Evidence of another world found on Moon

mrspoonsi (2955715) writes "Researchers have found evidence of the world that crashed into the Earth billions of years ago to form the Moon. Analysis of lunar rock brought back by Apollo astronauts shows traces of the "planet" called Theia. The researchers claim that their discovery confirms the theory that the Moon was created by just such a cataclysmic collision. The accepted theory since the 1980s is that the Moon arose as a result of a collision between the Earth and Theia 4.5bn years ago. It is the simplest explanation, and fits in well with computer simulations. The main drawback with the theory is that no one had found any evidence of Theia in lunar rock samples. Earlier analyses had shown Moon rock to have originated entirely from the Earth whereas computer simulations had shown that the Moon ought to have been mostly derived from Theia. Now a more refined analysis of Moon rock has found evidence of material thought to have an alien origin."

But was Earth the Earth before the collision? (1)

If two planets collided which resulted in the Earth and the Moon, could it be theorised that both planets would have been pretty much fscked and the resulting formations contain bits of both planets?

Scientists say that most of the Moon is made mostly from the same material the Earth is made from, perhaps this material is simply what you get when you smash two planets together and the rock found was simply a piece of Theia that had not been completely destroyed during the collision. I'm sure there are pieces of the original Earth to be found as well.

Interesting stuff.

To Hell with all the "evidence"! (0)

How could this have happened 4.5 billion years ago when the universe is only about 4000 years old so sayeth the book I read written by somebody I don't know who claims everything in it to be true so therefore it must be?
