How does potassium 40 dating work

If you asked the same question of an educated European in AD 1900 you would have received a quite different answer.

A further example from a lava flow off the coast of Hawaii shows similar discrepancies.If dated with the carbon-14 method, the flow appears to be less than 17,000 years old, but dating with the potassium argon method gives dates of 160,000 to 43 million years.We could put forward the following counter arguments to the constancy of these assumptions: a) The constancy of cosmic ray bombardment might be questioned.The current high rate of entry might be a consequence of a disturbed post-Flood environment that altered the .They will argue that the clock was not reset if the age is too old, or that isotopes were selectively removed if the age turns out to be too young.

In the study on the Hawaii lava flow cited above, it was argued that entrapment of excessive amounts of argon gas had made the samples appear older than they were.

If, in the year AD 1600, you had asked an educated European how old the planet Earth was and to recount its history he would have said that it was about 6000 years old and that its ancient history was given by the biblical account in Genesis.Some scientists argue that the magnetic field of the earth has declined over time.
