I'm stuck on this idea. How are initial radioactive isotope quantities assumed in radiometric dating? There are current abundances for all isotopes, but wouldn't these abundances have been different in the past (much higher)? I honestly can't grasp how radioactive isotopes with short half lives can even exist today, given the age of the Earth. Can someone set me straight-- Google isn't cutting it.
Thank you.
Thank you.
