Big Bang Cosmology Intelligent Design Physics

Sabine Hossenfelder asks: Will the Big Bang repeat?

Hossenfelder: I am not sure that CCC actually solves the problem it was supposed to solve. Remember we are trying to explain the past hypothesis. But a scientific explanation shouldn’t be more difficult than the thing you’re trying to explain. And CCC requires some assumptions, about the conformal invariance and the erebons, that at least to me don’t seem any better than the past hypothesis.

And now black holes can be ghosts…

From previous universe: In Penrose and similarly-inclined physicists’ history of space and time (which they call conformal cyclic cosmology, or CCC), universes bubble up, expand and die in sequence, with black holes from each leaving traces in the universes that follow. And in a new paper released Aug. 6 in the preprint journal arXiv—apparent evidence Read More…

How Roger Penrose proposes that the universe can be eternal

For all practical purposes. From the author of Lost in Math: How Beauty Leads Physics Astray, at her blog BackRe(Action) According to Penrose’s conformal cyclic cosmology, the universe goes through an infinite series of “aeons,” each of which starts with a phase resembling a big bang, then forming galactic structures as usual, then cooling down as Read More…
