Most young earth creationists reject all of these points.
As a scientific skeptics, we ask ourselves: is this really the case?
This serves as strong evidence for the reliability of radiometric dating methods. These isotopes differ in the number of neutrons they have in their nuclei.
There are many different kinds of radiometric dating and not all conclusions we will reach can be extrapolated to all methods used.
Also, different radiometric dating techniques independently converges with each other and with other dating techniques such as dendrochronology, layers in sediment, growth rings on corals, rhythmic layering of ice in glaciers, magnetostratigraphy, fission tracks and many other methods. There exists different versions, or isotopes of many elements.
A very common claim of young earth creationists in trying to reject the evidence for an old earth is to loudly proclaim that radiometric dating methods “makes assumptions” and that these “assumptions” are somehow fatally flawed or not supported by evidence.
These claims generally land in three different categories: (1) radiometric dating assumes that initial conditions (concentrations of mother and daughter nuclei) are known, (2) radiometric dating assumes that rocks are closed systems and (3) radiometric dating assumes that decay rates are constant.
While certainly entertaining (at least in retrospective), I think that this kind of ‘information’ does more harm than good. I will try to explain the basic facts about radiation and show why the most common misunderstandings and myths are wrong.
My task is not to belittle the dangers of radiation, but rather help you understand it a little bit.
Advocates of the Carbon dating method have turned to "Dendrochronology" (a.k.a.
tree-ring dating) to calibrate their timescale (that is, to adjust it to compensate for the C-12 to C-14 ratio fluctuations).
Mara Mulrooney, believe that intepretation of the island's history is wrong.
Mulrooney studied 300 radiocarbon dates from Rapa Nui and found that people continued to use the interior of the island to cultivate crops such as sweet potatoes up until European contact.
Previously it had been believed that these areas had been abandoned when the island chiefdom supposedly collapsed.
