Urgh, Microsoft Sam.

Oh c’mon, it’s clearly a Pollock. I can see where he dripped the paint!

The U parameter’s probably safe.

Awesome, best thing along those lines since Bush found an error in some calculations done at Fermilab. I suppose Bush is more traditional particle theorist, well steeped in the intricacies of renormalization and summing integrals while Sarah seems a bit more in tune with theory well beyond the standard model.

Sean,

No, I haven’t publish anything on that. I did make some simple math – but it’s trivial and easily subject to criticism, cause introductions of quantum entropy and quantum time are too easy. The physics are now deep into it – building of a new dimension or quantification instead of continuity can relatively easy break most of visible discrepancies and paradoxes. So, I never dig the subject seriously. Any subject where one can argue upon or against without experimental or strong theoretical prove is simple, aren’t you agree?.
If you incline to do some serious job on that and if you are interested in any of my thoughts, you always welcome to use what you think is feasible, no obligations.

It is worth clicking on the IRAS image, because it gives a good indication of the size of the area that is covered.

*lol* Not bad. Sounds like a scrambled recording from questions in a parallel session on physics beyond the standard model.

It should be noted that of the three wavelengths that went into this image, two came from Planck (540um and 350um) and the third from IRAS (100um), a satellite which mapped the sky in the early 1980s. The IRAS contribution alone can be seen in this image.

per,
Inflation should lead to a flat universe. At the time the theory of inflation was introduced (1980 or so) we had no idea whether this condition of flatness would hold, but our latest data suggests that it does. Flatness is a “just so” condition, requiring very tight bounds on the parameters, and so seems (to me) unlikely to have occurred by coincidence.
