Researchers have published a new "collision chain" model for the Great ... uses machine learning to build predictive models from 3D simulations of giant impacts. The team tested their predictive ...

The formation of the moon has long remained a mystery, but new studies support the theory that the moon was formed from debris left from a collision ... are rooted in the chemistry of the moon.

Debris from the collision mingled together and then settled ... more of the remains of the original impactor in the Moon. The chemistry of Moon rocks would be different from that of Earth rocks.
