Talk Title:  “What happened 13.8 billion years ago?”


According to the prevailing view, the universe sprang into existence 13.8 billion years ago in a sudden violent event known as the big bang; and this was soon followed by a brief period of accelerated expansion, known as inflation, which set the large-scale properties of the universe.  In this talk, we will explain the reasons why this idea fails and present a simple alternative – replace the big bang with a bounce and eliminate the need for inflation.
