Without Gravitational Waves, Spacetime is Flat?

I know it is very difficult for some people to understand this translation to harmonical expressions(any horizon and what is to lie beyond?) and the way in which we would percieve this dynamcial nature, using the expressions of non-Euclidean geometries?



We understood this creation of positive and negtaive in context of each other did we?

Riemannian Geometry, also known as elliptical geometry, is the geometry of the surface of a sphere. It replaces Euclid's Parallel Postulate with, "Through any point in the plane, there exists no line parallel to a given line." A line in this geometry is a great circle. The sum of the angles of a triangle in Riemannian Geometry is > 180°.



It is a strange thing to wonder how the heck one get's to translating harmonical oscillations in context of what we see expounded by Taylor and Hulse. To understand that at some point, the rotation around each other in distance, will decrease in time, and the oscillations will increase? What does this signal?:)



You do not discard thnking about the cosmological nature, methods, that have been used to orientate the world view in such a way, where all of a sudden the complexity of this dynamical nature has moved your thinking to strength and weakness of those same gravitational wave explanations.

Working closely with the experimental group, we use astrophysical, particle physics and superstring theory combined with observations to study gravitation and the origin and evolution of our universe.

The beautiful consistency of the cosmological tests with the Lambda CDM theory for structure formation maybe is particularly impressive to me because I spent so much of the last 15 years studying alternatives; you can trace through astro-ph my history of proposals that were viable when submitted but soon ruled out by advances in measurements of the angular distribution of the 3K thermal background radiation. But the constraints from the cosmological tests are not yet much more numerous than the assumptions in Lambda CDM and related models; it's too soon to declare closure of the cosmological tests.

Great Circles

You would think with this uncertainty, that I had answered my own question about what Peter Woit has done, in terms of offering some substantiative understanding for rejection of string theory. But it doesn't.

Sometimes we rely on the roads taken by Webber, Wheeler and Kip, and those who understood well the consequence of gravitational considerations, to further enhance these specualtive journies and to better explore the bulk that might have varying attributes?

The theory of relativity predicts that, as it orbits the Sun, Mercury does not exactly retrace the same path each time, but rather swings around over time. We say therefore that the perihelion -- the point on its orbit when Mercury is closest to the Sun -- advances

.

What am I saying here? You mean, that in the primordial understanding there are extensions of what could be thought of in terms of strength and weakness, in gravitational terms? I would most certainly like to see the light shining in these circumstances.:)But like anything of course, we like to LIGOlize these terms for further consideration. Don't we?

Let us see how these great physicists used harmonic oscillators to establish beachheads to new physics.

Bubble world

Using a rubber band analogy over top of a ball is a interesting way to approach the circle used, and the energy determinations found of value in calculating 1r radius(KK Tower) of that same circle, as you move to the top. But if you move it along a length and you find that you can calculate the difference in this length by the changes in the energy valuations?



It’s how you look at this space inside the bubble versus outside the bubble. John Baez might look at it on the outside as such above recognizing well the lines connectin flip and change depending on the energy demonstrated in a quantum grvaity model? While the inside of the bubble is dictated by some other means of interpretation? From the inside, a soccer ball universe(poincare structure) would seem so appropriate but here Max Tegmark has answer this view, through Wmap views?



For me, I would look at the surface of the bubble and the rainbows that could shimmer across it’s surface. We would be defining the shape of the bubble in a way we had not considered before? Moving sound in analogy to the world of gravitational considerations how would this view be considered now in context of bubble technologies?



Using circles as energy determination seems viable as they travel the length, but it becomes much more diffiuclt when you are trying to merge these bubbles, it looks discrete, when the lines are joining while curvature defines the connection between the two? You see the bubbles have a outer structure. As these circles merge, it is not past the knowledge to coisder that the path integral approach is being exemplified.

Running contrary to the view of bubble world, the images of a vast systems of cosmic strings that would flash across a universe may seem very interesting as I gaze from artistic perception about the flash of a lightening strike? That ignited new possibilties into expression, new life in the universe?

Quantum gravity, the as yet unconsummated marriage between quantum physics and Einstein's general relativity, is widely (though perhaps not universally) regarded as the single most pressing problem facing theoretical physics at the turn of the millennium. The two main contenders, ``Brane theory/ String theory'' and ``Quantum geometry/ new variables'', have their genesis in different communities. They address different questions, using different strategies, and have different strengths (and weaknesses).

What is Quantum Gravity?

Quantum gravity is the field devoted to finding the microstructure of spacetime. Is space continuous? Does spacetime geometry make sense near the initial singularity? Deep inside a black hole? These are the sort of questions a theory of quantum gravity is expected to answer. The root of our search for the theory is a exploration of the quantum foundations of spacetime. At the very least, quantum gravity ought to describe physics on the smallest possible scales - expected to be 10-³⁵ meters. (Easy to find with dimensional analysis: Build a quantity with the dimensions of length using the speed of light, Planck's constant, and Newton's constant.) Whether quantum gravity will yield a revolutionary shift in quantum theory, general relativity, or both remains to be seen.

Cosmic Strings Revisited

This high energy consideration does this, as well as directs the mind to consider the cosmological evidence that lays before us now. Dimensional interpretation, has to have it's basis contained within this whole view. With the cosmic string we are only defining a period of time with in the whole expression of this same universe? This would inlcude Pre bang scenarios and how these must be included.

Cosmic Superstrings Revisitedby Joseph Polchinski

Thus far we have quoted upper bounds, but there are possible detections of strings via gravitational lensing. A long string will produce a pair of images symmetric about an axis, very different from lensing by a point mass. Such an event has been reported recently

Universe INside a Box




Lens candidates in the Capodimonte Deep Field in vicinity of the CSL1 object by Sazhin M.V.1, Khovanskaya O.S.1, Capaccioli M.2,3, Longo G.3,4,Alcal´a J.M. 2, Silvotti R.2, Pavlov M.V.2

In Paper I we discussed the strange properties of CSL1: a peculiar object discovered in the OACDF which spectroscopic investigations proveed to be the double undistorted image of an elliptical galaxy. Always in Paper I we showed that CSL1 could be interpreted as the first case of lensing by a cosmic string.

In the present work, starting from consideration that a cosmic string is an elongated
structure which produces non local effects we investigated the statistics of lens candidates around the CSL1 position.

Supersymmetry

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

— Nikolai Lobachevsky


John Ellis:

Extensions of the Standard Model often contain more discriminatory parameters, and this is certainly true of supersymmetry, my personal favourite candidate for new physics beyond the Standard Model. One of the possibilities suggested by supersymmetry is that Higgs bosons might distinguish couple differently to matter

Without consideration of that early universe, the quantum interpretation doesn't make sense unless you include it in something whole?



Lubos said,

There are also many other, indirect ways how can we "go" back in time. This is what evolution, cosmology, and other fields of science are all about.

Symbolically how do you create a inclusive system, but to look at alien and foreign ways in which this logic might force you to consider the interactivity of a theory of everything? Greater quark distance, greater energy, higher gravitational field generation. The field around this distance, and supersymmetrical realization bring us closer to the source of the energy creation, closer to the source of the universe's beginnings

....to consider such eneregies within the sphere of M, at a quantum level, as well at such cosmological scales."

The Bubble Universe / Andre Linde's Self Creating Universe

These are the theories discussed in class. The bubble universe concept involves creation of universes from the quantum foam of a "parent universe." On very small scales, the foam is frothing due to energy fluctuations. These fluctuations may create tiny bubbles and wormholes. If the energy fluctuation is not very large, a tiny bubble universe may form, experience some expansion like an inflating balloon, and then contract and disappear from existence. However, if the energy fluctuation is greater than a particular critical value, a tiny bubble universe forms from the parent universe, experiences long-term expansion, and allows matter and large-scale galactic structures to form.

The "self-creating" in Andre Linde's self-creating universe theory stems from the concept that each bubble or inflationary universe will sprout other bubble universes, which in turn, sprout more bubble universes. The universe we live in has a set of physical constants that seem tailor-made for the evolution of living things.

It is very difficult sometimes to bring another individuals view in line with the vast resources that could point the mind to consider the whole thing?



If you did not have a encompassing philosophy, and I know this word is dirty to some, but without pointing to a basis for which the universe sprang, then such topological features would never make sense.

So you direct the thinking to what the early universe looked like(?), and it's potential for expression. A lot of things are going on that are not considered geometrically/topologically unfolding, which hide within the basis of expression. So you have to use analogies to nudge the mind into possible structural considerations, with evidence of graviton production?

Notes on Hyperspace Saul-Paul Sirag

The rule is that for n hidden dimensions the gravitational force falls off with the inverse (n + 2 ) power of the distance R. This implies that as we look at smaller and smaller distances (by banging protons together in particle accelerators) the force of gravity should look stronger and stronger. How much stronger depends on the number of hidden dimensions (and how big they are). There may be enough hidden dimensions to unify the all the forces (including gravity) at an energy level of around 1 TeV (1012 eV), corresponding to around 10-19 meters. This would be a solution to the hierarchy problem of the vast difference in energy scale between the three standard gauge forces and gravity. This is already partly solved by supersymmetry (as mentioned previously); but this new idea would be a more definitive solution--if it were the right solution!

Testing Theoretical Ideas of Extra Dimensions

"Yet I exist in the hope that these memoirs, in some manner, I know not how, may find their way to the minds of humanity in Some Dimensionality, and may stir up a race of rebels who shall refuse to be confined to limited Dimensionality." from Flatland, by E. A. Abbott

Leaking Gravity May Explain Cosmic Puzzle

Gravity leakage should create minor deviations in the motion of planets and moons. Astronauts on the Apollo 11 mission installed mirrors on the lunar surface. By shooting lasers at the mirrors, a reflected beam can be monitored from Earth to measure tiny orbital fluctuations. Dvali said deviations in the Moon's path around Earth might reveal whether gravity is really leaking away.

You know for me, it's not enough just to swipe away ideas that have been expounded in a theoretical approach. Are we doing a disservice to the scientific process not to explore these potentials along the roads of theoretical ideas born and discharged to discussion?

Moonscience - Quakes, Shakes and Laser Beams

The second chief experiment in the Apollo 11 science package was the Laser Ranging Retro-Reflector, or LRRR. Roughly one foot square, the LRRR was a configuration of specialized mirrors that possessed the property of always reflecting light in the same direction as its source. The reflector was set up about 16 feet (5 meters) from the solar-powered seismic recorder. Resting on the lunar surface it resembled an oversize hotplate with a shiny top. It would be used to reflect laser beams sent from Earth in order to make very precise measurements of Earth-Moon distances. Although the moon is on average about 238,000 miles (385,000 kilometers) away from Earth, using this method, scientists can measure the Earth-moon distance to an accuracy of about 1 1/4 inches (3 centimeters).

I have listen to the Skeptic approach to resistance of something that has not been proven to exist, yet I had found things existing within our culture that said, yes it has not been proven, yet there is a track record of what GR has accomplished.

So should we let the resistance of fear insight distrust of the media, and have good science minds disrupt by instigating false reports like the one did by Alan Sokal in regards to quantum gravity? Nice way to treat those who move up to face the challenge of a theoretcial world that expects the same validation as any process?

I don't argue this, but I wonder then if we are given gravitational wave production such a vast monetary reward for such developements from what Einstein produced, then what justification was awarded such experimental processes, to say ,that the ideas of some I have been expounded in terms of those extra dimensions.

I thank Lubos Motl for speaking to the deconstruction process and what is being implied in particle reductionsism. What it has lead us too. He is advocating good technical structure for comprehension of thos esame dimensions and points out the theoretical spaces that this mathematics is involved in.



Q<->Q measure a reveals a much more dynamical world theoretcially that needs to be entertained.

Eric Adelberger and Blayne Heckel of the University of Washington in Seattle are no strangers to difficult gravity experiments. In the 1980s, they led one of a number of groups that investigated the existence of a postulated fifth force, which would show up as a gravitational anomaly over distances of up to 100 metres. Their findings helped to kill the idea.

Would you lesson the impact of Gaussian coordinates to any substantial view, because it makes use of those same theoretical spaces?

Dimopoulos has been strongly driven in his research by a desire to understand what lies beyond the standard model. His contributions have included work on grand unified theories of baryogenesis, which would provide an explanation of the origin of matter. Jointly with Stanford colleague Nima Arkani-Hamed and Gia Dvali of ICTP, Trieste, Italy, he has proposed an audacious solution to the problem of explaining the weakness of the gravitational force. The proposal invokes new large dimensions accessible to the graviton

The Eöt-Wash Group: Laboratory Tests of Gravitational Physics

Stretching the Brain

Pettit shakes a remarkably sturdy film of water onboard the ISS. See the full-length movie: Reel 1, Reel 2.

"Observations of nature, no matter how seemingly arcane, are like peeling off one more layer from the great onion of knowledge, tickling your imagination with what you have found but always revealing yet another tantalizing layer underneath," says Pettit.

"I hope we never get to the core." See:Saturday Morning Science

What strikes me as strange is how we could have percieved the language of branes, with somekind of toy model even though we can't see them. For me as a sideliner, who views the world of these theoreticists, I had to try and make sense of this language they are talking about.

So I looked for some comparisons and geometrodynamics came into view, but I mean this couldn't have even been fathomable if we say it is hidden ,what the heck does this mean? The dimensional relevance had to be spoken and our visulizations moved beyond the euclidean points to a non euclidean world of metrics realization between these quark to quark measures.

So in the spirit of Feynmen, how about we use these new features to help us orientate the views of the world that is hidden and help many understand the world contained in the vacuum, that many could never have comprehended?

Lubos likes Moose horns as a analogy for Feynman path integrals?:)

Here I would look at Dvali's analogies to move the consideration forward place within context of this post.

It is part and parcel of the view I am developing, in relation to the geometrical/topological understanding that comes out of the view of how this universe came to be. I know this would quickly align some persepctives in that geometrical consideration. But having viewed Daniel Kabats response how would we describe non conformal geometries that arrive in the spaces Daniel speaks about?

So any way, here is the new toy model that one should work with, and correspond developing language in relation too GR's developing views along side of the small world we all are trying to capture.

LQG is successful here in the intersecting bubble technology(simpleces and monte carlo models in representing quantum gravity?), in regards to it's nodes, but how would string theory survive. You had to know that underlying this language is some kind of consistency. String theory represented in the graviton, points to the question for the quantum geometry/topology that will explain this unseen world that has been theorized.

Quivering, in quark to quark measures are a interesting way in which to see the world theory spaces and not the points. The configurations space would have to explain the geometry in a way the Gaussian coordinates would help us view a dynamical world?

So string theory is, among many other things, a theory of gravity!

Daniel Kabat


A picture of flux lines in QED (left) and QCD (right).

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

One of the particle states of a closed string has zero mass and two units of spin, the same mass and spin as a graviton, the particle that is supposed to be the carrier of the gravitational force

Brane New World

If some thought is beyond comprehensible to engage string theory and come away with some simple statement about it, imagine if we are taken to the new heights that Brane New World might implicate.

But first, having understood something about the matrix involved I tried to educate myself and look for the thread that would bring feynman to dirac for his toy model production.

P.A.M. Dirac was a gifted mathematical inventor who saw how quantum mechanics rises from classical mechanics, yet transcends it. Dirac did not know of the Bohr atom when he arrived at Cambridge in 1923; yet he quickly began contributing to the mathematical structure demanded by quantum phenomena, discovering the connection between the Poisson bracket and the commutator of Heisenberg”s matrix representation of observables. Then, with careful attention to its classical antecedent, Dirac found the equation governing the evolution of the matrix elements which had eluded Heisenberg in the operator ihdA/dt = [A,H]. He then went on to discover spinors in describing the relativistic electron and antimatter implied by the quantum in relativistic space-time. Dirac conceived the many-time formulation of relativistic quantum mechanics and laid the foundations of the Feynman path integral thereby opening the way to quantum electrodynamics. Newton synthesized the foundations of classical mechanics. In fitting kinship, Dirac, who did the equivalent for quantum mechanics, filled the chair at Cambridge held by Newton.

Well when I moved to the higher dimensions it became extremely difficult to understand that if in Brane New World antics as revealled by Dvali, these concepts are simply discussed, but have far reaching implications.

Dvali uses the analogy of a metallic sheet submerged in water to illustrate the principle. If one hits the sheet with a hammer, shock waves will carry away the energy in all directions. "Most of the energy will travel along the two-dimensional surface. Only at a substantial distance away from the source will the energy loss to water be appreciable," he said. "According to our picture, we are in a very similar situation. We think gravity is 'normal' because we only measure it directly at relatively short distances, but cosmic acceleration indicates leakage.

"

This simple visualization does more to ask, how we could look at what is being held to this brane, to understand that the way that vibration moves across his example, would have some correpsondance somewhwere else for consideration.

It is always easy to visualize the three coordinated universe as a box, and if using loop amplitudes within context of Greg" Egan's example, you are going to meet the faces that these loops reflect. This pointed to something beyond the faces of these coordinates for me, to realize, that beyond the four dimensinal views there was a world that we were missing in consideration. Those missing energy events speak to this, for me.

So the following picture I hope clarifies what I have been saying for sometime from a M Theory perspective.

Unfortunately the image I had on file is no longer connected to it's source so the site gone takes the image with it. This logic was part of the developement I see in the interenet that would reveal the source and not compromize it's auhtor's rights?

So of course I had to go look at how I would see Dvali's statements about the hammer heating the metal sheet.

Missing Energy Events

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

Albert Einstein
(1879- 1955)


Oskar Klein (left) proposed in the 1920s that hidden spatial dimensions might influence observed physics. He poses with physicists George Uhlenbeck (middle) and Samuel Goudsmit in 1926 at the University of Leiden, the Netherlands. AIP Emilio Segrè Visual Archives

It is not easy for me to follow so many minds involved in the deeper intricacies of a world, that abstractually was built, to concieve of other possibilties. If it fell within the mind's capabilties to allow such ventures, then such values become developed in the mind's neurological developement?

High energy particles have extremely small wavelengths and can probe subatomic distances: high energy particle accelerators serve as supermicroscopes:

To see What?

The structure of matter

(atoms/nuclei/nucleons/quarks)


Did it see tidbits of nature, and ways, in which to explain other views of the microscopic world? What "eye" was held to the microscope(particle reductionistic further refined) and then, with such endearing qualties spoken to us, takes us on a journey well concieved and observed?



For me then to view this compact world, and reveal the dimensional attributes of something that may seem so foreign and alien in it's guise, I realize that for the mind to peer into the deeper workings of the microscopic world, we had to understand the images the we could produce, as we learn to build mathematical structures for contemplation

Dvali uses the analogy of a metallic sheet submerged in water to illustrate the principle. If one hits the sheet with a hammer, shock waves will carry away the energy in all directions. "Most of the energy will travel along the two-dimensional surface. Only at a substantial distance away from the source will the energy loss to water be appreciable," he said. "According to our picture, we are in a very similar situation. We think gravity is 'normal' because we only measure it directly at relatively short distances, but cosmic acceleration indicates leakage.

"

To further expand on this idea of Dvali's I wanted to draw attention to the principals of this leakage. Bear with me as I try to find the literature that I have accumlated, for what is spoken now has triggered my memory by selection of these words.

So the process now is to remember where these views were previously spoken about and bring them back here for a wider comprehension of the leakage and the dimensional significance implied by Dvali, of where this extra energy is going?

Hopefully we wil see other minds involved in string theory speaking on this matter, to seal what they are doing and descibing where they think this extra energy is going?

Given the dearth of knowledge about gravity in the subcentimeter range, the group is looking for any kind of deviation from expectations, not just extradimensional effects, he says. Nonetheless, the excitement about extra dimensions helps spur the group on, Price says.

If the strength of gravity takes a sharp turn upward at around 1 TeV, as the Stanford-Trieste scenario implies, an opportunity opens for testing this theory also in accelerators. Collisions at such energies could produce gravitons in large numbers, and some of these particles would immediately vanish into the extra dimensions, carrying energy with them. Experimenters would look for an unusual pattern of so-called missing energy events.

This and more subtle effects of extra dimensions could show up at existing accelerators, such as LEP and the Tevatron at Fermilab, only if the dimensions have scales nearly as big as a millimeter. The powerful LHC will greatly improve the chances for detecting missing energy events and other prominent extradimension effects.

The bold highlight of the article preceding, points to the realization and values of what the gravitons appear to be able to do. How they can take this energy with them into those extra dimensions. This is a very important insight, that must be considered, and not just shelved because the mathematics seem disjoined from reality.

The basis of the capabilties of the dimenisonal significance in regards to these topological manueverings, had to have some basis to move from, and it is this essence, that string theory acknowledges? The energy of these gravitations in a world quite capable of being grviaational discribed, can now have a foundation in which we may describe this dynamcial issues at the quantum level?

We have moved the GR considerations of D>=4 to a much more dynamical recogntion of the probabilties inherent in energy determinations and also grvaitonic condensation values withinthe blackhole.
