Problems with radioactive dating methods Israeli live sex cam free

other isotope pairs cover intermediate time periods between the spans for carbon 14 and uranium.Some radiometric dating methods depend upon knowing the initial amount of the isotope subject to decay.There are about two dozen decay pairs used for dating.Uranium 235 decay to lead has a half-life of 713 million years, so it is well suited to dating the universe.Let us critically examine each of these claims and see if they hold up against the science.While doing so, we will have to learn about how radiometric dating works.A very common claim of young earth creationists in trying to reject the evidence for an old earth is to loudly proclaim that radiometric dating methods “makes assumptions” and that these “assumptions” are somehow fatally flawed or not supported by evidence.These claims generally land in three different categories: (1) radiometric dating assumes that initial conditions (concentrations of mother and daughter nuclei) are known, (2) radiometric dating assumes that rocks are closed systems and (3) radiometric dating assumes that decay rates are constant.

Those isotopes that are not stable decay into daughter nuclei.First, it provides no evidence whatsoever to support their claim that the earth is very young.If the earth were only 6000–10 000 years old, then surely there should be some scientific evidence to confirm that hypothesis; yet the creationists have produced not a shred of it so far.Most young earth creationists reject all of these points.As a scientific skeptics, we ask ourselves: is this really the case?This is an important topic, for evolutionists want the history of earth to span long ages in the hopes that this will make the origin and evolution of life more likely.
