Robert McNees@Rog Not stupid at all! Ultimately physics is an experimental science, and speculative ideas need to have observable consequences so they can be tested. Physicists spend lots of time trying to work out how to do this for various proposed ideas.
One pretty well accepted idea about this earlier phase is that it involved a period of “Cosmic Inflation.” Inflation predicts statistical patterns for small variations in the cosmic microwave background which we have observed.
