Could radiometric dating be wrong


It looks like this: Most of the other measurements for the age of the Earth rest upon calculating an age for the solar system by dating objects which are expected to have formed with the planets but are not geologically active (and therefore cannot erase evidence of their formation), such as meteorites.Below is a table of radiometric ages derived from groups of meteorites: As shown in the table, there is excellent agreement on about 4.5 billion years, between several meteorites and by several different dating methods.Some of these rocks are sedimentary, and include minerals which are themselves as old as 4.1 to 4.2 billion years.Rocks of this age are relatively rare, however rocks that are at least 3.5 billion years in age have been found on North America, Greenland, Australia, Africa, and Asia.A young-Earther would object to all of the "assumptions" listed above.However, the test for these assumptions is the plot of the data itself.

If the solar system formed from a common pool of matter, which was uniformly distributed in terms of Pb isotope ratios, then the initial plots for all objects from that pool of matter would fall on a single point.The higher the uranium-to-lead ratio of a rock, the more the Pb-206/Pb-204 and Pb-207/Pb-204 values will change with time.If the source of the solar system was also uniformly distributed with respect to uranium isotope ratios, then the data points will always fall on a single line.(I believe this argument was originally put forth by Mormon young-Earther Melvin Cook, in a letter to the editor which was published in .) But helium can and does escape from the atmosphere, at rates calculated to be nearly identical to rates of production.In order to obtain a young age from their calculations, young-Earthers handwave away mechanisms by which helium can escape.While these values do not compute an age for the Earth, they do establish a lower limit (the Earth must be at least as old as any formation on it).
