Different radiometric dating techniques

In some cases radioactive decay itself can be observed and measured in distant galaxies when a supernova explodes and ejects unstable nuclei.

Another assumption is that the rate of decay is constant over long periods of time.

With uranium-lead dating, for example, the process assumes the original proportion of uranium in the sample.

One assumption that can be made is that all the lead in the sample was once uranium, but if there was lead there to start with, this assumption is not valid, and any date based on that assumption will be incorrect (too old).

There are a number of implausible assumptions involved in radiometric dating with respect to long time periods.

One key assumption is that the initial quantity of the parent element can be determined.

Because radiometric dating fails to satisfy standards of testability and falsifiability, claims based on radiometric dating may fail to qualify under the Daubert standard for court-admissible scientific evidence.
