Indeed, by doing almost 20 seconds of research on google (type in “variations in C14”, click on Google Scholar) the second link is this article from 1954: Carbon 13 in plants and the relationships between carbon 13 and carbon 14 variations in nature So, this issue has been known about for a long time. Then we compare the two and adjust the radiocarbon date to the known date. That’s less than 1% if you’re interested in that sort of thing. But this is already almost a thousand words and I’ve only done ONE! Long story short, scientists have always known that variations in C-14 concentration happen.
Do you honestly think that no one has done anything about it? By making thousands (if not millions) of these adjustments we get a very good idea of how old a piece of unknown material can be. The 2009 calibration set extends the ‘well calibrated range’ to 50,000 years using the varves in a Japanese lake. This is unlike the creationists which think it happened, but can’t be bothered to check.
(Aside, my dad doesn’t know how old I am, he usually misses by about two years, giving him an error of almost 5%.) Not only, is this not a ‘false assumption’. Oh and here’s a link to the Table of Contents for this set of creationist misconceptions.
Government officials had bought the chopsticks from a crafts shop during an operation last August in the city's Sheung Wan district, which is dotted with curio and antique vendors.
A stone artifact can be dated based on the way it looks and/or the way it was made.
Over many years of research chronologies of stone tools (and pottery) have been built, based on styles (called Seriation).
When plants take carbon atoms from the atmosphere during photosynthesis, they absorb a greater number of C ratio.
In this way, items of unknown age can be tested and an age determined to a reasonable degree of accuracy. More tomorrow where we explore the concept of isochron dating and how it neatly destroys most of the rest of these ‘issues’.For example, carbon most often has an atomic number of 12 (6 protons and 6 neutrons) and is labeled by scientists as C because it’s the isotope that decays over time and that scientists use in radiocarbon dating.Carbon atoms are constantly cycling through living and nonliving matter.I am not sure if I am allowed to do this, but I will try.I have been reading a lot lately, sparked by my reading in this Forum, trying to devour what I can about the Evolution Debates.
