Most of that geology I can accept, given the melting and crustal movements. But, admittedly, coordinating the simultaneous explosions of 10^40 supernova's is a bit tough.

And, as stated, today's physics and mass-energy do a pretty good job of explainig what's happening right now.
Melting and crustal movements can explain a lot, but they don't explain how randomly distributed gold atoms coming out of a supernova cluster together into solid nuggets on our planet.
That's a violation of the Law of Gaseous Diffusion, analogous to "flatulence" diving back into your trousers after everyone in the room has smelled it.
