Neil deGrasse Tyson is choosing sides in entertainment's space race between "Star Trek" and "Star Wars"– on scientific grounds, of course.
"I'm 'Star Wars' fluent, but I'm a bigger 'Trek' fan," Tyson, 56, told Rolling Stone as excitement around the next "Star Wars" chapter, "The Force Awakens," climbs.
He continued, "There's a promise of actual science going on in 'Star Trek'— but not so much in 'Star Wars.' I won't be first in line to see the new 'Star Wars.' I can wait until it's on video! But I applaud the fact that it has people thinking about space."
Tyson, who hosts National Geographic Channel's "Star Talk," also explained which TV shows he preferred during his youth. This time, "Star Trek" doesn't fare as well.
"I was a mild 'Star Trek' fan, but my favorite show then and now is 'The Twilight Zone,' especially the episode called 'The Invaders,'" he said.
