How are fossils dated using carbon dating Wechat sex banglore
So in order to date most older fossils, scientists look for layers of igneous rock or volcanic ash above and below the fossil.Scientists date igneous rock using elements that are slow to decay, such as uranium and potassium.So if fossils are really millions of years old, as evolutionary scientists claim, no carbon-14 atoms would be left in them.Indeed, if all the atoms making up the entire earth were radiocarbon, then after only 1 million years absolutely no carbon-14 atoms should be left!Most laboratories measure radiocarbon with a very sophisticated instrument called an accelerator mass spectrometer, or AMS.It is literally able to count carbon-14 atoms one at a time.3 This machine can theoretically detect one radioactive carbon-14 atom in 100 quadrillion regular carbon-12 atoms! AMS instruments need to be checked occasionally, to make sure they aren’t also “reading” any laboratory contamination, called background.
It’s a dilemma for evolutionists, who believe the rocks are millions of years old. Radiocarbon (carbon-14) is a very unstable element that quickly changes into nitrogen.

It is produced in the upper atmosphere by radiation from the sun.
The universe is full of naturally occurring radioactive elements.
Radioactive atoms are inherently unstable; over time, radioactive "parent atoms" decay into stable "daughter atoms." When molten rock cools, forming what are called igneous rocks, radioactive atoms are trapped inside. By measuring the quantity of unstable atoms left in a rock and comparing it to the quantity of stable daughter atoms in the rock, scientists can estimate the amount of time that has passed since that rock formed.Note that, contrary to a popular misconception, carbon dating is not used to date rocks at millions of years old.
