Popular astrophysicist Neil deGrasse Tyson joined Late Show host Stephen Colbert on Friday night to take part in a new weekly Colbert segment: "Friday Night Fights."
Each week, Colbert plans to invite a guest to take sides on important debates -- such as who would win in a fight between Adolph Hitler and Darth Vader -- before allowing viewers and fans to vote on Twitter.
Friday night's main topic: "Which is more inescapable: the super massive black hole at the center of our galaxy, or the obligation to be with your family at the holidays.”
After listing the strengths of each contender, Colbert invited deGrasse Tyson to weigh in.
"As an astrophysicist I gotta go with the black hole," Tyson stated.
"Oh, really," Colbert replied, " I've got one thing to say to you, my friend, 'Nana is 97 and she'd like to see you one more time before she dies.' Go ahead. What's your next shot? "
Admitting that was indeed a force of nature, deGrasse Tyson said when he was in college he failed to come home for Thanksgiving one year, "And they didn't let me forget it for 10 years."
He then went on to make his pitch for black holes.
