If you've ever looked up and wondered, how did that 🌔 get there, well, there's a new theory.
An instant moon? That may be how it happened, according to new supercomputer simulations suggesting a giant impact between Earth and a “Mars-sized body” could have put a moon-like body into Earth orbit almost immediately.
“If much of the moon formed immediately after the giant impact,” the university’s report on the findings said, “then this could also mean that less became molten during formation than in the traditional theories where the moon grew within a debris disk around Earth. Depending on the details of the subsequent solidification, these theories should predict different internal structures for the moon.”
