Historically, a long time before quantum mechanics, Lorentz suggested that some disturbances, like waves, could be transmitted with traveling particles through a certain medium without moving it. At that time, instead of careful analysis of the systematic errors, some scientists chose to postulate constancy of the light velocity to explain why the earth appears not to rotate around the sun in the Michelson experiment. Mathematically, it was based on the Lorentz transformation that preserves a wave equation in the moving frame instead of time invariance in the Galilean transformation. Since it equally applies to any wave motion, the anisotropic values of the velocity of light are used in Einstein's original manuscript and all applications, e.g. a global positioning system (GPS). General relativity is playing a crucial role in the GPS algorithms. However, its field equations do not lead to attraction between material bodies, and the small spectral line shifts in enormous gravitational fields of dense stars invalidate the principle of equivalence of gravity and acceleration.
Lorentz was ahead of his time and this approach led to the natural introduction of the field values (group velocity and intensity of de Broglie waves) into Maxwell's equations, and could lay the foundation to direct conversion nuclear energy to electrical. A process, pioneered by WETC, would avoid keeping the gaseous fission fragments restrained in fuel elements, an innovative strategy used to monitoring and control a coupled fast-thermal reactor, medical isotope production unit or nuclear-pumped laser. It can produce very high power in a steady state or pulse mode for a fraction of the costs and with much less radioactive hazard than a radioisotope power unit. Fiber optic sensors based on Fabry-Perot or Sagnac-type interferometers and White Rabbit (WR) technology can be used to identify critical reactor parameters.
The WR, an Ethernet extension for synchronization, precision time and frequency transfer, is able to coexist a fiber optic gyroscope with data channels in wavelength-division multiplexing systems. The WR can compensate temperature fluctuations, but there are non-environmental effects, e.g. the Sagnac correction that can be analyzed by the fiber optic, satellite laser ranging or radio astronomy technique. Radio astronomy technique can image the entire sky and serve as active or passive over-the-horizon radars and in autonomous navigation systems.
If two signals starting and ending at the north point, the experiment is sensitive to the earth angular rate ?=7*10-5rad/s. If time and frequency differences of east-west clocks are measured using north one as the reference source, the steady result should by same. Also, there are variations in the propagation time t'=R/c' caused by the changing orientation of the signal path relative the orbital or galactic velocity V. The signal speed c'=c+Vsin?t and dt'/dt=-?RVcos?t/c'2.
