Roger Penrose: Infinite Cycles of the Universe Punctuated by Big Bang Singularities

Professor Roger Penrose's talk outlines Conformal Cyclic Cosmology, a model where the universe's remote, photon-dominated future mathematically scales into the hot Big Bang of a subsequent aeon. This framework proposes that information, specifically gravitational waves from black hole mergers, can survive the transition between cycles to potentially explain the Fermi Paradox as a result of signals from previous universes. While the theory posits that the end of one cosmic epoch becomes the physical beginning of the next through conformal geometry, it remains a speculative hypothesis lacking current detection methods.
