What is a wormhole? On this StarTalk explainer, Neil deGrasse Tyson and comic co-host Chuck Nice investigate the science of wormholes and how they work. You’ll learn how gravity is the curvature of spacetime. We talk about the “speed limit” of the universe and how to break it using a wormhole. But, how do you keep a wormhole open? Is it prone to collapse? All that, plus, Neil and Chuck explore classic time travel movies like Bill & Ted’s Excellent Adventure, Back to the Future, Time Bandits, Contact, and more!
