What Comes Next?

What Lies Beneath, by Eugene Samuel

Likewise, if the very fabric of the Universe is in a quantum-critical state, then the "stuff" that underlies reality is totally irrelevant-it could be anything, says Laughlin. Even if the string theorists show that strings can give rise to the matter and natural laws we know, they won't have proved that strings are the answer-merely one of the infinite number of possible answers. It could as well be pool balls or Lego bricks or drunk sergeant majors.


You might as well famiiarize yourself with Robert Laughlin's, "Self Organization of Matter."

I mean if you think of micro-seconds and someone saids to you, it just doesn't make sense( what energy scale the model of strings applied?) then one might have trouble accepting the report on colliders for consideration, and how we view the outcome of the universe from that beginning?

Nice moose picture in there to look at.

Cycle of Birth, Life, and Death-Origin, Indentity, and Destiny by Gabriele Veneziano

Was the big bang really the beginning of time? Or did the universe exist before then? Such a question seemed almost blasphemous only a decade ago. Most cosmologists insisted that it simply made no sense - that to contemplate a time before the big bang was like asking for directions to a place north of the North Pole. But developments in theoretical physics, especially the rise of string theory, have changed their perspective. The pre-bang universe has become the latest frontier of cosmology


Maybe we need a adustment on what we actually thought happenned at the very beginning? Current science writing then needs to reflect what the information is leading us too?

Quark Soup(Scientific American), is limited then, in what we may think about what happens in those gold ion collisions. The relations, as to what happened cosmologically at the very beginning?

What are the characteristics of superfluids that we would find the work of Ketterle involved here?

Berkeley Lab Technology Dramatically Speeds Up Searches of Large DatabasesJon Bashor

In the world of physics, one of the most elusive events is the creation and detection of “quark-gluon plasma,” the theorized atomic outcome of the “Big Bang” which could provide insight into the origins of the universe. By using experiments that involve millions of particle collisions, researchers hope to find unambiguous evidence of quark-gluon plasma.


Shouldn't that writing lead us to ponder in our minds the next step?

A conclusion then about the difficulties upon which thoughts of viscosity with regards to the beginning of that time? The most perfect fluid. A Hydrodynamical calculation then? I am also thinking of the laval nozzle and the back reaction as well.

You have to forgive me here because it is of some interest that I would like to write, but I would like also to write reasonably and responsibly as well. :)

Cosmic Variance's Very Own: Strangelets in 10 or 11

Cosmic Variance's very own.

Hewett, Lillie and Rizzo found that if so called micro-black holes, which are smaller than the nucleus of an atom, exist, they can be used to determine the number of extra dimensions. If scientists were to smash two high energy protons together they could theoretically make such a micro-black hole. Such a collision could happen at CERN’s Large Hadron Collider (LHC), which will become operational next year. Once created, the micro-black hole decays quickly and emits over a dozen different kinds of particles such as electrons, neutrinos and photons, which are easy to detect. Using the predicted decay properties of the black hole into neutrinos, Hewett, Lillie and Rizzo solved complex equations to determine if our universe has 10, 11, or more dimensions — perhaps too many dimensions to be explained by critical string theory.


So what is the experiment that is being produced?

Using the predicted decay properties of the black hole into neutrinos,

While I consider the state itself, the thoughts of ICECUBE come to mind. This previous ICECUBE post on this is extremely helpful.

What is also helpful is to remember what the collision process produces and how we can see this process in relation to cosmic collisions. Not just in the colliders themself. While we might of debated the strange matter below, I enlist the idea of the gravitonc considerations and maybe it is not altogether clear, it is with some satisfaction that such thinking of dimensional attributes are actually given parameters with which to work?

Strange Matter (12 Feb 2006)

Some theories suggest that strange matter, unlike neutronium, may be stable outside of the intense pressure that produced it; if this is so, then small substellar pieces of strange stars (sometimes called strangelets) may exist in space in a wide range of sizes all the way down to atomic scales. There is some concern that ordinary matter, upon contacting a strangelet, would be compressed into additional strange matter by its gravity; strangelets would therefore be able to "eat" any ordinary matter they came into contact with, such as planets or stars. This possibility is not considered likely, however.

Strangelets are thought to have a net positive charge, which is neutralized by the presence of degenerate electrons extending slightly beyond the edge of the strangelet, a kind of electron "atmosphere." If a normal matter atomic nucleus encounters a strangelet, it will approach until it begins penetrating this negatively charged atmosphere. At that point it will start to see the positive electrical potential and be repelled from the strangelet. Sufficiently energetic nuclei, or neutrons (which are unaffected by electrical charges), can reach the strangelet and be absorbed; the up/down/strange quark ratio would then readjust by beta decay.

Exotic physics finds black holes could be most 'perfect,' low-viscosity fluid

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.

    Cosmic Rays Collisions and Strangelets Produced?


    I like to think of
    Enlightenment in another way Jaffe:)

    While we had focused our attention on the airs about the earth, how would it been possible for us earthlings to push back the limitations on on our views that we could have seen cosmological data in context of all that we do in the environment?

    See QuarkStars on this.

    The collisions are strange: PHENIX can identify particles that contain strange quarks, which are interesting since strange quarks are not present in the original nuclei so they all must be produced. It is expected that a Quark-Gluon Plasma will produce a large amount of strange quarks. In particular, PHENIX has measured lambda particles. There are more lambda particles seen than expected.



    I thought I would go over existing post I made in April of 2005 (se revised version below)and correct some of the links that would be more appropriate to information released in the Blogs of Reference Frame, Cosmic Variance and Not Even Wrong's site about "Amanda and ICECUBE."

    Exotic physics finds black holes could be most 'perfect,' low-viscosity fluid

    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.


    These characteristics of superfluids are very interesting things to consider, as well as what is prodcuerd in "this action" as we are taken to the supefluid created. Think indeed, that this blackhole "is" the superfluid, and the strangelets, what are these? These never existed, until the superfluid was created?

    But in the 10 dimensions of string theory, the fluid of a black hole isn't like other fluids. Space-time is considered to be flat in our perception, Son said, and five of the extra dimensions are compacted into a small, finite sphere. In the remaining dimension, however, space is curved. Evaporation doesn't occur in this dimension, he said, because as particles radiate from the fluid they strike the curved edge of the dimension and are sent bouncing back into the black hole.



    These links help set up the thinking for information outside of LHC, that was given for perspective back earlier by John Ellis. The leading perspective on Microstate blackhole production was given then as well in the post with Quark Gluon perspectives, about strangelets produced.

    While I had thought these relevant to Dark energy creation in our Cosmo, I did not point directly to the nature of these strangelets gathering at the center of our planet. You had to follow all these posts in order to understand the effect of microstate production, not only in RHIC or LHC, but in the cosmic perspective gained from Pierre Auger experiments as well.

    I gave early history consideration so that you might understand a early concern of what mankind might have garnered in thinking, when in actuallity, this was happening naturally every time the cosmic rays penetrated the airs around the earth.

    You might well see now that these considerations have been logically followed and there has not been much help as I had been laying the ground work for how perspective is garnered about gravitational considerations. These though are quickly dissipating blackholes created in the airs, around this planet.


    Cosmic rays are nuclei and elementary particles always falling very fast on the earth from the universe. Enormous number of cosmic rays are always passing through our bodies. Cosmic rays was discovered by Victor Hess, who is an Austrian physicist, on 1912. He went up to the high altitude of 4000 meters by a balloon and found the ionization rate of the atmosphere is raised at the higher altitude by cosmic rays. After that, cosmic rays have been studied extensively and progressively, and mysteries in the Universe and the Nature are being revealed.

    Cosmic rays come from the neighborhood of the Earth and also far galaxies. Galactic and extra galactic cosmic rays are considered to be accelerated at dynamical astronomical objects, such as supernova remnants, neutron stars,and active galactic nuclei. After far-reaching long traveling, they plunge into the atmosphere and bring about nuclear interactions with nuclei of oxygen and nitrogen in the air. The extraterrestrial cosmic rays which come from outside the earth are conventionally called primary cosmic rays, and newly produced particles via the nuclear interactions are called secondary cosmic rays. The main components of the secondary cosmic rays are muon, neutrino, electron, gamma ray, and neutron. While electrons and gamma rays are absorbed into the air, muons and neutrinos can be observed even under the ground.


    Of course, this could all be speculation and misconceptions garnered in wrong thinking. So I'll leave it to the experts to correct the disemmination that would affront theoretical positions and hopefully I'll see such corrections. :)

    Update: Bloggery updating does not seem to be working, so I will recreate the post here for examination.

    4/16/2005

    Cosmic ray experiments must overcome tremendous obstacles. The flux of particles above 1019 eV is extremely low (about 0.5 km-2yr-1sr-1), so detectors need to probe a large effective area to detect sufficient flux. This requires earthbound observatories. Consequently, the high energy particle is detected indirectly, as cosmic ray primaries entering the Earth's atmosphere interact with atmospheric nuclei to produce large cascades of relativistic secondary particles known as extensive air showers.



    It somehow seems appropriate, that having been given some hint fom John Ellis of his research and interests, that the historical record could some how be brought into view. The appearnce of these references enhance later log entries on this site. A sort of moving backwards to get to the esence of what has happened in astrophysics and the journey tounderstand the nergies involved that speak to the idea of particle shower creation that had been consistent with reductionistics view we have gone through in the research of string theory.


    The highest energy particle ever observed was detected by the Fly's Eye in 1991. With an energy of 3.5 x 1020eV (or 56J), the particle, probably a proton or a light nucleus, had 108 times more energy than particles produced in the largest earth-bound accelerators. The origin of the particle is unknown. At such a high energy, and with its assumed charge, the path of this particle through the cosmos would have been relatively unaffected by galactic and intergalactic magnetic fields. Yet no plausible astrophysical source is known along the arrival direction, within the maximum possible source distance imposed by collisions with photons of the cosmic microwave background. This event remains a mystery! It is clear that it existed, but there is no obvious explanation for its source.


    These are some of the links that follow the early hisotry of our observations, so that we underrstand well that such cosmic rays are still viable arena for the understanding of these interactions. Sean Carroll may create the April's fool joke on mass migration from particle reductionistionism to astrophycics, but the truth is what is learnt is very applicable to both arenas and what had been learnt, can never be forgotten as we move our observations to the FLY'EYE

  • Pierre Auger Observatory


  • Cosmological and Microstate Blackholes


  • Early history developement is sometimes important to understand the trends that intermingle began in branches of High Energy Particle Research and Cosmic particle research. We understood well the limitation that we would run into for the size of the coliders necessary for such observations that having understod the limits reached in this regard we see where one branch will push us to consider the world around us and the inertactions developing towards the understanding of thes ecosmic showers that we are experiencing.


    Extremely energetic cosmic rays interact with the cosmic background photons via pair creation and photopion production and lose their energies during their trip. Therefore there is upper limit of distances which they can propagete in the space with a given energy. The above figure shows this limit (so called attenuation length) in case of cosmic ray protons. You see the 2x10^20 eV particles cannot propagate longer than 30 Mpc (100 million light years), which sets the limit concerning the location of possible sources.

    The Blackhole as a Superfluid: It's Viscosity

    Now you must understand that thinking of any first principle is hard to refrain from, especially, if one had thought like I do, that the geometrical tendencies are inherent in the way this is handled, and that it leads to other things? "The equations of relativity fail, and new laws emerge." saids George Musser. " A quark-gluon plasma, in three spatial dimensions - behaves as if it has a viscosity near zero, the lowest yet measured."

    That's important, is it not from a geometrical perspective, because from this Dirac's visionary quest might have said, that here lies the opportunity for such a notion to begin, hyperbolically, or spherically. One way, or the other??

    Blackhole substances are perhaps the most-perfect fluids in existence because they have ultra-low viscosity.
    No matter what you call it, though, that substance and others similar to it could be the most-perfect fluids in existence because they have ultra-low viscosity, or resistance to flow, said Dam Thanh Son, an associate physics professor in the Institute for Nuclear Theory at the 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.


    Lubos Motl:
    The quark picture is more ordinary and materialistic but the black hole picture with an extra dimension is actually more useful to understand some general laws, such as the bounds on viscosity.


    The problem might have been missed, with what one might, or should have look at? Herein the condense matter specialist might have thought hey, a superfluid indeed, and we have created a blackhole of a kind? What is this Bound Viscosity?

    Sungho Hong on December 6, 2003 :
    There is an interesting proposal by Andreas Karch. With certain assumtions, he showed that the entropy bound implies the viscosity bound. Moreover, this relation seems true even beyond the assumptions that he made. An interesting point is that the tabletop experiments could test this. The viscosity of superfluid He4 misses the bound only by a factor of 10.


    Thse ideas that begin to manifest, have been from venturing into ideas of expeirmentation. What had arisen from blackholes in our colliders?

    Frozen Stars
    Black holes may not be bottomless pits after all
    By George Musser July 2003

    Under the right conditions, a fluid can turn into a superfluid, governed by quantum mechanics even on macroscopic scales. Chapline, along with physicists Evan Hohlfeld, Robert B. Laughlin and David I. Santiago of Stanford University, has proposed that a similar process happens at event horizons. The equations of relativity fail, and new laws emerge. "If one thinks of spacetime as a superfluid, then it is very natural that in fact something physical does happen at the event horizon--that is, the classical event horizon is replaced by a quantum phase transition," Chapline says.


    So you don't lose sleep, or the world is a nice place, la te da... because it is what it is?:) It's just a generalization, as any assumption of the data might have convinced one, either way? What is it's value?

    One might have assume because of the time involved, that accumulation and gatherings, might have taken up residence at the center of the earth. So? Okay? :)

    Acoustic Hawking Radiation

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

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


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

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

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


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

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

    Overlap of "quantum" and "classical" behaviour

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


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


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


    Thorne: Black holes and time warps…, chapter 11, "What is reality?"

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


    What is a Phonon/Photon?

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


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




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

    Granularity of the Fluid?

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

    Parallel lines to spherical and hyperbolic functions


    Like different musical instruments, different types of stars produce different types of sound waves. Small stars produce a sound with a higher pitch than bigger stars, just like the 'piccolo' produces a higher sound than the cello


    Did one ever figure out the value of the pitch? So you see, the universe is a concert as well:) You remember Pascal's triangle? The probabilistic valuation asined to the marble drop? Well I created another triangle, but it is a little different model, and does not use numbers for mathematic discretion as a emergent property of first principal. Although mine is distinctive of these characteristics the universe is being applied in sound relation.

    An equation means nothing to me unless it expresses a thought of God.
    Srinivasa Ramanujan

    The most rarified of the matter is a "energy relation in sound", while at the base of this pyramid, all the myriad forms of matter in expression.


    Artists such as M. C. Escher have become fascinated with the Poincaré model of hyperbolic geometry and he composed a series of "Circle Limit" illustrations of a hyperbolic universe. In Figure 17.a he uses the backbones of the flying fish as "straight lines", being segments of circles orthogonal to his fundamental circle. In Figure 17.b he does the same with angels and devils. Besides artists and astronomers, many scholars have been shaken by non-Euclidean geometry. Euclidean geometry had been so universally accepted as an eternal and absolute truth that scholars believed they could also find absolute standards in human behavior, in law, ethics, government and economics. The discovery of non-Euclidean geometry shocked them into understanding their error in expecting to determine the "perfect state" by reasoning alone.


    Sometimes it is good take this idea of sound as a analogy like fluid dynamics so that you can see how far one can be lead to non-eucildean views, and ideas of resonant points that are localized, yet, recognizing the quantum view here, would be a dynamcial one and as fluid? Putting reverberations aside, and discrete measures, think how such blurring could take on new meaning here in uncertainty?



    By studing the early inclinations of people who have this affinity to "sound" how can one not be intrigued by what is to follow after, in the generalizations of mathematcial minds and physicists who are struggling to measure those same gravity waves?

    In the late 1950s, Weber became intrigued by the relationship between gravitational theory and laboratory experiments. His book, General Relativity and Gravitational Radiation, was published in 1961, and his paper describing how to build a gravitational wave detector first appeared in 1969. Weber's first detector consisted of a freely suspended aluminium cylinder weighing a few tonnes. In the late 1960s and early 1970s, Weber announced that he had recorded simultaneous oscillations in detectors 1000 km apart, waves he believed originated from an astrophysical event. Many physicists were sceptical about the results, but these early experiments initiated research into gravitational waves that is still ongoing. Current gravitational wave experiments, such as the Laser Interferometer Gravitational Wave Observatory (LIGO) and Laser Interferometer Space Antenna (LISA), are descendants of Weber's original work.



    Athena:
    The angle of the strikes in relation to the sides of the triangle would be the same as well, delivering similar tones. With other triangle types, depending on the lengths of the sides and the angles, you may have to adjust for the differences while you were playing if you didn’t want those effects.


    While one might think of the triangle of consideration, it would not be to hard to figure that architectural features would have also harnessed? Similar respective examples of solutions from angled to parallel lines, leads to hyperspherical "inner" solutions of the dome, as a consequence of dimensional shape exploitation?:)


    Bernhard Riemann once claimed:
    "The value of non-Euclidean geometry lies in its ability to liberate us from preconceived ideas in preparation for the time when exploration of physical laws might demand some geometry other than the Euclidean."


    So how would they overcome this commanding voice and spread out what is focused? A saucer?

    An Acoustical Nightmare

    "According to one parishioner, the echoes were so bad under the egg-shaped done of Oklahoma City's First Christian Church of Tomorrow that when the minister spoke it sounded 'as though God were repeating every word he said, only much louder." In the hope of deflecting the echoes, a 20-ft saucer was hung from the apex, but it had no effect. An acoustician finally solved the ploblem by overpowering the echoes with an amplifying system. Carefully filtered sound now come from the round speakers on the walls and spreads evenly-and without echoes-over the congregation." Time-Life, Sound and Hearing, p189.

    While seeking to provide good journalism and link to hyperphysics I wanted to extend this to a image. It is unfortunate this could not be done. So, you are left with the source for consideration and perspective. I thought it fitting to the struggles of "sound production" and your "tone variation" on the triangle's length and angle being hit.



    So let's say Michelango sought to send God's "word" to some mortal human like Adam for consideration in the garden? Would he have done it in the way a artist might see such features of sounds reduced to the "chorus of shape" foculizing this power in mortal man? It had to be a thunderous approach? NOn! Oui

    Projective Geometries

    Action at a Distance

    Now ths statement might seem counterproductive to the ideas of projective geometry but please bear with me.


    In physics, action at a distance is the interaction of two objects which are separated in space with no known mediator of the interaction. This term was used most often with early theories of gravity and electromagnetism to describe how an object could "know" the mass (in the case of gravity) or charge (in electromagnetism) of another distant object.

    According to Albert Einstein's theory of special relativity, instantaneous action-at-a-distance was seen to violate the relativistic upper limit on speed of propagation of information. If one of the interacting objects were suddenly displaced from its position, the other object would feel its influence instantaneously, meaning information had been transmitted faster than the speed of light.


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

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

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



    One of the first indications to me came as I looked at the history in regards to Klein's Ordering of Geometries. Now I must admit as a layman I am very green at this understanding but having jumped ahead in terms of the physics involved, its seems things have been formulating in my head, all the while, this underatnding in terms of this "order" has been lacking.

    In Euclidean geometry, the basic notions are distances and angles. The transformations that preserve distances and angles are precisely the rigid motions. Effectively, Klein's idea is to reverse this argument, take the group of rigid motions as the basic object, and deduce the geometry. So a legitimate geometric concept, in Euclidean geometry, is anything that remains unchanged after a rigid motion. Right-angled triangle, for example, is such a concept; but horizontal is not, because lines can be tilted by rigid motions. Euclid's obsession with congruent triangles as a method of proof now becomes transparent, for triangles are congruent precisely when one can be placed on top of the other by a rigid motion. Euclid used them to play the same role as the transformations favored by Klein.

    In projective geometry, the permitted transformations are projections. Projections don't preserve distances, so distances are not a valid conception projective geometry. Elliptical is, however, because any projection of an ellipse is another ellipse.


    So spelt out here is one way in which this progression becomes embedded within this hisotry of geometry, while advancing in relation to this association I was somewhat lifted to question about Spooky action at a distance. WEll if such projective phase was ever considered then how would distance be irrelevant(this sets up the idea then of probabilistic pathways and Yong's expeirment)? There had to be some mechanism already there tht had not been considered? Well indeed GHZ entanglement issues are really alive now and such communication networks already in the making. this connection raised somewhat of a issue with me until I saw the the phrase of Penrose, about a "New Quantum View"? Okay we know these things work very well why would we need such a statement, so I had better give the frame that help orientate my perspective and lead to the undertanding of spin.



    Now anywhere along the line anyone can stop such erudication, so that these ideas that I am espousing do not mislead. It's basis is a geometry and why this is important is the "hidden part of dirac's mathematics" that visionization was excelled too. It is strange that he would not reveal these things, all the while building our understanding of the quantum mechanical nature of reality. Along side of and leading indications of GR, why would not similar methods be invoked as they were by Einstein? A reistance to methodology and insightfulness to hold to a way of doing things that challenegd Dirac and cuased sleepless nights?



    Have a look at previous panel to this one.

    While indeed this blog entry open with advancements in the Test in Vienna, one had to understadn this developing view from inception and by looking at Penrose this sparked quite a advancement in where we are headed and how we are looking at current days issues. Smolin and others hod to the understnding f valuation thta is expeirmentally driven and it is not to far off to se ehosuch measure sare asked fro in how we ascertain early universe, happening with Glast determinations.

    Quantum Cryptography

    Again if I fast forward here, to idealization in regards to quantum computational ideas, what value could have been assigned to photon A and B, that if such entanglement states recognize the position of one, that it would immediately adjust in B?

    Spooky At any Speed
    If a pair of fundamental particles is entangled, measuring an attribute of one particle, such as spin, can affect the second particle, no matter how far away. Entanglement can even exist between two separate properties of a single particle, such as spin and momentum. In principle, single particles or pairs can be entangled via any combination of their quantum properties. And the strength of the quantum link can vary from partial to complete. Researchers are just beginning to understand how entanglement meshes with the theory of relativity. They have learned that the degree of entanglement between spin and momentum in a single particle can be affected by changing its speed ("boosting" it into a new reference frame) but weren't sure what would happen with two particles.



    So there is this "distance measure" here that has raised a quandry in my mind about how such a projective geometry could have superceded the idea of "spooky things" and the issues Einstein held too.

    So without understanding completely I made a quantum leap into the idealization in regards to "logic gates" as issues relevant to John Venn and introduced the idea around a "relative issues" held in my mind to psychological methods initiated by such entanglement states.

    As far a one sees here this issue has burnt a hole in what could have transpired within any of us that what is held in mind, ideas about geomtires floated willy Nilly about. How would such "interactive states" have been revealled in outer coverings.

    The Perfect Fluid

    Again I am fstforwding here to help portray question insights that had been most troubling to me. If suych supersymmetrical idealizations arose as to the source and beginning of existance how shall such views implement this beginning point?

    So it was not to unlikely, that my mind engaged further problems with such a view that symmetry breaking wouldhad tohave signalled divergence from sucha state of fluid that my mind encapsulated and developed the bubble views and further idealizations, about how such things arose from Mother.

    What would signal such a thing as "phase transitions" that once gauged to the early universe, and the Planck epoch, would have revealled the developing perspective alongside of photon developement(degrees of freedom) and released information about these early cosmological events.

    So I have advance quite proportinately from the title of this Blog entry, and had not even engaged the topological variations that such a leading idea could have advanced in our theoretcical views of Gluonic perceptions using such photonic ideas about what the tragectories might have revealled.

    So indeed, I have to be careful here that all the while my concepts are developing and advanced in such leaps, the roads leading to the understanding of the measure here, was true to form and revalled issues about things unseen to our eyes.

    It held visionistic qualities to geometric phases that those who had not ventured in to such entanglement states would have never made sense of a "measure in the making." It has it's limitation, though and why such departures need to be considered were also part of my question about what had to come next.

    Quark Gluon Plasma



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


    This form of matter is called quark-gluon plasma or QGP. Like its name suggests, QGP is a "soup", or plasma, of quarks and gluons.


    (see physics primer)

    RHIC Scientists Serve Up “Perfect” Liquid

    “The truly stunning finding at RHIC that the new state of matter created in the collisions of gold ions is more like a liquid than a gas gives us a profound insight into the earliest moments of the universe,” said Dr. Raymond L. Orbach, Director of the DOE Office of Science.

    Also of great interest to many following progress at RHIC is the emerging connection between the collider’s results and calculations using the methods of string theory, an approach that attempts to explain fundamental properties of the universe using 10 dimensions instead of the usual three spatial dimensions plus time.

    Dr. Raymond L. Orbach
    “The possibility of a connection between string theory and RHIC collisions is unexpected and exhilarating,” Dr. Orbach said. “String theory seeks to unify the two great intellectual achievements of twentieth-century physics, general relativity and quantum mechanics, and it may well have a profound impact on the physics of the twenty-first century.”


    So the issue is which blackholes would help point towards this supersymmetrical view that I jest in the Ipod post and the ipod that forms the perfect fluid? So this idea then about which blackhole has to have found some value in what I assign the new Ipod technology, that takes back to a time near the beginning of the universe.

    Some say if you have to explain the joke then it sort of devalues the joke. Not in this case if you move forward with it, and see what the latest is in research. Sort of "sets the stage" as I allude too, in this other article of cosmic variance's.

    A simple jesture is the question of course (Clifford reminds us here) and without it, how can you move perception forward? It's kind of hard to do that on your own, limited by the current knowledge one might have. So you in essence look forward to those areas that help direct this knowledge. For those who want to rehash the ID debate, only add fuel to the fire for the believers. Better to let it die it's own death and watch for the merits of scientific valuation that is brought forth through media. Speak directly to this only, and the refutation will be it's measure by it's own design.



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

    Give value to string theory where previous comments on the nature of experimental research has lacked luster for this approach? The name choosen for the new Ipod model was specific, as it provided for the idea that we can take this supersymmetrical reality closer to the beginning of this universe and use the BPS blackhole nature for this conisdertaion and resulting fliud nature realized?

    What conditions would provide for such a reality?

    So of course by incinuation what is the nature of this BPS Blackhole that I am refering. That will be the issue on the next post created.

    More Quantum Gravity Comments

    Aristotle: Commenced his investigation on the Wisdom of the philosphers. "Thales says that it is water" it is the nature of the arche, the originating principle. Water is the Nature of All Things"


    Now relax before you start assigning numerical values to the opening statement:) Might I see a greater context in the evaporation(decay), of course, and I will say I like to think all things have some issue in this regard? Some evidence?:)

    After I wrote my post below on quantum gravity and related Jacques comments, I was glad to find Lubos Motl and Peter Woit both had created similar posts to address this issue a little more deeply. Reference to John Baez was also very important, from the basis of clearing up the view points Peter holds to in regards to his feelings on quantum gravity as well.

    I know that my view is much distant from the qualified aspects of these gentleman have to offered. I find hope, that there might be this capable resolution to giving perspective to where perspective is needed. This is valuable to me, as I know with some conviction the idea of this landscape will not let go of my inquiring mind.

    Finding methods of application in the weak field measure were held in mind when dimensional significance was assign those extra dimenions. As we find the attempts at experimental verification less then satisfying, or the views to moon measure(?), it became clear to me, we already were doing things in this regard, and just were not privy to these views.



    I know too, to limited the alchemical relation or be torched on the ground of crackpotism rules assigned a numerical value to any opening statement, so I had to be careful here in referring to the Thalean view:) This aspect was consider when I held to view the new methods at dealing with gravity with our space born measuring eye to eye. I have nothing more to say about the too and fro, and the distant measurte her eof our global planet, that I would too consider the extension of the Reimannian view had also be extended by me and not limited as Peter might have thought.

    Lubos said:
    But that's not how it works in the quantum world. If an event is very "weak" - such as a decay of a light nucleus - quantum mechanics dictates that with a probability close to one, the process has *no* impact whatsoever on spacetime geometry (or the electromagnetic field); and there is a small probability that one produces one (or a few) gravitons (or photons).


    Although I would not like to invoke mysticism in this venture, the "weak field" view had amazed me when I understood that a measure would be capable in a new global perspective, spoken to here.

    While I had to remind of compassion that exists, I had to interrupt the flow of the site for a minute, so that perspective was brought back from all the political ramifications and warring views materializing about the oil and gas reserve that is being gobbled up from other countries to secure the resource for the United States.

    This did not look good to me, as I looked back to the views of the terrorism being fought in another land, might have also held the security of these reserves to lives willing to be sacrificed. That's all I wil say about this, and holding these thoughts, I wanted to continue to speak to that subject of quantum gravity regardless of the tragety taking place on our globe. I won't assignthese values to a God, becuase the science is still very compelling to me that we are limtied as always from a wquantum mechanical perspective that weather itself produces.

    So without these views on weak field measure I undertsood now that in my mind, this process was not needed in looking at the dimensinal valuation aldeberger and others are doing, becuase we can measure this gravity in ways tha we are not accustomed too.

    It is not bad a reason now to consider that this Thalean view although very wrong for our current day, I understood well "first principle" from his perspective was based on water. So to me finding this calibration point amidst the field qualites of a planet much greater in perspective to this ths beautiful globe of water, fresh water resources become critical issues with such large populatins covering the face of these land masses.

    So try as you might to argue with me about the tangibility of a landscape one is painted inhow weassign the relativity measure to our features of water pervasive ness amidst mas detrmination of hills and valleys. Thsi was a conceptually success in my mind even while good science minds are embroiled inthe requiremets of how to assign symmetry breaking froma supersymmetrical world, ther had to be some constant in thought. Some valuatin about th eidea of the landscape to make it applicable in how we loking at this functionin our world measures.

    No where did I mention the perfect fluid of the strong coupling, but iwas very aware of the nedd for the quantum mechanical process to be addrssed conceptually. I of course from layman views am stl subject to mistakes inmy views but I struggle hard to over come these by continuing to learn and watch.

    Here I would like to give credit to Clifford of Cosmic Variance for taking this discussin further, and the perception of Smolins for this integrative civilized discussion without invoking the Intelligent design issue. I have now gone past the resistance to landscape analogies to continue to perfect the view of a dimensional reality that few want to acknolwedge and deal with.

    If indeed I wanted to assign transcendance to the computer world, the sentient being would be one that recognizes that a world in graphic resoluiton, had now paved the way for the Thalean group of mathematicans who Peter Woit mentioned. Might these people break the barriers of mathematicians from the world of theoretical into the world of physics.

    I always had trouble understanding why theoretics would be so held in distain holding the mathemtic mind, but I understand this resistance when a personality would have been assigned, a ID classification, even though the physics had to be correlated in those same equations? They had to be able to operate at the edge, and continue on from that point.

    So indeed this point of mass assignation, is indeed a troubling one, while I still see fluidity as a continous feature of supersymmetrical view? Such allocations of discretion were less then appealing, although necessary, as a measure of the depth of perception. So how do we resolve it?:) I am not sure either, but for some strange reason I can't let go of the view of a continous nature, when left to see decay as a measure of what existed in another state.

    So of course we look for this trigger. This place where all might agree and if all created, started from such a place then how shall we assign our reason to what shall be the best way to proceed?

    I wanted to add Lee Smolin's comments here.

    Lee Smolin said:Of course if the theory is right-and we never assume so-we must show more. We must show that the ground state is semiclassical, by solving the dynamics. This is a hard problem, analogous to showing that the ground state of water is a solid. But as this is the focus of attention there are beginning to be significant, non-trivial results on how classical spacetime can emerge from a background independent quantum theory.

    More Views on the Landscape

    How would such a "landscape" bring string theory into better comprehension? The
    Most perfect fluid
    in face of strong coupling?

    Yet at the other end, there is no deviation?

    Eric Adelberger on Aug 12th, 2005 at 2:37 pm It is true that we are seeing an anomaly at shorter length scales but we have to show first that the anomaly is not some experimental artifact. Then, if it holds up, we have to check if the anomaly is due to new fundamental physics or to some subtle electromagnetic effect that penetrates our conducting shield. We are now checking

    Lubos being on top of it, reveals new paper.

    New Constraints on Yukawa-Type Deviations from Newtonian Gravity at 20 Microns

    Recent theories of physics beyond the Standard Model have predicted deviations from Newtonian gravity at short distances. In order to test these theories, we have a built an apparatus that can measure attonewton-scale forces between gold masses separated by distances on the order of 25 microns. A micromachined silicon cantilever was used as the force sensor, and its displacement was measured with a fiber interferometer. We have used our measurements to set bounds on the magnitude alpha and length scale lambda of Yukawa-type deviations from Newtonian gravity; our results presented here yield the best experimental limit in the range of lambda=6--20 microns.

    Don't cater to Intelligent Design debate Please?

    I would say attitudes from respectable scientists had more to do it with then any intelligent design debate. Any repeated pattern of news, associated. This debate was fuelled.

    While respected the stand taken against any position on "intelligent design" it would have been outright diagreement with the religious connotation for sure, then argue the basis of science assign to a differing group opinion. I stayed away from the source of this debate arising, as I watched Sean, Peter Woit and others villify and characterise(news jumped on this), a respective theoretical view, based on such association.

    This hurt propsective views on recogniton of theoretical position.

    The debate had to be rested in science, and any distinction of religion dropped from the conversation. Only the reason why such rejection, and such slogans pasted on other views contained. Lee Smolins attempt to draw other so science, and Lubos's attempted to clarify current scientific data. Argue then, Georgi Dvali's moon measure?

    String Connection?

    The possibility of a connection between string theory and RHIC collisions is unexpected and exhilarating,” Dr. Orbach said. “String theory seeks to unify the two great intellectual achievements of twentieth-century physics, general relativity and quantum mechanics, and it may well have a profound impact on the physics of the twenty-first century.”


    In this narrow class of theories, the hot plasma in the 4D theory corresponds to a black hole in the 10D equivalent description, which matches very well with Stephen Hawking's prediction that black holes have temperature. Moreover, there is a direct relationship between vibrations in the plasma, such as sound waves, and vibrations of the black-hole horizon. For example, when an object is dropped into the black hole in 10D, the equivalent picture in 4D is a hot, expanding region that dissolves into a plasma. Using this equivalence, various theorists, including the present author, have deduced that if such plasmas were real, they would be almost perfect liquids.

    Since Maldacena's conjecture does not apply to QCD, however, the viscosity of the real quark-gluon plasma cannot be computed via string theory. This makes the RHIC announcement that the viscosity of its plasma is comparable to the values one finds from string-theory calculations even more surprising. If this is true, the quark-gluon plasma created at RHIC could be the most perfect fluid in nature. This in itself is an interesting fact, but it could also indicate that string theory has some relation to real QCD. However, we first need more quantitative evidence from RHIC, such as an upper bound on the viscosity.


    Blackholes at RHIC


    A statement from RHIC theoretical nuclear physicist Dmitri Kharzeev:


    Alice



    The existence of such a phase and its properties are key issues in QCD for the understanding of confinement and of chiral-symmetry restoration. For this purpose, we intend to carry out a comprehensive study of the hadrons, electrons, muons and photons produced in the collision of heavy nuclei. Alice will also study proton-proton collisions both as a comparison with lead-lead collisions in physics areas where Alice is competitive with other LHC experiments

    Blackhole Production and Sonluminence




    John Ellis:The quark-gluon plasma - if it exists and is being produced at RHIC - is considerably more complicated than was thought a few years ago. It seems to be an almost perfect, strongl-interacting fluid with very low viscosity. Theoretically, there have been some very interesting developments relating the plasma to string theory, as well as strongly-coupled supersymmetric gauge theory and ideas from condensed-matter physics, e.g., in nano-Kelvin Bose-Einstein condensates.

    I have been interested in finding a consistent geometrical/topological system to undertanding our universe. When we look to the reductionistic principles, I couldn't help but be attracted to the idealization of bubble nucleation, and if such was the case, then such an idea had to emerge from a very hot time.

    Can we entertain such bubble nucleations within the context of these experiments?

    Would M theory have then found it's experimental counterpart? The Bose Nova and Jet idea from collapsing bubbles has been part of the vision I speculated in what Heisenberg saw in the geometrodynamics of a nuclear explosion. See, not only were we detonating a nuclear reaction(gravitational collapse), but we were doing something beyond the perception, by going to the heart of these particle collisions.

    Part of this process for me, was looking for a situable framework in which the gravitational collpase could induce the geometrics /topological explanations that would go hand in hand with these processes. So as theoretical this may sound, before such plasmatic states of existance are developed, what would we see at this level in relations to such bubble nucleations?


    The second plume of antimatter was unexpected and has yet to be explained. "The origin of this new and unexpected source of antimatter is a mystery," said Northwestern University physics professor William Purcell.


    In the Bose NOva such jets would seem beyond the approach of the micrososmic idealization but if such consistancies could exist, how would we describe the relationship between the very large to the very small? The geoemtrics/topological would have to be compatible?

    So in looking for this way in which such energy could go through a increase to generate the needed energy, the collapse of the blackhole would initiate this energy production by tapping the source?

    Such Gravitonic condensation would have initiated the booms by contracting the blackhole. Such allegorical relations were developing in my mind about how such gravitons could amassed from such intiated responses, that I looked to sonoluminece as to how such nuclear reaction could have been initiated for energy creation?

    I then saw such relations on how grvatons would have been move within the balckhole in comparative sounds vibration being moved witin t ebubbles for reaction. All highly speculative on my part and of course needing correction.
