Factual error: While measuring the Electromagnetic Field (EMF) being given off by Stonehenge in the film, a scientist exclaims that the frequency is increasing to over 100 Gigahertz, and is approaching radioactivity. This is absurd. EMF is radiation of electromagnetic waves over a wide spectrum of frequencies. Its strength depends on the frequency at which it is measured, with no relation to radioactivity whatsoever. It has a magnetic and an electrical component, but no nuclear breakdown as such.
