General process of radiometric dating Live german webcam sex
The time required for half the original number of parent atoms to decay is called the half life.Some half-lives are listed below: It follows that uranium-lead, potassium-argon (K-Ar), and Rubidium-Strontium (Rb-Sr) decay can be used for very long time periods, whilst radiocarbon dating can only be used up to about 70,000 years. This uses a simple exponential decay formula linking the original number, Po, of parent atoms in rocks and minerals to the P atoms now present, thereby enabling an estimate of geological age.Some claim Genesis in particular, and the Bible in general looks mythical from this standpoint.A full discussion of the topic must therefore include the current scientific challenge to the OE concept.But YE scientists point out some anomalies in relation to C-14 and a very old earth.
This is based upon the spontaneous breakdown or decay of atomic nuclei.
In fact, organic samples from every portion of the Phanerozoic record (spanning the last 500 million years on OE dating) show detectable amounts of C-14.
The implication is that this organic material was either contaminated by new C-14, or it was buried much more recently and OE dating methods are suspect.
This implies the earth is at least 20 million years old.
Astronomical cycles can also be used to measure relative age.
