But that assumes that the amount of carbon-14 in the atmosphere was constant — any variation would speed up or slow down the clock.
The clock was initially calibrated by dating objects of known age such as Egyptian mummies and bread from Pompeii; work that won Willard Libby the 1960 Nobel Prize in Chemistry.
Many people are under the false impression that carbon dating proves that dinosaurs and other extinct animals lived millions of years ago.
What many do not realize is that carbon dating is not used to date dinosaurs. Carbon dating is only accurate back a few thousand years.
If you cannot be omni-present, which would be required for such a feat, then all you can do is put a guess on the number.
One cannot even conceive of how such a task could be accomplished with mankind's limited ability, and that is for something we can see (e.g.
They ignore evidence that does not fit their preconceived notion.Very Little Sediment on the Seafloor Due to Plate Tectonics, ocean floor is continuously created at mid-ocean ridges and subducted into the Earth’s mantle at ocean trenches.This process moves at about an inch or two per year, so the average age of the ocean floor is in fact a few tens of millions of years, and thus the result is completely consistent with old-Earth science.Carbon dating is used to work out the age of organic material — in effect, any living thing.The technique hinges on carbon-14, a radioactive isotope of the element that, unlike other more stable forms of carbon, decays away at a steady rate.
