I'm speaking of the Muon decay experiment which showed no additional gravitationally related time effects in a centrifuge... Firstly does anyone have a real reference for the experiment? All I find are offhand mentions of it. The only identifying info I've gotten on it was that it was in 1966 and I'm unsure of the validity... My question is in trying to understand why a centrifuge has no general relativistic effects. What I've gotten to date is that it is only the gravitational potential that matters. Depth in the field. So does this mean that time effects are the same 30 miles from the surface of the sun as they are 30 miles from the surface of the moon for instance? IE: Intensity does not matter? Does this mean that the Sagnac effect is in no way a gravitational or GR effect? It is explicable in SR terms alone?
