Each of his arms is bigger than Bill Nye.
That's Tyson as a college wrestler. Back before he became head of the Hayden Planetarium, Tyson was a regular high school student like the rest of us, with dreams of one day pile-driving the universe and other fellows in unitards. So he became the captain of his wrestling team, and he absolutely looked the part:
We'll spare you the "we got us a badass" joke (but we do).
So he must have gone to grad school to study science and meme creation and gave up sports, right? Nope. Tyson still wrestled competitively deep into his Ph.D. progress, even if it meant sacrificing his free time. To show you the level of commitment this guy had to both astrophysics and pinning muscular dudes to the ground, he says at one point he tried to create a new wrestling hold based on "a phenomenon in orbital mechanics called a double tidal lock," but he could never get it to work.
