Both are, however, 'children' of the same parent -- the Zero Point Energy.
Because of this, and because the speed of light is in the numerator of every reduced radio decay rate equation, any changes in the speed of light are indicating changes in atomic decay rates. Importantly, the original short half-life elements were also a contributor and they have gone now.
On pages 186 and 187 he describes the discovery at Oklo in the West African Republic of Gabon, of the remnants of an ancient site where an accident of geology produced, for a while, the conditions suitable for a sustained chain reaction to take place - a sort of natural nuclear reactor.
It was moderated by water permeating a deposit of uranium.
Oklo I've been reading "Impossibility: The Limits of Science and the Science of Limits" by John D.
Barrow and he has an interesting discussion on the speed of light in our geological past.
This then suggests that the majority of the elements were formed at the beginning rather than through a series of supernovae explosions.
Given that point, it seems that the stars must be basically the same age.
However, there are many anomalies and there is much evidence of radioisotopic inheritance and mixing because of global tectonic processes having stirred the mantle and added magmas to the crust, which has likewise been stirred by the crustal rock cycle.My thought is, can the relative natural abundances of these chains' terminal products (Pb208,207, and 206) be used to calculate an initial abundance and time frame for the original atomic abundances of the parent isotopes which could be compared to the predictions of Willie Fowler regarding stellar nucleogenesis processes. Thanks again for all your interesting and informative web postings and work.Setterfield: I believe that it is possible to determine the initial ratios of the parent elements in the various chains.Interestingly, using these sorts of ratios, one piece of moon rock dated as being 8.2 billion years old, to the amazement of the dating laboratory involved.As far as stars are concerned, the Th/Nd ratio has been shown to be unchanged no matter what the age of the star is, which leads one to two conclusions.
