Young earth radiometric dating yellow pages to find dating sitesi

The three key underlying assumptions are 1) the rate of decay of parent into daughter has remained constant throughout the unobservable past; 2) the specimen which we are examining hasn’t been contaminated in any way (that is, no parent or daughter has been added or taken away at any point during the unobservable past), and 3) we can determine how much parent and daughter were present at the beginning of the decay process – not all of the Pb206 present today necessarily came from decaying U238; Pb206 may have been part of the original constitution of the specimen.If any of these assumptions are wrong, the method cannot accurately determine the age of a specimen.Shall the declarations of the Scriptures be dismissed merely because some are intimidated by the assertions of skeptical scientists who are committed to the theory of evolution?And make no mistake about it, the lust for time is paramount in the Darwinian scenario of origins. Robert Jastrow, one of America’s more popular scientists, says: “The key to Darwin’s explanation is time, and the passage of many generations” (1977, 112; emphasis added).…Results show that because of all the helium still in the zircons, these crystals (and since this is Precambrian basement granite, by implication the whole earth) could not be older than between 4,000 and 14,000 years.

We pose these questions for reflection: If these questions can be answered affirmatively—and we are confident they can—then the testimony of inspiration must be respected.

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).

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.

(This is consistent with the geologic ‘age’ assigned to the granites in which these zircons are found.) There is a significant amount of helium from that ‘1.5 billion years of decay’ still inside the zircons.
