Forget your miffed dismissal of the current thought on the history of the universe. But the ones above give you a general idea. Now take that to the next step, to effect such a change you would need to effect the Weak Force directly within an atom or group of atoms. Coal, oil, and natural gas are supposed to be millions of years old; yet creationists say that some of them contain measurable amounts of C-14, enough to give them C-14 ages in the tens of thousands of years. Radiocarbon dating cannot be used for older specimens, because so little carbon-14 remains in samples that it cannot be reliably measured. Bailey Updated 15 December 2018 c 2018 Introduction Radiocarbon dating, which is also known as carbon-14 dating, is one widely used radiometric dating scheme to determine dates of ancient artifacts.
What many do not realize is that carbon dating is not used to date dinosaurs. How can it have different elongations of the constants towards different bodies? The results can be as much as 150 million years different from each other! Astrophysics is not my discipline, to say the least, but even though a lot of what we look at it very large, many important things we observe are all still driven by physics. The guy we have to credit is Willard Libby who discovered carbon dating in the 1940s, got the Nobel Prize for it actually. Plants obtain all their carbon atoms from the atmosphere. Because of this, radiocarbon chemists are continually developing new methods to more effectively clean materials. They have their work cut out for them, however, because radiocarbon C-14 dating is one of the most reliable of all the radiometric dating methods. They assume dinosaurs lived millions of years ago instead of thousands of years ago like the bible says.
Younger objects can easily be dated, because they still emit plenty of beta radiation, enough to be measured after the background radiation has been subtracted out of the total beta radiation. More precisely, we can put limits on how much it could have changed - and it's pretty damn small. Unfortunately the ratio of carbon-12 to carbon-14 has yet to reach a state of equilibrium in our atmosphere; there is more carbon-14 in the air today than there was thousands of years ago. This does make the assumption that the production of 14C and incorporation into the food chain is the same now as it was thousands and thousands of years ago. But 14C is not just used in dating. 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 results stated that the snails had died 27,000 years ago. Consequently organisms living there dated by C14 give ages much older than their true age. The ratio of radiocarbon to stable carbon atoms in the atmosphere has varied in the past. So why is it that if the date doesn't fit the theory, they change the facts? Carbon dating is used to work out the age of organic material — in effect, any living thing. This ratio is the same for all organisms across the globe at a given time due to the mixing of the atmosphere mentioned above. If the measurements prove useful, and allow us to manipulate matter for our own good, so much the better. Creationist criticisms of radiocarbon dating As mentioned above, young-earth creationist writers have cited various anomalies and potential difficulties with radiocarbon dating, and have used these examples to justify their conclusion that the entire scheme is flawed and unreliable.
Answer: C-14 dates show that the last glaciation started to subside around twenty thousand years ago. If we're a bit depleted in nitrogen-14, then we know it's become carbon-14. But it is far from an exact Science. All we can do is measure things. They then use potassium argon, or other methods, and date the fossils again.

But, as is clear even from the very brief discussion in the previous paragraph, radiocarbon dating can say nothing one way or the other about whether the Earth is many millions of years old, since such dates are far beyond this method's range of resolution. In the 19th and early 20th century incredibly patient and careful archaeologists would link pottery and stone tools in different geographical areas by similarities in shape and patterning. We detect light from a distant galaxy cluster carrying the absorption line at 656. This article is reproduced with permission from the magazine. You see, if you mess with the weak force, you automatically then have to mess with the electromagnetic force, since they're interrelated electroweak unification. This assumption but it's assumed to be a fairly reasonable and accurate way to do it.
The more accurate carbon clock should yield better dates for any overlap of humans and Neanderthals, as well as for determining how climate changes influenced the extinction of Neanderthals. This man-made fluctuation wasn't a natural occurrence, but it demonstrates the fact that fluctuation is possible and that a period of natural upheaval upon the earth could greatly affect the ratio. Archaeologists vehemently disagree over the effects changing climate and competition from recently arriving humans had on the Neanderthals' demise. . Because of this relatively short half-life, radiocarbon is useful for dating items of a relatively recent vintage, as far back as roughly 50,000 years before the present epoch. A bit in one way, the rate of fusion goes through the roof and the Sun blows itself apart. But, while space is largely empty, not all of it is.
The carbon that's in carbon dating is carbon that's been newly made. For instance, the amount varies according to how many cosmic rays reach Earth. The technique hinges on carbon-14, a radioactive isotope of the element that, unlike other more stable forms of carbon, decays away at a steady rate. For one thing, there are a very small number of blue shifted entities entities that are coming toward us instead of going away that should be a problem for such a hypothesis. We see objects either ahead if faster c or behind if slower c where they should be after accounting for the constant speed of light. As it stands, the thesis is vulnerable to being shown, in some fashion of this sort, to be a privileged frame of reference argument.
