This is proven by the magnetic characteristics of iron- (and other ferrous metals) bearing rocks and strata found in the earth's crust, so the "haters" who just wouldn't be happy if you hung 'em with a new rope have absolutely nothing to base negative comments on in this regard which are rooted in scientific fact.
Lighten up and enjoy entertainment for what it is... ENTERTAINMENT!
Otherwise, enroll in classes, and do your thesis on, subjects that will make you a recognized leader in your field of study.
