Usually the scientists doing the measurements are assuming they know, for example, how much C14, which is radioactive carbon, was in the organism when it died (C14 dating is used to determine the age of things that were once alive.) Where did that radioactive carbon come from?We will now look at several arguments, which may or may not be supported by Dr. I will also present a couple of arguments indicating that the earth is much older than a few thousand years.The time that it takes for half of a sample to decay is known as the half life of the isotope.Some isotopes have half lives longer than the present age of the universe, but they are still subject to the same laws of quantum physics and will eventually decay, even if doing so at a time when all remaining atoms in the universe are separated by astronomical distances.
It was the 'brave new world', 'the new frontier', and every other clich Zˇ one can think of - so if one word could be used to describe it, it would be 'excitement'.
It was customary to then prevail on some well known physics or chemistry professor to supply the technical expertise, and he in turn would select some unsuspecting graduate student to build it.
Graduate students were among the few at that time who could even spell the magic words 'nucleonics', 'electronics' and 'vacuum lines' born of hush-hush wartime technologies.
Eat one of those and your tummy will curl right up!
Seriously speaking, a favorite attack on radiometric dating involves dangling "horror stories" about gross errors before the reader, thus giving the impression that radiometric dating is totally unreliable.
