Closure temperature radiometric dating

There are a number of implausible assumptions involved in radiometric dating with respect to long time periods.

One key assumption is that the initial quantity of the parent element can be determined.

The Be nucleus (Beryllium-7) is an electron capturer with a half-life of about 53 days, turning into Lithium-7. While this half-life is way too short to be useful for radiometric dating, the effect of the chemical state is noticeable.

The reason is that, because the atomic number is only four, the 2s valence electrons are very close to the 1s electrons involved in capture.

This can happen due to one of three forces or "interactions": strong, electromagnetic, and weak, in order of decreasing strength.

As early as of 1673, John Ray, an English naturalist, reckoned with alternative that "im the primitive times and soon after the Creation the earth suffered far more concussions and mutations in its superficial part than afterward". Atoms consist of a heavy central core called the nucleus surrounded by clouds of lightweight particles (electrons), called electron shells.

The energy locked in the nucleus is enormous, but cannot be released easily.

The phenomenon we know as heat is simply the jiggling around of atoms and their components, so in principle a high enough temperature could cause the components of the core to break out.

However, the temperature required to do this is in in the millions of degrees, so this cannot be achieved by any natural process that we know about.

In some cases radioactive decay itself can be observed and measured in distant galaxies when a supernova explodes and ejects unstable nuclei.

  1. I get bored and there's ALMOST always something to do here... And gives me a chance to talk to pplz that i dont see everyday so there is always something we are talking bout that i dont already know this chat room is cool because it lets you meet new people all over the uk.
