Elements stratify by density and if what is known on earth is applied to the sun then an assumption can be made that the lightest known elements will be on the outer surface of a celestial body and the densest at its core. Uranium and other radioactive matter are the denser elements known to man, and hydrogen is the least dense so it would make sense that the sun has a super dense radioactive core and a foamy hydrogen surface. "Science" makes conclusions about the Sun based on what radiometric spectra its surface emits... Sadly this reasoning is as profound as if one were peering down on Earth through a space telescope and determining the engine under the hood of a parked car based on the color of its paint. All that to say there may be some substance to what Mr PHD has stated.
