Be cause U atoms are heavy and migrate under the influence of gravity to the center. Their relative abundance steadily rising.
I don’t know if is it enough to have some effect. But if we discover some exoplanets, hotter than expected, it would be indicative for a process like that.
I don’t know, it just might be, that the radioactivity of a planet rises for a longer time than usually postulated. Certainly, the Galaxy’s atoms are more and more radioactive.
Yes, but why there would be more such reactors today than there were one billion years ago?
