Events before the Big Bang?

Source: arXiv

Roger Penrose, a well known cosmologist, posted an article on the arXiv website were he as co-author of V.G.Gurzadyan says that analysis of this cosmic microwave background showed echoes of previous Big Bang-like events. These events seem to appear as "rings" around galaxy clusters in which the variation in the background is unusually low.

The ideas within it support a theory developed by Professor Penrose - knighted in 1994 for his services to science - that upends the widely-held "inflationary theory". That theory holds that, at a certain moment, the Universe was shaped by an unthinkably large and fast expansion from a single point.

Much of high-energy physics research aims to try to elucidate how the laws of nature evolved during the fleeting first instants of the Universe's being.

The article claims that this aeon is just one of a succession of such things, where the remote future of the previous aeons somehow becomes the Big Bang of our aeon. This "conformal cyclic cosmology" (CCC) that Professor Penrose advocates allows that the laws of nature may evolve with time, but precludes the need to institute a theoretical beginning to the Universe a theory that has been also defended by other cosmologists in several different perspectives.
