(These include the variety of elements used in ‘standard’ radioisotope dating, mature uranium radiohalos and fission track dating.) It would be hard to imagine that geologic processes alone could explain all these.Rather, there was likely to be an answer that concerned the nuclear decay processes themselves.Others had tried to find an answer in geological processes—e.g.the pattern was caused by the way the magma was emplaced or how it crystallized. But Drs Humphreys and Baumgardner realized that in other cases there were many independent lines of evidence that suggested that huge amounts of radioactive decay had indeed taken place.Here you can discover the power of geological processes.efore analyzing the arguments advanced by creation “scientists” for a very young Earth, I here summarize briefly the evidence that has convinced scientists that the Earth is 4.5 to 4.6 billion years old.

While our name does come from a German U-boat from WWI.

The U-18Chan community came from an older community of the Aurorafurries which came from Aurora Chan in 2006.

In early 2006 a community formed around the newly created /fur/ board on Aurora Chan of furries drifting over from 4Chan's /b/.

Some evidence is also presented to show that radiometric results that are in agreement with the accepted geological time scale are selectively published in preference to those results that are not in agreement.

The geological time scale and an age for the Earth of 4.5 b.y.
