In my UFT, universal resonance is explained not by "super"fast light going in the opposite direction, but by instantaneous light connecting source and receiver. The entire "pathway" of the light action is achieved and manifested at the same time.
No light speed, no waves undulating or particles flying through space. A pressure field, manifest both astronomically and locally as light, voltage, gravitation, nuclear force... I've defended this on other threads, but couldn't help pipe up after Lizzie's "superlight" post above.
Truth extends beyond the border of self-limiting science. Free discourse among opposing viewpoints draws the open-minded away from the darkness of inevitable bias and nearer to the light of universal reality.
