If you thought Neil deGrasse Tyson hated "Gravity" -- and he seriously did -- wait until you hear him shred an obscure Disney sci-fi movie from the 70s that still angers him to this day.
The host of “Cosmos: A Spacetime Odyssey” was outside the Paley Center in NYC Wednesday night ... when we innocently asked him to name the most scientifically inaccurate movie in history.
Tyson immediately went HAM on 1979's "The Black Hole." If you're a fan of it ... you might want to look away.
He also weighs in on the old "Armageddon" vs. "Deep Impact" debate ... and told us about his awkward meeting with "Gravity" director Alfonso Cuarón.
