What is carbon dating mean?
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
Is carbon dating wrong?
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 Calibration curves are used to date the age of know antiquities (they are mentioned in historical documents so their age can be known).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.

Did Michael Stipe date Natalie Merchant?
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.
How old is a schwinn z force?
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.
How far back can you date fossils by measuring radioactive carbon decay?
50,000 years useing carbon 14
Why cant geologist use the carbon-14 method to date igneous rock and date dinosaur bones?
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.
How far back can carbon dating be used?
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.
Only good for dating objects as far back as about 4000 years?
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.
Why cant they use the carbon 14 method to date dinosuar bones?
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.

What is the accuracy of dating a 500 year old seed and a 1000000 year old bone with carbon 14 dating?
Only the seed could be effectively dated using C14. The bone, at one million years old, is far outside the range for which carbon dating is effective. Once the Carbon 14 within a sample has decayed significantly it becomes impossible to measure the remaining amount and establish an age. Currently, using modern methods we can date items using carbon dating up to around 60,000 years before present. The seed, superficially would be a good candidate for carbon dating, however because of it's age and the process of calibrating radiocarbon dates into calender years there would be quite a large range of dates. If you were to test the seed (assuming is was 500years old) a calibrated age would likely be something like 590-400 years before present with a 95% chance of the age falling within that range, or 430-550 years before present with a 68% chance of the age falling within that range. It is impossible to give a perfect answer to this question without actually having a sample and testing it. Quite often it is possible to be more specific than this, and you typically find dates given within a few decades, although there are variations. When results from a sample come back from a laboratory you may be given several date ranges, each with an associated probability. It is up to the researcher which they feel is accurate enough to include in publication or interpretation.
