[Space] Ditching Relativity, with minimal collateral damage

[vicky_molokh]

Greetings, all!

Probably the easiest solution to resolving many paradoxes emerging due to FTL technologies in Space/Spaceships is to simply ditch relativity. However, this cannot pass without consequences. So . . . this leaves some holes to be patched. Here are some that I figured out:

• Gravitational time dilation. I suspect this may be stated to simply not occur in this universe, however see below.
• Frequency shift. Blueshift/redshift. Can this be ditched too without consequences? Or can it be harmlessly attributed to light being slowed down/sped up slightly below/above its normal vacuum speed while under the effects of gravitational force? (I guess gravity is most likely a force in this universe, but not sure).
• Light deflection and gravitational time delay. Can either the freefall universal rule be applied to photons, or a law of nature state that the freefall rule applies twice to photons/light, without any further consequences?
• Gravitational Waves. Can they be applied to a non-relativistic universe by simply fixing their speed at either c or infinity? Are there better solutions?
• Orbital physics. Orbits no longer decay? Orbits decay as usual with slight change in explanation? Anything else?
• Black hole physics. Do these become simpler by simply stating that the 'horizon' is a de-facto case of everything simply being pulled in with enough acceleration to reverse the direction of a photon trying to come up from the black hole surface?
• Anything else?

Thanks in advance!
