I read about purported antigravity effects. The magnitude of magnetic permablilty usually makes gravimagnetic interactions inconsequential except in coherent states. Yet there continue to be reports of experiments which cannot be replicated. You would think someone would just go there and take a look.
One experimental setup is described as a rotated, special size, asymmetrical capacitor, (with one plate superconducting and the other not), pumped with high voltage pulses whose frequency is optimized for the size of the plate to give the largest gravitational pulse. Both plates have the same chemical but different crystalline structure. The magnitude of the EMP theoretically should not depend on the size of the plate, which is actually a disc reinforced with plastic. Protection from the EMP generated is a safety requirement. This all takes place in a vacuum chamber.
Outside the chamber, one “gravity” component reportedly travels at between 63 and 64 times the speed of light and was measured over a length of one kilometer. The force interacts with photons and generates phonons, but does not loose measurable strength. This is the preferred setup because it allows one to vary how the magnetic flux quanta are pinned in the superconductor. The superconductor is of a cupric type that generally displays magnetic anomalies around the oxygen atoms.
Hypothetical application include communication and propulsion devices. The military, of course, thinks of everything as a weapon.
Let us analyze this. In the insulating plate, Cooper Pairs are pinned and flux quanta are condensed. In the superconducting plate, magnetic flux is pinned and Cooper Pairs are condensed. In one plate, magnetic flux quanta are accelerated. In the other, Cooper Pairs are accelerated adding an additional relativistic influence. It sounds like bremsstrahlung with gravitational components is being generated, but high accelation merely enhances the effect; it is not the cause. Note that the plates are not just asymmetric, they are in opposite phases, superconducting versus nonsuperconducting states. What happen to chiral symmetry here?
In spin charge separation states, a positron consists of a magneton and holon. Likewise, an electron consists of a spinon and chargon. A mass of electrons artificially confined in a small space together will split into spinons and holons due to the intensity of their mutual repulsion. Spinons and magnetons are antiparticles. Chargons and holons are antiparticles. In a Pi Flux Phase condensate like this, a Couper Pair is made up of two holons and two magnetons. Calculations show that the intensity of the pi flux is proportional to the area of the circle of the superconducting plate. Since time-reversal symmetry is preserved, perhaps the charges tunnel to the other plate and the spins tunnel as spin -1 gravitons at a speed slightly less than 64c. That is the best explanation I can think of at the moment based on the usual quantum mechanical concepts.
A second implementation uses special, powerful magnets with the north and south poles in extreme proximity to each other while accelerating with respect to an inertial reference frame. The cost of the magnets used to test this was reportedly $10,000. Perhaps Myth Busters should travel to the leaning tower of Pisa to test this. Nobody else seems interested. Haha.
