* Carbon-14 is Everywhere It Shouldn't Be: Carbon-14 doesn't lie. And it can't be an anomaly, because it's not here and there but its everywhere it shouldn't be. It's so unstable that a solid ball of 14c the size of the Earth would all decay into nitrogen in less than a million years. So if plenty of 14c, in quantities far above a modern lab's margin of processing and measurement errors, is found everywhere and in specimens allegedly millions or billions of years old, like dinosaur soft tissue itself (bflist.rsr.org) that is powerful hard scientific evidence that these are not millions but only thousands of years old. For a typical sample, all of its original 14c atoms would radioactively decay in far less than 100,000 years. Theoretically, contamination, measurement error, or neutron capture could explain apparent radiocarbon in allegedly older samples. On these, see below, but briefly for example, while modern bacteria can infest and bore its way through a dinosaur bone, in 2017 Nature reported an isotope study that found that such bacteria does not affect the bone's radiocarbon content (and date) because the carbon the bacteria feeds on does not come from the atmosphere but comes exclusively from the bone itself! Thus radiocarbon dating gives a relatively young upper age for specimens regardless of the primary contamination concern, namely, bacteria.
* 14c Factoids: For a better "gut feel" for the topic...
- Our atmosphere has one carbon-14 atom for every one trillion carbon atoms.
- 21 pounds of 14c are produced in the atmosphere every year!
- Unstable radiocarbon decays with a half-life of 5,730 years. (half-life symbol = t1/2)
- A solid ball of 14c the size of the Earth would all decay into nitrogen in less than a million years.
- A gram of carbon has about 50 sextillion carbon atoms. (50,000,000,000,000,000,000,000)
- RSR co-host Fred has about 10 octillion total atoms in his body. (one octillion of carbon)
- Fred, a big guy, carries around about 50 billion radiocarbon atoms! (50,000,000,000)
- Fred's body experiences about 2,500 decays of 14c to nitrogen every second.
- One 14c atom in a trillion carbon atoms is referred to as 100 percent modern carbon. (100 pMC)
- Likewise, 100 14c atoms in a 100 trillion is referred to as 100 percent modern carbon.
- So 50 14c atoms in a 100 trillion carbon atoms is referred to as 50 percent modern carbon. (50 pMC)
- Fifty percent modern carbon is interpreted as 5,730 years before present. (about 6,000 years BP)
- The best AMS labs accurately count 14c atoms to even 0.001 of a percent modern carbon. (1000th pMC)
- Published lab measurements show processing introduces 1/10th to 3/10ths of a percent contamination. (~0.2 pMC)
- So lab contamination adds one 14c atom to 250 in 500 trillion carbon atoms. (Yielding 251 of 500 trillion or 50.2 pMC.)
- 14c "ages" get progressively significantly inflated as with bones from 873 AD dated to 200 years earlier.
- Pompeii, destroyed in 79 AD, was expected to give appropriate ages but gave 2400 to 5800 years BP.
- Old 14c "dates" are progressively too old and there's far too much C-14 in diamonds, etc., to be contamination!
Anything even just one million years old should have no "modern" carbon (once the well studied background contamination is subtracted). However, scientists are consistently finding significant amounts of 14c everywhere it shouldn't be including the 2019 report in eLife on a Centrosaurus. In 2011 the journal PLoS One reported plenty of modern carbon in an allegedly 80-million year old mosasaur bone. The journal Radiocarbon has reported 14c in natural gas, coal, oil and other petroleum products. Other careful studies report radiocarbon in limestone (from the Mesozoic layer), fossilized wood, coal, marble, deep groundwater, geological graphite, and in many dinosaur bones including the ten described below and the seven described in 2015 in the Radiocarbon in Dinosaur and Other Fossils paper by paleobiochemist Dr. Brian Thomas and his co-author Vance Nelson. And as reported at ScienceDirect, 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. 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 no longer be called anomalies! The Radiocarbon field itself now widely acknowledges, and tries almost desperately to discount, that specimens supposedly millions and billions of years old will yield maximum carbon-14 ages of only thousands of years!
* Carbon 14 in Dinosaurs at Singapore's American Geophysical Conference: On how to date a dinosaur, Real Science Radio's Bob Enyart interviews Hugh Miller, a member of the international scientific team that presented at the 2012 AGU geophysical conference in Singapore, the carbon dating results from five respected laboratories around the world of bones from ten dinosaurs (from the Gobi Desert in China, from Europe, Alaska, Texas, and Montana). 14c lasts only thousands of years, not millions. Yet each of these dinosaurs had plenty of radiocarbon (as expected in that virtually every relevant peer-reviewed paper on the topic confirms the presence of endogenous soft tissue in fossils; see DinosaurSoftTissue.com). With the scientific breakthroughs and discoveries coming in daily, this is a great time to be alive!
* Update: At creation.com/c14-dinos, see the great summary of this presentation from Carl Wieland, president of Creation Ministries International. 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. Paul Giem himself, graded the information presented below. (You can hear that interview with Dr. Giem here). The teacher corrected a couple points and clarified a few others. He gave the original text (available here) a grade of A minus. Of course we're hoping that now that we've corrected the material below, that this is solid A+ work!
* Six Problems with the Contamination Explanation: (See the 6th point below for why collagen itself cannot be contaminated with modern carbon and for the Nature 2017 paper explaining that microbes like cyanobacteria in fossils get their carbon not from the atmosphere but from their bone substrate, meaning that they cannot supply a younger date than a dinosaur fossil, because they date the same as that fossil!) Both mathematical analysis of the data, and the nature of some of the specimens, indicate that contamination does not solve the radiocarbon problem for old-earth geologists.
First: While dinosaur bones, coal, and other specimens could easily be contaminated, diamonds, the hardest naturally occurring substance in the world are naturally resistant to contamination. Thus, when significant quantities of 14c are found, for example, in coal and dinosaur bones, as well as in diamonds, the least contamination-resistant 14c-rich specimens provide a constraint on the likelihood of contamination as a primary source for the modern carbon in other similarly-dated specimens. Thus the radiocarbon content of diamonds is all the more compelling and important, and especially when the specimens are mined from a quarter-of-a-mile below the surface, insulated from our 14c-bearing atmosphere. Contamination is not only far more unlikely within deep-mined and unbroken diamonds, but because of the unique physical composition of diamonds, various kinds of contamination could be more readily detectable.
Second: Just as forensic accountants can often determine when a criminal business has cooked its books merely by doing a Benford statistical analysis of the numbers, so too mathematicians have demonstrated that statistical analysis can indicate whether scientific data is likely a result of measurement errors. So evolutionists typically claim that all this 14c results from contamination, but statistical analysis indicates that when plotting erroneous dates (as from contamination), the data should fit a normal curve. However, it does not. As documented by Rick Sanders in A Case of "Missing" Decay in CRSQ, the distribution provides significant evidence that the radiometric ages do not result from contamination errors. Regarding the results from the ten dinosaurs dated (as above), of course, bacteria do not make collagen. And if the 14c came from contamination, for example, one would not expect the contamination to so equally affect the bioapatite and the collagen.
Third: The above paper indicates that where sampled, the ground area has decreasing 14c with distance from the dinosaur bone, indicating that modern carbon is leaching out of the bone (which is not problematic), but, most significantly, not seeping into the bone.
Fourth: Dinosaur bone showing 5pmc means that five percent of the carbon in the bone needs to be replaced with modern carbon, which high level of contamination would very possibly be detectable.
Fifth: 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. Thus, where researchers find both soft tissue and 14c, especially in small bones as with the mosasaur, the claim that the biological tissue is dinosaurian and is not contamination works exactly against the claim that the 14c is from contamination.
Sixth: The inventor of the radiocarbon dating method, Dr. Walter Libby, stated in the journal Science, "There is no known natural mechanism by which collagen may be altered to yield a false age." To clarify (and still, as of 2021) there is still no known mechanism to contaminate collagen with modern carbon formed in the atmosphere. Further, a 2017 paper in Nature, Carbon fixation from mineral carbonates, confirms that cynobacteria in fossils get "virtually all" of their carbon from the bone substrate they are feeding on! Therefore they cannot "contaminate" the 14c results because they will carbon "date" the same as the bone itself, for their percentage of modern carbon is identical to that of the bone. (Further, there is a pretreatment process of repeated washes of acid/alkali/acid to remove any outer humic acid and debris.) Therefore creationists have been correct to dispute Mary Schweitzer, Lindgren, et al., as they've tried to explain away as microbial contamination the "modern" carbon in an endogenous biomaterial Mosasaur bone. Etc. (See also this post from a committed evolutionist in a battle royale with our old friend rsr.org/david-willis at the Evolution Fairytale forum run by RSR host Fred Williams.) Regarding Libby's "no known natural mechanism" way of contaminating collagen, here's our RSR explanation of why this is. If a specimen is purified to 95% collagen, or 98%, or 99%, etc., then approximately the same percent of the carbon in the fossil sample will be endogenous (i.e., original to the living animal). Why? Because in collagen, new carbon atoms cannot replace original carbon atoms in the tightly-woven scaffolding molecule. As a result of decomposition, to the extent that original carbon atoms were decaying into a gas (nitrogen) and thereby falling out of the scaffolding, then to that extent you would no longer have collagen; rather, to that extent you would have humic acid. Decomposing collagen cannot be "repaired" by free carbon atoms happening upon the decomposition. Rather, the collagen must be manufactured within a living animal (with its constituent carbon atoms) into a "super-super-coil... interdigitated with its neighboring microfibrils... so well ordered as to be crystalline." Further, bacteria do not make collagen, which eliminates another possible source of contamination. So if a researcher can verify that he has a sample that has been purified to 99% collagen, for example, then he can be sure that all the carbon in that 99% of the sample is original.
2021 Update - Technology vs Old-Earthers: A form of electron microscopy called ptychography captures high resolution images of individual atoms (see right) at 100 million times magnification! If one day scientists using advanced technology can confirm a 100% pure collagen sample, that will end the claim that its short-lived carbon-14 might be contamination!
* Six Problems with the Neutron Capture Explanation
First: Unexpected C14 is found in specimens worldwide, yet 14c production (in the ground as compared to in the atmosphere) requires a lot of nearby radioactivity to produce appreciable amounts of 14c by neutron capture. However, terrestrial radioactivity is concentrated, with the vast majority of it occurring in the continental crust. (On RSR Lawrence Krauss confirmed this well-documented observation.) Ninety percent of Earth's radioactivity is in 1/3rd of 1% of it's mass.
Second: Radioactivity is relatively scarce even in the continental crust, at least as documented by this U.S.G.S. report for enormous swaths of land.
Third: Presented at the 2012 AGU Singapore conference, there was less than 20 parts per million of uranium and thorium in the dinosaur bones that contained large quantities of modern carbon, so much that it registered mid-range in the AMS (accelerator mass spectrometry) capabilities. Also, Uranium mines where the uranium content is 18% yield carbon specimens which have 1% 14c.
