Thank you Steven and thank you Fahim.
Well that site has a straight path and a curved path covered and I am happy with my current understanding..I think
What does bother me is the principle itself... unless I have it incorrect acceleration is related to gravity so as to express it in a force humans can understand but in doing so we let "time" creep into the mix.. I can not see why it is there..its relevance is only so humans can relate the magnitude of the "force" ..er which is not a force by the way
and without it how different will general relativity be then???
I have yet to actually see the 10 field equations..not that it will do much good as I may as well be reading Chinese..I must have seen them at least once someplace by now one would think ..but I can not recall...
As to gravitational lensing... it happens but not the way the mags show it..using the ball and the blanket mentality leaves one misinterpreting it... one day I will post the truth (my version) with some diagrams that will prove my point
