Young earth creationism radiometric dating Adult cam free
Ages of millions of years are all calculated by assuming the rates of change of processes in the past were the same as we observe today — called the principle of uniformitarianism.If the age calculated from such assumptions disagrees with what they think the age should be, they conclude that their assumptions did not apply in this case, and adjust them accordingly.Its only assumption is that the bombardment of the moon was uniform over its surface (not necessarily over time).
The apparent intent of the article is to help other creationists struggling with cognitive dissonance, and for use as a conversion tool.
The assumptions conventionally used in obtaining scientific estimates of the age of the Earth and the universe look supremely cautious compared to such a leap of faith.
The reference to the "way[s] in which the speed of the clock has varied over time" are a very thinly veiled attack on a bedrock assumption of scientific practice, uniformitarianism, in (for the sake of argument) contradistinction to catastrophism.
This is partially true, but there is a crucial difference: the uniformitarian assumptions of science have reasons behind them.
For phenomena which are used in dating, such as the radioactive decay of potassium-40, the observed rate is constant and no known mechanisms of changing the rate exist.
