Quote - Cell phones, TV, GPS - SATELLITES!!!!

Cell phones, NO. TV NO. Satellites NO! GPS yes and is controversial, Sagnac effect!!!

Quote -   use Relativitly to compensate for the difference in gravitational effects caused by Relativity.  Did you not read that carefully? ;

Quote - gain, when synchronizing clocks (using Quantum levels of accuracy - the energetic vibrations of atoms), one must consider Relativistic effects of gravitational fields.  A clock in orbit around the Earth will drift to one on the surface due to these effects.

The result is controversial, not always the results agrre with Relativity and the second important point is the energetic vibrations of atoms variations due gravity and speed are a result of Relativity or due Quantics?
The frecuency of the emited radiation depend on the energy level differemce and energy depend on the mass which is a function of speed and potential, if the speed or the potencial is changed the energy of the electrons is changed and the emited frecuency related by the Plack's constant is changed, as what we measure time as the frecuency assuming that speed of light is constant we think that time has changed as Relativity states, but what has changed are only the energy levels and not time!

Quote - Relativity may not be 'useful' in an everyday sense but it is far from working.  It has been experimentally validated on numerous occasions - starting with the perihelion of Mars, Eddington showing the effect of light passing near to the sun, the spectral shift of astronomical bodies due to acceleration (caused by expansion of space-time or relative motion),

Always the same classical experiments that can be explained by a lot of theories too, I never heard that these experiments were a prove for the other theories.
There are other experiments that contradicts or don't agrre with Relativity.
You have the famous Michelson-Morley whose failure turned as the start and later prove of Einstein's theory, you must have heard this experiment thousands times, but what you never heard is that Michelson-Morley continued with their experiments and had success!!!, too bad, it shows that speed of light is not constant, something that you cannot know.
You also cannot know why the first experiment failed and how it was logical to fail.
There are many cases where gravity doesn't behave as the dogma states....

Quote - the disparity of clocks at varying distances in gravitational fields (conducted with atomic clocks).

As I said before, the results are controversial.

Quote - AThat is why ALL satellites must consider these effects for timing, receiving, and transmission of data.

Realtivity is not used for anything in transmision of data.

The maximun speed is the speed of light in vacuum, well..., something to think:

• At which speed light travels in a diamagnetic medium with permeability 1. ?
• And inside a superconductor?

Stupidity also evolves!
