Which is the better fictional spacecraft: the Millennium Falcon from "Star Wars" or the Starship Enterprise from "Star Trek"?
In a new video from National Geographic, a fan asks celebrated astrophysicist Neil deGrasse Tyson which one he would choose -- and he answers with a bit of sass.
"There's no question," he said. "In a battle, the Enterprise would wipe its ass with the Millennium Falcon."
Just check out Tyson's response in the video to hear his carefully thought-out reasoning.
