Abstract
"Predictions have value," writes a prominent space scientist about planetary theories. "The classic test of a theory," he says, "is its ability to predict. Successful predictions are so rare that they are usually regarded as compelling evidence in favor of the underlying theory." If that is so, then the Voyager II space probe has provided "compelling evidence" in favor of the creationist's theory of the origin of planetary magnetic fields by confirming two of its predictions. A main tenet of consequence of creationist theory is that planetary magnetic fields must be much younger than the billions of years required by evolutionary theory.
