Radiometric dating applied metamorphic rocks irina 36 yo dating

The only dating methods discussed (over and over) by evolution-believing scientists and the mass media are those that supposedly "prove" that the earth is billions of years old.One of the most popular of these is known as radiometric dating. can be In other words, something in the past caused a significant amount of helium to build up inside these zircons (such as from a rapid decay episode of uranium), yet, in spite of the fact that helium has been observed to leak out readily from these zircons, it has not done so: simply because it hasn't had enough time to do so -- suggesting that the zircons themselves are only a few thousand years old."There is evidence to show ...

(the same) size, then it can be safely assumed that the half-life of that decay is a constant.

If, on the other hand, it is found that the radii vary, then this is proof that the half-life of that decay is not constant.

This was first shown by Joly and Henderson who conducted most of the early studies on pleochroic haloes. We have solid evidence that radioactive decay rates cannot have been constant.

This proves that the half-lives of the uranium and thorium radioactive decays vary ... any age determination using this method of dating will be inaccurate because it is based on an invalid assumption." " ... For example, discordant dates have been obtained on the same rocks by ...

can we be sure the U and Th have always decayed at the same rates we measure today? (various) Given ample evidence observable in the present that decay rates have not been constant throughout the supposed deep time, it is not reasonable to assume they have been uniform through unobservable eons.
