Cycles of Time: An Extraordinary New View of the Universe

work by Penrose

Quick Summary

In Cycles of Time: An Extraordinary New View of the Universe, Roger Penrose proposes his theory of conformal cyclic cosmology. This view suggests that the universe undergoes an endless series of cycles, with the Big Bang being a recurring event.1

This contrasts with the prevailing Big Bang model, which describes a singular origin of the universe. Penrose's theory posits that the end of one universe's expansion leads to the beginning of the next, in an eternal cycle.21
