Fabian Fnas dis-agrees with this analysis, but however it happened, it certainly involved breaking off a huge chunk of Earth to make the moon, the isotope analysis proves that whether or not it happened like this new theory says.
And I still do.
Further, it's not a new theory, that a chunk of the Earth was thrown off of the crust to form the Moon. It says even that the lack of landmasses in the Pacific Ocean is the proof of the theory, because that's where the chunk came from. Look at the maps! However, this theory is older than the theory of tectonics. The fission mechanism is new, I'll give you that.
That has been a natural fission reactor in work. But it was far from explosive. I cannot think that any natural fission reactor has been explosive during the history of Earth.
I think it's much more plausible that the Moon was formed out of debris after a collision with a Mars-sized planet, early in Earth history. If this theory holds, the future will tell.
