Radiometric age dating calculator
Quantum mechanics is one of two cornerstones of modern physics (the other is general relativity), and has been precisely confirmed in thousands of very exacting experiments.For these reasons, scientists have considerable confidence in these dates when they are measured properly in accordance with procedures that have been developed and refined over several decades.This element is locked in tiny zircons within the granite. While it stays within the zircon for a period of time, being a very small atom, helium escapes the zircon within a few thousand years.When creation scientists studied granite samples, they made interesting discoveries.
Uranium-thorium dating, for instance, can be used to date specimens up to about 500,000 years old (since the half-life of the U-Th decay is 75,000 years), but Rubidium-Strontium dating can be used to date specimens billions of years old (since the half-life of the Rb-Sr decay is 48.8 billion years).

The discovery of by the French physicist, Henri Becquerel, in 1896 paved the way of measuring absolute time.
The Half Life Time is the amount of time it takes for half of the atoms in a sample to decay.
Half Life is a characteristic of each radioactive isotope.
