Any nerd worth her NaCl knows all about English comedy group Monty Python, and their version of the King Arthur legend, “Monty Python and the Holy Grail.” But lesser known are the troupe’s other feature-length films, including 1983’s “The Meaning of Life.” Amidst a dinner party with Death and a machine that goes “ping!”, audiences are treated to one of the weirdest, most catchy astronomy tunes out there: The Galaxy Song..

It’s a true earworm (I’ll have the song stuck in my head for weeks now), but just how accurate is the science?
