What is a Scientific Fact, that while you know it has been proven true, still seems impossible?
@RickiTarr I’m going to put my pedantic hat on, and say nobody argues about facts (at least nobody you want to spend any time with).
But we do love arguing about what they mean, and if that meaning seems impossible, you need a better imagination!
Before Archimedes starting shouting Eureka, I suspect he said wtf?
