Cosmic Queries – Wormhole Universe, Black Holes, & Simulations with Neil deGrasse Tyson

Does an evaporated black hole leave a trace? Neil deGrasse Tyson and comedian co-host Chuck Nice answer questions about the fabric of spacetime, black holes, cosmic evolution and more. How do black holes die? We discuss what would happen to a universe contained within a black hole when it evaporates and what a black hole does in its final moments. Would life on a large planet move slower than life on a small planet? What would organisms on a planet with stronger gravity look like? How would the universe be different if it started with high initial entropy? What is entropy? Is time an emergent property of quantum entanglement? We talk about life in other dimensions and whether black holes could be wormholes. Learn about cosmic evolution and how we categorize stars. We explore simulation theory and whether simulations are self propagating. How can you tell direction in space? Could mass and gravity have something to do with quantum entanglement? Finally, we help define string theory and also explore the nature of gravity itself.
