Cyclic conformal cosmology
WebApr 11, 2024 · Penrose has made contributions to the mathematical physics of general relativity and cosmology. He has received several prizes and awards, including the 1988 Wolf Prize for physics, which he shared with Stephen Hawking for the Penrose–Hawking singularity theorems. WebIn the present paper we study the evolution of the modes of a scalar field in a cyclic cosmology. In order to keep the discussion clear, we study the features of a scalar field in a toy model, a Friedman-Robertson-Walk…

This cannot have been simply the result of a conventional quantum gravity. Conformal cyclic cosmology proposes a different picture, of a classical evolution from an aeon preceding …
WebOct 18, 2024 · haushofer said: How does the BGV-theorem fit in with Penrose's Conformal Cyclic Cosmology (CCC)? I'm not sure, but I think the "conformal rescaling" that occurs at each boundary in CCC (where the future boundary of one expanding universe gets matched to the past "Big Bang" boundary of the next) breaks the "expanding" condition of the BGV ... WebFeb 7, 2015 · Penrose’s Conformal Cyclic Cosmology ( [ 12 ], hereafter CCC) is a radical new cosmological model which assumes that the universe consists of a sequence of aeons, each of them a solution of the Einstein equations with sources and positive cosmological constant, each expanding from an initial Big Bang singularity to a space-like future null ...
