Living organisms absorb a proportional amount of radioactive carbon fourteen isotopes to what is constantly present in the earth’s atmosphere.When that organism dies, the carbon fourteen decays at a known exponential rate: making it possible to calculate the approximate time when the organism died based on how much carbon fourteen remains in a sample of the dead material.Presented in the journal Angewandte Chemie, their electroanalytical method is based on the voltammetry of microparticles.It compares various corrosion products that form over long periods of time and works with only a few nanograms of material so it causes almost no damage.Dates could be assigned based upon scientific evidence rather than on the inconsistent mathematics, historical comparisons and simulated typologies of artifacts that had previously regulated time.The most well known and oft used form of radiometric dating is radiocarbon dating. It has helped define the ages of man in ways never thought possible and led the way for a vanguard of scientific techniques that have further defined time for humanity and beyond.For periods without a historic record, attempts have been made to categorize tool kits, pottery styles, and architectural forms into regional timelines.Some ill-fated attempts to define time even attempted to count backwards through the genealogies of the Bible, establishing a series of dates which remain a cause of confusion.
According to the Gregorian calendar, it is the year 2009 AD. The Kaliyuga Hindu Calendar maintains it is 5110, the Islamic calendar 1430 and the Persian, 2630.
Among other scholarly scientific suppositions, it assumes that the amount of carbon fourteen in the atmosphere has remained constant bar minor recent fluctuations due to the industrialization of the past few centuries and our impact on the environment.
And also, rather importantly, the laws of radioactive decay hypothesize that once a living organism is dead, it no longer interacts with anything in its environment which would affect the speed of its radioactive decay.
These various chronologies and their inherent inconsistencies, known as ‘relative dates,’ are a constant series of hurdles in the quest of historians and archaeologists to record mankind’s existence on earth.
However, in the 1940s, the organization of time was transformed by the revelation of radiometric dating and the subsequent creation of a scientific chronology of humankind, known as ‘absolute dating’.
