Radioactive dating assumptions Sexchataudio
Radiometric dating utilizes the decay rates of certain radioactive atoms to date rocks or artifacts.
Uniformitarian geologists consider this form of dating strong evidence that the Earth is billions of years old.
The methods are all ultimately calibrated to relative dates of the geologic column, such that data that conflicts with a fossil's or rock's placement in the geologic column is explained away by the evolutionary theoretical system.
For example, Carbon-14 would decay to nothing in well under 1 million years, so if Carbon-14 is found in a dinosaur fossil it is interpreted as resulting from contamination.
These assumptions are based on the axioms or worldview the scientist is operating within.
This worldview is the basis for an entire system of theories.
Age dating the Earth (Geochronology) is the scientific study of the age of the Earth and the temporal sequence of events related to the formation of the planet and the history of life on Earth.
This not only makes the other dating methods look more consistent than they actually are, but it also renders the very existence of the geologic column untestable.It is further theorized that since all isotopes of the same element are chemically identical, they should be removed in proportional amounts, forming a straight line on the concordia diagram, that crosses the concordia curve at both the crystallization and the contamination date.Loss of uranium moves the point up and to the right, while a loss of lead moves the point down and to the left.Concordia dating is a form of uranium/lead dating that uses a concordia diagram.The theory is that when zircons crystallize they lose all of their lead and as long as the crystal remains closed its lead/uranium ratios should follow a predictable trend.
