Neil deGrasse Tyson (@neiltyson), astrophysicist, science communicator and author of the fantastic new book Astrophysics for People in a Hurry, joins Matt and Andy for a Definitely Science episode, discussing, well, the entire universe: Its origins, the forces that govern it, general relativity, the multiverse, dark matter, dark energy, the fact that the universe is under no obligation to make sense to you, and the questions that Neil would ask a physicist in the year 2317. This episode is brought to you by Parachute; visit parachutehome.com/science for free shipping and returns and a no-risk 60-night trial. Also, check out Andy and Matt's new video for Wired.
