: This is the flaw I see. One observer may stand still on earth but he has moved, ever so slightly, relative to the sun as has our second observer. I don't think Einstein's equations take this tiny difference into consideration, and in dealing with vast distances, the farther out you get the greater the error appears.

: Ack, this is a problem of Frames of Reference (FOR). I hate these.

: The trick is to make your FOR the one in which the Sun is the corrdinate axis, in this case. If you are dealing with objects outside the Solar System then you just choose a FOR that is suitable.

: The idea is that you choose a suitable FOR in which everything experiences these "tiny errors" the same way.

: Relativity works because it allows us to choose the FOR so that all these extra factors can be conveniently neglected to make the maths simpler. We all know that reality is more complex but that only makes the math complex and you still get the same basic answer anyway.

: Yelmalio

Wayne: Yel, don't you think that tiny error within our FOR could turn out to be more pronounced then we assume?
