I can not see the relevance of time in some respects
.
Space time for me describes space via human geometry without coment upon the physical make up of space... and I point out that I am talking from the view of an ignorant layman and standing outside a house does not allow one to understand what may go on inside same
...
still it seems to me that gravity has been linked unnecessarily with time in the hunt for an understanding of gravity...
I have not even seen the equations (11 I think setting up for GR) but I already suspect that time crept in via the principle of equivalance... which relates gravity to humans sums and human experienence in a quantifiable state for contemplation on a 2d sheet of paper... and that is great that is a big achievement of that there is no question...
but still do we need t in the mix one wonders...GR would not work I guess without it...
T is necessary for humans and it seems that the Universe includes T in things... simply time means everything does not happen at once
...which one would imagine would be the case of no time...mmm...but does gravity worry about T
..it does what it does at the fastest speed in the Universe C so does graviy need to know about time??
But maybe we leave T in general relativity for the moment
