"A second reason why these ages are so widely accepted is that for scientific results to be published in research journals, they must be critically reviewed by other scientists who are experts in the same research area.
Yes JackH but one can not rule out 'bias'.
Here's another one,
There are two types of carbon 14
dating technologies. The original oldest one is a multistep process and requires sample sizes of several grams. The newer method of
"Accelerator Mass spectrometer" (
AMS technology) requires smaller sample sizes and is more
accurate.The earlier process is more prone to possibility of errors in each of the many phases. The latest technology (AMS) involves actually counting the carbon 14 atoms as they are separated from the sample. The equipment accelerates streams of charged atomic particles to high velocities in order to sort and analyze them. This newer method uses a much smaller sample size and can provide dates going back to maybe 100,000 at best. Generally
dates older than 70,000 are considered tentative ages.
Compare this with a dating scheme such as potassium argon dating which generally is considered accurate for 100,000 years and older.
We have no absolutely reliable dates of anything that is over 100,000 years old.
Sure there are
numerous claims that dinosaurs died out 65 million years ago due to radiometric dating of the KT geological boundary. In depth study of the methods and
assumptions used show that no method is anywhere near as
accurate or testable as tree ring counting and carbon 14 dating. All other dating methods have
serious problems and
gross assumptions must be made.
In addition
potassium argon dating has been shown by many to have serious problems.
If,as popularly
claimed, dinosaurs have been extinct for 65 million years, there should not be one molecule of carbon 14 left in their bones.
If as popularly believed most
limestone formations are 500 million years old, then there should be no carbon 14 present in them. Yet, when carbon-containing rocks or bones are tested they
always contain c14.
Both creationist and evolutionist have taken the one material that
cannot be accused of being contaminated and have used supposedly
500 million year to 3 billion year old diamonds to see if there is
any carbon 14 in them. Anything that old
should not have even one atom of carbon 14. Yet
both sides get the
same result and that is that
100 million year old diamonds do have carbon 14 in them. This is a
serious problem.
