On last night’s Late Late Show, James Corden gave Andy Samberg the opportunity to ask everyone’s favorite astrophysicist, Neil deGrasse Tyson, anything. Samberg didn’t squander the opportunity. He asked about the three biggest mysteries of the universe: “First, are we alone in the universe? Second, is time travel possible? Third, if you have sex with a robot does it count as cheating?” DeGrasse Tyson has answers to the first and the third.
