Letter: No need for a bounce to get another big bang?

Published 13 August 2025

From Ian Napier, Adelaide, Australia

The big bounce theory has never held any attraction for me. Our universe is expanding as a result of the big bang, and as the fragments of it get further dispersed, the gravitational force acting on them falls. Rather more attractive is a belief that these fragments will all find their way into an infinite space populated by fragments of an infinite number of other universes. Given time, these fragments from many different universes will accumulate to such a degree that they become part of another big bang(26 July, p 10).
