The only known and indisputable fact is that we know near to nothing about what is going on and what will happen on a cosmic level. I would put it this way, 99.99999...% of what is said here and the rest of the web about what is going on and what will happen, how the universe works, the big bang and dark matter, empty space talk etc. etc. is basically speculation, a journey in exploring our mind - we simply don't know, the scientists doesn't know really, what they know is a lot of math and to some extent how parts of universe works in theory. Mind you that basically all "facts" from quantum physics comes out of a man made mini environment replicating nature to the best of there ability. No doubt many great brains involved there but... with some perspective one can ask "why are they still playing in the sand-pit and not with the big boys out there?
With that said, some speculations might be right and there is nothing wrong with exploring the mind, but I think it will take until 2011/2012 before we really start to get it - and probably we will be very surprised.
[edit] Yes it's very frustrating that we have to wait, so really great we have this place to help us through.

So to sum it up the "indisputable proof" presented here is no more facts then what is
presented here in Mayan Calendar Explained and although I find this with quantum physics interested in many way, I would still put my bet on the Mayan Calendar.
