The isotopes Tellurium-130 (130Te) and Selenium-82 (82Se) are known to undergo double beta-decay, a process in which two neutrons change into two protons with the emission of two electrons and two antineutrinos. The half-lives for these processes are some of the longest half-lives ever measured, meaning that such decays happen only very slowly. In calculating these half-lives from theory, physicists assume that certain laws of physics have operated in a well-formulated manner.  In inferring the age of a rock using these decays, one must assume that the laws of physics have operated the same over the lifetime of the rock.

In science, and particularly in physics, it is easy to fall into the trap of thinking that there are principles outside of God, which we call “laws,” to which God must necessarily be subject. In a sermon of July 3, 1881, C. Spurgeon addressed this subject:

God’s word is the manifestation of his secret thought. By it he reveals his decree; by it he manifests his nature; by it he carries out his purpose…Our wise men are continually talking of the laws of nature, and we know that there are such laws, or, in other words, it is a fact that God usually acts in such and such a way; but to suppose that there is any power in the mere laws of nature is absolutely absurd. You may make laws in your household that things are to be done in such and such a way; but unless somebody carries them out laws are nothing. . . (Spurgeon, 1971, pp. 377–378)

Spurgeon was right on track. The accelerated decay hypothesis asserts that halflives of radioactive elements changed at certain periods in the history of the earth, including perhaps that decay rates were much larger during the Genesis Flood…
