The claim is that was how the excess Carbon, Nitrogen, and Sulfur arrived in the Earths crust, without them being in the core. For instance the Carbon/Nitrogen ratio of 40/1 is twice the 'expected' value.

Finding the answer involved varying the starting conditions, running approximately 1 billion scenarios and comparing them against the known conditions in the solar system today.

That is some kind of study - a billion scenarios.
I have often thought that the moon - er rather the collision that resulted in the Earth - has had a role to play.

Shades of Velikovsky ?

A billion scenarios can be calculated with a supercomputer within a couple of days at most ! A clever algorithm can reduce that calculating time by orders of magnitude !

Shades of Velikovsky would invoke electrostatic forces rather than plain old Keplerian orbital evolution. He didn't "believe" in gravity.
