Carbon-14 is only used to map dates up to 50,000 years old.
Dang...I just ordered 5-billion candles for a cake...
This is not a new discovery. It has been known for a long time. Secular scientists are doing everything they can to deny the Creation account in Genesis. Problem is....the facts keep getting in the way of their narrative.
Henry Morris brought this up years ago in his first book. Don’t tell sunkinciv, he’ll be devastated.
Getting tired of people abusing the word history.
This comes up every few years like sterile medical maggots or adulterated chinese foodstuffs. Give it a rest already.
It’s “settled science”, ..... until it isn’t.
Nineteen years ago, oh dear. What inaccuracy!
My wife has put me on a Carbon-14 free diet so I can’t be dated.
But, by all means, maintain your faith in the “settled science” behind global warming...
Actually carbon-14 decays to nitrogen-14, when a negatively-charged beta particle is emitted and a neutron is converted into a proton.
You’ve probably heard of this before...but just in case...
.
Time itself began just over 6000 years ago.
People are so gullible.
I think the author has a different definition of the word "significant" than I do. He's talking about measurements that are up to 20 years off... hardly significant, considering that the range of C14 dating is 50,000 years or even longer with sophisticated techniques. An error of 20/50,000, or 0.04%, is hardly "significant." In the scientific world, we would call such a small error a component of "background noise."
background radiation is not constant geographically so production of carbon 14 is inconsistent too.
The issue is the calibration you use during each different period of time.
It works sort of like your car speedometer. There is always a little error. But how much? At different speeds the % of error is different. And that error changes depending on rolling friction, humidity, tear wear, etc.
The same with carbon14 dating. Living things get their carbon14 from air and stop doing that when they die. Carbon14 is radioactive and at death, “boils off” at a known rate, reducing its concentration. We can measure that.
The air concentration of carbon14 has always varied. Also, the S hemisphere has more water and thus less carbon14. Sunspots, volcanic eruptions, etc. change that concentration.
So, we can calibrate pretty accurately by counting tree rings and pinning that to the carbon14 concentration, pretty crispy. We’ve done that with trees 8,000 years old.
Beyond that, it’s guess work beyond about 95% accuracy.
Carbon 14 is strictly short term dating. Lots of other isotopes for longterm results.
C-14 dating is much more accurate than 50 years ago.
This has been pointed out for scores of years
It’s a pretty good technique, I think, but not if you’re looking for pinpoint accuracy.
This is not new information. My father worked on the calibration of carbon14 dating back in the 60’s, at the National Bureau of Standards. They were aware of the need to include the proportions of C14 vs C12 in the atmosphere at the time of the of the formation of the organic substance, in order to get the most precise dating. That is why, among other things, the dates are always given as a range e.g. 1000 to 2000 before the present.
