Angels and Demons on a Pinhead

"Observations always involve theory."Edwin Hubble
Curvature Parameters

Of course I had to point to the cosmological understanding that took us to this "geometrical understanding of things that are large." But this is to be short, while I crunch the thoughts of the process to the pinhead. You can follow the "picture links" and learn more on your own time.


Calabi-Yau manifold (3D projection made with Mathematica)-
In either case, gravity acting in the hidden dimensions affects other non-gravitational forces such as electromagnetism. In fact, Kaluza and Klein's early work demonstrated that general relativity with five large dimensions and one small dimension actually predicts the existence of electromagnetism. However, because of the nature of Calabi-Yau manifolds, no new forces appear from the small dimensions, but their shape has a profound effect on how the forces between the strings appear in our four dimensional universe. In principle, therefore, it is possible to deduce the nature of those extra dimensions by requiring consistency with the standard model, but this is not yet a practical possibility. It is also possible to extract information regarding the hidden dimensions by precision tests of gravity, but so far these have only put upper limitations on the size of such hidden dimensions.


How many would have thought that such a micro-perspective could have been ever be taken down to "this level" and found an analogy that is suitable? You needed something more here to consider, yet, I will call it "angel and demons" for those who like the mystery.

I will try and spell out what is happening at such a microperspective level. You might wonder, how did such ideas become what is, "the good and evil of the world" is really a part of the dynamics that we see geometrically enhanced, as we delve ever deeper into this mystery of reductionism and such. On how, we may look at cosmology that "is different" with this perspective.

Energy "is" Gravitationally Related

At some point, those considering "all this energy" and the way reduction is assigned to the energy at all levels, what shall any calorimetric pick up as such collision processes seek to define "every contact" as we want to "map the pinhead" accordingly?

Lubos Motl saids that he sees the relation to such dynamical situations as "fruitful research" toward the understanding of the cosmological descriptions implied from such micro states. To have it listed according to a "geometrical perspective" we might be able to assign each universe? Okay! He did not say that exactly, so check into his blog entry for an update.

I'd like to thank Quasar9 for reporting on this as well.

Orbitals



My thoughts have been there toward reductionism's more cosmological counterpart for some time now. So I enjoy, that the views that I have had about the microperspective have indeed been sanctioned at some science level according to the scientist in the know. Yes, I can prove my thoughts here for you, so you know what I mean.


The star Eta Carina is ejecting a pair of huge lobes that form a "propeller" shape. Jet-like structures are emanating from the center (or "waist"), where the star (quite small on this scale) is located.


Now it is indeed a "greater depth of perception" that asks us to delve into the microperspective of string world. How is it the cosmological world can have such similarities, while the story of the Calabi Yau, makes itself a headlight news current in the research of string theory?

The First Few Microseconds, by Michael Riordan and Willaim A. Zajc
During those early moments, matter was an ultrahot, superdense brew of particles called quarks and gluons rushing hither and thither and crashing willy-nilly into one another. A sprinkling of electrons, photons and other light elementary particles seasoned the soup. This mixture had a temperature in the trillions of degrees, more than 100,000 times hotter than the sun's core.

    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.


    Diagram of the Lagrange Point gravitational forces associated with the Sun-Earth system.


    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.

    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.

    The Geometrics Behind the Supernova and it's History



    It is not always easy for people to see what lies behind the wonderful beauty of images that we take from the satellite measures of space, and it's dynamical events illustrated in Cassiopeia A. There before you is this majestic image of beauty, as we wonder about it's dynamics.


    These Spitzer Space Telescope images, taken one year apart, show the supernova remnant Cassiopeia A (yellow ball) and surrounding clouds of dust (reddish orange). The pictures illustrate that a blast of light from Cassiopeia A is waltzing outward through the dusty skies. This dance, called an "infrared echo," began when the remnant erupted about 50 years ago. Image credit: NASA/JPL-Caltech/Univ. of Ariz.
    An enormous light echo etched in the sky by a fitful dead star was spotted by the infrared eyes of NASA's Spitzer Space Telescope.

    The surprising finding indicates Cassiopeia A, the remnant of a star that died in a supernova explosion 325 years ago, is not resting peacefully. Instead, this dead star likely shot out at least one burst of energy as recently as 50 years ago.



    How is it such information arrives to us, and we would have to consider the impulse's behind such geometrical explanations. Which we are lucky to see in other ways. So, of course we needed to see the impulse as dynamically driven by the geometrical inclinations of that collapse, and all it's information spread outward by the description in images painted.

    This image is from a computer simulation of the beginning of a gamma-ray burst. Here we see the jet 9 seconds after its creation at the center of a Wolf Rayet star by the newly formed, accreting black hole within. The jet is now just erupting through the surface of the Wolf Rayet star, which has a radius comparable to that of the sun. Blue represents regions of low mass concentration, red is denser, and yellow denser still. Note the blue and red striations behind the head of the jet. These are bounded by internal shocks.


    If I had approached you early on and suggested that you look at "bubble geometrodynamics" would it have seemed so real that I would have presented a experiment to you, that would help "by analogies" to see what is happening? Might I then be called the one spreading such information that it was not of value to scientists to consider, that I was seeing in ways that I can only now give to you as example? What science has done so far with using the physics with cosmological views?


    Image Credit: NASA/JPL-Caltech/STScI/CXC/SAO
    This stunning false-color picture shows off the many sides of the supernova remnant Cassiopeia A, which is made up of images taken by three of NASA's Great Observatories, using three different wavebands of light. Infrared data from the Spitzer Space Telescope are colored red; visible data from the Hubble Space Telescope are yellow; and X-ray data from the Chandra X-ray Observatory are green and blue.

    Located 10,000 light-years away in the northern constellation Cassiopeia, Cassiopeia A is the remnant of a once massive star that died in a violent supernova explosion 325 years ago. It consists of a dead star, called a neutron star, and a surrounding shell of material that was blasted off as the star died. The neutron star can be seen in the Chandra data as a sharp turquoise dot in the center of the shimmering shell.


    In this image above we learn of what manifests in "jet production lines," and such examples are beautiful examples to me of what the geometrics are doing. You needed some way to be able to explain this within context of the universe's incidences "as events." We say this action is one with which we may speak to this "corner of the universe." Yet it is very dynamical in it's expression as we see it multiplied from various perspectives.


    The structure of Model J32 as the jet nears the surface 7820 seconds after core collapse.


    So by experiment(?) I saw such relations, but what use such analogies if they are laid waste to speculation that what was initiated such ideas had been the inclination of geometrics detailed as underlying the basis of all expression as an example of some non euclidean views of Riemann perspectives leading shapes and dynamics of our universe by comparison within the local actions of stars and galaxies?

    Gamma Rays?



    So we get this information in one way or another and it was from such geometrical impulse that such examples are spread throughout the universe in ways that were not understood to well.

This so-called "afterglow" gave an accurate position of the burst on the sky and enabled the deep optical observations made by ground-based observatories and the Hubble Space Telescope.

    A year ago scientists thought they had figured out the nature of gamma-ray bursts. They signal the birth of black holes and traditionally, fall into one of two categories: long or short. A newly discovered hybrid burst has properties of both known classes of gamma-ray bursts yet possesses features that remain unexplained.

    The long bursts are those that last more than two seconds. It is believed that they are ejected by massive stars at the furthest edge of the universe as they collapse to form black holes.


    So looking back to this timeline it is important to locate the ideas spread out before us. Have "some place" inclusive in the reality of that distance from the origins of the stars of our earliest times. 13.7 billions years imagine!


    Fig. 1: Sketchy supernova classification scheme
    A supernova is the most luminous event known. Its luminosity matches those of whole galaxies. The name derives from the works of Walter Baade and Fritz Zwicky who studied supernovae intensively in the early 1930s and used the term supernova therein.
    Nowadays supernova is a collective term for different classes of objects, that exhibit a sudden rise in luminosity that drops again on a timescale of weeks.
    Those objects are subdivided into two classes, supernovae of type I or II (SNe I and SNe II). The distinguishing feature is the absence or the presence of spectral lines of hydrogen. SNe I show no such lines as SNe II do. The class of SNe I is further subdivided in the classes a, b and c. This time the distinguishing feature are spectral features of helium and silicon. SN Ia show silicon features, SN Ib show helium but no silicon features and SN Ic show both no silicon and no helium spectral features.
    The class of SN II is further subdivided in two classes. Those are distinguished by the decline of the lightcurve. Those SN II that show a linear decline are named SN II-L and those that pass through a plateau-phase are referred to as SN II-P.



    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?

    This artist's timeline chronicles the history of the universe, from its explosive beginning to its mature, present-day state.

    Our universe began in a tremendous explosion known as the Big Bang about 13.7 billion years ago (left side of strip). Observations by NASA's Cosmic Background Explorer and Wilkinson Anisotropy Microwave Probe revealed microwave light from this very early epoch, about 400,000 years after the Big Bang, providing strong evidence that our universe did blast into existence. Results from the Cosmic Background Explorer were honored with the 2006 Nobel Prize for Physics.

    A period of darkness ensued, until about a few hundred million years later, when the first objects flooded the universe with light. This first light is believed to have been captured in data from NASA's Spitzer Space Telescope. The light detected by Spitzer would have originated as visible and ultraviolet light, then stretched, or redshifted, to lower-energy infrared wavelengths during its long voyage to reach us across expanding space. The light detected by the Cosmic Background Explorer and the Wilkinson Anisotropy Microwave Probe from our very young universe traveled farther to reach us, and stretched to even lower-energy microwave wavelengths.

    Astronomers do not know if the very first objects were either stars or quasars. The first stars, called Population III stars (our star is a Population I star), were much bigger and brighter than any in our nearby universe, with masses about 1,000 times that of our sun. These stars first grouped together into mini-galaxies. By about a few billion years after the Big Bang, the mini-galaxies had merged to form mature galaxies, including spiral galaxies like our own Milky Way. The first quasars ultimately became the centers of powerful galaxies that are more common in the distant universe.

    NASA's Hubble Space Telescope has captured stunning pictures of earlier galaxies, as far back as ten billion light-years away.


    Would sort of set up the challenge?

    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.

    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


    A simulation of large-scale structure
    formation
    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?

    Discovering the Quantum Universe

    -----------------------------------------------------

    Right now is a time of radical change in particle physics. Recent experimental evidence demands a revolutionary new vision of the universe. Discoveries are at hand that will stretch the imagination with new forms of matter, new forces of nature, new dimensions of space and time. Breakthroughs will come from the next generation of particle accelerators — the Large Hadron Collider, now under construction in Europe, and the proposed International Linear Collider. Experiments at these accelerators will revolutionize your concept of the universe.

    Finding a heavenly key to climate change

    Researchers at the European Organization for Nuclear Research (Cern) in Geneva are looking at how radiation from outer space could be affecting our environment.

    A new cutting:edge experiment aims to discover how exactly cosmic rays and the Sun may influence the formation of low:level clouds, and possibly climate change.

    More than two centuries ago, the British Astronomer Royal William Herschel noted a correlation between sunspots ? an indicator of solar activity : and the price of wheat in England. He suggested that when there were few sunspots, prices rose.

    However, up until recently, there was little to back up this hypothesis. Today, inside an unassuming ? some would say decrepit:looking ? building at Cern, the Cloud (Cosmics Leaving OUtdoor Droplets) experiment might help explain how the Sun affects the climate.

    NASA Schedules Dark Energy Discovery Media Teleconference

    NASA will host a media teleconference with Hubble Space Telescope astronomers at 1 p.m. EST Thursday, Nov. 16, to announce the discovery that dark energy has been an ever-present constituent of space for most of the universe's history.

    Back to the Beginning of Time



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

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


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

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




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

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

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

    The James Webb Space Telescope (JWST) is a large, infrared-optimized space telescope, scheduled for launch in 2013. JWST will find the first galaxies that formed in the early Universe, connecting the Big Bang to our own Milky Way Galaxy. JWST will peer through dusty clouds to see stars forming planetary systems, connecting the Milky Way to our own Solar System. JWST's instruments will be designed to work primarily in the infrared range of the electromagnetic spectrum, with some capability in the visible range.

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

    JWST Science

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


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

    The Dark Ages of the UniverseBy Abraham Loeb

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


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

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

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

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

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

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

    Doppelgänger Favors Oscillate

    "Observations always involve theory."Edwin Hubble


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

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

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

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


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

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


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

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


    Right Handed Neutrino

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

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


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

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

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

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

    Central Theme is the Sun



    A lot of times people do not understand the effects something can have and after we see these effects, we wonder how did we ever miss the importance of what layed underneath this process in Physics.


    Richard Feynman-Dancing With Neutrinos-Nova



    Much as we looked at the stars above, the views became much clearer with hubble and such, that we see the depth is necessary as we quantum dynamically learn to see with a greater comprehension.

    481 MeV muon neutrino (MC) produces 394 MeV muon which later decays at rest into 52 MeV electron. The ring fit to the muon is outlined. Fuzzy electron ring is seen in yellow-green in lower right corner. This is perspective projection with 110 degrees opening angle, looking from a corner of the Super-Kamiokande detector (not from the event vertex). Option -show_non_hit was used to show all PMTs. Color corresponds to time PMT was hit by Cerenkov photon from the ring. Color scale is time from 830 to 1816 ns with 15.9 ns step. The time window was widened from default to clearly show the muon decay electron in different color. In the charge weighted time histogram to the right two peaks are clearly seen, one from the muon, and second one from the delayed electron from the muon decay. Size of PMT corresponds to amount of light seen by the PMT. PMTs are drawn as a flat squares even though in reality they look more like huge flattened golden light bulbs.


    Now it is important to me that when I seen the relationships of physics extolling itself in nature, I wanted to understand how this evidence came to be. But, before I lay what nature has shown me, I wanted to explain a little further what I am starting put together in my head, about what has become common in our understanding, was not easily so from a theoretical/concept/idea standpoint. That it was indeed "progressive/reductionistic" as our views became ever more progressive as we see the same picture of the cosmo(astrophysics) in an ever widening view of understanding.

    The neutrino detector for the Super-Kamiokande experiment in Japan contains ultrapure water surrounded by an array of thousands of photo-tubes, arranged to catch the flashes of light from neutrino interactions in the water. In 1998, researchers at "Super-K" found evidence for a small mass for neutrinos coming to earth from particle interactions in cosmic rays. If neutrinos, until recently thought to be massless, actually do have a mass, the implications will be profound, not only for particle physics but for astronomy and cosmology. At right is the MINOS collaboration at the Department of Energy’s Fermilab, before a slice of the 10,000-ton detector they will build to capture neutrino interactions. The MINOS experiment will use beams of accelerator-produced neutrinos by Fermilab's Tevatron to investigate neutrino mass.


    Now the lesson above is quite simplistic in the sense that what was once held in theoretical views could/would have made it's way into the depths of how we see things now in nature. So in having understood that process, I wanted to show two more that you might be interested in?

    The picture below here is what I see from my backyard when mist and rain has fallen.



    So here you have it. A couple of views of nature that have been exemplifed in our search for understanding. What does this all reveal to you? Well, that's the continung saga of what the depth of perception has endowed all us human beings, as we look ever deeper into the nature of the cosmo, and the beginning of this universe.

    While we had been given the Sun to look at in one of it's diverse ways, I wanted and did show that meeting the views of how we look at things. That it had been extended, by understanding the "valuation of the energy" as it has ensued from the very heart of what that burning sun is. How we gain immediate results, not ony in the particle showers, but of what evidence we have lain before us, as the physical outcome, as we look from space, and how, we look from earth.
