The first is that atoms have always decayed at the same rate.
Let us critically examine each of these claims and see if they hold up against the science.
While doing so, we will have to learn about how radiometric dating works.
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.
by Tas Walker A geologist works out the relative age of a rock by carefully studying where the rock is found in the field."How can creationists expect people to accept a young earth when science has proved through radiometric dating that the earth is billions of years old?" This article addresses that question, which represents the thinking of a large number of people today.These were then eroded and Sedimentary Rocks B were deposited. At their request, physicist Dr Jim Mason, of CMI Canada, reviewed the material from the meeting and his response was published on 2 April 2015 (see Response to Geochronology: Understanding the Uncertainties, a presentation by Dr Justin Payne).There are many different kinds of radiometric dating and not all conclusions we will reach can be extrapolated to all methods used.
