RE: Nuclear Planet in DISCOVER
I am no geologist by any a stretch of the imagination, so you will have to
forgive me for asking more questions.
Shouldn't this theory be able to be applied to other planets? If the
elements in the pre-planetary accretion disc were stratified by gravity,
wouldn't Venus and Mercury have a high chance of having a higher
concentration of fissionable isotopes in their core? If the nuclear core
is a product of your position in the solar system how does Jupiter manage
to generate so much heat? Also, how does a five mile ball of uranium fit
into the model of earth's estimated mass?
Also, what does this do for those long lived "naturally abundant" isotopes
on our planet which are not part of the natural decay series? Are they
early fission products or cosmogenic?
To bad we don't have any planetary geologists on the list. I knew one but
lost track of him a few years ago.
More semi-ignorant ramblings from yours truly.
