Description: Could lightsabers work in real life? On this explainer, Neil deGrasse Tyson and comic co-host Chuck Nice sit down with physicist Brian Cox to break down lightsabers, nerd fights, and the eternality of matter itself. Can light bounce off other light? Learn about gamma-gamma scattering and what it means for light to interact with itself. Brian shares a comedy sketch involving Stephan Hawking and his new cosmology show Horizons. Are space and time fundamental or do they come from something deeper? How many civilizations are in a galaxy? What does it mean to live a finite life within an infinite universe? What happens to the stuff that falls into a black hole when it dies? Do black holes destroy information? All that, and we discuss Brian’s upcoming projects!
