Explain carbon 14 radioactive dating sex dating in pineville kentucky
Here are some specific results along this line; many more could be cited.These were taken from a conference in 2012Fossils, coal, oil, natural gas, limestone, marble, and graphite from every Flood-related rock layer—and even some pre-Flood deposits—have all contained measurable quantities of radiocarbon.The half-life of C14 is 5730 years, although there are subtleties about how C14 ages are actually computed.That means that in 5730 years, half of the C14 will decay to nitrogen 14.If decay rates were faster in the past, then even the C14 dates could be too old.Carbon 14 is an isotope of carbon with two extra neutrons in the nucleus. The rate at which this happens varies to some extent.
When an organism dies, control over the configuration of the amino acids ceases, and the ratio of D to L moves from a value near 0 towards an equilibrium value near 1, a process called racemization.
Thus, measuring the ratio of D to L in a sample enables one to estimate how long ago the specimen died.
This dating method is considered to be accurate for ages up to several hundred thousand years.
Here are more quotations from the Science article referenced above:, Schweitzer, her postdoc Elena Schroeter, and colleagues report that they did a complete makeover of their 2009 experiment to rule out any possible contamination. Schroeter even went so far as to break down the mass spectrometer piece by piece, soak the whole thing in methanol to remove any possible contaminants, and reassemble the machine. Just how those collagen sequences survived for tens of millions of years is not clear.
“About the only thing that is the same [as the 2009 experiments] is the dinosaur,” Schweitzer says. Meanwhile, Schweitzer’s team is going beyond collagen.
