You've said you disputed them, but you haven't put forth any good sources which dispute them, and you haven't demonstrated the sources I have put forth to be incorrect. You may have disputed them in your mind, but in objective reality, not so much.

You did that before you even looked at them, so I hardly think restating your pre-biased opinion is proof of anything. Indeed, how can you possibly know i'm wrong before you've even looked at what I had to say?
I HAVE looked at what you have to say. Knowing that gravity is a fact before you try to sell me a can of Upsidaisiun is not a pre-biased opinion,
