Figure 19.5, curve C, shows the dipole field strength calculated from measurements of magnetism of lava flows and of artifacts such as pottery and bricks, whose age can be determined.

Even before the tree-ring calibration data were available to them, he and the archeologist, Evzen Neustupny, were able to suggest how much this would affect the radiocarbon dates.When the dipole moment is strong, carbon-14 production is suppressed below normal; when it is weak, carbon-14 production is boosted above normal.What the magnetic field does is to partially shield the earth from cosmic rays which produce carbon-14 high in the atmosphere.That is, the equilibrium point should have long since been reached given the present rate of carbon-14 production and the old age of the earth.The next step in Henry Morris' argument was to show that the water level in our barrel analogy was not in equilibrium, that considerably more water was coming in than leaking out.We say that the input and output of water is in equilibrium.

The water level just sits there even though the hose is going full blast.

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.

(The barrel is made deep enough so that we don't have to worry about water overflowing the rim.) Henry Morris argued that if we started filling up our empty barrel it would take 30,000 years to reach the equilibrium point.

Thus, he concluded, if our Earth were older than 30,000 years the incoming water should just equal the water leaking out.

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