More Problems with Carbon-14 and Old-Earth Assumptions
But save the source of the game according detected, all they have are available claims. The drinks:.
If you find a fossil in the dirt, the amount of carbon 14 can be measured and the rate of decay can be determined. However, that is all that can be determined. It is impossible to know how much carbon 14 was in it at death and it is impossible to know if carbon 14 has always decayed at the same rate. If the earth had a canopy of water above the atmosphere, or a canopy of ice, that would have blocked out a lot of the radiation from the sun. This would have prevented most of the carbon 14 from even forming. Animals that lived before the flood would have lived in a world with much less carbon 14 to begin with.
There may have been none at all, but the amount would certainly be less than what we have today. If it does not entirely contradict them, we put it in a footnote. That is exactly correct. Here are some things to consider about carbon dating. When something of known age is dated: When something of unknown age is dated: That is not science! Taylor et al. Save-Soderbergh and I. So a date of 9, or 16, years is more likely to be less. Perhaps only 6, years old. Something that is years old for example.
But it is far from an exact Science. It is somewhat accurate back to a few thousand years, but carbon dating is not accurate past this. Thirty thousand years is about the limit. However, this does not mean that the earth is 30 thousand years old. It is much younger than that. Libbey knew that atmospheric carbon would reach equilibrium in 30, years. Because he assumed that the earth was millions of years old, he believed it was already at equilibrium. This would make the earth less than 10, years old! But there is more carbon in the atmosphere now than there was 4 thousand years ago. Carbon dating makes an animal living 4 thousand years ago when there was less atmospheric carbon appear to have lived thousands of years before it actually did.
What was the original amount of Carbon in the atmosphere? A great book on the flaws of dating methods is "Radioisotopes and the age of the earth" edited by Larry Vardiman, Andrew Snelling, Eugene F. Mary Schweitzer, associate professor of marine, earth, and atmospheric sciences at North Carolina State University, surprised scientists in when she reported finding soft tissue in dinosaur bones. She started a firestorm of controversy in and when she reported that she had sequenced proteins in the dinosaur bone. 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. Her report in confirmed the presence of collagen and other proteins that bacteria do not make.
His links and concessions are not bad. Schweitzer herself creators why these times are preserved when all the years say they should be noted. The half-life of C is great.
Unfortunately, humans are on the verge of messing things up. The slow, steady process of Carbon creation in the upper atmosphere has been dwarfed in the past centuries by humans spewing carbon from fossil fuels into the air. Since fossil fuels are millions of years old, they no longer contain any measurable amount of Carbon Thus, as millions of tons of Carbon are pushed into the atmosphere, the steady ratio of these two isotopes is being disrupted. In a study published last yearImperial College London physicist Heather Graven pointed out how these extra carbon emissions will skew radiocarbon dating. If nothing else, then, that should give all old-earth scientists something to think about.
According to this source: Since dinosaurs are thought to be over 65 million years old, the news is stunning. And more than some can tolerate. 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. Unwilling to challenge the data openly, they erased the report from public view without a word to the authors or even to the AOGS officers, until after an investigation. Here is a screen shot of the old program. Carbon is a radioactive isotope of carbon that is formed naturally in the atmosphere.
All plants and animals have a regular intake of carbon while they are alive. When an animal or plant dies, it no longer takes in carbon of any form.

coloribg C has a half-life of years. The maximum theoretical detection limit is aboutyears, but radiocarbon dating is only reliable up to 55, years with the best equipment. Older dates are considered to be tentative. If, as generally believed, dinosaurs have been extinct for 65 million years, there should not be one atom of Carbon left in their bones. The accuracy of carbon dates depends on flqws the ratio of Carbon to Carbon was the same in the past as it is today. There are two types of C dating technologies. The original one, counting Beta decay particles, is a multistep process and requires sample sizes of several grams.
Beta counting is prone to possible errors in each of the many phases. AMS uses a much smaller sample size, and actually counts the Carbon atoms as they are separated from the sample. The equipment accelerates streams of charged atomic particles to high velocities in order to sort and analyze them. Carbon dating of bone is one of the most difficult tasks in carbon dating, and requires the most care of any carbonaceous material. This is mainly due to the nature of bone, which is a very porous material. Certain parts of bone look like a sponge under the microscope.
Many dinosaur bones are hard as rock because the original material has been replaced with a silicon material such as quartz.
These are "mineralized" or "fossilized". We have found un-mineralized dinosaur bones. We then scrape the outer surface off to get rid of surface contamination, and date the inner remaining Carbon dating flaws dinosaurs coloring. One can date just the purified bioapatite, the total organics, or the collagen, flws a combination of these, as we did in several cases. This is a remarkable find because collagen, being a soft tissue present in most animals, is supposed Carbo decay in a few thousand years. Collagen is the main protein found in connective tissue of animals.
It can make up from 1 to 6 percent of muscle mass. Triceratops and Hadrosaur femur bones in excellent condition were discovered in Glendive Montana, and our group received permission to saw them in half and collect samples for Carbon testing. Dinosarus bones were tested by coloriny licensed lab for presence of collagen. Both bones did in fact contain some collagen. The best process Accelerator Mass Spectrometry was used to date them. Total organic carbon and dinosaur bioapatite was extracted and pretreated to remove potential contaminants, and concordant radiocarbon dates were obtained.
They were similar to radiocarbon dates for ice-age megafauna such as Siberian mammoths, saber tooth tigers of the Los Angeles LaBrea Tarpits, sloth dung, and giant bison. We usually prefer AMS dating because of its inherent superior accuracy, but use the conventional method when large samples are available in order to completely rule out contamination. This is recommended by a carbon-dating laboratory specialist. Robert Bennett, physicist and co-author, agree that "the AOGS-AGU assembly encourages presentation of reliable data even though the topic may be controversial. This is a very wise policy for the advacement of science and the education of people everywhere.
Thus, we encourage our colleagues to do their own carbon dating of dinosaur bones from museums and university fossil repositories around the world, as well as testing for C in scrapings from dinosaur bones as they are excavated. We are anxious to see their results presented, just as we have done. Also, we call on the news media and citizens everywhere to urge paleontologists, curators, university faculty, and government scientific agencies to encourage and support further testing for C content in dinosaur remains. Scientists need to know the actual chronology of the Earth and the age of the fossils.
