Potassium argon dating animation
Kelvin assumed that there was no source of "new" heat within the Earth.With the discovery of radioactive isotopes at the end of the previous century Kelvin's hypothesis was abandoned as it was shown that the decay of unstable radioactive isotopes was accompanied by the release of heat energy.My head is swimming from this morning's Curiosity press briefing here at the American Geophysical Union meeting in San Francisco.They talked about a lot of stuff but the really ground-breaking result is the fact that they have successfully used Curiosity's science instrument package to age-date their one drilled rock sample in two totally different ways.History records numerous attempts to determine the age of the Earth.Archbishop Usher of Ireland in 1664 argued that the Earth was "born" on October 26, 4004 BC at AM in the morning.It furnishes some good evidences that creationists often use.
First of all we must look at the initial condition of the system that is to be measured.It will also include the arguments for and against the accuracy of the dates for the age of the earth that are given by radioactive decay.This will include a discussion of other methods that have been used in dating the earth."How can creationists expect people to accept a young earth when science has proved through radiometric dating that the earth is billions of years old?" This article addresses that question, which represents the thinking of a large number of people today.
