Well, I think it would have to be. The thing is, I think coriolons are only felt by freely moving matter, like water, air, and swinging pendulums. If an object's at rest, they pass right through it, like neutrinos; but they differ from neutrinos in that when an object is exhibiting significant kinetic energy, they affect the object's trajectory.
Well I agree with you on that... based on your hypothesis, it definitely would have to be.
However, the pendulum itself could be classified as a conventional instrument. It wouldn't be possible to utilize the basic concepts used in the pendulum to fashion any other type of detection instrumentation?
Such as one that could allow us to gauge the strongest particle fields on the planet, perhaps. From there, with just a few calculations, I'm sure it would be possible to track the exact movement of these particles. I would be fascinated to see something like that represented graphically.
