Many rocks and organisms contain radioactive isotopes, such as U-235 and C-14.
These radioactive isotopes are unstable, decaying over time at a predictable rate.
Most people today think that geologists have proven the earth and its rocks to be billions of years old by their use of the radioactive dating methods. Given so much time, the ‘impossible’ becomes possible, the possible probable, and the probable virtually certain.
Ages of many millions of years for rocks and fossils are glibly presented as fact in many textbooks, the popular media, and museums. One has only to wait: time itself performs the miracles.”1 Yet few people seem to know how these radiometric dating methods work.
A commonly used radiometric dating technique relies on the breakdown of potassium (Ar in an igneous rock can tell us the amount of time that has passed since the rock crystallized.
Each atom is understood to be made up of three basic parts.
The nucleus contains protons (tiny particles each with a single positive electric charge) and neutrons (particles without any electric charge).
Orbiting around the nucleus are electrons (tiny particles each with a single electric charge).
Fossils are collected along with rocks that occur from the same strata.
These samples are carefully cataloged and analyzed with a mass spectrometer.
