Perhaps someone knows... The more massive the gravitational field, the more time dilation, yes? The farther out you go the less drastic the effect is. Could the rotation just appear (to our frame of reference) to be moving not as fast in the middle (where the gravity is strongest) even though it is moving as it should according to our theories?
IINAP (and I'm guessing you're not, either). I used to think of things like this and say, "gosh, couldn't this be the explanation?" Then I remember that there are thousands of experts in the field, and it is extremely improbable that me, a layperson in the field, has thought of something -- especially something relatively (pun intended) simple -- that an expert hasn't thought of and obviously debunked (because we would have read about it were it plausible).
That said, I don't understand the physics behind gravity wells and their relation to time dilation very well, so I would be interested to hear from one of the aforementioned experts why it's not as simple as Taibhsear has made it sound!
