The earth has been determined by radiometric dating to be Free sex cam girl online
The key questions then are: Has the atmospheric ratio of carbon-14 to carbon-12 changed in the past, and if so, why and how much?
The assumption usually made, but rarely acknowledged, is that the ratio of carbon-14 to carbon-12 in the atmosphere before the industrial revolution has always been the sameabout one in a trillion.
However, before accepting any radiocarbon date, one should know how the technique works, its limitations, and its assumptions.
Radiocarbon ages less than 3,500 years old are probably accurate.When a living thing dies, its radiocarbon loss (decay) is no longer balanced by intake, so its radiocarbon steadily decreases with a half-life of 5,730 years.If we knew the amount of carbon-14 in an organism when it died, we could attempt to date the time of death.Until recent years, scientists who believe in creation haven't had the necessary resources to explore radiometric dating in detail.
A 10 gram sample of U-238Now that has changed, and some important discoveries are being made.
The samples were from a mile below the earth, which, according to inflated evolutionary years, were 1.5 billion years old.
