There have been a host of settled science, that turned out to be completely wrong.

Neil is a fraud. I'm sure he is smart, but he is just saying some of the dumbest stuff possible, often. Remember when he said BB wouldn't work in sand, the physics wouldn't allow it? Then they said, "yo dawg, that's how it works on the set."

People still listen to that idiot, with that one real time oopsie.
