We've all seen plenty of space movies and TV shows to know a little bit about it. Once you're up there in zero gravity everything is different. You have to eat differently, you can float around doing flips, you keep everything strapped down so it doesn't fly away.

There's one question that none of those shows has truly explained to us though. What would happen if a couple astronauts started feeling some romance in the air one late night on the International Space Station? What would it be like to have sex in space?

Well, thank you science for coming through with an answer! By science, we mean astrophysicist Neil deGrasse Tyson and by an answer we mean...well just watch the video and he will explain it.
