What is Dark Matter/Energy?

When Chaos Goes Quantum?

All events shown here (except KEK test detector) were generated by Monte-Carlo simulation program, written by Clark. The visualizing software which produced the detector images was written by Tomasz.


While the sun was easily recognizable building "monte carlo" patterns in computer technology developed from SNO work made such views easily discernible?

Imagine putting all that information through a single point? That "point" is important in terms of the energy perspective. It reveals something very interesting about our universe.

If such experiments as listed here are to be considered in the "forward perspective" then what do you think we have gained in our understanding of supersymmetry? Yes indeed, the undertanding is amazing with the reading of what is given to us below in the Interaction.org links.

The complexity of the information seems well, like, "ligo information" being transcribed into a working image of the cosmos? Complexity of all that information/energy is being processed through the LHC experiment. Consider it's energy values, and all that is being produced as "particle constituents" and yes, there is more.

Cosmic particle collision understanding in this correlation of experiment at LHC, we learn much about the universe.

Quantum physics has revealed a stunning truth about “nothing”: even the emptiest vacuum is filled with elementary particles, continually created and destroyed. Particles appear and disappear, flying apart and coming together, in an intricate quantum dance. This far-reaching consequence of quantum mechanics has withstood the most rigorous experimental scrutiny. In fact, these continual fluctuations are at the heart of our quantum understanding of nature.

The dance of quantum particles has special significance today because it contributes to the dark energy that is driving the universe apart. But there’s a problem: the vacuum has too much energy. A naive theoretical estimate gives an amount about 10120 times too large to fit cosmological observations. The only known way to reduce the energy is to cancel contributions of different particle species against each other, possibly with a new symmetry called supersymmetry. With supersymmetry the result is 1060 times better—a huge improvement, but not enough. Even with supersymmetry, what accounts for the other 60 orders of magnitude is still a mystery.

Physics theory predicts that one of the most important particles in the quantum vacuum is the Higgs particle. The Higgs pervades the vacuum, slowing the motion of particles, giving them mass, and preventing atoms from disintegrating. Since it fills the vacuum, the Higgs itself contributes to the embarrassing factor of 10120.

The next accelerators are opening a window on the pivotal role of symmetry in fundamental physics. New discoveries will teach us about the role of the Higgs particle and supersymmetry in defining the vacuum. Such discoveries are key to understanding what tames the quantum vacuum, a topic that is fundamental to any real understanding of the mysterious dark energy that determines the destiny of our cosmos.


It took me a long time to get to the very point made in terms of the supersymmetrical valuation by understanding what existed "before" was transform from to being by presented another possibily on the other side.

"In fact, these continual fluctuations are at the heart of our quantum understanding of nature."

The only known way to reduce the energy is to cancel contributions of different particle species against each other, possibly with a new symmetry called supersymmetry.


It had to be taken down to a reductionistic point of view in order for this to make any sense. You needed experiments in which this was made possible. Without them, how could we be "lead by science?"

Conclusions


Particle physics is in the midst of a great revolution. Modern data and ideas have challenged long-held beliefs about matter, energy, space and time. Observations have confirmed that 95 percent of the universe is made of dark energy and dark matter unlike any we have seen or touched in our most advanced experiments. Theorists have found a way to reconcile gravity with quantum physics, but at the price of postulating extra dimensions beyond the familiar four dimensions of space and time. As the magnitude of the current revolution becomes apparent, the science of particle physics has a clear path forward. The new data and ideas have not only challenged the old ways of thinking, they have also pointed to the steps required to make progress. Many advances are within reach of our current program; others are close at hand. We are extraordinarily fortunate to live in a time when the great questions are yielding a whole new level of understanding. We should seize the moment and embrace the challenges.


A new LHC experiment is born, is an effect from what existed before? What come after.

Yes, the idea is that universe was not born from colliding particles, but from the supersymetical valuation that existed in the universe in the very beginning. You had to know, how to get there. That such events are still feasible, and are being produced cosmologically as we see evidenced in the "fast forward" experiment.

Graviton in a Can?

After you consume "graviton in a can," you might never be the same? Brane thinking may then dominate your every view of the world. Then, it will all make sense?

Imagine while we peer deeper into the subject of the "perfect fluid/soup" we find that certain aspects of the reductionist work done, has indeed lead us to speculate on how the "new physics" formed through the research and understanding currently being worked in the LHC?

Is there some architectural design to the "Degree's of Freedom?" Why anything more then the spacetime we have come to recognize, which placed new parameters on our thinking? Moved it from the recogition of Maxwellian and Gaussian coordinates to Riemann geometries in the theory of General Relativity, to become known, as the Theory of gravity. Why "anything" more then that?


A picture of flux lines in QED (left) and QCD (right).
Although it didn't properly describe strong interactions, in studying string theory physicists stumbled upon an amazing mathematical structure. String theory has turned out to be far richer than people originally anticipated. For example, people found that a certain vibrational state of the string has zero mass and spin 2. According to Einstein's theory of gravity, the gravitational force is mediated by a particle with zero mass and spin 2. So string theory is, among many other things, a theory of gravity!


I mean how are such abstract notions in the mathematics supposed to make sense, if we can not see the logic of these formulations working in some kind of reality frame of reference?


by Jacob D. Bekenstein
TWO UNIVERSES of different dimension and obeying disparate physical laws are rendered completely equivalent by the holographic principle. Theorists have demonstrated this principle mathematically for a specific type of five-dimensional spacetime ("anti–de Sitter") and its four-dimensional boundary. In effect, the 5-D universe is recorded like a hologram on the 4-D surface at its periphery. Superstring theory rules in the 5-D spacetime, but a so-called conformal field theory of point particles operates on the 4-D hologram. A black hole in the 5-D spacetime is equivalent to hot radiation on the hologram--for example, the hole and the radiation have the same entropy even though the physical origin of the entropy is completely different for each case. Although these two descriptions of the universe seem utterly unalike, no experiment could distinguish between them, even in principle.


So we have these diagrams and thought processes developed from individuals like Jacob D. Bekenstein to help us visualize what is taking place. Gives us key indicators of the valuation needed, in order to determine what maths are going to be used? In this case the subject of Conformal Filed Theory makes itself known, for the thought process to hone in on what is going to be spoken too?

Holography encodes the information in a region of space onto a surface one dimension lower. It sees to be the property of gravity, as is shown by the fact that the area of th event horizon measures the number of internal states of a blackhole, holography would be a one-to-one correspondence between states in our four dimensional world and states in higher dimensions. From a positivist viewpoint, one cannot distinguish which description is more fundamental.Pg 198, The Universe in Nutshell, by Stephen Hawking


So we are given the label in which to speak about the holographical ntions of what is being talked about in the case of the blackhole's horizon.


Campbell's Soup Can by Andy Warhol Exhibited in New York (USA), Leo Castelli Gallery


While it is difficult of such images to be found displayed in the bloggery here to show what Dr. Gary Horowitz is saying you get the jest when you go right to the image of the tomato soup can.

Spacetime in String Theory-Dr. Gary Horowitz, UCSB-Apr 20, 2005

This year marks the hundredth anniversary of Einstein's "miraculous year", 1905, when he formulated special relativity, and explained the origin of the black body spectrum and Brownian motion. In honor of this occasion, I will describe the modern view of spacetime. After reviewing the properties of spacetime in general relativity, I will provide an overview of the nature of spacetime emerging from string theory. This is radically different from relativity. At a perturbative level, the spacetime metric appears as ``coupling constants" in a two-dimensional quantum field theory. Nonperturbatively (with certain boundary conditions), spacetime is not fundamental but must be reconstructed from a holographic, dual theory. I will conclude with some recent ideas about the big bang arising from string theory.


Imagine containing everything we know in this can. Yet,we find that the "soup image" has somehow been translated to other factors and values that seem beyond what we know is real. Is real within the confines and boundaries, and is not evidence of the "infinities" that arise from such non containment?

So, what of the "dilation field" that accumulates, as we speak to what the photon is in the measure of Glast. High energy photon determinations that may also be the valuation of the graviton in expression, as the photon travels through these fields?

Such unification is important once we move into the bulk perspective and what we see of the 2d image of the brane, as a value, and discernation of the label of the soup can?


The ALICE TPC in its clean room, where it is undergoing commissioning of all its sectors.

One of the first cosmic-ray events recorded and reconstructed in two sectors of the TPC.
The tests use the ALICE cosmic muon trigger detector ACORDE, as well as a specially designed UV laser system, to produce tracks in the detector. Preliminary analysis of the cosmic-ray events and the laser-induced tracks indicate that the drift velocity and diffusion of electrons liberated by traversing charged particles, as well as the spatial resolution, are very close to the design values.


So here we are then, having graduated in perspective about what is real, as one may ask the sociological aspect of this whole adventure?



If such missing energy is, "not accounted for" then what happens to the graviton as it is produced and causes energy to travel with them?

For example, people found that a certain vibrational state of the string has zero mass and spin 2. According to Einstein's theory of gravity, the gravitational force is mediated by a particle with zero mass and spin 2. So string theory is, among many other things, a theory of gravity!

Lisa Randall on Xtra Dimensions

In physics, Randall-Sundrum models imagine that the real world is a higher-dimensional Universe described by warped geometry. More concretely, our Universe is a five-dimensional anti de Sitter space and the elementary particles except for the graviton are localized on a (3 + 1)-dimensional brane or branes.

The models were proposed in 1999 by Lisa Randall and Raman Sundrum while studying technicolor models.



With the online chat yesterday I'll have to look in on Sabine Hossenfelder and Stefan's of Backreaction blog entry in this regard to look at it more in depth.

So you intuitively believe higher dimensions really exist?

I don't see why they shouldn't. In the history of physics, every time we've looked beyond the scales and energies we were familiar with, we've found things that we wouldn't have thought were there. You look inside the atom and eventually you discover quarks. Who would have thought that? It's hubris to think that the way we see things is everything there is.

If there are more than three dimensions out there, how does that change our picture of the universe?


The very ideas are of extra dimensions are very progressive, and are not without some history. Some people will label anything as crackpot, without understanding the history of these discussions."




Physics strings us along by Margaret Wertheim of LAtimes.com

In the latest, hottest Big Science tome — the delightfully titled "Warped Passages" — Harvard physicist Lisa Randall describes the idea that the universe we see around us is but one tiny part of a vast reality that may include an infinite number of other universes. Randall is an expert on both cosmology and that arcane branch of particle physics known as string theory. By marrying the two fields, she and her colleagues have formulated a picture in which our universe may be seen as a soap-film-like membrane (a "braneworld") sitting inside a much larger space: the bulk. According to general relativity, the universe we live in has four dimensions: three of space and one of time. Randall's work extends this framework and posits the existence of a fifth dimension. The fifth dimension is the bulk, and within its immeasurably expanded space, there is no reason to assume that ours is the only cosmos.

The Cosmic Connection to Climate


Cars and industrial activity contribute to the 7 gigatons of carbon dioxide released each year into the atmosphere.Credits: EuroNews

Some thoughts about this were being contemplates as I was slowly awaking this morning. I was actually thinking of one more image about seeing Gr being measured by how Grace is looking at and being used to look at the planet in other ways as well.



I'll add that later.

Variation of Cosmic ray flux and Global cloud coverage by Henri Svensmark and Eigil Friis-Christensen, 26 NOvember 1996

Some historical perspective about eight years ago below here raises question about what this cosmic connection might mean from a wider perspective.

CERN plans global-warming experiment(1998)

A controversial theory proposing that cosmic rays are responsible for global warming is to be put to the test at CERN, the European laboratory for particle physics. Put forward two years ago by two Danish scientists, Henrik Svensmark and Eigil Friis-Christensen, the theory suggests that it is changes in the Sun's magnetic field, and not the emission of greenhouse gases, that has led to recent rises in global temperatures.

Experimentalists at CERN will use a cloud chamber to mimic the Earth's atmosphere in order to try and determine whether cloud formation is influenced by solar activity. According to the Danish theory, charged particles from the Sun deflect galactic cosmic rays (streams of high-energy particles from outer space) that would otherwise have ionized the Earth's lower atmosphere and formed clouds.


Looking at this places some extra thinking about what could be taking place in the cosmos, effectively creating the circumstance "also" for changes with regard to earth's climate?



At what point would such intensity of the event in the cosmos cause the larger scenario to be played out, that it also, may have been a contributing factor to what we think about global warming here?



See this link here for further thoughts about the increase in the "lighthouse effect" and how such intensities may be considered in light of the following thoughts being demonstrated here.


This is not to dissuade people from thinking about the current considerations that are man made but raised questions in my mind about the consequences of other factors which may or may not be contributing to global climate changes.

A missing link in climate theory

The Danish National Space Center (DNSC) is a research center under the Ministry of Science, Technology and Innovation. The research activities include astrophysics, solar system physics, geodesy and space technology.
The experimental results lend strong empirical support to the theory proposed a decade ago by Henrik Svensmark and Eigil Friis-Christensen that cosmic rays influence Earth’s climate through their effect on cloud formation. The original theory rested on data showing a strong correlation between variation in the intensity of cosmic radiation penetrating the atmosphere and the amount of low-altitude clouds. Cloud cover increases when the intensity of cosmic rays grows and decreases when the intensity declines.

It is known that low-altitude clouds have an overall cooling effect on the Earth’s surface. Hence, variations in cloud cover caused by cosmic rays can change the surface temperature. The existence of such a cosmic connection to Earth’s climate might thus help to explain past and present variations in Earth’s climate.

Interestingly, during the 20th Century, the Sun’s magnetic field which shields Earth from cosmic rays more than doubled, thereby reducing the average influx of cosmic rays. The resulting reduction in cloudiness, especially of low-altitude clouds, may be a significant factor in the global warming Earth has undergone during the last century. However, until now, there has been no experimental evidence of how the causal mechanism linking cosmic rays and cloud formation may work.

‘Many climate scientists have considered the linkages from cosmic rays to clouds to climate as unproven,’ comments Eigil Friis-Christensen, who is now Director of the Danish National Space Center. ‘Some said there was no conceivable way in which cosmic rays could influence cloud cover. The SKY experiment now shows how they do so, and should help to put the cosmic-ray connection firmly onto the agenda of international climate research.’

Back to the Beginning of Time



While some of us who had been engaged in a little prehistory examination of earliest QGP states as glast determination of high energy photons, the question, "to Be or not to be," how could we not ask what Professor Susskind offered up for examination under the title, "the elephant and the event horizon?"

What happens when you throw an elephant into a black hole? It sounds like a bad joke, but it's a question that has been weighing heavily on Leonard Susskind's mind. Susskind, a physicist at Stanford University in California, has been trying to save that elephant for decades. He has finally found a way to do it, but the consequences shake the foundations of what we thought we knew about space and time. If his calculations are correct, the elephant must be in more than one place at the same time.


I think there is still this far reaching philosophical question about what really started time? If "nothing" existed then how could we assume anything could arise from it?

While empirically Aristotle has lead the thinking, you know how I think don’t you:) Do you see me stand apart from Aristotle?




So I resolve this question in my own mind, even if I do refer to Gabriele Veneziano and his introduction of what began as string theory.

How could I resolve "anything" that has been taken down to the very first microseconds, while recognizing the value of anything "underneath the guise of building blocks of matter," and have said, "that this is the theory of everything?"

It only helped us to the point of the singularity, but it is much different then a complete death. The whole time reductionistic thinking has dominated the move back in history, there were other things going on, that us simple lay people were not aware of. Maybe for some scientists too?:)


Colliding galaxies, NGC 4676, known as "The Mice" (credit: Credit: NASA, H. Ford (JHU), G. Illingworth (UCSC/LO), M.Clampin (STScI), G. Hartig (STScI), the ACS Science Team, and ESA )
The James Webb Space Telescope (JWST) is a large, infrared-optimized space telescope, scheduled for launch in 2013. JWST will find the first galaxies that formed in the early Universe, connecting the Big Bang to our own Milky Way Galaxy. JWST will peer through dusty clouds to see stars forming planetary systems, connecting the Milky Way to our own Solar System. JWST's instruments will be designed to work primarily in the infrared range of the electromagnetic spectrum, with some capability in the visible range.

JWST will have a large mirror, 6.5 meters (21.3 feet) in diameter and a sunshield the size of a tennis court. Both the mirror and sunshade won't fit onto the rocket fully open, so both will fold up and open only once JWST is in outer space. JWST will reside in an orbit about 1.5 million km (1 million miles) from the Earth.

JWST Science

The JWST science goals are divided into four themes. The key objective of The End of the Dark Ages: First Light and Reionization theme is to identify the first luminous sources to form and to determine the ionization history of the early universe. The key objective of The Assembly of Galaxies theme is to determine how galaxies and the dark matter, gas, stars, metals, morphological structures, and active nuclei within them evolved from the epoch of reionization to the present day. The key objective of The Birth of Stars and Protoplanetary Systems theme is to unravel the birth and early evolution of stars, from infall on to dust-enshrouded protostars to the genesis of planetary systems. The key objective of The Planetary Systems and the Origins of Life theme is to determine the physical and chemical properties of planetary systems including our own, and investigate the potential for the origins of life in those systems.


So again, we are being lead by science here to look ahead to what plans for the future may have influenced, or caused the decsisons they did, on another trip to refurbish the Hubble Space Telescope?

The Dark Ages of the UniverseBy Abraham Loeb

What makes modern cosmology an empirical science is that we are literally able to peer into the past. When you look at your image reflected off a mirror one meter away, you see the way you looked six nanoseconds ago--the light's travel time to the mirror and back. Similarly, cosmologists do not need to guess how the universe evolved; we can watch its history through telescopes. Because the universe appears to be statistically identical in every direction, what we see billions of light-years away is probably a fair representation of what our own patch of space looked like billions of years ago.


So then I am at a loss to explain that what happened billions of years ago near the beginning of this universe, could have ever been created in this universe now? Some body may say to you, "that the beginning of time and the distance of the beginning of the universe to now, has no correlation?"

If the circumstance are to be created in our colliders, then what said that mass determinations will ever arise from our research into the HiGG's, is not relevant, to what can be created in this space and time now?

Remember, everywhere you look in the cosmos this possibility exists. The WMAP is indictive of what I am saying.

So you say, the beginning of the universe and "the time created" to produce the particles of new physics, has no correlation into how this universe came into being?

Perhaps you may like to read Stephen Hawkings perspective on the beginning of time?

The conclusion of this lecture is that the universe has not existed forever. Rather, the universe, and time itself, had a beginning in the Big Bang, about 15 billion years ago. The beginning of real time, would have been a singularity, at which the laws of physics would have broken down. Nevertheless, the way the universe began would have been determined by the laws of physics, if the universe satisfied the no boundary condition. This says that in the imaginary time direction, space-time is finite in extent, but doesn't have any boundary or edge. The predictions of the no boundary proposal seem to agree with observation. The no boundary hypothesis also predicts that the universe will eventually collapse again. However, the contracting phase, will not have the opposite arrow of time, to the expanding phase. So we will keep on getting older, and we won't return to our youth. Because time is not going to go backwards, I think I better stop now.

The Higg's Boson and Memory?

While some like chocolate bars and the bubble nature of candy, some also like the molasses and ice cream? :)


If Plato Had thought "the new born" was not really such a "blank slate" then what did he mean exactly? If we could remember, "in what form" would these memories have manifested?

The origins of thought would have found that what existed before, had to make it's way into what we are doing today? So is it really "lost" since we cannot and do not remember what was before? Or, is it possible to remember?

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


So how does this lump of clay ever take with it all that was before. Is it just a slight shift in our tonal? What was "not apparent before" is now very much a a part of our views of nature now. Before, it was "very pleasing," and now, it is "still very pleasing" that our cosmological views have been extended some how? :)

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.


Of course we always look for directions as to which way we'll have to look for things to understand just what our perceptions reveal and what is the basis for our thoughts as to the nature of the universe?

For example, theory says that Higgs particles are matter particles, but in most respects the Higgs behaves more like a new force than like a particle. How can this be? In truth, the Higgs is neither matter nor force; the Higgs is just different.


So it is never easy for me to follow from one thought to the next.

Imagine, the "molasses" here for a minute. What gives mass it's shape while we cannot discern the very beginning as an asymmetrical valuation? Based on the notion, that there was a simpler time entropically, how do we know what is discretely measured?

Why the discrete measure and it's shape?



New measurements of top quark mass at Fermilab have revised estimates for the mass of the Higgs boson.
Scientists believe that the Higgs boson, named for Scottish physicist Peter Higgs, who first theorized its existence in 1964, is responsible for particle mass, the amount of matter in a particle. According to the theory, a particle acquires mass through its interaction with the Higgs field, which is believed to pervade all of space and has been compared to molasses that sticks to any particle rolling through it. The Higgs field would be carried by Higgs bosons, just as the electromagnetic field is carried by photons.

"In the Standard Model, the Higgs boson mass is correlated with top quark mass," says Madaras, "so an improved measurement of the top quark mass gives more information about the possible value of the Higgs boson mass."

According to the Standard Model, at the beginning of the universe there were six different types of quarks. Top quarks exist only for an instant before decaying into a bottom quark and a W boson, which means those created at the birth of the universe are long gone. However, at Fermilab's Tevatron, the most powerful collider in the world, collisions between billions of protons and antiprotons yield an occasional top quark. Despite their brief appearances, these top quarks can be detected and characterized by the D-Zero and CDF experiments.


So yes there are these experiments that lead us to think about how the universe came into being? All these things that we see in the universe, are they so very different from every other point in space. How is it's particle nature revealed and we have gained much from discerning the quantum dynamically nature of what, "just is."

What just "is?"

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.


I mean it's vague to me that such a memory could have been transferred to other things. The Universe has become very large, and entropically complex? Our universe of discrete things, have become complex in discretized values. How would we have ever seen the "purity of thought manifest" if we did not delve ever deeper into the nature of things?

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.

The Radius of the Little Circle

Where a dictionary proceeds in a circular manner, defining a word by reference to another, the basic concepts of mathematics are infinitely closer to an indecomposable element", a kind of elementary particle" of thought with a minimal amount of ambiguity in their definition. Alain Connes


With such a statement, the "purity of thought," is speaking to a much more schematic understanding as we discuss the sociological thinking of mathematicians and the worlds they fantasize about? While deeper in reality the thought process(meditative) was engaged at a very subtle level, associated with the energy all pervasive.




Lee Smolin :
Another wonderful spin-off is that it turns out that the charge of the electron is related to the radius of the little circle. This should not be surprizing: If the electric field is just a manifestation of geometry, the electric charge should be, too.
THE TROUBLE WITH PHYSICS-Published by Houghton-Mifflin, Sep. 2006/Penguin (UK), Feb. 2007, Page 46


In "Star Shine," we start from a very large circle, but there is much to see from this circle, when we consider it's radius. We think "continuity" is somehow not involved, if we freeze this circle, and call it a discrete measure of the universe's age? Yet we know to well that the motivation of this universe from a "distant point" measure today entropically lives in the multitude of complexities?

Plato:
Model apprehension is part of the convergence that Lee Smolin and Brian Greene talk about, and without it, how could we look at nature and never consider that Einstein's world is a much more dynamical one then we had first learned from the lessons GR supplied, about gravity in our world?


On page 47 of the Trouble with Physics Lee goes on to say further down the page:

Lee Smolin:
Unfortunately, Einstein and the other enthusiasts were wrong. As with Nordstrom's theory, the idea of unification by adding a hidden dimension failed. It is important to understand why.


If all one had was the "cosmological view" one could be very happy about the way in which his observations have been deduced from the measures of our mechanical means, that we say that GR is very well suited.

Yet it has been through th efforts of reductionism that we have said, "hey there is indeed more depth to the views we have, that the mechanical measures are being tuned accordingly?"



Juan Maldacena:
The strings move in a five-dimensional curved space-time with a boundary. The boundary corresponds to the usual four dimensions, and the fifth dimension describes the motion away from this boundary into the interior of the curved space-time. In this five-dimensional space-time, there is a strong gravitational field pulling objects away from the boundary, and as a result time flows more slowly far away from the boundary than close to it. This also implies that an object that has a fixed proper size in the interior can appear to have a different size when viewed from the boundary (Fig. 1). Strings existing in the five-dimensional space-time can even look point-like when they are close to the boundary. Polchinski and Strassler1 show that when an energetic four-dimensional particle (such as an electron) is scattered from these strings (describing protons), the main contribution comes from a string that is close to the boundary and it is therefore seen as a point-like object. So a string-like interpretation of a proton is not at odds with the observation that there are point-like objects inside it.


While energy is being exemplified according to the nature of the particles we see in calorimetric design, what said that the energy here is not topologically smooth in it's orientations? Even we we move our views to the quantum regime.

Maybe having solved the "Continuum Hypothesis," we learned much about Einstein's inclinations?

The surface of a marble table is spread out in front of me. I can get from any one point on this table to any other point by passing continuously from one point to a "neighboring" one, and repeating this process a (large) number of times, or, in other words, by going from point to point without executing "jumps." I am sure the reader will appreciate with sufficient clearness what I mean here by "neighbouring" and by "jumps" (if he is not too pedantic). We express this property of the surface by describing the latter as a continuum.Albert Einstein p. 83 of his Relativity: The Special and the General Theory



Even Einstein had to add the "extra dimension" so we understood what non-euclidean views meant in a geometrical sense. I again refer here to Klein's Ordering of Geometries so one understands the schematics and evolution of that geometry.

Doppelgänger Favors Oscillate

"Observations always involve theory."Edwin Hubble


Of course I relate the "Ghost Particle to Pauli" here so that people would recognize the faint discerning image in "mirror world," as some calculation that paved the way for some future spoken from Feynman's point of view, to John Bahcall. Imagine what began as a theory/concept/idea, could have brought on this whole subject of neutrinos.

Of course here I could relate the story of "Alice in Wonderland" and Ivars Peterson may have some thoguhts on this as well. About fantasy, and what a good mathematcian should have in her/his arsenal for future prospects which will manifest as Nikolai Lobachevsky relates in quote below.

So the idea here is of course that we are looking at the neutrinos as a mechanism responsible for the matter/anti-matter asymmetry. But hold this thought while we continue through here at the unimaginable, to the manageable in testing theory.

There is no branch of mathematics, however abstract, which may not some day be applied to phenomena of the real world.Nikolai Lobachevsky


I couldn't help but think of the new TV series "Heroes" that is now playing. Of course there are intriguing ideas here about time travel, regeneration, and what do you know, the "Doppelgänger," of mirror world.

Niki Sanders, a 33-year-old Las Vegas showgirl who can do incredible things with mirrors


Well under that pretense the idea is one of the dark side being show in mirror world, while the unconsicous stae of mind is somehow dropped in place of it's dark resurgence? How do you ever calculate something like that? Imagine, "Angels and Demons" as some sphere related by Escher as the revolving sphere of understanding?

A doppelgänger (pronunciation (help·info)) is the ghostly double of a living person. The word doppelgänger is a loanword from German, written there (as any noun) with an initial capital letter Doppelgänger, composed from doppel, meaning "double", and gänger, as "walker". In English, the word is conventionally not capitalized, and it is also common to drop the German diacritic umlaut on the letter "a" and write "doppelganger", although the correct spelling without umlaut would be "doppelgaenger".


Right Handed Neutrino

Anyway there is this idea/concept/theory that refers to the combining gravity with the other forces. They call this supersymmetry. This requires that each particle to have a supermassive shadow particle?

Like many detectors, this experiment at the Fermi National Accelerator in Batavia, Illinois investigates the oscillation of neutrinos from one type to another. Since 2003, it has observed neutrinos created from protons in Fermilab's particle booster, part of the system that the lab normally employs to accelerate protons to higher energies for other experiments. MiniBooNE is a 40-foot-in-diameter spherical steel tank filled with 800 tons of mineral oil and lined with 1,280 phototubes (some of which are being adjusted in this image) that produce a flash of light when charged particles travel through them. Analyses of these light flashes are already providing tantalizing information


So if the assumption is that the "sterile neutrino" could roam in higher dimensions being undetected by us, and make it's presence felt through the influence of gravity, what does this say about grvaity currently measure at this time in the universe?

Might it mean that when only measuring high energy collidial events, that we have within the presence of the cosmo, also the the effect of weak grvaitation measures allotted to the sterile neutino, then what does this say to us about the extension of the standard model as new physics?

Current evidence shows that neutrinos do oscillate, which indicates that neutrinos do have mass. The Los Alamos data revealed a muon anti-neutrino cross over to an electron neutrino. This type of oscillation is difficult to explain using only the three known types of neutrinos. Therefore, there might be a fourth neutrino, which is currently being called a "sterile" neutrino, which interacts more weakly than the other three neutrinos.

BooNE will determine the oscillation parameters and possibly yield further information about the mass of a neutrino

    A new LHC experiment is born!

    The LHC experiments are mostly on a very grand scale, with huge detectors and collaborations of as many as 2000 people; however, LHCf, like TOTEM, is quite special. The detectors are much smaller and LHCf has an equally small collaboration of just 22 people. The collaboration led by Yasushi Muraki, with members from Japan, Italy and the US, has just finished testing its detectors.

    The focus of the experiment is to study the forward moving particles in the proton-proton collisions at the LHC. This will be used to compare the various shower models widely used to estimate the primary energy of ultra high-energy cosmic rays, with energy in the region of 1019 eV (10 billion billion electronvolts). When the proton-proton collisions occur at the LHC pions are produced just as in a cosmic ray air shower. The amount of these secondary particles produced at the LHC can be measured accurately with the LHCf detectors, since the energy and direction of the primary beam is well known. The data will then be compared with the models used by the cosmic ray community.

    Although discovered as long ago as 1912 by the Austrian physicist, Victor Hess, cosmic rays remain mysterious. In particular, physicists would like to know more about the origins of the very high energy cosmic rays, up to 1020 eV that have been observed during recent decades. Some important experiments, such as the Pierre Auger Cosmic Ray Observatory in Argentina (See CERN Courier, July/August 2006), the Telescope Array experiment in the US and the HESS experiment in Namibia are dedicated to this research (See CERN Courier, February 2005). The LHCf experiment aims to give some valuable data to input into these studies; many of the physicists participating in LHCf are also involved in these and other projects related to cosmic rays.

    The detectors of LHCf will be placed on either side at 140 m from the ATLAS interaction point. This location will allow for observation of particles at nearly zero degrees to the proton beam direction. The detectors consist of two towers of sampling calorimeters designed by Katsuaki Kasahara from the Shibaura Institute of Technology. Each of them is made of tungsten plates and plastic scintillators of 3 mm thickness for sampling.

    Many of the physicists from LHCf have reunited from the former SPS experiment UA7, which also focused on forward physics. The LHCf experiment will be simulating cosmic ray collisions nearly 1000 times more energetic than UA7 was able to access. The energy of proton collisions in the LHC will be equivalent to a cosmic ray of 1017 eV smashing into the atmosphere. Therefore, LHCf will use the LHC beams to test the interaction models of cosmic rays to higher accuracy.

    Did you know?

    Cosmic rays are charged particles, mainly protons, but also alpha particles (helium nuclei) or heavier nuclei that bombard the Earth's atmosphere from outer space. These nuclei collide with the nuclei in the upper atmosphere producing many secondary particles, which in turn collide with other nuclei in the lower atmosphere. This process continues in a cascade, producing a shower of billions of particles reaching the ground.

    Cosmic rays show a wide range of energy. The low energy cosmic rays are plentiful (many thousand per square metre every second), many of which come from the sun. The highest energy cosmic rays, up to 1020 electronvolts, are very rare, arriving at a rate of one per square kilometre per century! The source of ultra high energy cosmic rays remains a mystery, as the primary ray seems to come from all directions.


    This, when we had thought science was at an end?

    Part of Facing the Trouble With Physics

    It might be that the laws change absolutely with time; that gravity for instance varies with time and that this inverse square law has a strength which depends on how long it is since the beginning of time. In other words, it's possible that in the future we'll have more understanding of everything and physics may be completed by some kind of statement of how things started which are external to the laws of physics. Richard Feynman


    Faced with the task of showing the connection between string theory and reductionistic consideration is quite a task, as I am sure in most eyes? To me it just seems that everytime we adjust our view and include new views, what shall we say of "gamma ray detection" when we look at high energy photons describing the early universe for us?



    Hey, it makes my heart jump too.

    Here is a case, with which I like to make my point. Having someone corrected makes it that much better now to make comparisons like I do. The simple point of "order" enlightened greatly the situation for us, in what I am exemplifying here. We wil not forget the paper offered up after, in that comment thread either. Thanks

    A realization 1; 2; 3 that QGP at RHIC is not a weakly coupled gas but rather a strongly coupled liquid has lead to a paradigm shift in the field. It was extensively debated at the “discovery” BNL workshop in 2004 4 (at which the abbreviation sQGP was established) and multiple other meetings since.

    In the intervening three years we had to learn a lot, some new some from other ranches of physics which happened to have some experience with strongly coupled systems. Those range from quantum gases to classical plasmas to string theory. In short, there seem to be not one but actually two difficult issues we are facing. One is to understand why QGP at T ∼ 2Tc is strongly coupled, and what exactly it means.


    In Extracting Beauty From Chaos I am recognizing this depth of perception enhancement that is supplied by JoAnne of Cosmic Variance. Would you rather look at "Seans moon" in gamma?

    CERN planned a global-warming experiment in 1998?

    Experimentalists at CERN will use a cloud chamber to mimic the Earth's atmosphere in order to try and determine whether cloud formation is influenced by solar activity. According to the Danish theory, charged particles from the Sun deflect galactic cosmic rays (streams of high-energy particles from outer space) that would otherwise have ionized the Earth's lower atmosphere and formed clouds.



    What shall I say to you as SNO investigated the "cerenkov effect" from the cosmos ray particle collisions? Shall I speak about the "weather predictions" that arise. This is a interference and a "weak measure" of what is fast becoming the thought in my mind of the diversity of global painting, to include, that blue light as each of the detectors "pick" the overall pattern of high energy exchanges in the detectors as inherent image understanding. It has been transcribed from the "sun's energy value" and applied to high energy considerations?

    "Atmospheric" neutrinos, produced by interactions of cosmic ray particles with the earth's atmosphere, might be useful for studying the properties of neutrinos. But if you're hunting sources of neutrinos in the universe, atmospheric neutrinos are nothing but noise.



    Now, I may reference Glast indications here in the experimental validation of those high energy photons, gamma ray indication is a wonderful jesture to extending the depth of perception, as I have tried to do here by helping Q see the relevance of the quantum dynamical perception. From ,the beginning of this universe.

    So we see where the " Window of the universe" has helped me to see in ways that we were not accustomed. It is "the physics" that has taken us there.

    So, while the picture of JoAnnes is highlighted, the lesser of the views is the "gamma ray detection" while I have pointed to the neutrino here in experimentation.

    Should we loose sight of what the KK tower exemplifies?



    I am sorry about the "dead link picture to topology" but blogger does not go back to 2004 so that I can adjust it.

    Now why would I then reference "quantum gravity" behind the picture of the KK tower, and the information about topology? Possibly, that we have for the first time thought here that the Navier-Stokes equations could have been applied at a fundamental level while thinking of what the QGP has given us, as we witness "cerenkov radiation" from a long line of reductionistic reasoning? Is this worth a million from the Clay Instituted by generalization alone?:)

    If not, at least, if held in line with lagrangian views of gravitonic perceptions in the bulk as we phyically see the relation between the sun and earth?

    It is thus my mind has been held to the idea of the "conical flows[Volcanos, to jet engines in analogy of the laval nozzle]" as the energy is released for the dissemmination from the collider of nature enhanced, to all that follows from the cosmic particle interactions. Right to the neutrinos resulting from the fluidity of the QGP pertaining to viscosity?

    What was not present before? Muon detectors hmmmm..... and the road from muon neutrinos too?? What am I missing here?

    The muons are stopped by the rock. Impervious to all such obstacles, the muon neutrinos will leave the CERN tunnels and streak through the rock on their 732 kilometre journey to Italy.


    Hold that picture of JoAnnes, while you think of Glast. In the determinates of the gamma ray detection, we have therefor faced the "Trouble with Physics?":)

    "Lead by Physics," Faces the "Trouble With Physics"


    The Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory is a world-class scientific research facility that began operation in 2000, following 10 years of development and construction. Hundreds of physicists from around the world use RHIC to study what the universe may have looked like in the first few moments after its creation. RHIC drives two intersecting beams of gold ions head-on, in a subatomic collision. What physicists learn from these collisions may help us understand more about why the physical world works the way it does, from the smallest subatomic particles, to the largest stars



    Well I have to deal with first things first here. This article above correlates the one given by Stefan. This is not to contest what you are saying, just to show you the informtaion I myself had gone through to arrive at the conclusions I do.

    Ion-Smashing Yields New Knowledge, But Some Still Question Risk
    By Carolyn Weaver

    Seen from above, the Relativistic Heavy Ion Collider, or RHIC, at New York’s Brookhaven National Laboratory, looks like a racetrack. And it is a kind of race track: two “beam pipes” in a tunnel nearly four kilometers around, in which gold nuclei are accelerated to close to the speed of light, and are crashed into each other at intersecting points along the way. Out of the kinetic energy of those collisions, new matter is created for a brief instant: a shower of quarks and gluons, the smallest particles known – and at seven trillion degrees, hotter than anything now in the universe.



    Brookhaven physicist Peter Steinberg
    “It’s basically a living embodiment of E=mc squared,” says Brookhaven physicist Peter Steinberg. “Einstein’s theory told us a hundred years ago that you can trade off energy for mass, and vice versa. We’re essentially converting the kinetic energy, the energy from the motion of these nuclei, converting it into lots of particles.”

    The four detectors that bestride the collision points are massive machines, with “time projection chambers” that record the collisions and their after-moments. The latest results made big news last year when Brookhaven physicists reported that the quark-gluon plasma was not a gas as expected, but rather a very dense liquid.


    You say strangelets do not exist? And that no connection has been found between string theory, and strangelets. I have to then argue my case so you see it in light of what the reductionistic physics is actually doing, while string theory and it's energy values hover overhead of all these interactions. How th epaticle inclination must also include microstate blackhole creation.

    So bear with me if you can.


    Hi Plato,

    strange matter and strangelets are a very interesting topic, but, unfortunately, there has been no experimental evidence for them so far. They are not really connected to string theory either, besides the fact that it was an early paper of Witten that resuscitated interest in them with nuclear physicists, I think.

    Strangelets have been thought of as possible culprits for RHIC disaster scenarios (besides the ubiquitous black holes ;-), and as responsible for potential cosmic ray particles beyond the GZK cutoff.

    But as far as I know, there has been no experimental verification of any of these ideas (and the world still exists: RHIC has produced no greedy strangelets which would have eaten up the Earth).

    In the case of the potential quark star you cite, RX J185635-375, again, and unfortunately, as far as I remember, it came out that the radius determination was not completely safe. Bottomline was that this star could be well understood as a common neutron star. I am not completely sure, though, about the current status of this object, whether it is thought to be a quark star or not.

    Anyway, it is a good example for an exciting observation which is reported in the press, but which has to be partially revisd later - only that these revisions don't make in the press releases. I guess it would often be quite interesting to have a kind of follow-up reporting, where one could read what is, eventually, the fate of some discovery that has been announced in the press.

    The strange particles I was talking about are not strangelets, but the common hadrons with strangeness, especially the Ξs and the Ωs, with two and three strange quarks, respectively. These are the particles that I had mentioned in my earlier post, and whereof I should finish the second part, finally ;-). You typically find much more of these particles in nucleus-nucleus collisions than in (properly scaled) nucleon-nucleus collisions, which is a strong indication for an intermediate QGP state, where stange-antistrang quark pairs can easily be produced.

    Best, stefan



    One, as we know can make wide sweeping generalization about the physics and why is it that any position taken by any scientist would not have been one that becomes the point of departure for all scientists? An example her ei the rationship to the Heavy Ion collsions an dstringtheory and by this very nature to the strangelets as postulated.

    This article below is to correlate with the article you showed me of 2004, while I had made this ocnlusion myself early in 2006, lets not forget the number of people involved in the "ghost particle, and Pauli" through out the years and what we have seen theoretically of the strangelets as they had been related to the disaster scenario as consequential microstate blackholes created in the RHIC and LHC.

    Is this too drastic a scenario to have you think about what all these “particles in press” are saying about the science, that any one scientist themselves might be following to correct? You say, "just get it right?" Well there are many within the blogs who are writers for those articles? Why do you think they are amongst you?

    I had noticed the grouping and conversations between blogs that had been developing over the last year and half. I continue to see some of the same people. Some, that constantly referred to the reporting that goes on. So I had to address this or forever be banished to the realm of reporting as someone just profiled.

    Strangelet Search at RHIC by STAR Collaboration

    Three models of strangelet production in high-energy heavy-ion collisions have been proposed in the 1980s and 1990s: coalescence [10], thermal statistical production [11], and distillation from a Quark Gluon Plasma (QGP) [12, 13]. The first two models usually predict low strangelet production cross sections at mid-rapidity, as verified by measurements of the related processes of coalescence of nucleons into nuclei [14]. If a QGP is created in heavy ion collisions, it could cool down by distillation (kaon emission) and condense to strange-quark-rich matter in its ground state – a strangelet. However, this requires a net baryon excess and a non-explosive process in the collisions [12, 15]. Neither of these conditions is
    favored at mid-rapidity in ultra-high energy heavy ion collisions, as suggested by results from the Relativistic Heavy Ion Collider (RHIC) at BNL [16]. Recently a new mechanism for strangelet


    I want you to have a good look at the number of names listed in this Pdf file as well the universities involve.

    Clifford of Asymptotia made this point clear about the vast network of scientists even within the string theory network of people and about who knows whom? Can you possibly know everyone, or, like the paper whose citations are referred to more as we refer to any particular scientist? We then come to see the make up and nature as we hold our views to the particular few.

    So before I begin here I wanted to make it clear, that having spent considerable time as hobby and interest about science. It is not without my own motivations that the interest would be the memory of one’s childhood, or the magazine that we looked at, but the reality we are dealing with and what we call the “nature of things.”

    An anomaly that cannot be explained nor shall it be removed because of the lack of evidence. It’s just one of those things that you cannot change in the person’s make up who has seen the world in a different way then normal. So shall he endeavor to accumulate all the things that are wrong to destabilization the view of truth of the world just so he can corrupt all those around him?

    I ask myself the question about "what is natural" because I seen what scientists were doing to each other about the theoretical/concepts/ideas models that they were adopting in their research, that I wanted to make sure that what I had been researching had been as up to date.

    Would one "leave out information that I had assembled" as they deal with me?

    As I have said before while the students have been engaged in the classroom I had been following the physics development as best I could. Spent years watching and learning

    So here's the thing.

    If I did not answer Stefan at Backreaction about the information about strangelets then it might have been left off where Stefan decided too as he continues to show his elementary particle thinking( finish the second part Stefan).

    Continued reference to strangelets might everyone think the conclusion as written I the way Stefan has shown it? Would information I had been developing have been less than the standard of what scientists hold as standard. How could anyone know it all? Hold the badge over the trial of LHC or RHIC and say I had broken the law with my insolence and corruptible behavior?:) Non! Qui?

    So here again is the conundrum I had placed in front of me as I looked and interacted with the various blogs who have commented on Lee Smolin’s book, “The trouble With Physics.”

    But first let me then deal with Stefan at Backreaction.

    Lubos Motl:
    Well, I think that even if someone believes that theoretical physics can't be trusted - and many people clearly do - there exists a less scientific argument why the accelerator won't lead to such a catastrophe: the Earth is bombed by a lot of very high-energy cosmic rays and the center-of-mass energy of the collisions is comparable to the LHC energies. So far, these collisions haven't destroyed the Earth, so it is reasonable that some additional collisions we create won't be able to do so either.


    While I had these similar thoughts it was not wothpt some basis the Blogett would have pointe dyou to think about strnagelets and then in my own assumptions, the comic particle collsions from what Ellis had taught us to think about. Yes, it was the natural collider in space for sure, and it's "energy values" well beyond what is availiable at LHC.

    So yes "Microstate creation of blackholes in space"

    In strangelets do not exist, I had come to the same conclusion Stefan did about what is "theoretically challenged" might have engaged the thinking mind as to the relationship to what the neutrino may have been in that exercise of the QGP, compared to this one on strangelets.

    So I gathered information to help me see the direction the physics was going. Least it escaped the mantra that I had been hearing exemplified in my dealings as best I can.

    “Lead by the Physics.” Now I face, "the trouble with Physics."

    What is Cerenkov Radiation?

    ...the creative principle resides in mathematics. In a certain sense therefore, I hold it true that pure thought can grasp reality, as the ancients dreamed.Albert Einstein


    Many do not recognize the process that unfolds in the developing perspectives about theoretics? Does one think it is divorced from reality that you could say, "hey this idea of course has no attachment to what exists and what we know exists and asks that you move forward with it."

    Often you hear the "dreaded reference" to the AEther, and who can help but see where such revisions in thinking changed the society of scientists to put them on a new course?

    Do you think the title was changed from the aether to the valuation of strings and the boson production evident in the bulk just to replay itself in the developing scenarios of our historical past? The past included a revision to the way we view that concept? That is it's effect in today's world. "The correction?"

    As we know from Einstein’s theory of special relativity, nothing can travel faster than c, the velocity of light in a vacuum. The speed of the light that we see generally travels with a slower velocity c/n where n is the refractive index of the medium through which we view the light (in air at sea level, n is approximately 1.00029 whereas in water n is 1.33). Highly energetic, charged particles (which are only constrained to travel slower than c) tend to radiate photons when they pass through a medium and, consequently, can suddenly find themselves in the embarrassing position of actually travelling faster than the light they produce!

    The result of this can be illustrated by considering a moving particle which emits pulses of light that expand like ripples on a pond, as shown in the Figure (right). By the time the particle is at the position indicated by the purple spot, the spherical shell of light emitted when the particle was in the blue position will have expanded to the radius indicated by the open blue circle. Likewise, the light emitted when the particle was in the green position will have expanded to the radius indicated by the open green circle, and so on. Notice that these ripples overlap with each other to form an enhanced cone of light indicated by the dotted lines. This is analogous to the idea that leads to a sonic boom when planes such as Concorde travel faster than the speed of sound in air


    But we have to go back in history here to see where such influences have taken hold of the mind, from what was instituted in the neutrino search, to have the ideas swirl around and form new prospect researches, based on the ideas of women/men?



    The story will follow here shortly. I would like to thank Paul on his early recognition of the bubble chamber events as they encourage research in 1998 to ponder the experiments in Cern to say?

    Add your story so that this can be completed. I will add mine for a wonderful view of what research and developement does in regards to the way of "modelling to experiment."

    Well since starting this blog entry there has only been two other examples that may be added to this entry as of today, yet, one by Commentor NC at Cosmic Variance while the other materialized over at Backreaction on the post done by Bee and Stefan.

    A Look Back

    Have a look at this image below first.



    Variation of Cosmic ray flux and Global cloud coverage-a missing link in Solar-climate relationshipsby Henri Svensmark and Eigil Friis-Christensen, 26 NOvember 1996

    So this is wonderful that in one way, where my mind rebukes the lashing out of Peter Woit by evidence of ICECUBe and my ir/relevant comments, could have found sustenance in how things are to be explained further? More physics ...wonderful.

    But I want to go back historically to view, so that one sees what was a picture "written by Paul" and his trip to Canada, held an observation that sends us back in time experimentally to look at, to find out, what Cern was doing in 1998. Thanks Paul

    You ready?

    CERN plans global-warming experiment(1998)

    A controversial theory proposing that cosmic rays are responsible for global warming is to be put to the test at CERN, the European laboratory for particle physics. Put forward two years ago by two Danish scientists, Henrik Svensmark and Eigil Friis-Christensen, the theory suggests that it is changes in the Sun's magnetic field, and not the emission of greenhouse gases, that has led to recent rises in global temperatures.

    Experimentalists at CERN will use a cloud chamber to mimic the Earth's atmosphere in order to try and determine whether cloud formation is influenced by solar activity. According to the Danish theory, charged particles from the Sun deflect galactic cosmic rays (streams of high-energy particles from outer space) that would otherwise have ionized the Earth's lower atmosphere and formed clouds.


    So what is this science based on?

    The production of a high-intensity neutrino beam at CERN requires a complex facility. A proton beam produced and accelerated by the CERN accelerators is directed onto a graphite target to give birth to other particles called pions and kaons. These particles are then fed into a system comprising two magnetic horns which focus them into a parallel beam that is directed towards Gran Sasso. Next, in a 1000 metre-long tunnel, the pions and kaons decay into muons and muon neutrinos. At the end of this decay tunnel, an 18 metre thick block of graphite and metal absorbs the protons, pions and kaons that did not decay. The muons are stopped by the rock. Impervious to all such obstacles, the muon neutrinos will leave the CERN tunnels and streak through the rock on their 732 kilometre journey to Italy.


    Now what does this have to do with Cerenkov radiation? Okay. I'm scratching my head now.

    “CERN has a tradition of neutrino physics stretching back to the early 1960s,” said Dr Aymar, “this new project builds on that tradition, and is set to open a new and exciting phase in our understanding of these elusive particles.”


    From the 1960's. Wow!

    Imagine that someone might say to you that this is a "Rube Goldberg Machine" analogy as to what was the road leading to the understanding and the inclusiveness of microstate blackhole creation from particle collisions, as part of the continued story of the neutrino in action?

    From Modelling to Experimentation?


    Moving to higher energies, the expected fluxes of neutrinos become smaller, that even a cubic kilometer detector is not able to detect them. Larger volumes can be achieved by replacing optical sensors by acoustic detection. The reason is that acoustic waves can propagate over larger distances than light and allow wide spacing of detectors, and therefore larger detector volumes.


    From Modelling to new thoughts on experimental processes and approach to the physics involved, it is important that one understands how this approach is considered. Not to loose sight of the relationship to high energy consideration and it's particle shower effect from such interactions.

    Without some comprehension of RHIC valuation in production uses what was to be gained from cosmic particle collisions? What future in LHC inclusion of microstate with out some association to particle entities as a result of those collisions?

    Reductionist processes leads to comprehension values that if let unnurtured, would not have allowed such model comprehension to exceed current limitation of thinking?

    "String theory and other possibilities can distort the relative numbers of 'down' and 'up' neutrinos," said Jonathan Feng, associate professor in the Department of Physics and Astronomy at UC Irvine. "For example, extra dimensions may cause neutrinos to create microscopic black holes, which instantly evaporate and create spectacular showers of particles in the Earth's atmosphere and in the Antarctic ice cap. This increases the number of 'down' neutrinos detected. At the same time, the creation of black holes causes 'up' neutrinos to be caught in the Earth's crust, reducing the number of 'up' neutrinos. The relative 'up' and 'down' rates provide evidence for distortions in neutrino properties that are predicted by new theories."

    The Periodic Table of the Moon's Strata


    Clementine color ratio composite image of Aristarchus Crater on the Moon. This 42 km diameter crater is located on the corner of the Aristarchus plateau, at 24 N, 47 W. Ejecta from the plateau is visible as the blue material at the upper left (northwest), while material excavated from the Oceanus Procellarum area is the reddish color to the lower right (southeast). The colors in this image can be used to ascertain compositional properties of the materials making up the deep strata of these two regions. (Clementine, USGS slide 11)
    Clementine gravity experiment used measurements of perturbations in the motion of the spacecraft to infer the lunar gravity field


    Like Grace, I choose to build an understanding of the gravity fields.

    S-Band Transponder Doppler Gravity Experiment

    The gravity experiment used measurements of perturbations in the motion of the spacecraft to infer the lunar gravity field. Clementine was equipped with an S-band microwave transponder and 2 S-band omni-directional high-rate antennas which were used for tracking by the NRL tracking station in Pomonkey, MD, and the NASA Deep Space Network. The frequency of the S-band transmission was measured every 10 sec, and the Doppler shift would give the relative velocity of the spacecraft towards or away from the Earth. Accelerations were calculated from changes in the velocity, and after accounting for the orbit, relative motions of Earth and moon, and Earth and solar gravity, these accelerations are converted to lunar gravity effects on the spacecraft.
    The calculated lunar gravity field can be used to model subsurface lunar structure. The Pomonkey station could measure the velocity to an accuracy of 3 mm/sec, while the Deep Space Network stations could achieve about 0.3 mm/sec. Tracking was not possible on most of the lunar far side (120° to 240° long, -45° to 45° lat), when the moon was between the spacecraft and the Earth. In all, over 361,000 observations were made, approximately 57,000 at less than 1000 km altitude.


    As our physical interpretation of this lovely pearl(earth) we live on has changed in the conceptual views of "times clocks and such," it became evident in GRACE that the world was quite different then what was first view from space in triumph.

    As you might well know, all matter in the universe consists of small particles called atoms and each atom contains electrons that circle around a nucleus. This is how the world is made.
    If one places an atom (or a large piece of a matter containing billions and billions of atoms) in a magnetic field, electrons doing their circles inside do not like this very much. They alter their motion in such a way as to oppose this external influence.

    Incidentally, this is the most general principle of Nature: whenever one tries to change something settled and quiet, the reaction is always negative (you can easily check out that this principle also applies to the interaction between you and your parents). So, according to this principle, the disturbed electrons create their own magnetic field and as a result the atoms behave as little magnetic needles pointing in the direction opposite to the applied field*.



    But of course may I infer "floating ships" over mineral deposits that were conducive to transportation in regards to the superconductors, floating frogs and such? An "attenuator of a kind" for the strength's and weaknesses of such composite gatherings?

    But anyway before this "energy is considered in it's matter formed," how did such asymmetrical breaking from the origins not have ocnsidered such constitutions built on the very matters of the moon or such, in it's construction? In the end the gravity field is worth what?

    At SLAC and elsewhere in the 1990s, precision measurements probing quantum effects from physics at higher energy scales were very successful. Precision electroweak measurements accurately predicted the mass of the top quark before it was discovered at the Tevatron at Fermilab, and they were cited in the awarding of the 1999 Nobel Prize to Veltmann and t'Hooft, which recognized their work in developing powerful mathematical tools for calculating quantum corrections and demonstrating that the Standard Model was a renormalizable theory. The discovery and mass measurement of the top quark at Fermilab's Tevatron and the precise Z0 boson mass measurement from CERN experiments added to well established values for other Standard Model parameters, to allow predictions for the only Standard Model parameter not yet measured, the Higgs mass.



    What is a coupling constant? This is some number that tells us how strong an interaction is. Newton's constant GN, which appears in both Newton's law of gravity and the Einstein equation, is the coupling constant for gravitational interactions. For electromagnetism, the coupling constant is related to the electric charge through the fine structure constant a



    While the idea in my mind is "the extension of all elements demonstrated in some way arising from the standard model, what said that "this element or that" could not have been created from a oscillatory expression of the big bang, and the particles that issue forth, are not without some geometrical expression as "inhernet structures" of that table?



    As a "resonantial value" of a point along the length of the string?

    So you see, I had a vision about the future. A time when I will work in space deploying satellites. But what said that future would not ascertain the requirements when our fossil fuels will have to be disregarded? Change the way the planets inhabitants will look forward to the benefits of such conceptual changes?

    So this is a fictional posting then, about that future.
