New Theory: A “Hit and Run” Accident Created Our Moon

How did Earth get its own Moon? For decades, the most popular origin story has been the “Big Splat” theory, which says an object the size of Mars impacted the Earthmore than three billion years ago, flinging material into space which became the Moon.

But now there’s new evidence that the Big Splat theory may be incorrect — and the impact that created the Moon may have been more like a hit-and-run accident.

Read the full study in Nature Geoscience.

Not really that new, but interesting nevertheless.
