::::: I don't see how it shows a lack of understanding of the methods used to conduct the measurements. You appear to have a misunderstanding, as you seem to be saying that there's only one way of measuring it, which was not available until relatively recent times. But the speed of light has been measured in various ways for 400 years. Granted, the latest method is probably the most accurate, but that doesn't mean that it is the only method that can be used.

::::I'm not saying this evidence is evidence against general Creationism, just Young Earth Creationism. You're right, there are other methods of measuring the speed of light. A more accurate method than what I did exists, but uses modern theories and machinery. It should be very clear to anyone claiming to be smart enough to understand such advanced concepts as radiation propagation that it is very likely that the results of the speed of light measurements conducted centuries ago are the result of major errors due to the reality of light's velocity.
::::As the ''Nature'' article states, the minimum age of those crystals was determined using two isotopes of the same element. Don't you think that it's likely that even if some process existed (other than radioactive decay) that caused lead to enter or leave those crystals would act on both isotopes of the lead?
::::I think it is very likely that these crystals have existed on Earth for more than 4 billion years, and I think anyone must acknowledge that there is at least a possibility that this is true. If you don't think this discussion belongs on the Young Earth Creationism article (though I believe it is responsible to include evidence that refutes YEC if such evidence is valid), then would you object to its addition in the [[Age of the Earth]] article? --[[User:MichaelK|MichaelK]] 11:28, 12 May 2008 (EDT)
