What is the purpose of radioactive dating
It is founded on unprovable assumptions such as 1) there has been no contamination and 2) the decay rate has remained constant.
By dating rocks of known ages which give highly inflated ages, geologists have shown this method can’t give reliable absolute ages.
Yet few people know how radiometric dating works or bother to ask what assumptions drive the conclusions. This figure wasn’t established by radiometric dating of the earth itself. Radiohalos shouldn’t exist, according to conventional wisdom!
Though they are very tiny, polonium radiohalos have a huge message that cannot be ignored.
After all, textbooks, media, and museums glibly present ages of millions of years as fact.Many geologists claim that radiometric “clocks” show rocks to be millions of years old.However, to read any clock accurately we must know where the clock was set at the beginning.Therefore the amount of argon formed provides a direct measurement of the amount of potassium-40 present in the specimen when it was originally formed.Because argon is an inert gas, it is not possible that it might have been in the mineral when it was first formed from molten magma.
Potassium-Argon dating: The element potassium (symbol K) has three nuclides, K39, K40, and K41. K40 can decay in two different ways: it can break down into either calcium or argon.
