Stefan Alexander: infinity is undefined because one divided by zero is infinity. "I've been waiting my whole life and all you have to do is define it," he says. Neil Lagrass Tyson welcomes back his old friend Stefan Alexander for this week's StarTalk, Cosmic Queries.
What is infinity? Neil deGrasse Tyson and comedian Negin Farsad explore whether we are in a finite universe, the issues with infinity, string theory, and more with theoretical physicist Stephon Alexander.
