On a side note, did you know that there is a huge assumption made about the age of the earth? It is not determined from terrestrial rocks, but from meteorites! The assumption is that everything formed at the same time, and meteorites are purer than the rocks on our own world. Old son, that's circular reasoning.
Back to the main topic now. In Part 3, the Potassium-Argon dating method is examined. Although considered to be the most reliable, this method is so loaded with assumptions, it is actually unreliable and unscientific. Once again, a proper interpretation of the evidence points to a young planet.
Radioactive dating methods—many of which are quite elaborate—have numerous physical condition requirements that cannot realistically remain unaffected over millions and perhaps billions of years. Since the potassium-argon dating methods clearly appear to be unreliable, why should any rational person trust them to provide accurate dates for rocks?To finish reading, click on "The Noble Clock: Radioactive Dating, Part 3"
In the early 1950s, scientists established theories for using the decay of radioactive potassium (40K) to argon (40Ar) as a clock for dating certain types of rocks. Called “noble” because it rarely bonds with other elements, argon (Ar) is one of the six noble gases. The others include helium (He), neon (Ne), krypton (Kr), xenon (Xe), and radon (Rn).
