Time-Variable Gravity Measurements



Mean Gravity Field


The Mean Gravity Field lets us work from this mass understanding and provides for, flunctuations in that Gravity field hence the understanding of Time Variable Gravity Field


On planet Earth, we tend to think of the gravitational effect as being the same no matter where we are on the planet. We certainly don't see variations anywhere near as dramatic as those between the Earth and the Moon. But the truth is, the Earth's topography is highly variable with mountains, valleys, plains, and deep ocean trenches. As a consequence of this variable topography, the density of Earth's surface varies. These fluctuations in density cause slight variations in the gravity field, which, remarkably, GRACE can detect from space.


I wanted to put this into perspective, since we can extend our vision of the gravity field, and how we would look at mass distribution. Using this method, we calibrate, understanding current topological features of hills and valleys that serve to remind us, of the mass distribtuion that has gone on in the formation of our planet Earth.

Since passing over these locations calculations recognize these density valuation of mass regions. This allows us to understand the current gravity standard placed on that location.

Time-Variable Gravity Measurements from the GRACE Satellite


NASA, in partnership with the German Space Agency DLR, launched the dedicated gravity satellite GRACE (the Gravity Recovery and Climate Experiment) in March, 2002. This five year mission will map out the Earth's gravity field to unprecedented accuracy at monthly intervals. The temporal variations in gravity inferred from these data will allow people to study a wide range of processes, cutting across a variety of Earth science disciplines, that involve redistribution of mass within the Earth and at or near its surface. It will be possible, for example, to produce monthly estimates of changes in continental water storage anywhere in the world, averaged over scales of a few hundred km and greater, to accuracies of better than 1 cm water thickness.


I have referrred to the hill and valley perspectives that have arisen in relation to how we see the landscape(earth's). If this feature was not comprehended in some model application, would it not have served to settle minds who see no valuation in such landscape perspectives, as a basis to a much better understanding of the nature of the universe, and the reality around us?

Where has the extra energy gone? For some scientists this question highlights something interesting about what extra dimensions might have implied? You gauge the gravitational fields and learn to see time variability as a feature not just of mass consideration, but of energy determinations as well. It's only fitting?:)


The image above shows the many processes of the Earth’s hydrologic cycle that contribute to total changes in water storage


So setting up a comprehensive understanding of these differences, the mean gravitational field and Time Variable gravity field we see now some relationship to things finer in its constitution, and the relationship to Climate.


The Landscape?


What value might be assigned to this understanding, that we look at how such emissions and its effect on the information gathered. Would we see the effect of civilizations and the way this has effecedt those particular geographical regions.

Have we thus found a legitimate model, that current debates on the Kyoto protocals might serve to get everyone on base for determinations. Will this effectvely change the dialogue currently going on in our assessments, of the needed reduction of CO2 emissions?

Here, each arrow represents a symmetry breaking phase transition where matter changes form and the groups - G, H, SU(3), etc. - represent the different types of matter, specifically the symmetries that the matter exhibits and they are associated with the different fundamental forces of nature


"Nothing to me would be more poetic; no outcome would be more graceful ... than for us to confirm our theories of the ultramicroscopic makeup of spacetime and matter by turning our giant telescopes skyward and gazing at the stars,"
Greene said.





Peter Woit:
Brian Greene was in the audience and somewhat objected to this. Brian's point of view appears to be the more traditional one that people should just try and cook up vacua with as many features as possible close to the Standard Model, and that once they've got such a thing it will have other implications for physics that can be checked. It seems to me that that kind of work has been going on for more than twenty years with no sign of success, but Brian still believes this will ultimately work out.



To me the idea of bubble dynamics is quite revealling when you place the context and question of the dynamics as underlying feelings(this is quite subjective). Much like GR, and these momentus occasions, that can move within our natures, as our comprehension grows. Time experienced in different ways, does this for us?:)It can still be a highly visula thing?:)

To not be mistaken, the questions materializes in the reasons why such dynamics may have been offerred in the same vain as GR, to see that this features becomes a signature of conscious effort, where what is being replaced, reveals some dynamics of the true vacuum?:)

So of course there are questions that need to be resolved. Some might not like to answer them and censor the blog of their own, so that blanket policies regardless of the question, is like who gives a **** about what you think in context of the larger picture of things. Of course they have their own agenda and have the right. It's their blog. I am quite greatful by such resistance presented, has forced me to expand here, where the truth of what I am seeing can be demonstrated.

But I have digressed some from the important question that is raised not only in Serkan's mind but mine as well. So resource info helps in perspective here.

Is QFT vacuum real?

Serkan Cabi:Almost everybody cite the Casimir effect as the proof of reality of quantum ground state of standard model fields. Lately it has become a commonsense especially in the dark energy literature, as an aspect deepening the problem.

So to me looking for an explanation of ths dynamics is a hard one to qualify as it suggested by some, that one wonders about the way early supersymmetrical idealizations have brought consideration to what emerges from these hottimes?



But there are other ways here, that having gotten a grasp of this elasticity of a membrane, that one can see how certain features are held too and others, are presented for further developement in the nature of those same psyches? Imagine introducing this memebrance and the elasticity. What has the mind grasped now?

Below Serkan helps to point out more info for consideration.

The Casimir Effect and the Quantum Vacuum
I have presented an argument that the experimental confirmation of the Casimir effect does not establish the reality of zero point fluctuations. Casimir forces can be calculated without reference to the vacuum and, like any other dynamical effect in QED, vanish as a→0. The vacuum-to-vacuum graphs (See Fig. 1) that define the zero point energy do not enter the calculation of the Casimir force, which instead only involves graphs with external lines. So the concept of zero point fluctuations is a heuristic and calculational aid in the description of the Casimir effect, but not a necessity.


This does not do away with the idea of what can happen within the confines of a vacuum, but ultimately, we realize that the speed of light remains the same, yet other dynamics when playing with physical things, can display wonderful intentions about about this elasticity nature?



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.


So it is a highly specialize vision that I had been moving towards that I wanted to make sure any bubble technolgies would encase all that we learnt. That we define the further reaches of what this bubble( K=0 before the crunch begins) might have encompassed? Revealled that outer value(K=0) of Friedman's equation and Omega in terms of what critical density would have expounded? In terms of the distance this bubble could grow, in this inflationary universe?

Outside this bubble universe, is a dimensionally filled universe that had grown as this bubble grew?

Such movement in propelling our universe to expression, seems quite a challenge, so having encompassed this larger view of reality, inverse square law would have exemplified the schwarzchild radius, determining the total expansive view of this cosmos?

You had to be able to confine this view and encapsulate it so that the total view developed through the phases of standard model production would have evetually helped us realize the wide scope this particle reductionism and cosmological endeavors had revealled with distances(large and small) joining?:)

Collision course creates microscopic 'black holes'


Physics At The End Of The Galactic Cosmic Ray Spectrum will take place in Aspen, Colorado at the Aspen Center for Physics from April 26 to 30, 2005.



Sean Carroll:
Among other responses to the post about fundamental physics in the U.S., there was a position that one occasionally hears: "Who cares about particle physics, we can just do astrophysics instead, it's cheaper and more fun." I've heard this claim even (especially?) from people who have been experimental particle physicists themselves, and have decided to move into astrophysics. This is actually quite an established career path, although not always the easiest one.


This is ole news with leading ideas to consider. Sean's post also directs some reasoning behind this move to astrophyiscs and the relevance it can play where reductionistic understanding having now, related common bonds for consideration with GR. Have we thus found a way to bring together perspectives that help us realized that we are ever more direct in our pursuate?

By Dan Vergano, USA TODAY

On top of that, spotting many black holes would bolster fashionable theories that explain gravity by suggesting that other dimensions — beyond familiar ones such as height, depth and time — exist "curled up" and hidden in the universe.

Measurements of the black holes and their energies would suggest exactly how many hidden dimensions exist. Even if no black holes turn up, the pair suggest science will benefit from results that poke holes in the extra- dimensions theory.

Many physicists find extra dimensions a distasteful notion. In remarks to an American Physical Society newsletter, physicist Frank Wilczek of MIT called the black hole study a sound way to test an unattractive idea.

"There's no question that the Auger observatory will be sensitive to this signal, if it exists," says Penn State's Stéphane Coutu, a member of the international Auger Observatory team. "We'll definitely look."

Pierre Auger Observatory


In his excellent paper, Louis LePrince-Ringuet, citing a remark of Powell's at the Conference of Bagneres-de-Bigorre in 1953, declared that from that date on, particle accelerators took the place of cosmic rays, which more or less faded into the background. And yet, even today accelerators have not caught up with cosmic rays.


Pierre Auger on Cosmic Rays


"For in 1938, I showed the presence in primary cosmic rays of particles of a million Gigavolts -- a million times more energetic than accelerators of that day could produce. Even now, when accelerators have far surpassed the Gigavolt mark, they still have not attained the energy of 1020eV, the highest observed energy for cosmic rays. Thus, cosmic rays have not been dethroned as far as energy goes, and the study of cosmic rays has a bright future, if only to learn where these particles come from and how they are accelerated. You know that Fermi made a very interesting proposal that particles are progressively accelerated by bouncing off moving magnetic fields, gaining a little energy each time. In this way, given a certain number of "kicks," one could perhaps account for particles of 1018 -- 1020 electron volts. As yet, however, we have no good theory to explain the production of the very-high-energy particles that make the air showers that my students and I discovered in 1938 at Jean Perrin's laboratory on a ridge of the Jungfrau."
-- Pierre Auger, Journal de Physique, 43, 12, 1982



On the vast plain known as Pampa Amarilla in western Argentina, a new window on the universe is taking shape. There the Pierre Auger Cosmic Ray Observatory has begun its study of the universe's highest energy particles. These rare messengers should tell an important story about how they originate. Experiments have so far failed to decipher their message, and their existence has become a profound puzzle. The Auger Observatory is attacking this enigma of the highest energy cosmic rays with unprecedented collecting power and experimental controls.




John Ellis:
The next step will again be taken in Japan, with the new J-PARC accelerator starting in 2009 to send neutrinos almost 300 km, again to the Super-Kamiokande experiment, to probe the third neutrino mixing angle that has not yet been detected in either atmospheric or solar neutrino experiments. This may also be probed in a new experiment being proposed for the Fermilab NuMI beam. One of the ideas proposed at CERN is to probe this angle with an underwater experiment moored in the Gulf of Taranto off the coast of Italy, viewing neutrinos in a modified version of CERN's current Gran Sasso beam.



Aussois, Savoie, France
After "Neutrino 2004" the convergence of results from atmospheric, solar, reactor and accelerator experiments confirms the massive neutrino and gives the first opportunity to test physics beyond the Standard Model. The neutrino oscillations picture is still missing 3 fundamental ingredients: the mixing angle θ13, the mass pattern and the CP phase δ.

Future neutrino beams of conventional and novel design aimed at a megaton type detector could give access to these parameters. Such a detector would also be the next generation facility for proton decay searches and an invaluable supernovae neutrino observatory.




To understand the Higgs mechanism, imagine that a room full of physicists chattering quietly is like space filled with the Higgs field ...


So who is the professor that crosses the room? It is Albert Einstein:)


Any such Blackhole would quickly decay into a shower of Hawking radiation (mainly into standard model particles on our brane, rather than into grvaitons into the bulk). This shower of radiation would be quite different from showers arising from, say, the collsion of cosmic-ray proton with a atmospheric atomic nucleus. Gravity is "flavor blind," so when a microscopic blackhole evaporates it produces all the Standard Model particles with equal probability. Once one accounts for spin and color, it turns out that particles produced when a blackhole decays are about 72 percent quarks and Gluons, 18 percent leptons, and the rest are bosons. Such a distinctive shower of particles would be hard to miss. So there is the possibility that the Pierre Auger Observatory will detect blackholes.

Two of the tanks in the Pierre Auger Observatory are shown. They each hold 12 tonnes of clean water and are viewed by 3 X 8” diameter photomultipliers. The electronics for recording and data transmission are powered by solar cells. These tanks are placed close together so that cross-tank measurements of densities and arrival times can be made but the nearest neighbour for all other tanks is 1.5 km away. In this way 3000 km2 can be covered with only 1600 detectors.

Supersymmetrical Realities

Fusion Power Within Reach?

Controlling the eddies and whirls of the writhing plasma so that it can burst into life as a miniature Sun has been a formidable, and so far only partially met, engineering challenge.

"If we follow the Mast idea and not the Jet one, we could imagine a string of medium-scale fusion reactors instead of a few very big ones," said Dr Sykes


I was well aware that this is a troubling issue for a lot of people and having found some geometrodynamical explanation and fluidity in coninous expression we had to move our current understanding into the non-euclidean realms.



I have been looking at this process trying to comprehend how this feature of the universe could have ever come into existance? So I was looking for ways to help me determine how such states of existance, at the beginning of the universe could have ever signalled the rebirth of the cosmos and it's potentials.

The Sudbury Neutrino Observatory


Understanding John Ellis's work here in microstate blackhole developement, was part of this view that would direct our questions to the rejuvention process in the reality around us. Any attempts to further define reality in a "negative sense," would run into trouble with supersymmetric valuations to model assumptions?Recognizing the weak field manifestations present in gravity determinations, makes this a interesting idea in face of what we see around in our response to the sun and what energy approaches us, for interactions in these giant baths, or the Auger experiment?

Star In a Jar


During a single cycle of the sound field, the pressure exerted on the bubble (green) follows a sinusoidal pattern. The bubble radius (red) expands during the rarefaction part of the sound field and collapses during the ensuing compression. At the minimum radius, a photomultiplier trained on the bubble records a flash of light (blue). The implosion also generates an outgoing pulse of sound detected by a microphone about 1 mm from the bubble, as shown by the spike on the sound wave. The time delay between the collapse and this spike is due to the finite speed at which sound propagates in water.


I have been following this progress for reasons that would help me understand the geometrical/topological possibilties, such expressions might help in determining these underlying causes as Einstein demonstrated as we moved to Elliptical Geometry of Reimann.

SONOFUSION – FACT OR FICTION?
The fact that we have a bubble cluster (rather than a single bubble) is significant since when the bubble cluster implodes the pressure within the bubble cluster may be greatly intensified [Brennen, 1995], [Akhatov et al, 2005]. Indeed, figure-10 [Nigmatulin et al, 2005] shows a typical pressure distribution (where r = Rc is at the edge and r = 0 is at the center of the bubble cluster during the bubble cluster implosion process. It can be seen that, due to a converging shock wave within the bubble cluster, there can be significant pressure intensification in the interior of the bubble cluster.


The physical processes underlying the phenomenon of sonoluminescence have not been clearly resolved by previous measurements. The possibility that sonoluminescence might involve such extreme conditions that it could produce neutrons makes measurements of parameters such as the source temperature, diameter, and density valuable. We report attempts to measure the diameter and duration of single sonoluminescence flashes. For both parameters, our results were limited by the resolution of the instruments, giving upper limits on source diameters of three microns and upper limits on emission durations of twelve picoseconds.


As I was saying, to get to these supersymmetrical realities, such convergenances of of sound analogies were quickly adopted as signs of what gravitonic perception might help in distinquishing the concentration and hence cyclication? This would help explain that early universe. This basis of geometric/topological approach was the basis of my exploration, for I see such comprehension necessary in the determination of a consistent method of approach?

This lead to the insight of the nature of the bubble explosions and contrasts to current consideration presented by blackhole radiation. How could this ever become possible to know that the size of ths bubble would have reached a critical point and found entropic issues like expansion relevant to the cooling features of our universe now? CMB was relevant to the state the universe was in and it's curvature, based on Friedmann equations. As to whether or not, such a crunch was emminent.


The team believes this method can be modified to make the bubble collapse even faster, which would lead to greater light intensities. This would allow physicists to study the relationship between pressure, light intensity and temperature in sonoluminescence in more detail.


Once it becomes apparent that we would look for such models for comparing current states of existance with the supersymmetrical realities it was very important to distinquish early uiverse formation to infomration released from supernova explosions. Consder what was what was released into the bulk.

According to Didenko and Suslick, this suggests that chemical reactions would soak up too much of the energy for nuclear fusion to take place, especially for bubbles in volatile liquids like acetone. The molecules of vapour in such bubbles are complex, and would absorb much more energy than the water vapour that they studied. But Suslick does concede that "the possibility of fusion occurring in low-volatility fluids - such as liquid metals and molten salts - cannot be ruled out at this time."

Such topological expressions had me wonder how could such expresssion ever be considered, if we did not have some method in which to ascertain the early universe? Could it have reached supersymmetrical proportions and with this, the cyclical nature of expression. One needed the blackhole for this.


Kenneth Suslick
When a gas bubble in a liquid is excited by ultrasonic acoustic waves, it can emit short flashes of light suggestive of extreme temperatures inside the bubble. These flashes of light, known as 'sonoluminescence', occur as the bubble implodes, or cavitates. Now Didenko and Suslick show that chemical reactions occur during cavitation of a single, isolated bubble,and they go on to determine the yield of photons, radicals, and ions formed.

Researchers Report Bubble Fusion Results Replicated

Earlier test data, which were reported in Science (Vol. 295, March 2002), indicated that nuclear fusion had occurred, but these data were questioned because they were taken with less precise instrumentation.

“These extensive new experiments have replicated and extended our earlier results and hopefully answer all of the previous questions surrounding our discovery,” said Richard T. Lahey Jr., the Edward E. Hood Professor of Engineering at Rensselaer and the director of the analytical part of the joint research project.

Cosmological and Microstate Blackholes



Perspectives On Nature's Greatest Puzzles

Nima Arkani-Hamed
:
First rule of progress in science-better to follow your nose, then twiddle your thumbs



My perspectives are elementary generalizations from the views of those at the forefront of theoretcical research into comprehenson of the nature of this cosmo and the ideas of it's cyclical nature. Where else shal we consider this rebirth of sorts but to have been taken to the origins and how we percieve this same universe?

From the general public perspective concepts, which are developing will never make sense, if they did not understand the work that brought these two perspectives together and created this trend to the cosmological pallette for fun, with the theoretical approaches seen in high energy considerations?

Once these views of the cosmological design were contemplated, they revealled a deeper intricacy into the geometry/topological considerations. It was not to far a leap to considered the early universe foundations in the gravitational collapse of those same blackholes, would lead us to the ideas in high energy considerations.


Has the Track Record Been Poven?

Nima Arkani-Hamed:
Our Mantra:
LHC + L.C. will reveal natural theory of weak scale



Once it was understood that such balckhole creation could be idealic produced in the in high energy considerations, the expansive technique to developemental policies quickly reocgnized the diversity? With how the new views would form in minds which had been enaged in string theory. To understand well this covering, that had been placed over all the perspective leading through the standard model comprehension mode. They had discovered the nature of this cyclical universe already?:)

Should this be transcended into allotment of financial gain and to push perspective into the most approrpiate directions? Was it was safe and sound enough in the work that had been moved into the idealization of those same microstate blackholes, then the choice given John Ellis and others would have been far reaching in what direction such courses of event would lead too, into the future.

Having recognized that these trends would now force the move from theoretical design to one of experiementalist having developing proofs , John moves us forward here in the developement phase of cosmological interactions taking place in the field of experience of our earth and it's relation with the sun.

LIGO Translation

But lets not forget the work LIGO has done in transforming our views of the early history. Webber, John Wheeler and Kip Thorne and others, took it upon themselves to orientate the view not once, but many times to see where such progression has lead to the developement of LIGO operations and Detection.

This forced the current trends in string research to produce students that would move this subject into new directions? Now geared to questions of what that gravity might have surmised in its expression and developement. Hence the title of this thread.

Symmetry: Dimensions of Particle Physics

I thought it important that I present the infomrtaion that was tied to John Ellis's article in previous thread below and what was happening in regards to Microstate blackhole recognition.


Let it Rain
The most energetic particles in the universe have a message for us. The gigantic Pierre Auger Southern Observatory, still under construction in Argentina, is already trying to decipher it.
By Davide Castelvecchi


Most people I have read reveal the silence of common information, as a realization of Blackholes as the cosmological design, we like to play with. But when it comes to testing these extra dimensions, imagine indeed, that such length's we go too, helps us to adjust to what happens around us everyday.

From this conceptualization, much has changed in the propspective views? Staunch supportors of rejection, do not realize what could be implied of the extra energy dissappearing and how you would measure it, in our everyday surroundings?.

I give a philospohical explanation to help explain the realization of how we see in these extra dimensions The earlyhsiory of extending these ideas, calls for more educative functions with those who do not understand this extension and theoretics going out on this limb. Should it be so easily dismissed?


If you do not follow this history, you will never understand what Nima Arkani-Hamed, Sava Dimopoulos, and Gia Dvali been doing with extra dimensions. There is a conceptual feature here that I have spoken too in regards to gravity that few understand.


So as we see Einstein's Bubble, we come to recognize the consistancy with which we would engage information that arises from such bubbles being burst. They give us information about the contents of these spaces, and from such light, we wonder what has been revealled? Cosmologiclaly the whole universe is teaming with the understanding that there can never be this zero function? To have realize it is a very dynamcial process that is continous and cyclical in nature?

Underlying this view of a cyclical nature, is the realization that such events are geometrically/topologically driven and schematically express the whole frame work of this discussion. How suttle it is sometimes, that we would be dismayed by physicists who are speaking about the geometrics/topological functions, to realize they are incorporating the realizations of this contraction/expansive feature, not only in the cosmo, but in how we see into the nature around us now.

Of course this is from a junior mind on these things in terms of education, but hopefully the vsion and eyesight, is well enough that such discriptions displayed, has viable perspectives to share?

Einstein's Bubble

If we wanted to understand this motivation and analogy using Einstein's bubble, how could we move this motivation to consider it's first expression, lies wihtin the bath of possibilties?

One needed to see this physics process in its whole harmonious view, to understand that even strings only tells us part of the story. If we disc the supersymmetrical reality, then how will you ever assume that this emergence had to come from some situation. That it is described by recognizing the pre-existing steps that will make this supersymmetrical reality possible for such expressions?


Afshar has done a variation of the standard two-pin-hole "welcher-Weg" optics experiment, in which he demonstrates that wave interference is present even when one is determining through which pinhole a photon passes. This result is in direct contradiction to Neils Bohr's Principle of Complementarity, which would require in the quantum world that when one is measuring particle properties [formerly read "measuring quantum properties" -KC], all wave interference phenomena must vanish. Afshar's trick is to find the location of the minimum points of wave interference, place one or more wires at these minimum points, and observe how much light is intercepted when one is determining the pinhole through which the photons passed.


I just wanted to add the following little blurb to show that the idea used here by John Cramer is one that many people like to use when we come to describing things if they contain others ways of describing?


Nathan Seiberg, a colleague of Witten's at the IAS, uses the analogy of blind men examining an elephant to explain the course of string theory until 1995. "One describes touching a leg, one describes touching a trunk, another describes the ears," he says. "They come up with different descriptions but they don't see the big picture. There is only one elephant and they describe different parts of it."The Guardian


So in this context John Cramer takes us through some information for consideration. This is also in context of the Welcher Weg experiment that is introduced on Lubos's site. Had he some search function I am sure he can take us directly to his continue discourse on this topic to help us orientate a better view of the issues. A little nudge again, like he's going to listen to what I have to say, eh?:)


The Blind Men and the Quantum: Adding Vision to the Quantum World

Question (Albert Einstein):

If a photon is detected at Detector A, how does the photon’s wave function Y at the location of Detectors B & C know that it should vanish?

Situation: A photon is emitted from an isotropic source. Its spherical wave function Y expands like an inflating bubble. It reaches a detector, and the Y bubble “pops” and disappears.

CERN and Future Experiments



I needed to come back down to earth for a minute to see where the trend is going with those who shall lead us poor earthlings into the future of experimental research and profound understandings.

It would be nice to see perspectives by Lubos, PeterWoit the group here(meaning their blogs), as we look in this direction for a moment? Peter might be able to set his Dirac Moduli space views here?:)

Peter Woit for emphasizing the importance of the Dirac operator on the moduli space of Calabi-Yau four-folds and the importance of string theory to him.


The next step will again be taken in Japan, with the new J-PARC accelerator starting in 2009 to send neutrinos almost 300 km, again to the Super-Kamiokande experiment, to probe the third neutrino mixing angle that has not yet been detected in either atmospheric or solar neutrino experiments. This may also be probed in a new experiment being proposed for the Fermilab NuMI beam. One of the ideas proposed at CERN is to probe this angle with an underwater experiment moored in the Gulf of Taranto off the coast of Italy, viewing neutrinos in a modified version of CERN's current Gran Sasso beam.



So having quickly gone today I went to look at John Ellis site, and was formally introduced to some of the things that have been happening with him and avenues of experimentation that seem very interesting to me.

High Energy Physics Group

The Theory of Cosmic Rays


Cosmic rays, which have historically provided the first tool to study high-energy phenomena, are playing a new role in modern physics. The origin of high-energy cosmic rays, gamma rays and neutrinos is still an open question in astrophysics. On-going and future experiments will give us new information on astrophysical sources and on high-energy processes.


It still retains high energy considerations even in face of LHC questions about particle reductionism and the effects of dynamical interrelations as we see this travel in neutrino functions. I wanted to point to further information here in terms of micro-state black-hole detection. I get this soon.


2004 promises to be an exceptionally exciting year in General Relativity and Gravitation: the LIGO/VIRGO/GEO/TAMA network of detectors has begun generating scientific results, ushering in the era of gravitational wave astronomy. These detectors will search for gravitational wave signals of the collision of black holes, neutron star mergers and other astronomical events previously undetectable. The fundamentally new science of gravitational wave astronomy opens up a new window on the universe. Up until now, astronomy has relied on observations of electromagnetic wave signals (e.g. visible light, radio waves). The detection of gravitational waves offers a completely new perspective on the universe: they will enable us to "hear" the cosmic orchestra as well as to see it! GR17 will provide the scientific community with one of the earliest opportunities to discuss the first scientific results of this era.


I wanted to add a little more information here to further bolster this idealization that I have found in Brian Greene's statement about turning our views skyward in the hope of seeing strings and cosmological thinking in a new way.

Flight of the Phenix

If mini black holes can be produced in high-energy particle interactions, they may first be observed in high-energy cosmic-ray neutrino interactions in the atmosphere. Jonathan Feng of the University of California at Irvine and MIT, and Alfred Shapere of the University of Kentucky have calculated that the Auger cosmic-ray observatory, which will combine a 6000 km2 extended air-shower array backed up by fluorescence detectors trained on the sky, could record tens to hundreds of showers from black holes before the LHC turns on in 2007.
