Did a 'sleeper' field awake to expand the universe?
    •    11 June 2010 by Anil Ananthaswamy

To overcome this daunting discrepancy, physicists have resorted to other explanations for the recent cosmic acceleration. One explanation is the idea that space-time is suffused with a field called quintessence. This field is scalar, meaning that at any given point in space-time it has a value, but no direction. Einstein's equations show that in the presence of a scalar field that changes very slowly, space-time will expand at an ever-increasing rate...

Answer: VALIS ;)

Good post, Jack. I think we all want the answer to Hawking's question. I am not personally worried about it because I know the answer for me and I am very content with it.

VALIS is our future event horizon hologram screen that computes us as images back from the future in my crazy theory. Is it crazy enough to be true or just crazy? This nutty notion started with Gerardus 't Hooft and Lenny Susskind. I grabbed their ball and am running with it to score a basket. ;-)

Well it can't be any crazier than "the universe exists, why there is something greater than nothing"- hold off on putting Sarfatti in that strait jacket gentlemen...perhaps the world would do well to listen to him ;)

I applaud you Jack for taking on Gerard, t'Hoofts holographic principle, and soon that ball will become large enough so that perhaps its not too crazy after all.

The surface of the ball is our future event horizon hologram screen and we are always inside it at its exact center according to Einstein's gravity field equations when combined with dark energy data. This has been proved in Tamara Davis's 2004 Ph.D. dissertation on-line in her Fig 1.1 computer simulation.

See the picture here.

It's a metaphoric representation of the hologram universe - we are always at the center of the holographic universe, i.e. observer-dependent future de Sitter cosmological horizon. This turns Copernicus on his head and is a return to the Medieval View in a way. Actually it's more complex than that and we need to invoke Bohr's Principle of Complementarity.

So, i've learned a little of the Holographic Principle, but what do you mean ''we are always inside it at its exact center'' - is it something obvious? :)

Yes, most theorists do not have a good idea in their heads. They are good math technicians who cannot think well physically. They come up with silly Rube Goldberg mechanisms that are more complicated than the actual facts demand. There is a very simple explanation for both the dark energy and the dark matter using only basic quantum theory and Einstein's general relativity that I have been professing since 2002 or so. My theory makes predictions and is Popper falsifiable. So far, so good - all the observations to date are in my favor. Let's see what the LHC gives.

On the exact center - Google "observer-dependent horizons" "de Sitter space". What we measure depends on light signals. Gravity bends light. Dark energy bends light in a peculiar way.

Actually dark energy defocuses light like passing a collimated beam through a concave lens. In contrast, dark matter like, ordinary matter, focuses light like a convex lens. The dark energy accelerating the rate of expansion of  space defocuses light into a future horizon that is literally a spherical shell of "null geodesics" - possible paths of actual light rays we emit here and now. Our future horizon is always a finite distance from us. We keep getting closer to it, but it would take an infinite amount of clock time to reach it at the Omega Point (not in Frank Tipler's sense of the word). Similarly, we keep getting further away from our past particle horizon that is the shell of light expanding away from the Alpha Point of inflation creating our observable piece of the multiverse.
