Are black holes places or objects? Neil deGrasse Tyson and cohosts Chuck Nice and Gary O’Reilly answer grab-bag questions about distorting spacetime, Olbers’ Paradox, singularities, the shape of the universe, and more with astrophysicist Charles Liu. Could you create a cloak of black holes to make time cease for you? Learn about configurations of black holes, time dilation, and Einstein’s relativity. Would it take you until the end of time to reach the singularity of a black hole? What would you see if you fell into a black hole? Are we all just prisoners of the present? Plus, Neil divulges how you can hear his voice at a Beyoncé concert. Can you transfer information using quantum entanglement? We break down how subspace gets used in Star Trek, what it means for gravity to distort spacetime, and how gravity can be used to deflect asteroids. Discover Olbers’ Paradox: why isn’t the entire night sky bright with starlight? If Neil and Charles could time travel, where would they go? Could The Big Bang be a white hole? We talk about creating a Dyson swarm, using aerogel to insulate a journey into inner Earth, and the shape of the universe. Is the universe really flat?
