Turtles and Elephants

There is this notion that to work with different species and incorporate them, it some how makes it more natural an explanation?(guilty):) I guess I am guilty of same and more, by using geometrical progressiveness in place of the propensity for nature to be revealing itself in varying degrees. It was always there for inspection?

So anyway this clip I took from a previous post on, "Who said it?" charts the example I give currently in line with Bee's Backreaction: Turtles all the way up I did not go beyond the introduction, and assume it was not Davies talk. I was cut off at 14 meg while the whole talk is much longer. I'll have to try again tonight(08 sep 2008).

I still have yet to download Davies talk, given the constraints the work schedule limits with regard to the "intranet."

But just reading briefly Dr. Who's position and Markk suggestion that Dr. Who is confusing model with reality.

Bold and italicized were added by me.

The Coleman-Mandula theorem, named after Sidney Coleman and Jeffrey Mandula, is a no-go theorem in theoretical physics. It states that the only conserved quantities in a "realistic" theory with a mass gap, apart from the generators of the Poincaré group, must be Lorentz scalars.

In other words, every quantum field theory satisfying certain technical assumptions about its S-matrix that has non-trivial interactions can only have a symmetry Lie algebra which is always a direct product of the Poincare group and an internal group if there is a mass gap: no mixing between these two is possible. As the authors say in their introduction, "We prove a new theorem on the impossibility of combining space-time and internal symmetries in any but a trivial way."[1]


First off let me give you an example and you tell me how the idea of any bulk perspective given to graviton understanding will not have it's examples in terms of Lagrangian in space? Serve to help one graduate in terms of gravities when looking at the universe?

Are there no other mechanism that details the Coleman Mandula action other then a multiversity idea in terms of the false vacuum to the true?

I encourage such topological understanding given to a larger format when looking at WMAP of the global perspective. Incidences within the universe give way to a larger depiction of the anomalies generated in perceived examples of monopoles generated in Sean Carroll's group think.

That such concentrations in graviton densities would have an impact on our perceptions in terms of Lagrangian.

If one were to say that any manifold generated at the perception of microscopic views were indicative of a larger topological suggestion in the WMAP, would this then not account for an impression of 10 sup-500-/sup(only written this way because comment section will not allow "sup" html discription)?

Gravities had to be inclusive at all stages and manifold expressions part of this cosmological view?

Valuing Negativity by Mark Trodden

The basic point is that if one assumes that the generators of the internal symmetry group are commuting operators (and that their commutation relations define the group - i.e. that they comprise a Lie algebra), then the only possible total symmetry is a direct product of the space-time symmetries (the PoincarĂƒ© group) and the internal symmetry group. This is what they meant by trivial in the abstract.

If this had been the end of the story, then bosons and fermions (and therefore force carriers and matter) would be destined to forever remain distinct. But here comes the loophole. The 1975 Haag-Lopuszanski-Sohnius theorem (after Rudolf Haag, Jan Lopuszanski, and Martin Sohnius) pointed out that if one relaxes one of the assumptions, and allows anticommuting operators as generators of the symmetry group, then there is a possible non-trivial unification of internal and space-time symmetries. Such a symmetry is called supersymmetry and, as you know, constitutes a large part of current research into particle physics.

No-go theorems are fun in physics because they formalize where the important barriers lie and provide guidance about the directions of future attacks on the problem in question. Negative results in general, although not quite as glamorous or exciting, are still great stuff. We should celebrate them. Plus, we don’t want to be like the medical community do we?


Identify the early universe in the QGP perspective needed some way in which to limit reductionism points of view and by incorporating relativity at that level, such an expression then are imparted to a more global manifold detail based on a larger progressive geometry perspective of the universe.

Universe speeding up? From the inside/out this details such a connection in my view.

Best,


This was done to verify the statements made in two comments there and to show a comment made at cosmic variance's "Lopsided Universe" were related exactly to the points I am currently making in regard to a point of view shared by Dr. Who and a consequential statement by Markk in terms of the multiverse and bubble nucleations.

Sean Carroll:But if you peer closely, you will see that the bottom one is the lopsided one — the overall contrast (representing temperature fluctuations) is a bit higher on the left than on the right, while in the untilted image at the top they are (statistically) equal. (The lower image exaggerates the claimed effect in the real universe by a factor of two, just to make it easier to see by eye.)
See The Lopsided Universe-. Basically the comments I have made in this post by Sean have remained intact although toward the end I think it was thought I might have gone to far?

Dennis William Sciama

Dennis William Siahou Sciama FRS (November 18, 1926–December 18, 1999) was a British physicist who, through his own work and that of his students, played a major role in developing British physics after the Second World War.

Sciama also strongly influenced Roger Penrose, who dedicated his The Road to Reality to Sciama's memory. The 1960s group he led in Cambridge (which included Ellis, Hawking, Rees, and Carter), has proved of lasting influence.

Sciama was elected a Fellow of the Royal Society in 1982. He was also an honorary member of the American Academy of Arts and Sciences, the American Philosophical Society and the Academia Lincei of Rome. He served as president of the International Society of General Relativity and Gravitation, 1980-84.

In 1959 he married Lidia Dina, a social anthropologist, who survived him, along with their two daughters.

It was important that I understood the context of the entry by Phil Warnell.

Phil:
However, if the second is taken as truth and all is remembering, then what can the force of gravity do to a memory that is not in any, yet of all? So if all were to collapse would the memory not persist, since it is not of what vanished. Strangely, Hawking proved it so and yet he still denies his mentor who advised not only that it would be so, yet why

Strings: The First Three Seconds

I didn't want to invoke God here, but in any "flash" is there not some pattern that mathematically needed to describe the way everything began? A word, or sound?

An equation means nothing to me unless it expresses a thought of God.Srinivasa Ramanujan



Before the Beginning
Interview with Sir Martin Rees, Part 2


Helen Matsos (HM):
Last year the big "science event" was measuring the cosmic microwave background and dating the big bang to 13.8 billion years ago, within an 8 to 10 percent margin of error. Can you give us some idea of the boundaries of the big bang -- what was it like in the first seconds, and how far will the universe expand in the future?


So indeed the universe become entrophically considered, as the evidence starts to make itself known in all it's forms, yet there is a space. Now by itself, such expression of the universe would have one event, but imagine down on earth our moments, can cause such repercussions ahead in time?

AM:
You played yourself--twice--in the movie, "Frequency". The movie is about a father communicating from 1969 with his son in the present on a ham radio, due to an unusual atmospheric aurora that bounces radio signals across time, not just space. You played Brian Greene being interviewed by Dick Cavett as both a younger and older man. Any reflections on either the interesting premise of the movie, or the adventures of being on the big screen?


So how we categorize such encounters with the child in our hopes of encouraging it's future, or our very presence and example lead. As a sign post, of what any society could become in the eye of good moral men and women? So one can move quietly no doubt and remain unseen, while the work can be a gentle reminder, of how we can affect "each" in time. Words like "etc" that could take on greater meaning, to have the hand slight a deletion. Remember how sensitive we can be to music? In Plato's academy I had made this point clear. I make clear what dissonance can do:)It can definitiely ruffle the field. Straight up and straight forward, a comment should do for those that would like to learn.

Brian Greene
Time is far more subtle than our everyday experience would lead us to believe. In many ways, time may simply be a psychological construct for organizing the world. It is a device we scientists have found useful, but it may in fact be a dim approximation of something far more complex."


WEll here is a better view on the relation to the The Powers of Ten

I talked briefly on the "chance encounter" of a child with a scientist, and the alluring role of powers of ten takes on. As if, it can "reverberate" in the probabilities of a future time.

Who is responsible for this creative surge?:)Creative endeavors, are always fueled by another?

IN such a cultural context, how is it that we could not see underlying reality is a musical inclination taken form in what any future could become. So, by the very value of the resonance contained, a feature of any moment?

Calming the Fears by Making Aware

If we discover the Planck scale near the TeV scale, this will represent the most profound discovery in physics in a century, and black hole production will be the most spectacular evidence of that new discovery

It is important to understand where this research has lead some of us to looking. We mentioned Steve Giddings earlier and Lubos has provide some of this information that helps to further enlighten. Because there are fundamental processes unfolding in high energy considrations it is well that we are aware of the encounters that can come forward in the production of these particles?

Parallel worlds

What do you think of Sir Martin Rees' concerns about the risk of creating black holes on Earth in his book, Our Final Hour?
Michio Kaku:

I haven't read his book, but perhaps Sir Martin Rees is referring to many press reports that claim that the Earth may be swallowed up by a black hole created by our machines. This started with a letter to the editor in Scientific American asking whether the RHIC accelerator in Brookhaven, Long Island, will create a black hole which will swallow up the earth. This was then picked up by the Sunday London Times who then splashed it on the international wire services, and all of a sudden, we physicists were deluged with hundreds of emails and telegrams asking whether or not we are going to destroy the world when we create a black hole in Long Island.


So the very idea that creation of blackholes, might have seemed somewhat strange then what is postulated in terms of being possible here, would help to further enlighten? We have been directed already to what is available around us in our new perspective views. So we have advanced here:)We do not overwhelm cosmological idealizations, with "false ideological statements" about it's uselessness.

The Quantum Universe

The LHC and a Linear Collider will address many questions about extra dimensions: How many extra dimensions are there? What are their shapes and sizes? How are they hidden? What are the new particles associated with extra dimensions? Through the production of new particles that move in the extra space, the LHC will have direct sensitivity to extra dimensions 10 billion times smaller than the size of an atom. A Linear Collider would determine the number, size and shape of extra dimensions through their small effects on particle masses and interactions. There is also a chance that, due to the existence of extra dimensions, microscopic black holes may be detected at the LHC or in the highest energy cosmic rays.


We can now see, where such applications, have further been developed. It was somebody else's being short sighted, that one realizes that there is a particle concern to how we percieve the nature of our universe:)



Understanding Matter, Energy, Space and Time:The Case for the e+ e- Linear Collider
Other ideas to solve the hierarchy problem postulate extra spatial dimensions beyond the three that we know, or new particles at the several TeV scale. If such ideas are correct, we again expect observable consequences at the LHC and the LC and a synergy will exist between them. For example, the LC and LHC combined can deduce both the size and number of extra dimensions. The new states expected from extra dimensions could perhaps be sensed directly at the LHC, but the precision measurements at the LC can measure their effects even for particles well above the range of the direct measurements.


So ever closer now one must pay attention to what does "not make sense" and we find that tidbits being left around actually if perceptive enough, will help you to explore other things. See, if I am told once and you read, the depth of perception will never make sense if you don't follow those leads and Lubos gave us one to consider:)

Peter SteinbergThe creepy part of these kind of discussions is that one doesn't say that RHIC collisions "create" black holes, but that nucleus-nucleus collisions, and even proton-proton collisions, are in some sense black holes, albeit black holes in some sort of "dual" space which makes the theory easier.




And if you are even more thick skinned, what focused can be developed from that to here. So if you do not understand the question, it is obvious you have not followed what was put before you for consideration. Hence Crackpotism or senseless?

It is a easy hand, under chin contemplating, playing games like rock, paper, or scissors ( that one can wave off) as to what is not understood as being senseless.

It is a better hand that can point up with the finger(heaven) or a open hand(ground) to say, look around you?:)We would like to develope these concepts further, under the Arche. We may be old personalities, but we still like to discuss the nature of the universe.:)
