I wonder if pressures at the core-mantle boundary are great enough? Just speculation, but I'm assuming the explosion occurred there and blew material in the crust and mantle outward, leaving the core intact. Thus the moon lacks an iron core.

Right,they're going to have to come up with more evidence to convince me, but... interesting theory.

My understanding of the theory is that this would have occurred prior to the solidification of the Earth. Even if there crust had formed a critical mass of Uranium would be hot enough to melt the crust and rise to the surface.
