We have a large body of observational evidence of the effect we call gravity. We have {theory\on theory\on theory} built up from empirical data formulas to theories of how gravity acts and is effected. But as for evidence for how that {action\effect} actually {works\becomes\exists}, whether via space warping, gravity waves or gravitons or some other method, we have ... what? Theory.
No, you have misunderstanding as evidenced by this paragraph. New topic on its way... soon.
Stating that science knows more than it knows does, imh(ysa)o, play into the hands of those that claim that science is dogmatic and not ammenable to change.
True, but you are talking of what you do not know. I know you say that you read Einstein, etc, but your massive ignorance is demonstrated in the quoted paragraph. I don't mean this as an insult or to be in any way derogatory. Very few have a good understanding of this. You CANNOT gain anything close to sufficient undestanding from popular science and/or the internet to make the above claims. If I showed your posts around my old group or any others there would be howls of laughter.
You are not in a position to comment on the validity of GR. Just your simple confusion of GR with cosmology is ample evidence of this. Please be careful with your comments...
With respect
