C13 carbon dating
Although neutrons do not carry an electrical charge, they have a mass comparable to that of protons, so different isotopes have different atomic weight. Because of the different number of neutrons, carbon-12 and carbon-14 differ with respect to radioactivity. Carbon-14, on the other hand, undergoes radioactive decay:e (half-life is 5720 years)The other common isotope of carbon is carbon-13. "What Is the Difference Between Carbon-12 and Carbon-14? Carbon-13 has 6 protons, just like other carbon isotopes, but it has 7 neutrons. Although 15 isotopes of carbon are known, the natural form of the element consists of a mixture of only three of them: carbon-12, carbon-13, and carbon-14. Measuring the difference in the radio between carbon-12 and carbon-14 is useful for dating the age of organic matter since a living organism is exchanging carbon and maintaining a certain ratio of isotopes. Carbon-12 and carbon-14 are two isotopes of the element carbon.
He directed the pretreatment and processing of the dinosaur bone samples with the Accelerator Mass Spectrometer, though he did not know the bones were from dinosaurs, and he signed the reports.
So when he received another bone sample from the Paleochronology group, he returned it to sender and sent an email saying: "I have recently become aware of the work that you and your team have been conducting with respect to radiocarbon dating of bone.
The scientists at CAIS and I are dismayed by the claims that you and your team have made with respect to the age of the Earth and the validity of biological evolution.
Critics charged that the findings were mistaken or that what she called soft tissue was really biofilm produced by bacteria that had entered from outside the bone.
Schweitzer answered the challenge by testing with antibodies.
After the AOGS-AGU conference in Singapore, the abstract was removed from the conference website by two chairmen because they could not accept the findings.
