| Abstract;A model of the "cyclic universe" is constructed based on a minimal set of the properties of the string theory. The string theory predicts that the size of the universe is bounded from below, and that the energy and temperature are bounded from above. As time goes back to the era of the birth of the universe, the size of the big bang universe becomes of the string scale. As time goes further back, it reaches the era of the big crunch. There arises the cyclic universe scenario in which the big bans and big crunchs repeat. In the process of the repetition, the universe acquires entropy and attains the huge entropy at the present day. |
