By using carbon 14 dating, scientists can date plants and animals that lived as long as 35,000 years ago.
This is how carbon dating works: Carbon is a naturally abundant element found in the atmosphere, in the earth, in the oceans, and in every living creature. C-12 is by far the most common isotope, while only about one in a trillion carbon atoms is C-14. C-14 is produced in the upper atmosphere when nitrogen-14 (N-14) is altered through the effects of cosmic radiation bombardment (a proton is displaced by a neutron effectively changing the nitrogen atom into a carbon isotope). The new isotope is called
Carbon dating is only accurate up to about 60 000 years. It makes the assumption that the concentration of C-14 in our atmosphere has been relatively constant for the last 60 000 years. If this assumption is correct then carbon dating is accurate. It cannot be used for samples less than around 100 years due to the testing of atomic bombs which altered the 14C levels. Calibration curves are used to date the age of know antiquities (they are mentioned in historical documents so their age can be known). Other than that there are inaccuracies of a few percent as the object gets older than several thousand years.
as far as i know hes not but i know on the show he was dating rosalina
Be sure to read the Natalie Merchant portion as she states they were lovers. == == They were very close friends. As far as dating----no. It is simply a rumor. Sorry folks it never happened.
Not sure how far they date back but I have a 2005 Z Force that is blue in color with grey forks. Really great bikes and built very well.
Geologists cannot use the carbon-14 method to date igneous rocks and dinosaur bones because carbon-14 dating is effective only for organic materials and samples that are less than about 50,000 years old. Igneous rocks form from molten material and do not contain organic carbon, while dinosaur bones, though they are biological in origin, typically date back millions of years, far exceeding the maximum effective range of carbon-14 dating. Instead, other dating methods, such as uranium-lead or potassium-argon dating, are employed for these materials.
50,000 years useing carbon 14
As far back as there were organisms who were able to consume food containing both ordinary carbon and an isotope of carbon; the comparison of the ratios - which pinpoints the time when an organism stopped eating - gives rise to carbon dating.
Carbon dating.Answer 2 OOPs wrong, as the half life of C14 is 5730 years.Off hand I can't think of a dating method (that is used) with such a short usefulness.
The carbon-14 dating method is ineffective for dating dinosaur bones because it can only date organic materials that are up to about 50,000 years old. Dinosaurs went extinct approximately 65 million years ago, far beyond the range of carbon-14 dating. Instead, scientists typically use radiometric dating methods, such as uranium-lead or potassium-argon dating, to determine the age of dinosaur fossils and the surrounding rock layers.
Carbon dating is not useful for dating coelophysis fossils because this method is effective only for organic materials up to about 50,000 years old. Coelophysis lived during the Late Triassic period, approximately 210 million years ago, far beyond the range of carbon dating. Additionally, fossils are typically mineralized and do not contain the organic carbon necessary for this dating technique. Thus, other methods, such as radiometric dating of surrounding volcanic layers, would be more appropriate for determining the age of coelophysis fossils.

As far as I know she is single. Doesn't mean she is secretly dating but probably not.

There is no cut off date. They can go back as far as they wish.
