I added the following to the "Responses to criticisms" section today:

* ''Zircon crystals found in Jack Hills (located in Western Australia) have been found to have such a ratio of uranium to lead that their formation must have occurred at least 4.404 billion years ago.  While some processes of radiometric dating can be innacurate (as in the case of the RATE project, where researchers conducted an experiment to show that the experiment they were conducting could be conducted incorrectly, the radiometric dating of these crystals is much more accurate than radiometric dating is because we know that uranium does chemically bond to the zircon crystals while lead does not.  The only way the lead in the crystals found in Jack Hills could exist in such quantities as observed in the crystals is that it is the result of the atomic decay of the uranium in the crystals.  Many defenders of Young Earth Creationism refute radiometric dating by saying that we don't know how the Earth was thousands of years ago, so we don't know that the decay rates of these atoms are "constant".  This assertion is refuted by the fact that the only way to affect the probability that an atom will decay at any given instant is to introduce a strong source of gamma radiation (which is not found on or near Earth naturally).  ''

Since I have explained what my addition means as Philip J. Rayment requested, and if there are no immediate objections, I will be replacing this in about an hour, but not before letting the director of the physics laboratories at Florida Atlantic University proof read it if he is in his office.  I am a physics undergraduate student at FAU, in case anyone was wondering.  --[[User:MichaelK|MichaelK]] 16:43, 29 April 2008 (EDT)
