:: There is less discussion of this in universities than there should be, because quickly it leads to the conclusion of a young earth-moon model. Tides are not the only problem with extrapolating backwards. The moon's orbit itself is unstable, and it wouldn't take much extrapolation backwards before it becomes impossible to fast-forward to what the moon is doing now. For example, extrapolate back far enough and the moon would be drifting towards the earth, not away as currently observed.--[[User:Aschlafly|Andy Schlafly]] 00:54, 22 July 2010 (EDT) | :: There is less discussion of this in universities than there should be, because quickly it leads to the conclusion of a young earth-moon model.
