This is called the giant impact hypothesis, and it gives us a neat explanation for a few curious properties that Earth and the Moon have in common, like identical minerals. There's just one problem.

The accretion hypothesis proposes that the Moon was created along with Earth at its formation. The fission theory suggests Earth had been spinning so fast that some material broke away and began to ...
