We can work out what will happen as a result of various gravity "set ups" using GR (or Newton) such that we can say what things will do... fall fly stuff... what but Newton and Dr A avoided was any consideration upon how gravity actually works..
AND before you all cry out DR A knew it all I say this ...no one will take up or answer the following question...
What is general relativity..is it any more than a sum???, and if so where is the briliance if there is no comment upon the way it works..
I saw someplace.. that general relativity is like a pythagarian theorum with a negitive line for time...whatever how else can you think about the universe.... but upon my understanding it does no more than "measure" ..and if it explains gravity then I dare anyone to explain gravity within that theory such to offer commentary upon what is going on .....
What is the premise of GR? why can that not be put in a statement simply explaining why and how gravity works...easy...easy that is if GR does half of what it claims... but explain gravity it does not! We get to think spacer is a mystery with time and bending but it takes away from the fact no one has expalined how gravity works... to much talk such we miss what we ask I feel... assume the sums are right etc..assume I accept the premise without math prove...just tell me...what is the premise of GR..in a sentence or two.
so how does gravirty work...no one knows is the state of science today...but one thing is certain..general relativity is not what makes it work... GR holds no joy and says zip really... so who will venture a consise statement as to what general relativity says.... what?..if space and time is being bent please explain the physical mechanism..it does not happen because a formula says it must.. the formula only gives an insist as to expected results etc.
How does attraction work???... until someone says how it works how can we entertain dark matter...the only reason we need dark maTTER IS BECAUSE WE RELY ON A MYTHICAL FORCE..ATTRACTION..TO EXPLAIN THINGS.. sorry hit caps.. not shouting..
You can add dark matter until the cows come home it wont fix the problems but only makes it worse as the more you add the more you have to add ... think how will dark matter and attraction solve the fast outter star thing..it wont because it can not..
Gravity pushes irrespective of how your sums try to command it and accepting that it does push makes all things reasonable, managable..we dont need matter we that can not see or universes in parrallel or the crap that flows in the absence of a considered assessment of the matter we deal with.

If we know so little about gravity Alex, how did those ignorant twits at NASA fly their probe through the Cassini division?
