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! Have we failed to find alien civilizations because they are beyond our cosmic horizon? We explore the Fermi Paradox and go through the options of where aliens could be. Would Neil rather see the dinosaurs or aliens? What’s Neil’s favorite astronomical discovery of all time? Are we losing access to the universe as it expands? We discuss quantum mechanics and whether quantum entangled particles are connected by wormholes. If you fall into a black hole, will you fall past the event horizon at all? What do two mirrors facing each other reflect? We break down the shape of the universe and whether it has an edge. How does scale impact multiverse and quantum theory? Could quantum things happen as we move up in scale? Could you walk on the rings of Saturn? Learn what it would be like to land on Saturn. All that, plus, if you stuck your hand in a black hole would it suck you in entirely or just take your hand?
