Rings in Sky Leave Alternate Visions of Universes

From NYTimes, Nov 30, 2010:

...Roger Penrose, the eminent British mathematician, is arguing that there is physical evidence that may predate the Big Bang. In a recent paper, he and his co-author, the physicist V. G. Gurzadyan, describe a pattern of concentric circles detected against the universal backdrop of cosmic microwave radiation generated by the Big Bang. These circles, they say, may be gravitational waves generated by collisions of superbig black holes before the Big Bang.

The two scientists go even further, claiming that the evidence also suggests that our universe may “be but one aeon in a (perhaps unending) succession of such aeons.” What we think of as our “universe” may simply be one link in a chain of universes, each beginning with a big bang and ending in a way that sends detectable gravitational waves into the next universe.
