Cyclical model offers a new perspective on the universe from "summary" of Endless Universe by Paul J. Steinhardt,Neil Turok
The cyclical model posits that our universe undergoes an endless cycle of expansion and contraction, with periods of growth followed by periods of collapse. This model challenges the traditional view of the universe as a linear progression from a singular Big Bang to an indefinite expansion. Instead, it offers a new perspective that suggests the universe has no beginning or end, but rather exists in a perpetual state of renewal. By incorporating concepts from both general relativity and quantum mechanics, the cyclical model provides a comprehensive framework for understanding the origins and evolution of the universe. It suggests that the universe may have existed long before the Big Bang, and will...
