Just how reliable, then, is this radiometric method for estimating the ages of fossils? High-energy cosmic rays (actually sub-atomic particles) from space continually crash into atoms in the earth’s upper atmosphere.The result of such a collision is a shower of sub-atomic debris, including many neutrons.It subsequently evolved into the most powerful method of dating late Pleistocene and Holocene artifacts and geologic events up to about 50,000 years in age.
The radiocarbon dating method was developed in the 1940's by Willard F.
Libby and a team of scientists at the University of Chicago.
Recall that atoms are the basic building blocks of matter.
Atoms are made up of much smaller particles called protons, neutrons, and electrons.
A common question concerning the creation-evolution controversy is “What about carbon-14 dating?
