Here is a bit more information on the next events that may have happened after the Mars incident 😉

From the remains of the impact, a giant ball of magma coalesced in Earth orbit. Gravity sculpted this hot mass into a sphere. In time, its surface cooled, forming a hard crust with magma just underneath.

Around 4.3 billion years ago, a giant impact battered the moon’s south pole, sending debris as far as the opposite side of the moon. The impact formed the Aitken basin.

It is pretty amazing that mathematical models of orbits and surface analysis could yield such a conclusion.

Are they right?  Do you feel strongly one way or another?  If so feel free to comment.
