I agree to many of your points.
There is no empty space and space was abolished only due to the fact that it was not understood.
Gravity particles moving in all directions explained gravity 300 years ago.
Absolute time and space are needed, and the illusion of time dilation is in reality a CLOCK dilation.
Determinism can also be possible but create the illusion of chaos at the higher observable level due to hidden variables.
The introduction of c as a speed limit is only due toa a singularity in a WRONG theory.
However, in my opinion Michelson Morley's tests are useless and GPS tells a different story by indicating 1-way light speed.
