I lean towards Tessla here...
HAARP is all about frequencies and resonance.
I am very convinced that one of the LHC clues lies in the same area. The length of the circle * speed of the particles * mass of particles * number of sweeps = energy * frequence = VERY INTERESTING RESULTS!
But, what do I know about these things? The only one who really was open whith theses theories was the old Serbian fellow Tessla...and he was litterally destroyed and humiliated, wasn't he?
