[Space.com] Earth Had Two Moons That Crashed to Form One

post #1 of 53

A tiny second moon may once have orbited Earth before catastrophically slamming into the other one, a titanic clash that could explain why the two sides of the surviving lunar satellite are so different from each other, a new study suggests.

The second moon around Earth would have been about 750 miles (1,200 kilometers) wide and could have formed from the same collision between the planet and a Mars-sized object that scientists suspect helped create the moon we see in the sky today, astronomers said.

I think this is pretty interesting. It's amazing how we can figure this stuff out and be able to test the ideas with computer models!

No one could possibly no this but its very interesting thanks for the read. The moon definitely has some interesting theories attached to it.

I don't think you know what a conspiracy theory is, because this definitely doesn't involve one. The moon is the moon, unless you're thinking that the world's government powers built the moon and sent it up there during the Cold War as the space race goal.

Conspiracy theories? This is pretty good science I would say! You are right that they can't prove it without any doubt but the data backs up the theory so far!

I think he means conspiracy theories involving the moon. e.g. the Moon landing.
Some people think it didn't happen. Crazies

O please they cant prove this any better than the hollow moon theory or others...All im saying is there are alot of interesting stories involving how the moon came about. And more than one involving good science lighten up.

Kooks, I tell ya.

The only real conspiracy that seems sounds enough is that the moon is a base for David Icke's reptiles.

This is just one hypothesis/thoery
I am still clinging on to the meteor smashing into earth and the chunks of earth that blasted out formed the moon theory.
