Neil deGrasse Tyson Says Sex in Space Would Involve a Lot of Belts

Newton’s Second Law isn’t your friend when you’re doing the free-floating tango

What would sex in space be like? It's a question that's not only on the minds of porn stars

looking to join the 250-mile high club

and bored freshmen in their Astronomy 100 classes, but fans of Neil deGrasse Tyson's Star Talk.

Seeing as he didn't mumble his way out of this video, he's probably fielded odder questions.

To be up and front about it: Newton's Second Law isn't your friend when you're doing the horizontal, or rather, free-floating tango. The Second Law, which involves accelerating masses, isn't much of a problem on Earth because there's always an equal force—gravity and your bed—keeping you from moving anywhere you don't want to.

But in space, where everyone and everything is free-floating, pushing into your partner would cause them to accelerate in that direction until they hit a wall. Obviously, this isn't conducive to sex in any way.

Tyson's solution for this? Belts. Lots of belts. Kinky connotations aside, while belts wouldn't make zero-g sex any less complicated, they would at least keep your partner, and you, from crashing into walls whenever either of you smacks into the other.
