Young earth creationism radiometric dating
By measuring the amount of uranium and ‘radiogenic lead’ in these crystals, one can calculate that, if the decay rate has been constant, about 1.5 billion years must have passed.
Young earth creationists hold that both creation and the evolutionary position are at root tied to worldviews, and because they are both claims about historical (or prehistorical) events, they depend on untestable assumptions.
Radiometric dating is a method which scientists use to determine the age of various specimens, mainly inorganic matter (rocks, etc.), though there is one radiometric dating technique, radiocarbon dating, which is used to date organic specimens. Basically, scientists take advantage of a natural process by which unstable radioactive “parent” isotopes decay into stable “daughter” isotopes spontaneously over time.
Uranium-238 (U238), for example, is an unstable radioactive isotope which decays into Lead-206 (Pb206) naturally over time (it goes through 13 unstable intermediate stages before it finally stabilizes into Pb206).
In this case, U238 is the “parent” and Pb206 is the “daughter.” Scientists begin by measuring how long it takes for a parent isotope to decay into a daughter isotope.
In this particular case, it takes 4,460,000,000 years for half of a sample of U238 to decay into Pb206.
Question: "How does radiometric dating fit with the view of a young earth?
