Implications of cyclic universe model on cosmic microwave background from "summary" of Endless Universe by Paul J. Steinhardt,Neil Turok
The cyclic universe model proposed by Steinhardt and Turok has significant implications for our understanding of the cosmic microwave background (CMB). In a cyclic universe, the Big Bang is not a one-time event but rather part of an endless cycle of cosmic evolution. This has profound consequences for the CMB, which is the afterglow of the Big Bang and provides crucial information about the early universe. In a traditional inflationary model, the CMB is thought to be the result of quantum fluctuations during a rapid period of expansion in the early universe. However, in a cyclic universe, the Big Bang is not the beginning of space and time but rather a transition from one phase of the universe to another. This means that the CMB in a cyclic universe is not just a remnant of the Big Bang but also carries information from previous cycles. O...
