Exactly the point of this thread!
It has to do with theory, proof, fact, etc. However, if concerned pink elephants that wouldn't make your blatant contradiction any less an indication that you haven't the faintest idea what you are talking about (and that, despite your reliance on arcane assertions so as to avoid any need to defend your viewpoint, you've still indicated you contradict yourself).
I know gravity is real.....that's a fact.
I don't have to prove it.....that's a fact.
Good ideas need proving to become fact.
These are your words, your assertions, your claims. They are a clear indication that you can't even manage to keep your own views straight. You contradict yourself. So why should anybody take your nonsense seriously?
