If I am using that word correctly, then in what sense does an extinct element "occur on Earth"? The matter that makes the earth came from some supernova(s) in the distant past.The matter ejected collected to form the sun and planets of our solar system.
Wiens has a Ph D in Physics, with a minor in Geology.
His Ph D thesis was on isotope ratios in meteorites, including surface exposure dating.
Radiometric dating is one of the most important subject matters concerning the creation vs. It is one of the primary focal points that evolutionists use to essential backup most of their claims for a long earth time frame (4.6 billion years old).
Unfortunately, the subject is vaguely understood well enough by most people.
Each element may exist in one of many different isotopes, which means that it contains a different number of neutrons (neutral particles) in its nucleus, a specific isotope of a particular element is called a nuclide.
Over time, some atoms that have unstable nuclides will transform into a different nuclide.
A committee of the ‘Measure of Geologic Time’ formed by the national research council with Alfred C.
Lane geologic professor as the chair, and began to establish the radio metric dating method.
Is there some information on time or age, embedded in Nature and its nuclei, be it on cosmological, galactic, geologic, prehistorical or historical time scales ? Our research, extending to several disciplines, is devoted to these questions.
Literature and Links : stable nuclides which constitute matter as we know it, ourselves, our computer chips, the planets around us, have been synthesized in the stars of our Galaxy.
At the time of the supernova all sorts of isotopes were created.
