WebNov 19, 2002 · If you have a universe, which is cyclic, it is eternal, so you don't have to explain the beginning. During the attempts to try to bring cyclic ideas into modern cosmology, it was discovered in the '20s and '30s that there are various technical problems.

• Conformal cyclic cosmology—a general relativity based theory by Roger Penrose in which the universe expands until all the matter decays and is turned to light—so there is nothing in the universe that has any time or distance scale associated with it. This permits it to become identical with the Big Bang, so starting the next cycle. • Loop quantum cosmology which predicts a "quantum bridge" between contracting and expanding cosmological branches.
