It's easy to forget that long standing scientific theories are in fact, theories and therefore are subject to revision and change as new information comes to light or we develop new ways to understand our Universe. The current accepted theory on the creation of our Universe is, of course, "The Big Bang Theory". But cutting edge new work is threatening to replace it with something else, "The Big Bounce Theory." So did the universe begin with a Big Bang or a Big Bounce? Did the Universe even "begin" at all? Join Richard and Peter and their guest, theoretical physicist Anna Ijjas from the Max Planck Institute of Gravitational Physics. They talk about her groundbreaking work that suggests our seemingly finite Universe is actually infinite, no beginning and no end. Prepare to have your mind blown as we tackle "What If the Universe is bouncing?" on "What If Discussed."
