Of course, this was a close as Kelvin ever came to publicly recanting his position.Later, after radioactivity had been proven to be a significant source of the Earth's internal heat, he did privately admit that he might have been in error."The fascinating impressiveness of rigorous mathematical analyses, with its atmosphere of precision and elegance, should not blind us to the defects of the premises that condition the whole process.

Interweaving the relative time scale with the atomic time scale poses certain problems because only certain types of rocks, chiefly the igneous variety, can be dated directly by radiometric methods; but these rocks do not ordinarily contain fossils.As one answer to his critics, Kelvin produced a completely independent estimate -- this time for the age of the Sun.His result was in close agreement with his estimate of the age of the earth.Some, like Robert Gentry, have even argued that Radio-halos from rapidly decaying radioactive isotopes in granite seem to indicate that the granites were formed almost instantly.Of course there seem to me to be fairly reasonable explanations for this observation which may allow for more slowly forming granitic rocks.
