The claimed “fact” that decay rates have always been constant is actually an inference based on a uniformitarian assumption.It is true that radioisotope decay rates are stable today and are not largely affected by external conditions like change in temperature and pressure, but that does not mean that the rate has always been constant.

It is possible to measure the ratio of the different radioactive parent isotopes and their daughter isotopes in a rock, but the ratios are not dates or ages.

The dates must be inferred based on assumptions about the ratios.

Uniformitarian geologists use so-called dating methods to determine the ages of the surrounding rocks.

Certain types of rocks, especially those that form from magma (igneous), contain radioactive isotopes of different elements.

There is also a difference in the timescale used to explain the layers.

Determining the relative age of a rock layer is based on the assumption that you know the ages of the rocks surrounding it.However, there are many methods that can be used to determine the age of the earth or other objects.The textbooks focus on relative dating, based on the layering of the rocks, and radiometric dating.Some of the common isotope pairs used are K-Ar, Rb-Sr, Pb-Pb, and U-Pb.Carbon-14 dating is another common technique, but it can only be used on carbon-containing things that were once alive.If any of these three conditions is not accurately known, the hourglass will give an inaccurate measure of time.
