Different Isotopes shares the same electron configuration, so are chemically very similar. What I meant is chemical reactions can not alter the weight and charge of the nucleus, which determines the radioactivity of the isotope. So no chemistry can change rate of radioactive decay.
Chemistry can in some cases mobilize either parent or daughter elements. But that's different from changing the rate of decay. Furthermore we know chemistry well enough to exclude this possibility from most radioactive dating. If an volcano boils away daughter elements, it would tend to make the mineral look younger than it is. So it would be All the more embarrassing if the erroneous young age thus derived still exceeds 6000 years by a large margin.
Oh. I see where I was mistaken and this is certainly much more serious a matter.
The only way to change the nucleus of an atom in this fashion at a speed different than radioactive decay would have to involve nuclear fusion or nuclear fission - both of which would either require or generate far more power than is available outside of reactor, a particle accelerator, or the heart of the sun. All of these options would melt the earth.
Even the biggest stars in the universe don't generate uranium until it goes supernova or it hypernovas.
If today you can take a thing like evolution and make it a crime to teach in the public schools, tomorrow you can make it a crime to teach it in the private schools and next year you can make it a crime to teach it to the hustings or in the church. At the next session you may ban books and the newspapers...
Ignorance and fanaticism are ever busy and need feeding. Always feeding and gloating for more. Today it is the public school teachers; tomorrow the private. The next day the preachers and the lecturers, the magazines, the books, the newspapers. After a while, Your Honor, it is the setting of man against man and creed against creed until with flying banners and beating drums we are marching backward to the glorious ages of the sixteenth centry when bigots lighted fagots to burn the men who dared to bring any intelligence and enlightenment and culture to the human mind. ~Clarence Darrow, at the Scopes Monkey Trial, 1925
Politics is supposed to be the second-oldest profession. I have come to realize that it bears a very close resemblance to the first. ~Ronald Reagan
