The Big Bang theory has been widely recognized as the best explanation regarding the origin of the universe. The theory has been repeatedly revised over the last few decades, to solve the dilemmas of how galaxies were initially formed, or how the universe is speeding up today. Also, the cause of the Big Bang Theory is yet to be explained. Paul J. Steinhardt and Neil Turok, two world-renowned authors present a new version of the cosmos. They put forth the "Cyclic Universe" theory. According to this theory, the Big Bang theory was not the actual beginning of time but it was a bridge to a past filled with repeating cycles of evolution that had no end. Endless Universe provides detailed explanations and clears all our confusions regarding the Big Bang model.
