Okay, dude. I've provided proof now, so there's not much else I can do. Real life physics or not(which it never really is, anyway), Stan Lee himself explained the concept...can't really say he's wrong when the man created the concept. But you believe what you choose, of course.
It was never meant to be taken as literal science, but like most of Marvel's early heroes, Stan wanted to explain their abilities through pseudo-science. Mjolnir is enchanted, so of course it's not going to be completely anchored to our human laws of gravity. That was never the intention.
