Carbon dating physics

This method is based on the idea of radiative decay of Carbon isotopes over thousands of years. Through physics, scientists have discovered that radioactive molecules decay at a specific rate dependent on the atomic number and mass of the decaying atoms. Scientists have concluded that very little change has occurred in the ratio of Carbon to Carbon isotopes in the atmosphere meaning that the relationship between these two should be very similar to how they remain today. Carbon dating is a revolutionary advancement in the study of the history of our planet.

Although 12 C is definitely essential to life, its unstable sister isotope 14 C has become of extreme importance to the science world.
