Controversy over carbon dating

Because the controversy surrounding Barnes's geomagnetic age model has spilled over from the pages of creationist periodicals into the classroom, the court room, convention halls, and even into pulpits, it certainly behooves clergy and Christian laymen alike to be aware of its implications and to have the means whereby each can evaluate its validity from both a scriptural and a scientific standpoint.

That evidence is provided by the rapid depletion of the energy in the earth's main magnet, its electromagnetic dipole magnet in the conductive core of the earth." Creationists who believe in an old earth have also attacked Barnes's model because it limits the earth's age to a maximum of ten thousand years.

In fact, for the first decade of its existence noncreationist scientists never even took notice of Barnes's proposal.

It wasn't until 19 when the creationist controversy erupted in the classrooms, when the Arkansas and Louisiana creationist legislation was being challenged in the courtrooms, and when scientific societies were beginning to have papers attacking creationism at their annual conventions that Barnes's ingenious method of dating the earth by its magnetism was brought to the attention of the scientific world. Geological Survey as an expert in radioactive dating, especially the potassium-argon method.

The magnetic forces have left their imprint upon rocks, such as lava flows, and in loose sediments, such as lake beds and deep-sea sediments, and sensitive instruments can decipher what some of the magnetic forces were at the time the rocks and sediments were first deposited.

One branch of paleomagnetism, called archeomagnetisrn, attempts to analyze the forces of the magnetic field as derived from archeological artifacts subjected to high temperatures, such as pottery and bricks from kilns.

While the magnetic forces are very complex and are continually in a state of flux, we can clearly identify the main component of the total magnetic field, and it is called the dipole field.
