Besides the aforementioned items, the amount of cosmic radiation in the past, and in particular the amount reaching the atmosphere, may have been dramatically different.

If one were to believe the Bible, the earth was surrounded by a layer of water vapor between Creation and the Flood.

As the magnetic field decreases, more cosmic radiation penetrates the earth’s atmosphere and this causes a slow long-term increase in Carbon-14 production.

In high school biology courses they often teach about the inevitable failures of closed systems by taking an aquarium and placing snails, plants and a bowl of water inside; then sealing the aquarium so that no air may get in or out.

The idea is that snails produce carbon dioxide which is utilized by the plants, the plants produce oxygen which utilized by the snails. Of course, it doesn’t take long before the experiment fails in death for all those in the aquarium.

He claimed that it was capable of dating animal, plant and human remains of fairly “recent’ origin. As they say on Star Trek, we are all carbon based units.

Laboratory research has shown that the radioactive decay of Carbon-14 occurs in a half-life of 5,73040 years through beta decay that causes the Carbon-14 to revert back to Nitrogen-14.

Carbon-14 decays to a zero amount in 250,000 supposed years after its production.

It is incapable of yielding dates in the millions of years.

The theoretical limit of the usefulness of Carbon-14 dating would only be 50,000 years.

This would be the amount of time it would take for nine half-lives, and after that there would not be enough left to measure accurately.

They all start with similar flaws, but Carbon-14 has more than the rest.
