Hour Two: Cyclic Universe / Supersymmetry

How does the universe work? What rules make what we know fit together? In this hour of Science Friday, Ira talks with physicist and author Gordon Kane about one theory -- supersymmetry. We'll find out what it is, what it predicts, and how it might be proven.

Plus - what if the Big Bang wasn't the only Bang? An alternate theory of the universe's history says the universe may move in cycles, from bang to crunch to yet another bang. We'll find out more.
