The MIT scientists have simply proved that the “moon rock” came from the Earth. They have lent support to the theory that the moon landing was faked.

So what does this imply exactly? I’d gotten the impression that the earth reached close to its current mass 4.5 Gya, and then some little time later, this last big planetesimal came along and some of the debris from the collision formed the moon.

Does this mean that the last big collision was farther back in time, when there was still enough aluminum-26 and whatever to cause differentiation in such a small body? Or would tidal forces pump enough energy into it in slowing it down into captured rotation?

I’m just slinging stuff at the walls here.

Old and worn like the moon herself is truly
Trodden poked and sampled by ‘nauts acting duly.
Who took a rock and put it in a magnetometer
To answer questions magnetic, this time fer sher.

The Moon was once magnetic; but it’s field now is idle,
As it slowly moves away from us; although for reasons tidal.
I feel that somewhere in there, a poem will be born.
But please don’t make me write it; my verse is old and worn.
