Let’s say you were a zombie, and you were watching The Walking Dead, and you think in your zombie brain, “Braaaaaaaaain? Zombies want braaaaaain.” [Translation: Why don’t the zombies ever eat the brain on the show? That’s the most delicious part!] Or you’re Marcus Aurelius and you’re watching Gladiator and you’re like, “Hey, wait! I didn’t die like that!” It’s the same feeling Neil deGrasse Tyson gets when he watches science-fiction movies.
