Uranium to lead dating

When a bold maverick, Max Planck, decided to focus on the outlier data, he gave birth to quantum mechanics – a revolutionary new paradigm that changed everything.

The role of prior belief in millions of years in interpreting the rocks to be millions of years old would make a good study.In that last sentence, Corfu warns that researchers could simply ignore discordance out of “convenience.” They could pretend that the problems don’t exist or aren’t important, because it’s too much work to get to the one right answer that Tom Krogh said is the only one that’s good enough.If ignoring the problem becomes the choice of the “collective awareness,” credibility of the U-Pb dating method—or any other method—will suffer as a result.How many discordant dates are simply tossed and never published because they are “obviously wrong”? How often, if ever, do labs perform true blind tests, publishing results with no prior knowledge of the expected date, letting the sample speak for itself? The apparently minor discordances Corfu identified should be re-evaluated in light of what he said about assumptions and interpretations.Creation geologists have submitted blind samples (i.e., not telling the lab what date to expect), and obtained wildly discordant results that profoundly contradict evolutionary expectations. They could be much more important than even he, as an evolutionist and believer in long ages, would admit.Learn about half-life and how it is used in different dating methods, such as uranium-lead dating and radiocarbon dating, in this video lesson. As we age, our hair turns gray, our skin wrinkles and our gait slows.

However, rocks and other objects in nature do not give off such obvious clues about how long they have been around.

So, we rely on radiometric dating to calculate their ages.

Radiometric dating, or radioactive dating as it is sometimes called, is a method used to date rocks and other objects based on the known decay rate of radioactive isotopes.

Behind the confidence of uranium-lead dates hides worry about numbers that don’t match up.

Uranium-lead (U-Pb) dating is a staple of the billions-of-years claims about igneous and metamorphic rocks and meteorites – giving rise to the consensus age of the solar system at 4.55 billion years.

The thing that makes this decay process so valuable for determining the age of an object is that each radioactive isotope decays at its own fixed rate, which is expressed in terms of its half-life.
