We say that the input and output of water is in equilibrium.

the accuracy of carbon dating-6

We stick the garden hose in and turn it on full blast.

The water coming out of the hose is analogous to the continuous production of carbon-14 atoms in the upper atmosphere.

It's a great argument except for one, little thing.

The water is coming out of the hose at a steady rate as our model assumed!

To that end, he quoted some authorities, including Richard Lingenfelter.

Having accomplished that, Morris concluded that the barrel was still in the process of being filled up and that, given the present rate of water coming in and leaking out, the filling process began only 10,000 years ago.

Creationists don't want their readers to be distracted with problems like that -- unless the cat is already out of the bag and something has to be said.

Tree-ring dating (see Topic 27) gives us a wonderful check on the radiocarbon dating method for the last 8000 years.

The barrel represents the earth's atmosphere in which the carbon-14 accumulates.

The water leaking out the sides of the barrel represents the loss (mainly by radioactive decay) of the atmosphere's supply of carbon-14.

This nullifies the carbon-14 method as well as demonstrating that the earth is less than 10,000 years old. One suspects that the scientific world would not be using the carbon-14 method if it were so obviously flawed.
