Cyclic model may revolutionize our understanding of cosmology from "summary" of Endless Universe by Paul J. Steinhardt,Neil Turok
The idea of a cyclic universe has been around for centuries, but it wasn't until recently that researchers started taking it seriously. This model suggests that the universe goes through an endless cycle of expansion and contraction, with each cycle lasting billions of years. This concept challenges the conventional view of the universe as a one-time event that began with the Big Bang and will end in a heat death. One of the key features of the cyclic model is that it provides a plausible explanation for the existence of dark energy, a mysterious force that is causing the universe to expand at an accelerating rate. In this model, dark energy is a natural consequence of the cyclic nature of the universe, rather than a mysterious component that needs to be added to the equations to make them work. Another intriguing aspect of the cyclic model is tha...
