Radioactive dating time change
Due to the extremely short half-lives of the Po isotopes, this would present a serious problem for those wanting to date the rocks at millions or billions of years old.Diffusion rates of the Thus, the observed evidence in rocks extracted from the earth’s crust present several conundrums—problems that center on assumptions made in using radioisotope decay within a rock sample as a clock to date the origins of that sample.The process of radioactive decay can be envisioned as an hourglass implanted in a rock suite.
These radiohalos originate from tiny point-like inclusions of U or some other naturally occurring radioisotope within the crystal.
Unfortunately for the secularist, there are radiohalos formed from what appears to be primordial Po (polonium), rather than Po in the form of daughter isotopes from U decay.
By the mid-1940s, Willard Libby realized that the decay of C research—his life’s work—Libby was awarded the Nobel Prize in Chemistry in 1960, and the age of radioactive dating was born.
Before we delve into radioactive decay and its use in dating rocks, let’s review some essential nuclear physics concepts.
This perspective, generally termed the uniformitarian view of nature, constitutes a pillar of the secularist’s worldview and is fundamental in generating the concept of deep time in the origins discussion.
