What do recent computer simulations suggest about the speed of the Moons formation?
Answer
It could have formed in a matter of hours
Older models of the Moon's formation assumed a long, slow accumulation of debris; however, high-resolution computer simulations have provided a faster alternative. These newer models demonstrate that the debris generated by the massive impact could have coalesced into the Moon in as little as a few hours. This rapid formation allows for more thorough mixing and homogenization of the vaporized material, which helps explain the observed isotopic similarities between the Moon and Earth that were previously difficult to reconcile.
