Phase velocity, quantum unobservability, and the birth of chronal engineering.

In classical and quantum physics, the phase velocity of a wave can exceed the speed of light, but this was considered an "illusion" since the phase is unobservable and does not carry information. The development of chronal dynamics and the technique of time crystals made it possible for the first time to make a phase observable and controllable with an accuracy of 10⁻⁸ rads . It is shown that superluminal phase transfer is possible without violating causality, since it is not associated with energy transfer, but is a synchronization of states in a single chronal field. The way is open to the creation of instantaneous communication and control systems at distances of up to 8.4 m (and more), as well as to resonant energy release (RER). The article completes the discussion about "instantaneousness" that Einstein began and translates it into a practical one.
