Is Carbon Dating Reliable? | informativonossobairro.com

Robert Whitelaw has done a very good job illustrating this theory using about 30, dates published in Radio Carbon over the last 40 years. The guy, Pat Patterson, went on to demonstrate widespread lead contamination in the environment, which eventually lead to regulations in the 's limiting the use of lead. Fairbanks, a member of the Lamont-Doherty group, said that if the dates of glaciation were determined using the uranium-thorium method, the delay - and the puzzle - disappeared. Talk of circular reasoning!!!! Errors in procedure can also lead to errors in the results. The scientists who were trying to build the chronology found the tree rings so ambiguous that they could not decide which rings matched which using the bristlecone pine.

Tried talking to a friend today about this. He's an applied physics engineer for NASA. He avoided it like the plague! Just said. Aah, nothing new. . I'm like 1.6 million mph ? Twice the norm? Nothing new? he just shrugged took another drink off his bloody Mary. This is the guy designing the new asteroid discovery and tracking devise. With 10 times the power we have now. (All declassified Or I wouldn't mention it. he finally just said. We don't know anything it's all just guesses, trail and error , etc. But it sure is hot today. Be safe all.
