Radioactive dating techniques are based on No cradit no money free sex chat

Evolutionists assume that the rate of cosmic bombardment of the atmosphere has always remained constant and that the rate of decay has remained constant.

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.

It's assumed that the clock was set to zero when the study material was formed.

This means the above calculations are only evolution speculation and NOT backed up by real science.

It is assumed that we are dealing with a closed system—no loss of either parent or daughter elements has occurred since the study material formed.

No scientist can guarantee that any sample can be considered a closed system unless it was isolated from its environment when it was formed.

Specimens would then look much older than they actually are.

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.While there is no proof that the rates were different in the past than they are today, there is also no proof that they were the same.Thus radioactive dating relies purely on assumptions.For more on this subject, see the video Bones in Stones i. Ogden III, "Annals of the New York Academy of Science," 288 (1977): 167-173. Outside the range of recorded history, calibration of the 14 clock is not possible.Some scientists argue that the magnetic field of the earth has declined over time.
