The Least Resistance as Possible?



It is always of interest that communications over longer distances is made most capable and following an ole effect we see that where such tunneling allows such a process?

 Kapusta points out that the condensation temperature would be well below the cosmic background temperature, so it would be quite a feat to make this superfluid. However, Kapusta also notes that a sufficiently advanced civilization might use pulses of neutrino superfluid for long-distance communications.

On an abstract level how is one able to envision such a process unless such a hole provides for information to move through a center,  and information to move very fast.
Magnetism is a fundamental interaction shaping our physical world, at the basis of technologies such as magnetic recording or energy generation. Unlike electromagnetic waves, which can be routed and transmitted with waveguides to long distances, magnetic fields rapidly decay with distance. Here we present the concept, design, and properties of a magnetic hose which enables to transfer the static magnetic field generated by a source to an arbitrary distance, and along any given trajectory. We experimentally demonstrate the field transmission through the simplest hose realization using a superconducting shell with a magnetic core. We discuss possible application of magnetic hoses to harness quantum systems by addressable magnetic fields, in the context of quantum information processing.Magnetic hose: Routing and Long-distance Transportation of Magnetic Fields

Music of the Quantum



The weird quantum nature of the atomic world challenges us to revise the way we view the world around us. We learn that our everyday world - built out of the myriad superposition of matter waves, has an unexpected capacity for new kinds of behavior and "self organization" that we are only just beginning to fathom.

Cassiopeia A

In conclusion, we have a rich panorama of experiments that all make use of neutrinos as probes of exotic phenomena as well as processes which we have to measure better to gain understanding of fundamental physics as well as gather information about the universe. See:Vernon Barger: perspectives on neutrino physics May 22, 2008


This image presents a beautiful composite of X-rays from Chandra (red, green, and blue) and optical data from Hubble (gold) of Cassiopeia A, the remains of a massive star that exploded in a supernova. Evidence for a bizarre state of matter has been found in the dense core of the star left behind, a so-called neutron star, based on cooling observed over a decade of Chandra observations. The artist's illustration in the inset shows a cut-out of the interior of the neutron star where densities increase from the crust (orange) to the core (red) and finally to the region where the "superfluid" exists (inner red ball).

This is an artist's impression of the neutron star at the center of the Cassiopeia A supernova remnant. The different colored layers in the cutout region show the crust (orange), the higher density core (red) and the part of the core where the neutrons are thought to be in a superfluid state (inner red ball). The blue rays emanating from the center of the star represent the copious numbers of neutrinos that are created as the core temperature falls below a critical level and a superfluid is formed.

X-ray and Optical Images of Cassiopeia A
Two independent research teams studied the supernova remnant Cassiopeia A, the remains of a massive star, 11,000 light years away that would have appeared to explode about 330 years as observed from Earth. Chandra data are shown in red, green and blue along with optical data from Hubble in gold. The Chandra data revealed a rapid decline in the temperature of the ultra-dense neutron star that remained after the supernova. The data showed that it had cooled by about 4% over a ten-year period, indicating that a superfluid is forming in its core.

Physicists Discover How to Entangle at High Temperatures

While I do not just like to echo in the world of information it is important to me to see how we can use entanglement to give us information about quantum gravity. Is it possible?


Entanglement is the weird quantum process in which two objects share the same existence. So a measurement on one object immediately influences the other, not matter how far apart they may be.
Entanglement is a strange and fragile thing. Sneeze and it vanishes. The problem is that entanglement is destroyed by any interaction with the environment and these interactions are hard to prevent. So physicists have only ever been able to study and exploit entanglement in systems that do not interact easily with the environment, such as photons, or at temperatures close to absolute zero where the environment becomes more benign.

In fact, physicists believe that there is a fundamental limit to the thermal energies at which entanglement can be usefully exploited. And this limit is tiny, comparable to very lowest temperatures.
Today, Fernando Galve at the University of the Balearic Islands in Spain and a few buddies, show how this limit can be dramatically increased. The key behind their idea is the notion of a squeezed state.
In quantum mechanics, Heisenberg's uncertainty principle places important limits on how well certain pairs of complementary properties can be observed. For example, the more accurately you measure position, the less well you can determine momentum. The same is true of energy and time and also of the phase and amplitude of a quantum state.

Physicists have learnt how to play around with these complementary observables to optimise the way they make measurements. They've discovered that they can trade their knowledge of one complementary observable for an improvement in the other. See more here:Physicists Discover How to Entangle at High Temperatures

Macroscopic Similarities in a Microscopic World

Berkeley Lab Technology Dramatically Speeds Up Searches of Large DatabasesJon Bashor


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

It's not just about "mathematical abstraction" but of seeing what good it can be used for. One can be in denial about the prospects but while it gives perspective to current situations, in that it helps to direct thinking forward instead feeling as if "you are just floating in space without being able to move."

Helpless are we? Not considering flapping one's wings?

Imagine indeed then,  trying to orientate direction toward the spacecraft when "floating in space" seems like having to attempt to ride a bicycle for the first time, so one should  know we must balance ourselves while doing the appropriate movements directed to where we want to go. It's something that has to be learn in theoretical enterprise while still held to earth's environ?

There might be a middle way. String theory's mathematical tools were designed to unlock the most profound secrets of the cosmos, but they could have a far less esoteric purpose: to tease out the properties of some of the most complex yet useful types of material here on Earth.

Both string theorists and condensed matter physicists - those studying the properties of complex matter phases such as solids and liquids - are enthused by the development. "I am flabbergasted," says Jan Zaanen, a condensed matter theorist from the University of Leiden in the Netherlands. "The theory is calculating precisely what we are seeing in experiments."
See:What string theory is really good for

So how has this helped the idea of "minimum length?"

Using the anti–de Sitter/conformal field theory correspondence to relate fermionic quantum critical fields to a gravitational problem, we computed the spectral functions of fermions in the field theory. By increasing the fermion density away from the relativistic quantum critical point, a state emerges with all the features of the Fermi liquid. See:String Theory, Quantum Phase Transitions, and the Emergent Fermi Liquid
So we have a beginning here for consideration within the frame work of Condense matter theorist state of existence? String theory is working along side of to direct the idea of matter formation?

Our work is about comparing the data we collect in the STAR detector with modern calculations, so that we can write down equations on paper that exactly describe how the quark-gluon plasma behaves," says Jerome Lauret from Brookhaven National Laboratory. "One of the most important assumptions we've made is that, for very intense collisions, the quark-gluon plasma behaves according to hydrodynamic calculations in which the matter is like a liquid that flows with no viscosity whatsoever."

Proving that under certain conditions the quark-gluon plasma behaves according to such calculations is an exciting discovery for physicists, as it brings them a little closer to understanding how matter behaves at very small scales. But the challenge remains to determine the properties of the plasma under other conditions.

"We want to measure when the quark-gluon plasma behaves like a perfect fluid with zero viscosity, and when it doesn't," says Lauret. "When it doesn't match our calculations, what parameters do we have to change? If we can put everything together, we might have a model that reproduces everything we see in our detector."

Looking back in time toward the beginning of our universe has been one of the things that have been occupying my time as I look through experimental procedures that have been developed. While LHC  provides a template of all the historical drama of science put forward,  it is also a platform in my mind for pushing forward perspective from "a beginning of time scenario" that helps us identify what happens in that formation. Helps us to orientate space and what happens to it.

It provides for me a place where we can talk about a large scale situation in terms of the universe as to what it contains to help motivate this universe to become what it is.

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

In one form or another, the issue of the ultimate beginning has engaged philosophers and theologians in nearly every culture. It is entwined with a grand set of concerns, one famously encapsulated in an 1897 painting by Paul Gauguin: D'ou venons-nous? Que sommes-nous? Ou allons-nous? "Where do we come from? What are we? Where are we going?"
See here for more information.

So how did this process help orientate the things that were brought forward under the idea that the universe is a "cosmological box" that people want to talk about, while in my mind ,it became much more flexible topic when Venezianno began to talk about what came before. What existed outside that box. Abstractly, the box had six faces, to which direction of possibilities became part of the depth of this situation. It was a matter indeed of thinking outside the box.

I know that for some,  why waste one's time, but for me it is the motivator( not God as a creator, but of what actually propels this universe) and to what can exist now that draws my attention. It has been ever so slightly pushed "back in time" to see that the universe began with "microscopic processes that defines the state of the state of the universe in the way it is now." The LHC should be able to answer this although it is still restricted by the energy valuation given to this process.

Physical Reality Of String Theory Shown In Quantum-critical State Of Electrons

Quantum soup

But now, Zaanen, together with his colleagues Cubrovic and Schalm, are trying to change this situation, by applying string theory to a phenomenon that physicists, including Zaanen, have for the past fifteen years been unable to explain: the quantum-critical state of electrons. This special state occurs in a material just before it becomes superconductive at high temperature. Zaanen describes the quantum-critical state as a 'quantum soup', whereby the electrons form a collective independent of distances, where the electrons exhibit the same behaviour at small quantum mechanical scale or at macroscopic human scale.

Fermions and the AdS/CFT correspondence: quantum phase transitions and the emergent Fermi-liquid

A central mystery in quantum condensed matter physics is the zero temperature quantum phase transition between strongly renormalized Fermi-liquids as found in heavy fermion intermetallics and possibly high Tc superconductors. Field theoretical statistical techniques are useless because of the fermion sign problem, but we will present here results showing that the mathematics of string theory is capable of describing fermionic quantum critical states. Using the Anti-de-Sitter/Conformal Field Theory (AdS/CFT) correspondence to relate fermionic quantum critical fields to a gravitational problem, we compute the spectral functions of fermions in the field theory. Deforming away from the relativistic quantum critical point by increasing the fermion density we show that a state emerges with all the features of the Fermi-liquid. Tuning the scaling dimensions of the critical fermion fields we find that the quasiparticle disappears at a quantum phase transition of a purely statistical nature, not involving any symmetry change. These results are obtained by computing the solutions of a classical Dirac equation in an AdS space time containing a Reissner-Nordstrom black hole, where the information regarding Fermi-Dirac statistics in the field theory is processed by quasi-normal Dirac modes at the outer horizon.

Pushing Back Time

Credit: X-ray: NASA/CXC/PSU/S.Park & D.Burrows.; Optical: NASA/STScI/CfA/P.Challis

February 24, 2007 marks the 20th anniversary of one of the most spectacular events observed by astronomers in modern times, Supernova 1987A. The destruction of a massive star in the Large Magellanic Cloud, a nearby galaxy, spawned detailed observations by many different telescopes, including NASA's Chandra X-ray Observatory and Hubble Space Telescope. The outburst was visible to the naked eye, and is the brightest known supernova in almost 400 years.

This composite image shows the effects of a powerful shock wave moving away from the explosion. Bright spots of X-ray and optical emission arise where the shock collides with structures in the surrounding gas. These structures were carved out by the wind from the destroyed star. Hot-spots in the Hubble image (pink-white) now encircle Supernova 1987A like a necklace of incandescent diamonds. The Chandra data (blue-purple) reveals multimillion-degree gas at the location of the optical hot-spots. These data give valuable insight into the behavior of the doomed star in the years before it exploded.

Twenty Years Since a Spectacular Explosion
(Bold added by me for emphasis)


Supernova Starting Gun: Neutrinos

.....
Next they independently estimated how the hypothetical neutrinos would be picked up in a detector as massive as Super-Kamiokande in Japan, which contains 50,000 tons of water. The detector would only see a small fraction of the neutrinos. So the team outlined a method for matching the observed neutrinos to the supernova's expected luminosity curve to figure out the moment in time--to within about 10 milliseconds--when the sputtering star would have begun emitting neutrinos. In their supernova model, the bounce, the time of the first gravitational waves, occurs about 5 milliseconds before neutrino emission. So looking back at their data, gravitational wave hunters should focus on that point in time.

SuperCritical Fluid

What choice do I have but to quote myself.:)

At 11:47 AM, January 09, 2009, Blogger Plato said...
Superfluous is a mathematical construct for sure. Continuity, asked not from the condense matter theorist point of view as Jacque's remind, or, as Susskind speaks of Laughlin( was Susskind ever aware of Witten's statements?)


Edward WittenEdward Witten's Homepage

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.

Now I write this link and quote above because it set my own mind in motion, from that point. I began looking at the experiments and trying to derive something that was consistent in that process that would lead into that same logical conclusion that we are "seeing" and "not seeing" what happens.

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


You must know there is a reason that I am showing these articles just to provide consideration and will put up some information here soon that deals with this point.

I would say I do and am always impressed by Lubo's candidness, so I do not derive any solution to this process and it remains a troubling aspect of my research. The counter argument I produce I had discovering along the way to provide an example in a comment section that deals with what I am saying to Zephir here in this blog entry, under the idea of the landscape. I would ask that Lubos look a little closer and speak to the idea of the Landscape even though under the tutelage of Tom Banks, he specifics his reluctance.

You must also know that I do not align myself with any current research model( disaster scenarios specific LHC.Org) other then to say I recognize facets "of this thinking from my own research" and that this presentation speaks to that. If there is no math involved then how can it represent the landscape in thinking? Logical conclusions, follow logical math processes in String theory?

Letting our minds be consoled with the understanding that cosmic particle collisions take place on earth is the point I am making about seeing "the sun in gamma" and understanding that such measures allow us to see this way. It also helps us to understand that such a location(microscopic blackholes) allows information to travel faster then light in the medium of earth, so that we understand that things can travel "through and tunnel." Information is conserved.

A supercritical fluid is any substance at a temperature and pressure above its thermodynamic critical point. It can diffuse through solids like a gas, and dissolve materials like a liquid. Additionally, close to the critical point, small changes in pressure or temperature result in large changes in density, allowing many properties to be "tuned". Supercritical fluids are suitable as a substitute for organic solvents in a range of industrial and laboratory processes. Carbon dioxide and water are the most commonly used supercritical fluids, being used for decaffeination and power generation respectively.

    For explanation of these animations see: The behaviour of dense particle systems.

    From certain perspective, the AWT is extrapolation of free fermion models of string field theory to zero dimension. These models are nothing very new in physics, as some physicists have assumed, the strings are composed from more fundamental particles (so called preons) already. The one-dimensional strings are just the lowest number of dimensions, which the formal math can handle without problem, while avoiding the singularities. The concept of environment composed from zero dimensional particles is naturally singular from formal math perspective, so it cannot use it. It can be replaced by one-dimensional strings partially, but here's a technical problem: such approximation leads to
    landscape of 10E+500 possible solutions
    , so it's unusable from practical reasons. While from particle model of Aether is evident, such system enables the only way of it's compactification, leading to dynamic mesh of one-dimensional density fluctuations (i.e. "strings") naturally - so no assumption of strings, no assumption of relativity and quantum mechanics postulates is required here at all. By such way, the zero-dimensional approach follows the Occam razor criterion, which
    minimizes the number of postulates
    in theories.

    Is the LHC Leaking Energy?

    This is not to bring "the doom and gloom of micro blackhole creation" into the picture although I do see that the QGP arrived at can bring other perspectives forward, that would relegate questions to my mind.

    For instance.

    So to be clear then, the QGP is relativistic. This I understood already.

    This to me was an indication of string theories work to bring a GUT to the process. Of course I speculate. I am also speculating on the "loss of energy" in the collider process.

    MIT physicists create new form of matter by Lori Valigra, Special to MIT News Office June 22, 2005

    "In superfluids, as well as in superconductors, particles move in lockstep. They form one big quantum-mechanical wave," explained Ketterle. Such a movement allows superconductors to carry electrical currents without resistance.

    To cool it, brings the "same process," as to the condition extended to the QGP? This is the point I am trying to make. If they are aligned?


    Now the quote above was addressed for clarification, and was caught by a spam filter. So the answer may or may not be forth coming.

    As a common folk, I am asking the question from one of ignorance, and would of course like an answer . It is not my wish to "propagate the untruthfulness" that any good scientist would wish to find deteriorates the quality of our current scientific endeavours as a society.

    The Extra Dimensions in the LHC

    String Theorists, for a million bucks, do you think you can answer "the question" and it's applicability?

    Now it should be clear here that while I speak of extra dimensions I am referring to that energy that is not accountable, "after the collision process and particle identifications have been calculated."

    For the first time the LHC reaches temperatures colder than outer space

    Geneva, 10 April 2007. The first sector of CERN1's Large Hadron Collider (LHC) to be cooled down has reached a temperature of 1.9 K (–271°C), colder than deep outer space! Although just one-eighth of the LHC ring, this sector is the world’s largest superconducting installation. The entire 27–kilometre LHC ring needs to be cooled down to this temperature in order for the superconducting magnets that guide and focus the proton beams to remain in a superconductive state. Such a state allows the current to flow without resistance, creating a dense, powerful magnetic field in relatively small magnets. Guiding the two proton beams as they travel nearly the speed of light, curving around the accelerator ring and focusing them at the collision points is no easy task. A total of 1650 main magnets need to be operated in a superconductive state, which presents a huge technical challenge. "This is the first major step in the technical validation of a full-scale portion of the LHC," explained LHC project leader Lyndon Evans.

    There are three parts to the cool down process, with many tests and intense checking in between. During the first phase, the sector is cooled down to 80 K, slightly above the temperature of liquid nitrogen. At this temperature the material will have seen 90% of the final thermal contraction, a 3 millimetre per metre shrinkage of steel structures. Each of the eight sectors is about 3.3 kilometres long, which means shrinkage of 9.9 metres! To deal with this amount of shrinkage, specific places have been designed to compensate for it, including expansion bellows for piping elements and cabling with some slack. Tests are done to make sure no hardware breaks as the machinery is cooled.

    The second phase brings the sector to 4.5 K using enormous refrigerators. Each sector has its own refrigerator and each of the main magnets is filled with liquid helium, the coolant of choice for the LHC because it is the only element to be in a liquid state at such a low temperature.

    The final phase requires a sophisticated pumping system to help bring the pressure down on the boiling Helium and cool the magnets to 1.9 K. To achieve a pressure of 15 millibars, the system uses both hydrodynamic centrifugal compressors operating at low temperature and positive-displacement compressors operating at room temperature. Cooling down to 1.9 K provides greater efficiency for the superconducting material and helium's cooling capacity. At this low temperature helium becomes superfluid, flowing with virtually no viscosity and allowing greater heat transfer capacity.

    “It's exciting because for more than ten years people have been designing, building and testing separately each part of this sector and now we have a chance to test it all together for the first time,” said Serge Claudet, head of the Cryogenic Operation Team. For more information and to see regular updates, see http://lhc.web.cern.ch/lhc/.

    The conditions are now established to allow testing of all magnets in this sector to their ultimate performance.


    I am not going to go into the relevance here but to describe how "I speculate" the "extra energy is lost" while delivering the expected results of the LHC microscope in it's efforts.

    This is based on the Navier–Stokes existence and smoothness that "may be" responsible for this loss. The understanding as I have come to see it is that the QGP by it's very nature is conclusively reached it total state, and that by reaching it, it brought in line, with the Superconductors relations. The principal here that a relativistic conditon is arrived at in the super fluid condition that I perceive is, in relation to the aspect of the Helium used to cool the LHC

    Navier-Stokes Equation

    Waves follow our boat as we meander across the lake, and turbulent air currents follow our flight in a modern jet. Mathematicians and physicists believe that an explanation for and the prediction of both the breeze and the turbulence can be found through an understanding of solutions to the Navier-Stokes equations. Although these equations were written down in the 19th Century, our understanding of them remains minimal. The challenge is to make substantial progress toward a mathematical theory which will unlock the secrets hidden in the Navier-Stokes equations.

    SuperFluids

    MIT physicists create new form of matter by Lori Valigra, Special to MIT News Office June 22, 2005

    A superfluid gas can flow without resistance. It can be clearly distinguished from a normal gas when it is rotated. A normal gas rotates like an ordinary object, but a superfluid can only rotate when it forms vortices similar to mini-tornadoes. This gives a rotating superfluid the appearance of Swiss cheese, where the holes are the cores of the mini-tornadoes. "When we saw the first picture of the vortices appear on the computer screen, it was simply breathtaking," said graduate student Martin Zwierlein in recalling the evening of April 13, when the team first saw the superfluid gas. For almost a year, the team had been working on making magnetic fields and laser beams very round so the gas could be set in rotation. "It was like sanding the bumps off of a wheel to make it perfectly round," Zwierlein explained.

    "In superfluids, as well as in superconductors, particles move in lockstep. They form one big quantum-mechanical wave," explained Ketterle. Such a movement allows superconductors to carry electrical currents without resistance.

    The MIT team was able to view these superfluid vortices at extremely cold temperatures, when the fermionic gas was cooled to about 50 billionths of one kelvin, very close to absolute zero (-273 degrees C or -459 degrees F). "It may sound strange to call superfluidity at 50 nanokelvin high-temperature superfluidity, but what matters is the temperature normalized by the density of the particles," Ketterle said. "We have now achieved by far the highest temperature ever." Scaled up to the density of electrons in a metal, the superfluid transition temperature in atomic gases would be higher than room temperature.


    Now it is important that giving the circumstance with which I hold these views "to be the decomposable limits" on the collision process itself, the, "value of the decay" in initiating such a phase, it was important to me to explain how I thought new physics is to be established around our current value thinking in relation to the universe.

    This picture shows a classical vortex (Hurricane Isabel in summer 2003, NASA image ISS007E14887).

    So while we had done our research on the values of what a scientist means in regards to an image search on Google, I thought what better way but to introduce my efforts, as well to listing the essence of my understanding, by showing posts, that coincided with the prospective that I was and am establishing as a value in context of the acceleration of this universe.

    It is to establish how this universe can contain an "relativistic interpretation" about the "beginning and end" contained in this universe and was of some interest to me, as I charted the course and terms related to the searches for the microscopic blackhole holes and what it can ensue in it's decay.

    A condensate of Fermion pairs (red) is trapped in the waist of a focussed Laser beam (pink). Two additional Laser beams (green) rotate around the edges to stir the condensate. Current-carrying coils (blue) generate the magnetic field used for axial confinement and to tune the interaction strength by means of a Feshbach resonance. After releasing the atomic cloud from the electromagnetic trap, the cloud expands ballistically and inverts its aspect ratio. Resonant absorption imaging yields a density profile of the atomic cloud containing vortices.


    It was important that such an analogy serve to express that "what has always been" can move from one universe to another, by the interpretation of the false vacuum to the true and, by introducing this element in consideration of the lengths such a collision process can be taken too.

    This has always been of some issue to me about what can take our universe to a "zero point entropy consideration" while understanding that the larger context showing representational for this universe, holds an interesting view, that while large can be taken onto the environs that collisions processes may hold for further introspective views.

    Now I have been watching the interpretations of Inductive and Deductive valuations over at Bee's held in conversation of theBackreaction: The Block Universe and I am not totally satisfied that either party has really explained what "infinite regress means" while looking to the "decomposable element" with which I hold mathematics as a necessary understanding, while we look to explain the very principals and nature of this universe, and it's accelerations currently established.

    Just having established a link with backreactions block universe posting with this article, I see Phil has explained nicely what the process is to me, and how "infinite regress and decomposable element" are held in the same breathe. I have to give by example my understanding so that one sees this is not a "vacant thought process" with which I work.

    While one might think I belittle the process it is wholly by my environmental scanning and integrating view that I was able to deduce in regards to the "Plane of Simultaneity" an of "much greater depth" then what is assumed there at Backreaction.

    This statement of "much greater depth," must be seen in relation to what Tom Levenson in his first introductory article on Cosmic Variance, is revealing by, "Inverse Square law" introduction.

    Tom Levenson:....what would make current physical ideas as powerful and as intelligibly strange as Newton was able to make his story of a comet travelling from and to distances with out limit?


    Shadows, are the contention with which "cave views are enlisted" and remain, "in the the box thinkers." You had to know by my reply, that this depth was beyond the 3+1 view held , and pushing further, is the scope and intention of being lead by science, whether one thinks so or not by my representations.

    That, "in the box thinking" has never left the backreaction interpretations. Phenomenological order, must be introduced, in order to establish current scientific experiments with the actual hypothetical processes, where, such a hypothesis will take you too, leading from, "infinite regress and decomposable limits of definition." at the peak of this Aristotlean Arche. What is Self-Evident.

    Savas Dimopoulos:At close encounter the particles can exchange gravitons via the two extra dimensions, which changes the force law at very short distances. 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.
    See:Newton's inverse-square (1/r2) law

    This is a inductive/deductive stance that a person assumes in moving through science, as I understood it.

    It is important that this process be established and identified as I reveal the thinking about the current state of the universe and how LHC experimental development, are giving new light, to Galactic communications. Microscopic Blackhole decay.

    Also too,

    The standard model of particle physics is a self-contained picture of fundamental particles and their interactions. Physicists, on a journey from solid matter to quarks and gluons, via atoms and nuclear matter, may have reached the foundation level of fields and particles. But have we reached bedrock, or is there something deeper? Savas Dimopoulos


    Such a question sets the pace for understanding the limits with which we have contained ourselves in regard to General Relativity, and yet, to think that such a result of General Relativity could have ever been embedded as a "beginning and end" in the explanation of the universe, is introduced by time reversals and such?

    Polar Flips

    Sometimes it is necessary to see the deep impact a thought could have as we try to understand the implications of a "sphere dropped in a viscously liquid" that we might find another correlation in how we see the photon affected in the gravitational field. Can we grasped the feeling illicitated to say we have some what of a deep impact in remembering to think the strange world of fluids could entertain us?

    Stokes' law

    In 1851, George Gabriel Stokes derived an expression for the frictional force exerted on spherical objects with very small Reynolds numbers (e.g., very small particles) in a continuous viscous fluid by solving the small fluid-mass limit of the generally unsolvable Navier-Stokes equations:



    where:

    is the frictional force,
    r is the Stokes radius of the particle,
    η is the fluid viscosity, and
    is the particle's speed.

    If the particles are falling in the viscous fluid by their own weight, then a terminal velocity, also known as the settling velocity, is reached when this frictional force combined with the buoyant force exactly balance the gravitational force. The resulting settling velocity is given by:



    where:

    Vs is the particles' settling velocity (cm/sec) (vertically downwards if ρp > ρf, upwards if ρp < ρf),
    r is the Stokes radius of the particle (cm),
    g is the standard gravity (cm/sec2),
    ρp is the density of the particles (g/cm3),
    ρf is the density of the fluid (g/cm3), and
    η is the fluid viscosity (dyne sec/cm2).


    Why are Planets Round?

    Q9:
    Would these fluids act differently on the Moon and at (on) different gravities


    I was loosing the train of thought within this post, and then the thought occurred me.

    Why are planets round. This is a "general question" which leads to how we see the formation of the planets?

    "isostatic adjustment"

    Start there. We also know what a "sphere of water" looks like in space?

    While the sphere was being thought of in regards to Stokes's Theorem, I was also thinking of the earth in relation to how we see gravity in regards to the earth already formed. The vicissitude, in which the earth exists within the cosmos. The moon.

    The rotating superfluid gas of fermions is pierced with the vortices, which are like mini-tornadoes. Image / Andre Schirotzek, MIT

    Bose-Einstein condensation of pairs of fermions that were bound together loosely as molecules was observed in November 2003 by independent teams at the University of Colorado at Boulder, the University of Innsbruck in Austria and at MIT. However, observing Bose-Einstein condensation is not the same as observing superfluidity. Further studies were done by these groups and at the Ecole Normale Superieure in Paris, Duke University and Rice University, but evidence for superfluidity was ambiguous or indirect.

    The superfluid Fermi gas created at MIT can also serve as an easily controllable model system to study properties of much denser forms of fermionic matter such as solid superconductors, neutron stars or the quark-gluon plasma that existed in the early universe.


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

    See here for more on Attributes of Superfluids

    It is very possible that the information is inundating my thinking here yet without considering the context of the super fluid what requirements would fit the idea that earth is relevant when it comes to the molten core? Or how you see the magnetic field shifting in relation to the poles?

    Thus, water is "thin", having a lower viscosity, while vegetable oil is "thick" having a higher viscosity. All real fluids (except superfluids) have some resistance to shear stress, but a fluid which has no resistance to shear stress is known as an ideal fluid or inviscid fluid (Symon 1971).


    I am quickly posting this and will have more to add. I wanted to speak directly to the idea of the super fluid. How the "irrotational value of the perfect fluid as a whole," could have it's leakages to the surface of the earth, as small vortices created.



    This computer simulation shows the Earth's interior as its magnetic field reverses, perhaps because of changes in the flow of molten iron in the core. Deep inside the Earth, the magnetic field arises as the fluid core oozes with hot currents of molten iron and this mechanical energy gets converted into electromagnetism. It is known as the geodynamo. In a car's generator, the same principle turns mechanical energy into electricity.

    No one knows precisely why the field periodically reverses, but scientists say the responsibility probably lies with changes in the turbulent flows of molten iron, which they envision as similar to the churning gases that make up the clouds of Jupiter.

    In theory, a reversal could have major effects because over the ages many aspects of nature and society have come to rely on the field's steadiness.




    Quasar posted a comment there that immediately made me think what the topic could mean in relation to the post he was commenting on. I thought of the earth's core as the subject was related, and thought how nice it would be to have such a "cylindrical channel that goes from pole to pole?"

    Well the viscosity of the fluid as it traverses this cylinder would give some nature to the charge as it passes through? I do not think it could be that simple, if we thought the iron molten as the viscosity had a direct relation to what we know of our magnetic field? We know the earth core is not so cylindrical, that we could the attribute of the superfluid in this case while looking at the iron molten lava

    So is it the iron in particular that gives us our strength based on it's fluid's nature?

    These changes in Earth’s magnetic fields from 1980 to 2000 may be harbingers of a shift in the magnetic poles

    Relativistic Fluid Dynamics

    The Navier-Stokes equations


    A bubble is a minimal-energy surface
    The Navier-Stokes equations, named after Claude-Louis Navier and George Gabriel Stokes, are a set of equations that describe the motion of fluid substances such as liquids and gases. These equations establish that changes in momentum in infinitesimal volumes of fluid are simply the product of changes in pressure and dissipative viscous forces (similar to friction) acting inside the fluid. These viscous forces originate in molecular interactions and dictate how viscous a fluid is. Thus, the Navier-Stokes equations are a dynamical statement of the balance of forces acting at any given region of the fluid.




    In educating myself I learnt to trust my intuition when it comes to defining the basis of "new physics" that was to emerge. As well as, the new particle manifestation that would arise from "specific points" on interaction. What was suppose to be our starting point. This is really difficult for me to put into words, yet, if you knew that there was a "change over/cross over point" and how was this defined? It seemed to me, we had to have a place that would do this.

    A more fundamental property than the disappearance of viscosity becomes visible if superfluid is placed in a rotating container. Instead of rotating uniformly with the container, the rotating state consists of quantized vortices. That is, when the container is rotated at speed below the first critical velocity (related to the quantum numbers for the element in question) the liquid remains perfectly stationary. Once the first critical velocity is reached, the superfluid will very quickly begin spinning at the critical speed. The speed is quantized - i.e. it can only spin at certain speeds.


    "Nothing" is difficult to talk about, and "empty space" is not really empty. So to think "nothing" is a very hard one for me to grasp. If one thinks about what "sprang into being" I of course had to find this "place of traversing" from "one state of being" to another. What things help us to define the nature of that point?



    Example of the viscosity of milk and water. Liquids with higher viscosities will not make such a splash.

    Viscosity is a measure of the resistance of a fluid to deform under shear stress. It is commonly perceived as "thickness", or resistance to flow. Viscosity describes a fluid's internal resistance to flow and may be thought of as a measure of fluid friction. Thus, water is "thin", having a lower viscosity, while vegetable oil is "thick" having a higher viscosity. All real fluids (except superfluids) have some resistance to shear stress, but a fluid which has no resistance to shear stress is known as an ideal fluid or inviscid fluid (Symon 1971).


    I used the question mark not to befuddle those that read here or sanction any post to some idea about what the title following with a question mark, is worth so many points on the "flowery scale."

    On the other hand, gravity in the form of curved space would permeate the whole bulk of the higher dimensional spacetime …. Stephen Hawking1


    I shall have to define "flowery scale" sometime, but I would rather not give any credit to those who hold a position in science who have categorize people according to that same point system. Oh and please, do not consider the flowers less then what I hold as of high value in these "maturations" to be thought less then either.



    While we had been witness to the collider experiments we were also quite aware that that such events had to be taking place with earth, from event sources released in space.

    Relativistic Fluid Dynamics: Physics for Many Different Scales-Nils Andersson

    In writing this review, we have tried to discuss the different building blocks that are needed if one wants to construct a relativistic theory for fluids. Although there are numerous alternatives, we opted to base our discussion of the fluid equations of motion on the variational approach pioneered by Taub [108] and in recent years developed considerably by Carter [17, 19, 21]. This is an appealing strategy because it leads to a natural formulation for multi-fluid problems. Having developed the variational framework, we discussed applications. Here we had to decide what to include and what to leave out. Our decisions were not based on any particular logic, we simply included topics that were either familiar to us, or interested us at the time. That may seem a little peculiar, but one should keep in mind that this is a “living” review. Our intention is to add further applications when the article is updated. On the formal side, we could consider how one accounts for elastic media and magnetic fields, as well as technical issues concerning relativistic vortices (and cosmic strings). On the application side, we may discuss many issues for astrophysical fluid flows (like supernova core collapse, jets, gamma-ray bursts, and cosmology).

    In updating this review we will obviously also correct the mistakes that are sure to be found by helpful colleagues. We look forward to receiving any comments on this review. After all, fluids describe physics at many different scales and we clearly have a lot of physics to learn. The only thing that is certain is that we will enjoy the learning process!


    Spacetime Curvatures

    Flat space time? The thought there are strong gravitational forces at work and where are these located? Can there "be" amidst this strong curvature, the idea that a super fluid born, would have a place where a state of inertia could exist? I thought quickly of what happens when the blackhole collapses and what could come of it?

    Of course this concept of inertia is strong in my mind but would need better clarifications as I am relaying it here in this circumstance.

    But looking for these locations in Lagrangian views of the Sun Earth relation, it seemed viable to me that such a state could have gone from a very strong gravitational inclination( our suns, increase temperatures of the collapsing blackhole) to one that is "very free" and "not flat" but would allow information both ways(from before to now) to be traversed, as if in a jet or cylinder. So that the space around it would be expression not only the earlier constituents of the universe before this translation but manifest into the new physics with which would motive this universe, new particle manifestation, from what did not exist before.

    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.


    Photo credit: Lloyd DeGrane/University of Chicago News Office
    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.


    Getty Images
    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.

    Beyond Spacetime?

    As well as bringing the accelerator's counter-rotating beams together, LHC insertion magnets also have to separate them after collision. This is the job of dedicated separators, and the US Brookhaven Laboratory is developing superconducting magnets for this purpose. Brookhaven is drawing on its experience of building the Relativistic Heavy Ion Collider (RHIC), which like the LHC is a superconducting machine. Consequently, these magnets will bear a close resemblance to RHIC's main dipoles. Following a prototyping phase, full-scale manufacture has started at Brookhaven and delivery of the first superconducting separator magnets to CERN is foreseen before the end of the year.





    Now some people do not like "alternate views" when looking at Sean's picture. But if you look at it, then look at the picture below, what saneness, sameness, could have affected such thinking?

    Lisa Randall:
    "You think gravity is what you see. We're always just looking at the tail of things."





    So we look for computerized versions to help enlighten. To "see" how the wave front actually embues circumstances and transfers gravitonic perception into other situations.



    Was this possible without understanding the context of the pictures shared? What complexity and variable sallows us to construct such modellings in computers?



    Okay so you know now that lisa Randall's picture was thrown inhere to hopefully help uyou see what I am saying about gravitonic consideration.

    Anything beyond the spacetime we know, exists in dimensional perspectives, and the resulting "condensative feature" of this realization is "3d+1time." The gravitonic perception is "out there?" :)

    Attributes of the Superfluids

    Now it is with some understanding that the "greater energy needed" with which to impart our views on let's say "reductionism" has pointed us in the direction of the early universe.

    So we say "QGP" and might say, "hey, is there such a way to measure such perspectives?" So I am using the graph, to point you in the right direction.



    So we talk about where these beginnings are, and the "idea of blackholes" makes their way into our view because of th reductionistic standpoint we encountered in our philosophical ramblings to include now, "conditions" that were conducive to microstate blackhole creation.

    The energy here is beyond the "collidial aspects" we encounter, yet, we have safely move our perceptions forward to the QGP? We have encounter certain results. You have to Quantum dynamically understand it, in a macro way? See we still talk about the universe, yet froma microscopic perception.

    Let's move on here, as I have.

    If you feel it too uncomfortable and the "expanse of space quantumly not stimulating" it's okay to hold on to the railings like I do, as I walked close to the "edge of the grand canyon."

    So here we are.

    I gave some ideas as to the "attributes of the superfluids" and the history in the opening paragraph, to help perspective deal with where that "extra energy has gone" and how? So you look for new physics "beyond" the current understanding of the standard model.

    So, it was appropriate to include the graviton as a force carrier? Qui! NOn?
