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 continue to exist long after the current phase of expansion comes to an end. One of the key implications of the cyclical model is the idea that the universe goes through an infinite series of cycles, each one giving rise to new physical laws and constants. This challenges the notion of a fixed and unchanging universe, and opens up new possibilities for understanding the nature of reality. The cyclical model also offers a fresh perspective on the concept of time, suggesting that time itself may be cyclical in nature. This challenges our conventional understanding of time as a linear progression from past to present to future, and raises intriguing questions about the fundamental nature of reality.- The cyclical model presents a radical departure from traditional cosmological theories, offering a new way of thinking about the universe and our place within it. By exploring the endless cycles of expansion and contraction, this model invites us to reconsider our assumptions about the nature of existence and the underlying principles that govern the cosmos.
