Cyclic universe offers solutions to cosmological puzzles from "summary" of Endless Universe by Paul J. Steinhardt,Neil Turok
The idea of a cyclic universe is an intriguing one that has gained attention in the field of cosmology. Instead of a universe that has a definite beginning and end, the cyclic universe posits a never-ending cycle of birth, evolution, and death. This concept offers potential solutions to some of the most perplexing puzzles in cosmology. One of the main puzzles that a cyclic universe addresses is the problem of the Big Bang singularity. In a traditional cosmological model, the universe began from a singular point of infinite density and temperature. This singularity presents a challenge to our understanding of the laws of physics, as they break down under such extreme conditions. However, in a cyclic universe, there is no need for a singular beginning. Instead, the universe goes through cycles of expansion and contraction, avoiding the problematic singularity. Another cosmological puzzle th...
