Sorry guys if you have already covered this subject but someone the other day mentioned time wells and different frames of reference etc. and I was wondering: If time slows down the more massive and dense things are then how can that effect the observer's perspective? In other words when we view distant galaxies is our perspective (in relation to time) dictated by our position (in relation to density)in our own galaxy? Close to the center of a galaxy time is slower and at the far edge of a galaxy time is faster. The subject of time is hard enough but if time dilations are true then how would that effect our view of say a distant galaxy? If the center of a distant galaxy is in a slower time dilation (in relation to us) do we see the center section rotating slower than it actualy is and do we see the outer areas moving faster than they actually are? If our perspective were from between galaxies or some other area where density was very low how would everything around in the distant appear to move? Would everything be blueshifted? Would it effect the way the rotation appeared? Etc.
