Re:There is no contradiction. (Score 1)

Nobody is denying that time flows differently according to the speed of the reference frame. This is not what opposes YEC (young earth creationists) and contemporary astronomy : their question is how many rotations did the earth looped around the sun since its existence ? Now even without knowledge of Michelson-Morlay formulas, it's obvious that they don't change this NUMBER ! So your Langevin twins story is completely irrelevant here.
