Can radiocarbon dating date
See also, on this website, articles on the ages of the geologic periods (Ages), radiometric dating (Radiometric dating), the reliability of radiometric methods (Reliability), a "time machine" for studying the distant past (Time machine) and the "uniformitarian" assumption and how it relates to evolution and the age of the Earth (Uniformitarian).
I get that radiocarbon dating can account for discrepancies in the atmospheric concentration of carbon-14/carbon-12 through the Carbon curve wherein other dating methods were able to verify the accuracy of carbon dating.
The half-life itself would have been determined by studying the rate of decay in samples over a set amount of time (hours, days, weeks, etc.) and then projecting that backwards using the formula derived from the experiment.
Radiocarbon dating has been studied at great length over the past few decades, and its strengths and weaknesses are very well understood at this point in time.For instance, creationist Walt Brown has pointed out inconsistencies in some radiocarbon dates of mammoths -- one part was dated to 40,000 years, another to 26,000 years (and wood surrounding it to 10,000 years), and yet another to between 15,000 and 21,000 years before the present epoch [Brown2001].However, in the scientific results mentioned by Brown, the dates come from different mammoth specimens.However, Wikipedia notes that this carbon curve has only validated radiocarbon dating back 8,000 years.
How can we use this method to speculate on dates going back 100,000 years?Since it is chemically indistinguishable from the stable isotopes of carbon (carbon-12 and carbon-13), radiocarbon is taken by plants during photosynthesis and then ingested by animals regularly throughout their lifetimes.
