And as reported at Science Direct, short-lived 14c is regularly found even in supposedly billion-year-old diamonds!
The assumption by evolutionary geophysicists proposes that the 14c in diamonds, coal, etc., must have come from neutron capture by carbon-13 or nitrogen-14.
And consider this from a peer-reviewed paper in a respected scientific journal, "at a constant 10°C (the approximate mean annual air temperature in Britain today) it will take between 0.2 and 0.7 Ma for levels of collagen to fall to 1% of their original concentration in an optimal burial environment." * Getting Graded: An expert on radiocarbon dating, long-time assistant professor at Loma Linda University, Dr. The teacher corrected a couple points and clarified a few others.
Paul Giem himself, graded the information presented below. He gave the original text (available here) a grade of A minus.
If contamination is really to blame for these results, then why does it appear in such supposedly old material as well as in delivers good entertainment as long as viewers overlook its bad science.
As reported in 2011 in the journal PLo S One, in an allegedly 80-million year old mosasaur.And if the 14c came from contamination, for example, one would not expect the contamination to so equally affect the bioapatite and the collagen.: Dinosaur bone showing 5pmc means that, because the 14c half-life is so brief, 5,730 years, if the radiocarbon is from contamination that occurred 6,000 years ago, a full five percent, i.e., 1/20th of the bone must have been replaced.(See below, 42 minutes into Paul Giem's 2013 presentation.) If the contamination occurred 12,000 years ago, 10% of the bone would have to be replaced; 18,000 years ago, 20%; if it occurred 24,000 years ago, 40% of the bone would have had to be replaced, and if (in the evolutionary perspective) a mere 30,000 years ago, 80% of the bone would have to be replace by a contamination process.Theoretical physicist Lawrence Krauss told RSR's Bob Enyart (rsr.org/krauss) that 14c in allegedly million-year-old specimens is an "anomaly." However, an anomaly is something that deviates from what is standard, normal, or expected.Because radiocarbon exists in significant quantities, far above the least count (margin of error) with our state-of-the-art AMS labs doing the tests, these results can !
