Keith Hunter expands on his controversial theories. His work on nuclear weapons is based on the work of Bruce Cathie. Cathie first put forward the theory that nuclear weapons have certain limitations which have been kept secret. These limitations concern the geographical position of detonation, which must be at a specific point and time on the planet allowing resonant energy to flow into the device. Keith also believes certain military facilities across the globe have been geographically positioned such that the distances separating them represent a harmonic "fit" when compared to the circumference of the earth itself. This leads him to conclude they are "communicating" or using resonant earth energy in a similar way he believes the pyramids did.
