Dark Energy: Beyond Einstein Missions

Adept

Charles L. Bennett

"ADEPT will measure these supernovae, but its real advance lies in a new, more powerful technique. Patterns in temperature of the very young universe provide a 'standard ruler' that is imprinted on the pattern of galaxies across the sky. ADEPT aims to map these through space and time," according to Bennett

ADEPT promises to provide the galaxy positions needed to follow the historical development of the universe, so that astronomers can determine the role played by the dark energy. Bennett says that the ADEPT mission will help answer many questions about the role played by dark energy in both fundamental physics and cosmology. Jonathan Bagger, chair of the Johns Hopkins physics and astronomy department, agreed. "Twenty-first century physics is at a crossroads," he said. "Our fundamental theories of gravity and quantum mechanics are in conflict. Dark energy might point the way out."

Destiny

Known as Destiny, the Dark Energy Space Telescope, the small spacecraft would detect and observe more than 3,000 supernovae over its two-year primary mission to measure the expansion history of the Universe, followed by a year-long survey of 1,000 square-degrees of the sky at near-infrared wavelengths to measure how the large-scale distribution of matter in the Universe has evolved since the Big Bang. Used together, the data from these two surveys will have 10 times the sensitivity of current ground-based projects to explore the properties of Dark Energy, and will provide data critical to understanding the origin of Dark Energy, which is poorly explained by existing physical theories.

“Destiny’s strength is that it is a simple, low-cost mission designed to attack the puzzling problem of Dark Energy directly with high statistical precision,” said Tod R. Lauer, the Principal Investigator for Destiny and an astronomer at NOAO. “We build upon grism technology used in the Hubble Space Telescope’s Advanced Camera for Surveys to help us provide spectra of the supernovae as well as images. Spectra are critical to diagnosing the properties of the supernova, but are very difficult to obtain with more traditional cameras. Destiny’s grism camera, however, will take simultaneous spectra of all objects in its field. This is a major advantage of our approach, which greatly increases the ability to detect and characterize these distant stellar explosions.”

Snap

NASA will support the SNAP mission concept for probing dark energy by observing distant Type Ia supernova and studying weak gravitational lensing.

SNAP, the SuperNova/Acceleration Probe, is an experiment designed to learn the nature of dark energy by precisely measuring the expansion history of the universe. At present scientists cannot say whether dark energy has a constant value or has changed over time — or even whether dark energy is an illusion, with accelerating expansion being due to a gravitational anomaly instead.

"SNAP will investigate dark energy using two independent and powerful techniques," says Saul Perlmutter of Berkeley Lab's Physics Division, a professor of physics at the University of California at Berkeley who is principal investigator of SNAP and leader of the international Supernova Cosmology Project based at Berkeley Lab. "The best proven and most powerful current technique is to determine changes in the expansion rate by comparing the redshift and distance of Type Ia supernovae, but we are also targeting the most promising complementary technique, called 'weak gravitational lensing.'"

"Lego Block" Galaxies in Early Universe

Witten:

One thing I can tell you, though, is that most string theorist’s suspect that spacetime is a emergent Phenomena in the language of condensed matter physics.

n this image of the Hubble Ultra Deep Field, several objects are identified as the faintest, most compact galaxies ever observed in the distant universe. They are so far away that we see them as they looked less than one billion years after the Big Bang. Blazing with the brilliance of millions of stars, each of the newly discovered galaxies is a hundred to a thousand times smaller than our Milky Way Galaxy.

The bottom row of pictures shows several of these clumps (distance expressed in redshift value). Three of the galaxies appear to be slightly disrupted. Rather than being shaped like rounded blobs, they appear stretched into tadpole-like shapes. This is a sign that they may be interacting and merging with neighboring galaxies to form larger structures.

The detection required joint observations between Hubble and NASA's Spitzer Space Telescope. Blue light seen by Hubble shows the presence of young stars. The absence of infrared light from Spitzer observations conclusively shows that these are truly young galaxies without an earlier generation of stars.

I always like to think that while we refrain from the actual Lego Building block that a child may use, the infancy in our views of the universe, are principles and terms that a condensed matter theorist might use.

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.Robert Laughlin

Dark Matter Issue

We’re faced with the same choices today, with galaxies and clusters playing the role of the Solar System. Except that the question has basically been answered, by observations such as the Bullet Cluster. If you modify gravity, it’s fairly straightforward (although harder than you might guess, if you’re careful about it) to change the strength of gravity as a function of distance. So you can mock up “dark matter” by imagining that gravity at very large distances is just a bit stronger than Newton (or Einstein) would have predicted — as long as the hypothetical dark matter is in the same place as the ordinary matter is.

In Dark Matter Still Existing, Sean Carroll of Cosmic Variance lays the topic out for readers to understand his position on this issue.

An intergalactic collision is providing astronomers with a giant payoff: the first direct evidence of the invisible material that theorists say holds galaxies together and accounts for most of the universe's mass.

CRASH COURSE. This composite image from several observatories and telescopes shows where two clusters of galaxies collided 100 million years ago. The ordinary matter, shown in pink, from the two galaxies collided, whereas the dark matter from each galaxy, shown in purple, passed straight through.

What is Dark Matter? How Can We Make It in the LaboratoryConclusions

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.

Hubble Maps the Cosmic Web of "Clumpy" Dark Matter in 3-D

Three-Dimensional Distribution of Dark Matter in the Universe

This three-dimensional map offers a first look at the web-like large-scale distribution of dark matter, an invisible form of matter that accounts for most of the universe's mass. This milestone takes astronomers from inference to direct observation of dark matter's influence in the universe. Because of the finite speed of light, regions furthest away are also seen as they existed a long time ago. The map stretches halfway back in time to the beginning of the universe.

The map reveals a loose network of dark matter filaments, gradually collapsing under the relentless pull of gravity, and growing clumpier over time. This confirms theories of how structure formed in our evolving universe, which has transitioned from a comparatively smooth distribution of matter at the time of the big bang. The dark matter filaments began to form first and provided an underlying scaffolding for the subsequent construction of stars and galaxies from ordinary matter. Without dark matter, there would have been insufficient mass in the universe for structures to collapse and galaxies to form.

Part of this reporting is the way in which one could look at the Cosmos and see the gravitational relationships, as one might see it in relation to "Lagrangian views" in the Sun Earth Relation.

Make sure you click on the image for further information. Mouseovers as your cursor is placed over images or worded links are equally important. You learn about satellites and the way they travel through these holes.

While one can see "dark matter" in terms of it's constraints, what of "dark energy" as it makes it way through those holes? This reveals the expansionary nature in terms of dark energy being repelled, whether you like to think so or not. This explains the dark energy developing free of the dark matter constraints and explains the state of our universe.

Google Inc. has joined with nineteen other organizations to build the Large Synoptic Survey Telescope, scheduled to see first light atop Cerro Pachón in Chile in 2013.

The Large Synoptic Survey Telescope (LSST) is a proposed ground-based 8.4-meter, 10 square-degree-field telescope that will provide digital imaging of faint astronomical objects across the entire sky, night after night. In a relentless campaign of 15 second exposures, LSST will cover the available sky every three nights, opening a movie-like window on objects that change or move on rapid timescales: exploding supernovae, potentially hazardous near-Earth asteroids, and distant Kuiper Belt Objects. The superb images from the LSST will also be used to trace billions of remote galaxies and measure the distortions in their shapes produced by lumps of Dark Matter, providing multiple tests of the mysterious Dark Energy.

Two simulations of strong lensing by a massive cluster of galaxies. In the upper image, all the dark matter is clumped around individual cluster galaxies (orange), causing a particular distortion of the background galaxies (white and blue). In the lower image, the same amount of mass is more smoothly distributed over the cluster, causing a very different distortion pattern.

Here in this post the example of "how one may see" is further expounded upon to show how dark matter and dark energy are in action as a 90% aspect of the cosmos, while the remaining 10% is a discrete measure of what is cosmologically matter orientated. We don't loose sight of these relationships, but are helped to further develope them in terms of this gravitational relationship.

COSMOS Reveals the Cosmos

Wolf-Rayet star

While I have started off with the definition of the Wolf-Rayet star, the post ends in understanding the aspects of gravity and it's affects, as we look at what has become of these Wolf-Rayet stars in their desimination of it's constituent properties.

Similar, "in my thinking" to the expansion of our universe?


Artist's impression of a Wolf-Rayet star

About 150 Wolf-Rayets are known in our own Milky Way Galaxy, about 100 are known in the Large Magellanic Cloud, while only 12 have been identified in the Small Magellanic Cloud. Wolf-Rayet stars were discovered spectroscopically in 1867 by the French astronomers Charles Wolf and Georges Rayet using visual spectrometery at Paris Observatory.

There are some thoughts manifesting about how one may have see this energy of the Blue giant. It's as if the examples of what began with great force can loose it's momentum and dissipate very quickly(cosmic winds that blow the dust to different places)?


Illustration of Cosmic Forces-Credit: NASA, ESA, and A. Feild (STScI)

Scientists using NASA's Hubble Space Telescope have discovered that dark energy is not a new constituent of space, but rather has been present for most of the universe's history. Dark energy is a mysterious repulsive force that causes the universe to expand at an increasing rate.

What if the Wolf-Rayet star does not produce the jets that are exemplified in the ideas which begin blackhole creation. Is this part of blackhole development somehow in it's demise, that we may see examples of the 150 Wolf-Rayets known in our own Milky Way as example of what they can become as blackholes, or not.

Quark to quark Distance and the Metric

If on such a grand scale how is it thoughts are held in my mind to microscopic proportions may not dominate as well within the periods of time the geometrics develop in the stars now known as Wolf-Rayet. So you use this cosmological model to exemplify micro perspective views in relation to high energy cosmological geometrics.



Plato:

"Lagrangian views" in relation may have been one result that comes quickly to my mind. Taking that chaldni plate and applying it to the universe today.

While I had in the previous post talked about how Lagrangian views could dominate "two aspects of the universe," it is not without linking the idea of what begins as a strong gravitational force to hold the universe together, that over time, as the universe became dominated by the dark energy that the speeding up of inflation could have become pronounced by discovering the holes created in the distances between the planets and their moons. Between galaxies.



I make fun above with the understanding of satellites travelling in our current universe in relation to planets and moons, as well as galaxies. To have taken this view down to WMAP proportions is just part of what I am trying to convey using very simplistic examples of how one may look at the universe, when gravity dominated the universe's expansion versus what has happened to the universe today in terms of speeding up.


LOOP-DE-LOOP. The Genesis spacecraft's superhighway path took it to the Earth-sun gravitational-equilibrium point L1, where it made five "halo" orbits before swinging around L2 and heading home.Ross

If the distances between galaxies have become greater, then what saids that that the ease with which the speeding up occurs is not without understanding that an equilibrium has been attained, from what was once dominate in gravity, to what becomes rapid expansion?

This book describes a revolutionary new approach to determining low energy routes for spacecraft and comets by exploiting regions in space where motion is very sensitive (or chaotic). It also represents an ideal introductory text to celestial mechanics, dynamical systems, and dynamical astronomy. Bringing together wide-ranging research by others with his own original work, much of it new or previously unpublished, Edward Belbruno argues that regions supporting chaotic motions, termed weak stability boundaries, can be estimated. Although controversial until quite recently, this method was in fact first applied in 1991, when Belbruno used a new route developed from this theory to get a stray Japanese satellite back on course to the moon. This application provided a major verification of his theory, representing the first application of chaos to space travel.

Since that time, the theory has been used in other space missions, and NASA is implementing new applications under Belbruno's direction. The use of invariant manifolds to find low energy orbits is another method here addressed. Recent work on estimating weak stability boundaries and related regions has also given mathematical insight into chaotic motion in the three-body problem. Belbruno further considers different capture and escape mechanisms, and resonance transitions.

Providing a rigorous theoretical framework that incorporates both recent developments such as Aubrey-Mather theory and established fundamentals like Kolmogorov-Arnold-Moser theory, this book represents an indispensable resource for graduate students and researchers in the disciplines concerned as well as practitioners in fields such as aerospace engineering.

First Stars Behind the Scene

There are several recognized processes from the early universe that leave relic effects setting the stage for galaxy formation and evolution. We deal here with the first generarion of stars, primordial nucleosynthesis, the epoch of recombination, and the thermal history of various cosmic backgrounds.

Part of understanding the time line is first knowing where the Pregalactic Universe exists in that time line.

Plato:

So given the standard information one would have to postulate something different then what is currently classified?

A new Type III (what ever one shall attribute this to definition), versus Type I, Type IIa?

The idea is to place the distant measure in relation to what is assumed of TYPE I, TypeIIa. It assumes all these things, but has to been defined further, to be a Type III. That's the point of setting the values of where this measure can be taken from.

I wrote someplace else the thought generated above. It is nice that the world of scientists are not so arrogant in some places, while some have been willing to allow the speculation to continue. Even amidst their understanding, that I was less then the scientist that they are, yet recognizing, I am deeply motivated to understanding this strange world of cosmology and it's physics.

When I wrote this title above I was actually thinking of two scenarios that are challenging the way I am seeing it.

WMAP has produced a new, more detailed picture of the infant universe. Colors indicate "warmer" (red) and "cooler" (blue) spots. The white bars show the "polarization" direction of the oldest light. This new information helps to pinpoint when the first stars formed and provides new clues about events that transpired in the first trillionth of a second of the universe.

First of these, was in terms of the time line and what we know of the WMAP demonstration given to us of that early universe. I of course inject some of what I know by past research to help the general public understand what is being demonstrated from another perspective.

This is what happens as you move through different scientists(Wayne Hu) thoughts to see the world in the way they may see it. This concept can be quite revealing sometimes giving a profound effect to moving the mind to consider the universe in new ways.



"Lagrangian views" in relation may have been one result that comes quickly to my mind. Taking that chaldni plate and applying it to the universe today.



Even though in the context of this post, we may see the universe in a "simple experiment" not just demonstrating the "early universe," but the universe in it's "gravitational effect" from that evolution to matter defined now.

The Time Line


Credit: NASA/WMAP Science Team

The expansion of the universe over most of its history has been relatively gradual. The notion that a rapid period "inflation" preceded the Big Bang expansion was first put forth 25 years ago. The new WMAP observations favor specific inflation scenarios over other long held ideas.

Looking to the "far left" of the image we see the place where the cosmic background is being demonstrated, while to the "far right" we see the satellite which has helped measure what we know of the early universe. So this "distant measure" has allowed us to understand what is behind the scene of what we know of cosmology today of events, galaxies and such.

Second, what comes to mind is the Massive Blue Star of 100 Solar masses that would have been further out in terms of the billions of years that we may of sought in terms of our measures. So this would be of value I would assume in relation to model perspective and measures?

So the distance measure has been defined then by understanding the location of the cosmic background and the place where the Blue giants will have unfolded in their demise, to the creation of blackholes.

From the distortion of the images (curved lines) - caused by the gravitation of material between us and the light sources - it is possible to calculate and map the entire foreground mass.Image: Max Planck Institute of Astrophysics

We don't have to wait for the giant telescope to get unparalleled results from this technique, however. One of the most pressing issues in current physics is to gain a better understanding of the mysterious Dark Energy which currently drives the accelerated expansion of the Universe. Metcalf and White show that mass maps of a large fraction of the sky made with an instrument like SKA could measure the properties of Dark Energy more precisely than any previously suggested method, more than 10 times as accurately as mass maps of similar size based on gravitational distortions of the optical images of galaxies.

Hubble Finds Evidence for Dark Energy in the Young Universe

I had to go back to the article for some further reading.


These snapshots, taken by NASA's Hubble Space Telescope, reveal five supernovae, or exploding stars, and their host galaxies.

The arrows in the top row of images point to the supernovae. The bottom row shows the host galaxies before or after the stars exploded. The supernovae exploded between 3.5 and 10 billion years ago.

Astronomers used the supernovae to measure the expansion rate of the universe and determine how the expansion rate is affected by the repulsive push of dark energy, a mysterious energy force that pervades space. Supernovae provide reliable measurements because their intrinsic brightness is well understood. They are therefore reliable distance markers, allowing astronomers to determine how far away they are from Earth.

Pinpointing supernovae in the faraway universe is similar to watching fireflies in your back yard. All fireflies glow with about the same brightness. So, you can judge how the fireflies are distributed in your back yard by noting their comparative faintness or brightness, depending on their distance from you.

Only Hubble can measure these supernovae because they are too distant, and therefore too faint, to be studied by the largest ground-based telescopes.

These Hubble observations show for the first time that dark energy has been a present force for most of the universe's history. A spectral analysis also shows that the supernovae used to measure the universe's expansion rate today look remarkably similar to those that exploded nine billion years ago and are just now seen by Hubble.

These latest results are based on an analysis of the 24 most distant known supernovae, most of them discovered within the last three years by the Higher-z SN Search Team. The images were taken between 2003 and 2005 with Hubble's Advanced Camera for Surveys.

Scientists using NASA's Hubble Space Telescope have discovered that dark energy is not a new constituent of space, but rather has been present for most of the universe's history. Dark energy is a mysterious repulsive force that causes the universe to expand at an increasing rate.

Investigators used Hubble to find that dark energy was already boosting the expansion rate of the universe as long as nine billion years ago. This picture of dark energy is consistent with Albert Einstein's prediction of nearly a century ago that a repulsive form of gravity emanates from empty space.

Data from Hubble provides supporting evidence that help astrophysicists to understand the nature of dark energy. This will allow scientists to begin ruling out some competing explanations that predict that the strength of dark energy changes over time.

Researchers also have found that the class of ancient exploding stars, or supernovae, used to measure the expansion of space today look remarkably similar to those that exploded nine billion years ago and are just now being seen by Hubble. This important finding gives additional credibility to the use of these supernovae for tracking the cosmic expansion over most of the universe's lifetime.

"Although dark energy accounts for more than 70 percent of the energy of the universe, we know very little about it, so each clue is precious," said Adam Riess, of the Space Telescope Science Institute and Johns Hopkins University in Baltimore. Riess led one of the first studies to reveal the presence of dark energy in 1998 and is the leader of the current Hubble study. "Our latest clue is that the stuff we call dark energy was relatively weak, but starting to make its presence felt nine billion years ago."

To study the behavior of dark energy of long ago, Hubble had to peer far across the universe and back into time to detect supernovae. Supernovae can be used to trace the universe's expansion. This is analogous to seeing fireflies on a summer night. Fireflies glow with about the same brightness, so you can judge how they are distributed in the backyard by their comparative faintness or brightness, depending on their distance from you. Only Hubble can measure these ancient supernovae because they are too distant, and therefore too faint, to be studied by the largest ground-based telescopes.

Einstein first conceived of the notion of a repulsive force in space in his attempt to balance the universe against the inward pull of its own gravity, which he thought would ultimately cause the universe to implode.

His "cosmological constant" remained a curious hypothesis until 1998, when Riess and the members of the High-z Supernova Team and the Supernova Cosmology Project used ground-based telescopes and Hubble to detect the acceleration of the expansion of space from observations of distant supernovae. Astrophysicists came to the realization that Einstein may have been right after all: there really was a repulsive form of gravity in space that was soon after dubbed "dark energy."

Over the past eight years astrophysicists have been trying to uncover two of dark energy's most fundamental properties: its strength and its permanence. These new observations reveal that dark energy was present and obstructing the gravitational pull of the matter in the universe even before it began to win this cosmic "tug of war."

Previous Hubble observations of the most distant supernovae known revealed that the early universe was dominated by matter whose gravity was slowing down the universe's expansion rate, like a ball rolling up a slight incline. The observations also confirmed that the expansion rate of the cosmos began speeding up about five to six billion years ago. That is when astronomers believe that dark energy's repulsive force overtook gravity's attractive grip.

The latest results are based on an analysis of the 24 most distant supernovae known, most found within the last two years.

By measuring the universe's relative size over time, astrophysicists have tracked the universe's growth spurts, much as a parent may witness the growth spurts of a child by tracking changes in height on a doorframe. Distant supernovae provide the doorframe markings read by Hubble. "After we subtract the gravity from the known matter in the universe, we can see the dark energy pushing to get out," said Lou Strolger, astronomer and Hubble science team member at Western Kentucky University in Bowling Green, Ky. Further observations are presently underway with Hubble by Riess and his team which should continue to offer new clues to the nature of dark energy.

Cosmic ray spallation

As this NASA chart indicates, 70 percent or more of the universe consists of dark energy, about which we know next to nothing

Other explanations of dark energy, called "quintessence," originate from theoretical high-energy physics. In addition to baryons, photons, neutrinos, and cold dark matter, quintessence posits a fifth kind of matter (hence the name), a sort of universe-filling fluid that acts like it has negative gravitational mass. The new constraints on cosmological parameters imposed by the HST supernova data, however, strongly discourage at least the simplest models of quintessence.

Of course my mind is thinking about the cosmic triangle of an event in the cosmos. So I am wondering what is causing the "negative pressure" as "dark energy," and why this has caused the universe to speed up.


SNAP-Supernova / Acceleration Probe-Studying the Dark Energy of the Universe

The discovery by the Supernova Cosmology Project (SCP) and the High-Z Supernova team that the expansion of the universe is accelerating poses an exciting mystery — for if the universe were governed by gravitational attraction, its rate of expansion would be slowing. Acceleration requires a strange “dark energy’ opposing this gravity. Is this Einstein’s cosmological constant, or more exotic new physics? Whatever the explanation, it will lead to new discoveries in astrophysics, particle physics, and gravitation.

By defining the context of particle collisions it was evident that such a place where such a fluid could have dominated by such energy in stars, are always interesting as to what is ejected from those same stars. What do those stars provide for the expression of this universe while we are cognoscente of the "arrow of time" explanation.


This diagram reveals changes in the rate of expansion since the universe's birth 15 billion years ago. The more shallow the curve, the faster the rate of expansion.

So of course these thoughts are shared by the perspective of educators to help us along. But if one did not understand the nature of the physical attributes of superfluids, how would one know to think of the relativistic conditions that high energy provides for us?


NASA/WMAP Scientific Team: Expanding Universe



So recognizing where these conditions are evident would be one way in which we might think about what is causing a negative pressure in the cosmos.

Given the assumption that the matter in the universe is homogeneous and isotropic (The Cosmological Principle) it can be shown that the corresponding distortion of space-time (due to the gravitational effects of this matter) can only have one of three forms, as shown schematically in the picture at left. It can be "positively" curved like the surface of a ball and finite in extent; it can be "negatively" curved like a saddle and infinite in extent; or it can be "flat" and infinite in extent - our "ordinary" conception of space. A key limitation of the picture shown here is that we can only portray the curvature of a 2-dimensional plane of an actual 3-dimensional space! Note that in a closed universe you could start a journey off in one direction and, if allowed enough time, ultimately return to your starting point; in an infinite universe, you would never return.

Of course it is difficult for me to understand this process, but I am certainly trying. If one had found that in the relativistic conditions of high energy scenarios a "similarity to a flattening out" associated with an accelerating universe what would this say about information travelling from the "origins of our universe" quite freely. How would this effect dark energy?

In physics, a perfect fluid is a fluid that can be completely characterized by its rest frame energy density ρ and isotropic pressure p.

Real fluids are "sticky" and contain (and conduct) heat. Perfect fluids are idealized models in which these possibilities are neglected. Specifically, perfect fluids have no shear stresses, viscosity, or heat conduction.

In tensor notation, the energy-momentum tensor of a perfect fluid can be written in the form

[tex] T^{\mu\nu}=(\rho+p)\, U^\mu U^\nu + P\, \eta^{\mu\nu}\,[/tex]



where U is the velocity vector field of the fluid and where ημν is the metric tensor of Minkowski spacetime.

Perfect fluids admit a Lagrangian formulation, which allows the techniques used in field theory to be applied to fluids. In particular, this enables us to quantize perfect fluid models. This Lagrangian formulation can be generalized, but unfortunately, heat conduction and anisotropic stresses cannot be treated in these generalized formulations.

Perfect fluids are often used in general relativity to model idealized distributions of matter, such as in the interior of a star.

So events in the cosmos ejected the particles, what geometrical natures embued such actions, to have these particle out in space interacting with other forms of matter to create conditions that would seem conducive to me, for that negative pressure?

Cosmic ray spallation is a form of naturally occurring nuclear fission and nucleosynthesis. It refers to the formation of elements from the impact of cosmic rays on an object. Cosmic rays are energetic particles outside of Earth ranging from a stray electron to gamma rays. These cause spallation when a fast moving particle, usually a proton, part of a cosmic ray impacts matter, including other cosmic rays. The result of the collision is the expulsion of large members of nucleons (protons and neutrons) from the object hit. This process goes on not only in deep space, but in our upper atmosphere due to the impact of cosmic rays.

Cosmic ray spallation produces some light elements such as lithium and boron. This process was discovered somewhat by accident during the 1970s. Models of big bang nucleosynthesis suggested that the amount of deuterium was too large to be consistent with the expansion rate of the universe and there was therefore great interest in processes that could generate deuterium after the big bang.

Cosmic ray spallation was investigated as a possible process to generate deuterium. As it turned out, spallation could not generate much deuterium, and the excess deuterium in the universe could be explained by assuming the existence of non-baryonic dark matter. However, studies of spallation showed that it could generate lithium and boron. Isotopes of aluminum, beryllium, carbon(carbon-14), chlorine, iodine and neon, are also formed through cosmic ray spallation.

Talk about getting tongue tied, can you imagine, "these fluctuations can generate their own big bangs in tiny areas of the universe." Read on.

Carroll and Chen’s scenario of infinite entropy is inspired by the finding in 1998 that the universe will expand forever because of a mysterious force called “dark energy.” Under these conditions, the natural configuration of the universe is one that is almost empty. “In our current universe, the entropy is growing and the universe is expanding and becoming emptier,” Carroll said.

But even empty space has faint traces of energy that fluctuate on the subatomic scale. As suggested previously by Jaume Garriga of Universitat Autonoma de Barcelona and Alexander Vilenkin of Tufts University, these fluctuations can generate their own big bangs in tiny areas of the universe, widely separated in time and space. Carroll and Chen extend this idea in dramatic fashion, suggesting that inflation could start “in reverse” in the distant past of our universe, so that time could appear to run backwards (from our perspective) to observers far in our past.

Tunnelling in Faster then Light

Underneath this speculation of mine is the geometrical inclination of the universe in expression. If it's "dynamical nature is revealed" what allows us to think of why this universe at this time and junction, should be flat(?) according to the time of this universe in expression?

Omega=the actual density to the critical density

If we triangulate Omega, the universe in which we are in, Omegam(mass)+ Omega(a vacuum), what position geometrically, would our universe hold from the coordinates given?

Positive energy density gives spacetime of the universe a positive curvature. A sphere? Negative curvature a region of spacetime that is negative and curved like a saddle? For time travel, and travel into the past, you need a universe that has a negative energy density.

Thus the initial idea here to follow is that the process had to have a physics relation. This is based on the understanding of anti-particle/particle, and what becomes evident in the cosmos as a closed loop process. Any variation within this context, is the idea of "blackhole anti-particle expression" based on what can be seen at the horizon?



A anti-particle can be considered as a particle moving back in time? Only massless particle can travel faster then light. Only faster then light massless particles can travel back in time? So of course, I am again thinking of the elephant process of Susskind and the closed loop process of the virtual particle/anti-particle. What comes out of it?

That's not all. The fact that space-time itself is accelerating - that is, the expansion of the universe is speeding up - also creates a horizon. Just as we could learn that an elephant lurked inside a black hole by decoding the Hawking radiation, perhaps we might learn what's beyond our cosmic horizon by decoding its emissions. How? According to Susskind, the cosmic microwave background that surrounds us might be even more important than we think. Cosmologists study this radiation because its variations tell us about the infant moments of time, but Susskind speculates that it could be a kind of Hawking radiation coming from our universe's edge. If that's the case, it might tell us something about the elephants on the other side of the universe.

So the anti-particle falls into the blackhole? How is it that I resolve this?? You can consider the anti-particle as traveling back in time. The micro perspective of the blackhole allows time travel backwards.

Although a 1916 paper by Ludwig Flamm from the University of Vienna [4] is sometimes cited as giving the first hint of a wormhole, "you definitely need hindsight to detect it," says Matt Visser of Victoria University in Wellington, New Zealand. Einstein and Rosen were the first to take the idea seriously and to try to accomplish some physics with it, he adds. The original goal may have faded, but the Einstein-Rosen bridge still pops up occasionally as a handy solution to the pesky problem of intergalactic travel.

There are two cases in which the thoughts about faster then light particles are created and this is the part where one tries to get it right so as not to confuse themselves and others.

Wormholes?

Plato:

So "open doorways" and ideas of "tunneling" are always interesting in terms of how we might look at an area like GR in cosmology? Look for way in which such instances make them self known.

Are they applicable to the very nature of quantum perceptions that such probabilities could have emerged through them? Held to "time travel scenarios" and grabbed the history of what had already preceded us in past tense, could have been brought again forward for inspection?

Sure I am quoting myself here, just to show one of the options I am showing by example. The second of course is where I was leading too in previous posts.

So I was thinking here in context of one example in terms of the containment of the "graviton in a can" is really letting loose of the information in the collision process, as much as we like this "boundary condition" it really is not so.

Another deep quantum mystery for which physicists have no answer has to do with "tunneling" -- the bizarre ability of particles to sometimes penetrate impenetrable barriers. This effect is not only well demonstrated; it is the basis of tunnel diodes and similar devices vital to modern electronic systems.

Tunneling is based on the fact that quantum theory is statistical in nature and deals with probabilities rather than specific predictions; there is no way to know in advance when a single radioactive atom will decay, for example.

The probabilistic nature of quantum events means that if a stream of particles encounters an obstacle, most of the particles will be stopped in their tracks but a few, conveyed by probability alone, will magically appear on the other side of the barrier. The process is called "tunneling," although the word in itself explains nothing.

Chiao's group at Berkeley, Dr. Aephraim M. Steinberg at the University of Toronto and others are investigating the strange properties of tunneling, which was one of the subjects explored last month by scientists attending the Nobel Symposium on quantum physics in Sweden.

"We find," Chiao said, "that a barrier placed in the path of a tunneling particle does not slow it down. In fact, we detect particles on the other side of the barrier that have made the trip in less time than it would take the particle to traverse an equal distance without a barrier -- in other words, the tunneling speed apparently greatly exceeds the speed of light. Moreover, if you increase the thickness of the barrier the tunneling speed increases, as high as you please.

"This is another great mystery of quantum mechanics."

Of course I am looking for processes in physics that would actually demonstrate this principal of energy calculated at the very beginning of the collision process, now explained in the detector, minus the extra energy that had gone where?



This is the basis for the "Graviton in a can" example of what happens in the one scenario.

Plato:

A Bose-Einstein condensate (such as superfluid liquid helium) forms for reasons that only can be explained by quantum mechanics. Bose condensates form at low temperature

Plasmas and Bose condensates

So in essence the physics process that I am identifying is shown by understanding that the "graviton production" allows that energy to be transmitted outside the process of the LHC?

This is the energy that can be calculated and left over from all the energy assumed in the very beginning of this collision process. Secondly, all energy used in this process would be in association with bulk perspective.

This now takes me to the second process of "time travel" in the LHC process. The more I tried to figure this out the basis of thought here is that Cerenkov radiation in a vacuum still is slower then speed of light, yet within the medium of ice, this is a different story. So yes there are many corrections and insight here to consider again.

The muon will travel faster than light in the ice (but of course still slower than the speed of light in vacuum), thereby producing a shock wave of light, called Cerenkov radiation. This light is detected by the photomultipliers, and the trace of the neutrinos can be reconstructed with an accuracy of a couple of degrees. Thus the direction of the incoming neutrino and hence the location of the neutrino source can be pinpointed. A simulation of a muon travelling through AMANDA is shown here (1.5 MB).

So while sleeping last night the question arose in my mind as to the location of where the "higgs field" will be produced in the LHC experiment? Here also the the thoughts about the "cross over point" that would speak to the idea here of what reveals faster then light capabilities arising from the collision process?

What are the main goals of the LHC?-

The LHC will also help us to solve the mystery of antimatter. Matter and antimatter must have been produced in the same amounts at the time of the Big Bang. From what we have observed so far, our Universe is made of only matter. Why? The LHC could provide an answer.

It was once thought that antimatter was a perfect 'reflection' of matter - that if you replaced matter with antimatter and looked at the result in a mirror, you would not be able to tell the difference. We now know that the reflection is imperfect, and this could have led to the matter-antimatter imbalance in our Universe.

The strongest limits on the amount of antimatter in our Universe come from the analysis of the diffuse cosmic gamma-rays arriving on Earth and the density fluctuations of the cosmic background radiation. If one asumes that after the Big Bang, the Universe separated somehow into different domains where either matter or antimatter was dominant, then at the boundaries there should be annihilations, producing cosmic gamma rays. In both cases the limit proposed by current theories is practically equivalent to saying that there is no antimatter in our Universe.

So we get the idea here in the collision process and from it the crossover point leaves a energy dissertation on what transpired from this condition and left the idea in my mind about the circumstances of what may have changed the the speed of the cosmos at varying times in the expansion process within our universe. So, this is where I was headed as I laid out the statement below.

Of course this information is based on 2003 data but the jest of the idea here is that in order to go to a "fast forward" the conditions had to exist previously that did not included "sterile neutrinos" and were a result of this "cross over."

So what is the jest of my thought here that I would go to great lengths here to speak about the ideas of what happens within the cosmos to change those varying times of expansion? It has to do with the Suns and the process within those suns that give the dark energy some value, in it's anti- gravity nature to align our selves and our thinking to the cosmological constant of Einstein. If we juggle the three ring circus we find that the curvature parameters can and do hold thoughts govern by the cosmological constant?

It is thus equally important to identify this "physics process" that would allow such changes in the cosmos. So that we can understand the dynamical nature that the cosmos reveals to us can and does allow aspect of its galaxies within context of the universe to increase this expansive process while we question what drives such conditions.

Result of Effective Changes in the Cosmos

"There comes a time when the mind takes a higher plane of knowledge but can never prove how it got there. All great discoveries have involved such a leap. The important thing is not to stop questioning." Albert Einstein (1879- 1955)

But the presence of an event horizon implies a finite Hawking temperature and the conditions for defining the S Matrix cannot be fulfilled. This lack of an S Matrix is a formal mathematical problem not only in string theory but also in particle theories.

One recent attempt to address this problem invokes quantum geometry and a varying speed of light. This remains, as they say, an active area of research. But most experts doubt that anything so radical is required.

What processes would allow you to see "faster then light entities" being shown as examples of that "cross over point?" That's part of the fun isn't it when you realize what some experiments are actually checking for? :)



So yes of course, you might think about "Cerenkov radiation" and from this, what is happening in today's world, that allows us lay people, never having seen or understood, but may now do so?

SNO

The Sudbury Neutrino Observatory is a collaborative effort among physicists from Canada, the U.K., and the U.S. Using 1,000 tons of so-called heavy water and almost 10,000 photon detectors, they measure the flux, energy, and direction of solar neutrinos, which originate in the sun. SNO, located 6,800 feet underground in an active Ontario nickel mine, can also detect the other two types of neutrinos, muon neutrinos and tau neutrinos. In 2001, just two years after the observatory opened, physicists at SNO solved the 30-year-old mystery of the "missing solar neutrinos." They found that the answer lies not with the sun—where many physicists had suspected that solar neutrinos undergo changes—but with the journey they take from the core of the sun to the Earth.

In the previous article I mention the "cross over point in LHC" and from this, the idea was born in mind, how the universe and the effectives rates of expansion could take place?



While it is a long shot, I thought since of layman status, what could it hurt but to speculate and see what thoughts further arise from this. Like any model perspective adopted, allows new thinking to emerge, where previously, none existed for me. So one tends to try and go with the flow and see where it ends up. At least that's what I do and now, others do too?


Blackhole Production in the Cosmos

Increase, in high energy collisions taking place, allows speed up of inflation?



So here is the jest of what allowed me to say that the effective rates of exchange in the cosmos had to have the physics related to show the reasons why the effective speed up of inflation has been detected.

Some theorists envision the universe as multidimensional space-time embedding a membranous entity, called a brane, also of multiple dimensions. Diagram depicts familiar 3-dimensional space (time not shown) as a vertical line. At every point along line, one extra dimension curls around with a radius (r) of no more that about 10–19 meter. Perpendicular to every point of the brane extends the bulk, another extra dimension.

Also I will give the idea of "photo/graviton association" and how "graviton in a can" allows perspective about the "effective field variations" that "may be" predicted in the vacuum as it produces new physics to emerge on the other side? Quite a mouthful I know.


The graviton is the quantum force carrier of gravity. In conventional quantum field theory, graviton processes with loops do not make sense because of incurable divergencies.

The idea then here is to understand the graviton production in particle collisions here produce some interesting "phenomena" as we see faster then light entities move beyond the confines of that "graviton in a can." So you get the jest then, that even if the boundary conditions are experimentally being tested here, the production of gravitons is very high.

So what allows faster then light entities to move beyond these confines if you did not understand the connection to the "perfect fluid" and the anomalistic nature this perfect fluid has for allowing such traversing beyond the standard model?

That's not all. The fact that space-time itself is accelerating - that is, the expansion of the universe is speeding up - also creates a horizon. Just as we could learn that an elephant lurked inside a black hole by decoding the Hawking radiation, perhaps we might learn what's beyond our cosmic horizon by decoding its emissions. How? According to Susskind, the cosmic microwave background that surrounds us might be even more important than we think. Cosmologists study this radiation because its variations tell us about the infant moments of time, but Susskind speculates that it could be a kind of Hawking radiation coming from our universe's edge. If that's the case, it might tell us something about the elephants on the other side of the universe.

Three Ring Circus: Dark Energy

"Observations always involve theory."Edwin Hubble

Hopefully some day, I will be accepted as a student of this universe, and it's intrigue?



Sometimes it is necessary to understand that having come to different consclusion about the geometry of this universe that underneath the complexity of these equations a schematic drawing of reality is unfolding? I think this is where Einstein's success came from? So assume from this point a supersymmetrical view of the universe?

You can check out Wayne Hu's site for further info on computer simulation below

As the Universe expands, galaxies become more and more distant from each other. For an observer, such as ourselves, it appears that all other galaxies fly away from us. The further the galaxy, the faster it appears to recede. This recession affects the light emitted by the distant galaxies, stretching the wavelengths of emitted photons due to the Doppler redshift effect. The distance between galaxies is proportionalto the measure of this effect 1+z, where z is what astronomers call redshift. The redshift can be measured for each object if its spectrum is measured.

All three geometrical positions demonstrated below each held the cosmologists to views of our universe. But we now know that Einstein may have been right. What allows us to think this way?

Sorry about the quality of artistic rendition. But you get the jest right?

Why is the universe speeding up, and what does this mean geometrically? There has to be some physics going on that would explain this? What may this be?

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.

Of course this information is based on 2003 data but the jest of the idea here is that in order to go to a "fast forward" the conditions had to exist previously that did not included "sterile neutrinos" and were a result of this "cross over."

If we look back to the measures of supernova Ia measure and find that in that time measure there were differences in the inflationary aspect of that universe, then, the universe today would have allowed us to consider the universe quite capable of changing it's speed of inflation.

While indeed we had held to inverse square law in our assumptions, what shall we do now? As you know, spending a couple of years on my own, I am learning, and yes, it shows sometimes. The "idea back then" presented by Savas Dimopoulos of Stanford University. "This gives us a totally new perspective for addressing theoretical and experimental problems," is what was understood in any theoretical development by scientists then and today?

Inverse Fourth Power Law


Savas Dimopoulos of Stanford University

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

Also, I wouldn't one to think that the experimental process had been defunct what we are doing with Cosmic ray collision processes, to not include it with what the LHC is doing as well. Not only have we created the conditions for it in LHC we recognize as a natural process.

While we know of the components of our universe distributed we understand that their is a part of this whole thing that is casing some questions about what we had thought held to the big bomb's inverse square law rules.

What is causing the Speed increase?

While indeed the layman here speculates, it made more sense if we can now explain what is going on. It has been a long journey in terms of comprehension development but I must say it has been rewarding.



So while indeed I show cosmos particle showers here, it is to point out something that helps to fuel the idea behind the speeding up and slowing down of the universe? Cross over production demonstrate in LHC serves also to speak to the fluctuations in "differing speeds of inflation" in our cosmos?

The "crossover" is a point in the collision process of LHC. So by creating these conditions in the LHC, we have effectively recognized where the "new physics" will emerged from. Also, it presents the opportunity for the "first time here" to address what the effects of the LHC will do for us in terms of what has been presented in terms of the dark energy announced below.



So as close as we came to discerning the mass of the neutrino, what have we now come to know? That their could be "a form" of dark matter? The "point here" was to look for the crossover that was taking place and presenting the opportunities for "new physics" to emerge.

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.

I have some "thought bubbles" percolating to the surface awareness of my mind(a philosopher?), so we will have to see what strange brew materializes. This is a post in developmental mode.

Scientists using NASA's Hubble Space Telescope have discovered that dark energy is not a new constituent of space, but rather has been present for most of the universe's history. Dark energy is a mysterious repulsive force that causes the universe to expand at an increasing rate. Investigators used Hubble to find that dark energy was already boosting the expansion rate of the universe as long as nine billion years ago. This picture of dark energy is consistent with Albert Einstein's prediction of nearly a century ago that a repulsive form of gravity emanates from empty space. Data from Hubble provides supporting evidence to help astrophysicists to understand the nature of dark energy. This will allow them to begin ruling out some competing explanations that predict that the strength of dark energy changes over time.

The title itself of this blog post is not to make fun of what is happening in cosmology right now with the new announcement today. It is about "forcing the mind" to look at "Friedman's equation" in each of the rings. Now the thought is the "whole show" is the Einstein cosmsological constant circus and entertainment, that is happening simultaneously.

Yet it is the idea of the "oscillating nature" behind the geometrical principals that is what I am speculating about.

But thanks to good professor below there is an more in depth explanation shared.



Maybe with the development of the vision, "beyond the spacetime" we had come to know and love, we have now come to a unique point in time? That we understand the greater "depth of the universe" is now open for questions about it's inherent nature?
