Evidence of Protoplanet 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.'

Oh heck no: turtles all the way down, biz-rotches!

That's like asking, "how do we know that the Cretaceous period was called the Cretaceous period, the dinosaurs didn't have written language".

And now we know

Well they have The Doctor and I am sure he knows, he probably watched it happen

Right, while the simplest explanation was "That's no moon..."
