Info on the free decay model for terrestrial magnetic fields.
A young earth? That is religion, not science.
Science falsified that idea decades ago, and the evidence since then has continued to pile up.
The RATE boys tried an experiment with over a million dollars of creationists money, and failed to put a dent in established science. Of course, they refused to believe their own results!
Here are a couple of links:
Assessing the RATE Project: Essay Review by Randy Isaac
Sorry, even creationist research fails to support a young earth.
somewhere in my peabrained memory, I recall an article that speculated the magnetic fields of some planets must be younger than thought, because physics and natural law dictated that fields just couldn’t last 4 or 5 billion years plus because of a gradually cooling core. of course, I could be remembering incorrectly; if so, please feel free to slap a dunce cap on me.
