say against, that simply erasing any connection, would have been futile to their creditbility?

    Strange Quark Matter TheoryTamas S. Biro

    Ladies and gentlemen, this is going to be the theoretical summary talk of the Strange Quark Matter 2003 conference. When I was alerted by the e-mail we all got, “prepare your transparencies”, I took this home-work exercise seriously. I have prepared quite a few pages before this conference. What can one know in advance, before listening to the talks?.

    First of all there is a general outline which a summary talk should follow. On the level of the basic theory one is supposed to conclude about the present status of the underlying theoretical concepts, one ought to emphasize important news, the novel aspects we are encountering, and finally it is useful to formulate in a possibly definite way, what our perspectives for further development are.


    So given the research that I had been going through, what is this strangelet subject that was developed, and I will post links that support the development of the fear with which such a thing arose. Was answered, by cosmological and collidial production of microstate blackhole events. Might the story and television series of blackholes been interrupted by such a dialogue, or had I furthered the plot for public consumption? To continue the fear?

    Would your scientist/mathematican friend tell you about such things and ways in which to expect information from experimental designs, as not leading into the desire of the essence of new physics?

    What began this assumption, was the idea that microstate blackholes were something of a danger, if we were to created them. That was the nightmare. The reality is, that this theoretically written state, is quite useful in terms of what can emerge from the idea of new physics, and had to include the standard model.

    To get to new physics you had to have the standard model as a basis, and to move from that point, any resulting shower and new information, like in ICECUBE, along with the historiy and research of neutrinos, points to what? Strangelets to what?

    Peter Woit dissassociated himself from that possibility, and if strings was to underly this view, what says, such advancements had not adhered to the demands of theoretcial proposition, that it now sees itself, as part and parcel of the planning for what else will emerge? Sees itself immersed in tachyon demonstration as a sign of cerenkov radiation as that blue light?

    So indeed I struggle with how such theorectical position might have told me what is going on, and this issue, is not to be ignored as long as it is remianing consistant with the developement from standard model presumptions.

    Paul first, and then I had been wondering about this issue right back in the beginning as it came to our attention. Steinberg and clarifications on what the microstate balckhole is was important, as it demonstrates the basis of work being done taking the energies and collidial events, to a new level of reductionistic perception. The microstate blackhole is the basis as far as I can tell.

    Now given the state of Quark Gluon Plasma, what happens when you see such things hhappeniing that you have to aassume a new theoretcial position like M theory that such D Brane assumptions talk abut the viscosity nature? What are the poperties that have emerged from the idea of the blackhole, as this new state of matter tells us something about superfluids and such?

    Does Peter understand these new developments? Does his own theoretical position from model assumption he also used, have correlates to current day information and research? It had been my hope, that his position would have created the dialogue necessary. I have enjoyed the mathematical adventures he has shown has developed further my perspective as shown, in the very last link below.

    In order to have the perspective and vision of the abstract world of the mathematics shown, you needed to know some things. They had to be couched in the history of all that we have learnt, and any modification in mathematical language, alters that perspective, if it relates to the very work you are doing on extending the standard model?

    Nature in Analog Models

    Plato:
    "For everyone, as I think, must see that astronomy compels the soul to look upwards and leads us from this world to another."


    Oh! how complete our world view would be, that I have moved quickly to the very question of all summations given. That while "visually" occupying the mind, we had been taken to the standard model's extension. That we moved beyond, to the "introduction of the graviton," as a force carrier? What world is that Plato?

    Structuralists, like Plato we would be, that we seen not as Feynamn did, but as "platonic developers" as to the very alluring question of, "nature's form?" Lost was our view of the "interactions and processes" yet, seen in another way? That there is a discription ,of all of what these particles could be?

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

    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).


    Part of the theoretics I imagine, is trying to incorporate this into analog models for a deeper comprehension of concepts mathematically embued. Part of the deeper intuitive developement, is what attracted me to the questions about "creativity" and what can be immersed in minds of scientists. What they do with their days.

    Murray Gellman:
    On Plectics
    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.


    As I read Feynman's words about what the scientist actually does, the human side of the scientist makes it very clear to me, that they are to be treated with the respect, as he conveyed his thoughts. As we might, treat someone who brings together "different ideas" to move conceptual understanding forward, much like those in the mathematical ways. Better to be ignored, eh?:)

    Vision Can Move in the Small world

    The Planck scale is the scale at which quantum gravity is believed to become important. At this scale the smooth structure of spacetime breaks down into some structure (strings, spin-foam, lattice, who knows?). The Planck length is approximately 10-35 m, which is very, very small. To get an idea of how tiny this is we can compare a Planck length LPl with the size of a proton and the size of Rhode Island. The radius of a proton is larger than the Planck length by roughly the same factor as the size of Rhode Island to the proton.


    Did we ever comprehend how we would take our "vision" down to a world so small that we did not recognize that occupying the physical world of large things, there would be comparsions needed. That the "particles" that Murray Gellman speculated would emerge from some model, and become the constituents of a world created in the wonder of, "all these particles may be part of the some alternate form of the same thing?" This arose in the 1950's.

    So before, Susskind and Nambu, Gellman held a interesting perspective, and from it, a question arose. It became the developing insight of string theory. Some, have abandoned the very question and idealization, having graduated to Brane world, does not mean, the very thoughts and principals embued in this focus to the small world, would have been discarded, just, that it will have gone through "revisions and progress" in conceptual design?

    Analog models of quantum field theory in curved space

    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.


    Plato as a Composer

    Can a different kind of thinking encase the brain's ability to "envision the abstract of space" to know that it's harmonic values can be seen as the basis of experience?


    Those who would conduct the orchestra, enlisted sounds, which make a whole compositon? One, from which, if physical sight had been remove, and focused internally, had just witnessed the particle world in shower, would lead one to the climatic vision of, "nature of things." From, "it's source?" What began before this whole musical interlude, much as if, the cosmo will wait for our question as to what was?

    So now the very idea of the poem wording I developed here, "no time standing always new", had me thinking about how such a cyclical processes could have ever made its way into our "completeness of views". An extension, beyond the standard model. It was a logical question and place with which responsibility can be still held, regardless, of those who have spelt out the lineage of science in research in this way(string theory model), as some disrupted process in the way of thinking?

    So how would we map this whole process, while we had been taken down to such reductionistic principals. The continuity resorting to structurally discrete, while pondering this structure( what model shall you insert here, Loop, Twistors, Strings)? There are "no rules and no physics" with which we can "initiate thinking" beyond the standard model? So we see the minds very busy with such introductions, professors hired to work the field of choices. Whether to teach or not? To be devoted to a specific area, or just ponder the most difficult question, as to the natures very structure?

    So now we come to a important question, having recognized the power with which the Word "Plato or Aristotle will now be invoked in your mind. That the "archetypes" had been drawn and related. Any future reference, will be in the way Plato might of felt having held his views on music? Possibly, thought about the nature of the world with structure. Developed the forms, as constituents of the way the world exists now.

    More on Dual Nature of Blackhole

    In some theories, microscopic black holes may be produced in particle collisions that occur when very-high-energy cosmic rays hit particles in our atmosphere. These mini-black-holes would decay into ordinary particles in a tiny fraction of a second and would be very difficult to observe in our atmosphere.

    The ATLAS Experiment offers the exciting possibility to study them in the lab (if they exist). The simulated collision event shown is viewed along the beampipe. The event is one in which a mini-black-hole was produced in the collision of two protons (not shown). The mini-black-hole decayed immediately into many particles. The colors of the tracks show different types of particles emerging from the collision (at the center).



    The RHIC fireball as a dual black hole
    We argue that the fireball observed at RHIC is (the analog of) a dual black hole. In previous works, we have argued that the large $s$ behaviour of the total QCD cross section is due to production of dual black holes, and that in the QCD effective field theory it corresponds to a nonlinear soliton of the pion field. Now we argue that the RHIC fireball is this soliton. We calculate the soliton (black hole) temperature, and get $T=4a /\pi$, with $a$ a nonperturbative constant. For $a=1$, we get $175.76 MeV$, compared to the experimental value of the fireball ``freeze-out'' of about $176 MeV$. The observed $\eta/ s$ for the fireball is close to the dual value of $1/4\pi$. The ``Color Glass Condensate'' (CGC) state at the core of the fireball is the pion field soliton, dual to the interior of the black hole. The main interaction between particles in the CGC is a Coulomb potential, due to short range pion exchange, dual to gravitational interaction inside the black hole, deconfining quarks and gluons. Thus RHIC is in a certain sense a string theory testing machine, analyzing the formation and decay of dual black holes, and giving information about the black hole interior.



    The case for mini black holes
    Geodesics in Kerr space-time, as predicted by the theory of general relativity. Small black holes produced, for example at colliders, are expected to be spinning. Image: Numerical simulation by Max Planck Institute for Gravitational Physics, Albert Einstein Institute (AEI); visualization by W Benger, Zuse Institute, Berlin/AEI

    Approaches of the Gauss-Bonnet type, which include quadratic terms in scalar curvature in the Lagrangian, are good candidates for a description beyond general relativity as they can be supported both by theoretical arguments (heterotic strings in particular) and by phenomenological arguments (Taylor expansion in curvature). In such a case, the coupling constant of the Gauss-Bonnet term, namely the quantum character of the gravitational theory used (and the link with the underlying string theory) can also be reconstructed and the LHC would become a very valuable tool for studying speculative gravitation models.

    Other promising avenues are also being investigated for new physics. Firstly, the black holes formed may be excellent intermediate states for highlighting new particles. When the collision energy is higher than the Planck scale ED, the cross-section for the creation of black holes is quite large (~500 pbarn) and has no suppression factor. Moreover, when the temperature of the black hole is higher than the mass of a particle, the particle must be emitted during evaporation in proportion to its number of internal degrees of freedom. There is thus a definite potential for the search for the Higgs or for supersymmetric particles in the evaporation products of black holes, possibly with cross-sections much greater than for the direct processes. Finally, taking account of a D-dimensional cosmological constant also modifies the evaporation law. If the constant is sufficiently high - which is possible without contradicting the low value measured in our brane - the temperature and the coupling coefficients with the entities emitted could be the signature of this particular structure of space-time. It would be quite neat and certainly surprising that a measurement of the cosmological constant in the bulk should come from the LHC!

    Microscopic black holes are thus a paradigm for convergence. At the intersection of astrophysics and particle physics, cosmology and field theory, quantum mechanics and general relativity, they open up new fields of investigation and could constitute an invaluable pathway towards the joint study of gravitation and high-energy physics. Their possible absence already provides much information about the early universe; their detection would constitute a major advance. The potential existence of extra dimensions opens up new avenues for the production of black holes in colliders, which would become, de facto, even more fascinating tools for penetrating the mysteries of the fundamental structure of nature


    Public Service Announcement: Black Holes @ RHIC by John Steinberg

    Unfortunately, all of this is overstated. At RHIC we don’t make a “real” black hole, in the sense envisioned by Einstein’s General Theory of Relativity. Rather, Nastase’s point of view is that RHIC collisions can be described by a “dual” black hole. But what does “dual” mean in this context? It’s not “two-ness” in any sense, but rather indicates that one can write down a theory which describes the collision as a black hole, but in a completely different world than that we see around us. To make his model work, he (and many other researchers who are exploring this direction) make a calculation of a black hole in 10 dimensions in order to describe difficult (but gravitationally benign) aspects of the strong interaction in 4 dimensions.


    No Black Holes Today, Thanks

    As George Musser remarked to me in an email,

    Egads, what a mispresented story. Nastase says they might be *dual* to black holes -- a relation of interest in string theory, but hardly the same thing as an honest-to-god black hole.

    Exactly. The point of Nastase's paper is not that the RHIC fireball may be a black hole but that it might be described by the same math used for black holes. Such duality is vital in modern physics, because some problems are easier to formulate and solve within one mathematical framework rather than another, although both are applicable.

    Now, if you want to know about the real prospects for making microscopic black holes by colliding particles in an accelerator, watch for the May issue of Scientific American, which will, by happy coincidence, have a feature on that very subject.

    Intersection of D Branes

    I'm not going to try and kid you with "this stuff," as it is extremely beyond anything that any of us mere mortal can understand. So, if such a thought would be to simplify, then how would such thinking be attributed to such model building and make it easier for us lay people to comprehend where these people are working in terms of the way they do things.

    What is important is that we can derive some method to this madness:) okay! rather this abstract thinking, to show some kind of similarity in lay people's current thought patterns for easy recognition.

    I'll burn in hell, if I get this wrong, but surely from my "faulty trails (not Tower)" I can be forgiven, until a clearer picture is given to us, that I could revamp all that I said, and leave for you now, the trials and tibulation of a rogue what?:)

    Now you have to think about what I am saying, if you understand indeed, that such a place exists in the picture below, which for us mortals to consider. Think for a minute about the blackhole and where I had been talking in relation to the collider, as well as, the cosmic collisions taking place, with higher energy particles in our own atmosphere.

    Weak field manifestation has particle consideration evident, and we find these here on earth, as neutrinos. Do You see now?

    Physicists Andrew Strominger and Cumrin Vafa, showed that this exact entropy formula can be derived microscopically (including the factor of 1/4) by counting the degeneracy of quantum states of configurations of strings and D-branes which correspond to black holes in string theory. This is compelling evidence that D-branes can provide a short distance weak coupling description of certain black holes! For example, the class of black holes studied by Strominger and Vafa are described by 5-branes, 1-branes and open strings traveling down the 1-brane all wrapped on a 5-dimensional torus, which gives an effective one dimensional object -- a black hole.


    I thought this to be part of the trivial effort with which I had departed to the bulk perspective, without really undertanding how I had got there. Yet I do see in these ways and many things are encompassed within it(gravitonic concentration). I would say, like Clifford telling us about the proper way in which we should move within these mathematical environs, then I would say what a rogue scholar I make, becuase this seems be the bastard child I am whose school is by insight developement, and some of it, wrong of course. But I try.

    Superstrings, black holes and gauge theories


    D-branes are non-perturbative excitations of string theory on which open strings can end. Open strings have gauge fields, so the D-branes define a gauge theory. There is a class of black hole made of D-branes, and these have a quantum gauge theory description. The closed strings define a field theory of gravity.



    PROSPECTS FROM STRINGS AND BRANESA.SEVRIN

    Strings occur in two versions: closed and open strings. Roughly speaking, one has that closed strings carry the gravitational interaction and the open strings carry the gauge interactions. While closed strings can freely propagate in space, the modern point of view is that the end points of open strings are “stuck” on p-dimensional hypersurfaces, where p ∈ {1, 2, · · · , 9}. These hypersurfaces are known as Dp-branes. They are dynamical but they are extremely heavy in the perturbative regime of string theory (their tension or energy per unit of volume is inversely proportional to the string coupling constant): they are solitons. A D0-brane is a point-like object, a D1-brane a string-like object, a D2-brane a membrane, ... Just as a propagating point particle sweeps out a curve – the world-line – in space-time, a Dp-brane sweeps out a p + 1-dimensional volume – the world-volume – in the 10-dimensional space-time. The effective dynamics on the world-volume is then described by a p + 1-dimensional field theory.





    D-branes represent a key theoretical tool in the understanding of strongly coupled superstring theory and M-theory. They have led to many striking discoveries, including the precise microphysics underlying the thermodynamic behaviour of certain black holes, and remarkable holographic dualities between large-N gauge theories and gravity. This book provides a self-contained introduction to the technology of D-branes, presenting the recent developments and ideas in a pedagogical manner. It is suitable for use as a textbook in graduate courses on modern string theory and theoretical particle physics, and will also be an indispensable reference for seasoned practitioners. The introductory material is developed by first starting with the main features of string theory needed to get rapidly to grips with D-branes, uncovering further aspects while actually working with D-branes. Many advanced applications are covered, with discussions of open problems which could form the basis for new avenues of research

    Following is a collection of lecture notes on D-branes, which may be used by the reader as preparation for applications to modern research applications such as: the AdS/CFT and other gauge theory/geometry correspondences, Matrix Theory and stringy non-commutative geometry, etc. In attempting to be reasonably self-contained, the notes start from classical point-particles and develop the subject logically (but selectively) through classical strings, quantisation, D-branes, supergravity, superstrings, string duality, including many detailed applications. Selected focus topics feature D-branes as probes of both spacetime and gauge geometry, highlighting the role of world-volume curvature and gauge couplings, with some non-Abelian cases. Other advanced topics which are discussed are the (presently) novel tools of research such as fractional branes, the enhancon mechanism, D(ielectric)-branes and the emergence of the fuzzy/non-commutative sphere.

    The Lowest Octave State

    Sometimes simple concepts, like something representing the lowest vibration mode of the string, the lowest octave helps in a sense helps to orientate what the particles mean, such as protons,neutrons and electrons. Where they exist now as they cosmic collsions meet and dissapte it's influence in our atmospheres, our planet.

    Yet Moshe speaking about sparticles has interesting relations in context of symmetry breaking, yet, without thinking about what experiments are now being listed, what value this lowest vibration mode? What value that leads us to think about this lower scale as evidence now held within our views.

    Clifford:
    We’ve got to remember what we assumed in order to get to the cirtical dimensions, and then revisit those assumptions every time we learn something new about the whole story


    Would be a consistent pattern, when new options and experimental consideration are introduced. In the case I listed above in ICECUBE.

    The relative 'up' and 'down' rates provide evidence for distortions in neutrino properties that are predicted by new theories."


    I think this would be consistent on the level of what you are saying Clifford? Lay people like myself would understand this I think. While very aware of the higher energy considerations in context of reductionism, had taken us too dual blackhole considerations within the collisions taking place not just in the colliders.

    It presented opportunites in how we see what strings might have emplied in Cerenkov radiation? What is it that we should see in this relation, that strings would have said here is another opportunity?

    Cerenkov Radiation and the Blue Glow

    At full power (200 kilowatts), the UMR Reactor core produces approximately 6.4 trillion fissions per second. Each fission event liberates a tremendous amount of energy, a portion of which is carried away by fission products which then decay and produce high-energy beta particles. Often, these beta particles are emitted with such high kinetic energies that their velocities exceed the speed of light (3.0x108 meters per second) in water. When this occurs, photons, seen to the eye as blue light, are emitted and the reactor core "glows" blue.

    While no particle can exceed the speed of light in a vacuum, it is possible for particles to travel faster than light in certain mediums, such as water. The speed of light in a particular medium, v, is related to the speed of light in a vacuum, c, by the index of refraction, n, by v = c/n. Water has an index of refraction of 1.3, thus the speed of light in water is 2.3x108 meters per second. Therefore, beta particles with kinetic energies of 0.26 MeV travel at speeds in excess of 230 million m/s!


    It is important to remember somethings here. I am trying to hone in on the exact reasons for this idealization, to see in the ways that we do. Why the sky is blue in relation to the sun that shines and the Earth as it is ?:) How often has the child asked, while we had been witness to the very thing in our everyday waking lives.

    Thus we are quickly transported into the strange world of refractve indexes and such, as examples of what angle and departures these particle might take in their collisions courses. Yet we know as we look up that beyond the blue, it gets dark again Redshifting on the horizons as our sun sets.

    Cosmological particles exsit that are free of our atmosphere. What say these things in that environ, while it is dark? What shall we say of these things when the sun influences dances on our outer atmosphere?

    Wikipedia and the Uses of Cerenkov Radiation(8 Feb 2006)

    When a high-energy cosmic ray interacts with the Earth's atmosphere, it may produce an electron-positron pair with enormous velocities. The Cherenkov radiation from these charged particles is used to determine the source and intensity of the cosmic ray, which is used for example in the Imaging Atmospheric Cherenkov Technique (IACT), by experiments such as H.E.S.S. and MAGIC. Similar methods are used in very large neutrino detectors, such as the Super-Kamiokande.


    So I am again drawn back to the state of the earth's gravitational field, with which this planet being weak, lets us see particle states that it does? How shall I keep in mind, that such circumstance free of refractive indexes( a vacuum)speed of light wil mett the chance to have faster then light capabilties, in a blue glow? Have I then nailed the reasons why such concepetualization take to the two extrmes of what vison had garnered for us, and the circles meaningwhile it signfied this interchangeability?

    Ah, my more layman head. :)Like a Koan supplied to tax the mind, a simple statement is drawn out, over and over again, while in time, the mind becomes flooded with so many possibilities with a flash of light. What is this Koan, that I speak of?

    Brian Greene:
    How can a six-foot tall human being 'fit' inside such an unbelievably microscopic universe? How can a speck of a universe be physically identical to the great expanse we view in the heavens above


    Don't worry Clifford, while Brian Greene might have been the spokesperson for all scientist actors, it is still with some benefit that we undertand how the abstract mind releases itself, but for a short time. While the influence of nature has its way with us. Whilst we had been so intensely looking, the break from the work, allowed the culmination to seep through in a simple jesture of understanding. That seems to be the way of it.
