About the video carbon dating accuracy:

At this point, the carbon dating data is simply disregarded. Uranium-Thorium Dating Dr. Marine records, such as corals, have been used to push farther back in time, but these are less robust because levels of carbon in the atmosphere and the ocean are not identical and tend shift with changes in ocean circulation. Despite this she continually uses the c14 dates to create 'absolute' chronologies.

In , he had one.

Credit: Mari Cleven They were studying a little atom called carbon Also known as radiocarbon, carbon is a radioactive isotope of carbon with an atomic nucleus of six protons and eight neutrons. Thus Carbon is found in very low levels in the fossil fuels produced from plants and the animals that eat them.

Name is tagged in the video. It has been for months. It would be quicker for me to just type the name, but this video has 18 million views. It's been here long enough for her name to be tagged. You are able to comment, which means you know how this website works. Either you're trolling or you're a lazy s.o.b.

But our work indicates that it's arguable their fundamental basis is faulty -- they are using a calibration curve that is not accurate for this region. But for individual humans—and entire civilizations—it does not. Organisms capture a certain amount of carbon from the atmosphere when they are alive. Unlike Carbon, this isotope of carbon is unstable, and its atoms decay into an isotope of nitrogen over a period of thousands of years. In addition to his work as an astronomer at the UA's Steward Observatory, Douglass was the first to discover that tree rings record time.

In other words, those hoping that uncertainties in radiocarbon dating, say in the assumption of constancy of atmospheric carbon levels, will mean that specimens are really much younger than the measured dates, are in for a big disappointment -- it is now clear that specimens are actually somewhat older than the raw, uncalibrated reckonings. Now, if this carbon dating agrees with other evolutionary methods of determining age, the team could have a real discovery on their hands. I just listened to a series of lectures on archaeology put out by John Hopkins Univ.

Radiocarbon dating is based on the fact that the interaction of cosmic rays from outer space with nitrogen atoms in the atmosphere produces an unstable isotope of carbon, namely radiocarbon. These curves indicate the changes in Carbon throughout the years and modifies the end result of the tests to reflect that. However, in the scientific results mentioned by Brown, the dates come from different mammoth specimens. He understood that archaeological artifacts were readily available.
