The rate at which the regeneration takes place has gone virtually unchanged for centuries; a feature which depends on the flux of particles bombarding the earth, and the strength of the magnetic field capable of diverting them.This magnetic shield, and consequently the particle flux, has slowly changed over time, and the quantity of carbon 14 formed on Earth changes with Dr Carl Wieland An attempt to explain this very important method of dating and the way in which, when fully understood, it supports a ‘short’ timescale.In fact, the whole method is a giant ‘clock’ which seems to put a very young upper limit on the age of the atmosphere.The radioactive atom is absorbed by plants and living matter in the same way as its non-radioactive isotope ; in every thousand billion (ten to the power of twelve) atoms of carbon 12, there will be on average one atom of carbon 14.This tiny ratio exists in all molecules involving carbon atms, including all living matter.Because Libby believed that the Earth was millions of years old, he assumed that there had been plenty of time for the system to be in C was entering the atmosphere as fast as it was leaving—calculations show that this should take place in about 30,000 years, and of course the Earth was much older than that, said the geologists.

The carbon 14 found in nature is constantly being regenerated by cosmic rays hitting the atmosphere.

This is why carbon 14, along with potassium 40, accounts for almost all the natural radioactivity of our body.

When a living organism dies, the radioactive carbon is no longer absorbed, and the ratio of carbon 14 present begins to decrease.

Obviously this only works for things which once contained carbon—it can’t be used to date rocks and minerals, for example. We obviously need to know this to be able to work out at what point the ‘clock’ began to tick.

We’ve seen that it would have been the same as in the atmosphere at the time the specimen died. Do scientists assume that it was the same as it is now? It is well known that the industrial revolution, with its burning of huge masses of coal, etc.Libby knew that if these figures were correct, it would mean that the atmosphere was young, so he dismissed the results as being due to experimental error!

I am just blessed to be here because that situation could have gone really bad, but God gave me another chance.… continue reading »

Rather than assigning blame for problems, discuss what went wrong and what each of you could have done differently. If you reach a point where you know reconciliation is no longer an option, voice that to your spouse.
