Piotr Toronuski from Poland asks a question about the shape of the universe. If we know that the universe is ever expanding, does that mean it has an edge? There's no reason to think there isn't more universe beyond our horizon. The multiverse is what you get for free when you bring quantum physics to general relativity in Einstein. You can have infinite universes that don't overlap.
Are entangled particles connected by wormholes? On this episode, Neil deGrasse Tyson and comedian Chuck Nice answer a grab bag of questions about the Fermi Paradox, Dinosaurs v. Aliens, our cosmological horizon, and more!
