Most accurate radiometric dating Absolutely free whore teen cams
Whitelaw (1968), who believed that C-14 could date no farther back than 5000 years. Walt Brown (2008), has presented recent data showing that C-14 dating becomes unreliable after about 3,500 years.
The bottom line is that C-14 dating is clearly useless for dating so-called prehistoric life forms.
Scientists place great faith in this dating method, and yet more than 50% of radiocarbon dates from geological and archaeological samples of northeastern North America have been deemed unacceptable after investigation.
The following striking examples are just the tip of the iceberg: Another thing you may not have known, is that Carbon dating was not invented until 1949! Why were they teaching the earth is billions of years old 160 years ago?
d) Even if the rate of decay is constant, without knowledge of the exact ratio of carbon-12 to carbon-14in the initial sample, the dating technique is subject to question.
It's assumed that the clock was set to zero when the study material was formed.
