Stars Ask Neil Their Deep Questions... Again!

How certain are we about aliens? Neil deGrasse Tyson and cohosts Chuck Nice and Gary O’Reilly answer science questions from celebrities like Kevin Hart, Jack White, Nikki Glaser, and more! Comedian Kevin Hart asks if space can take the wrinkles out of a pair of wrinkly pants. We discuss ways you would iron clothes while still wearing them in zero gravity and whether Kevin would have a space valet. Musician Tommy James asks a question about his morning coffee and time travel. Comedian Nikki Glaser asks about aliens and how sure we are that they exist. We break down the composition of the universe, how common the ingredients for life are, and silicon-based life. How much of space has SETI even looked at? Plus, we explore if love is real. Do other species experience love? Could aliens experience love? Musician Jack White asks about how rare gold is in the universe and on the planet we live on. Learn about how gravity sorts elements and how much gold can be found in asteroids. Cam Johnson, of the Brooklyn Nets, asks if we can feel the different speeds of Earth’s rotation at different longitudes. Is there one part of the Earth that isn’t rotating?
