Ship size vs. weapons

I know there are experiments supporting special relativity. However, general relativity does not assume light is some ultimate speed, nor does it assume that it is a constant speed. Furthermore, there have been experiments in quantum mechanics that show quantum tunneling effects can move a particle faster than light speed. Also, there are some big problems with assuming that going faster than light speed results in going back in time. The big thing is how do you actually go back in time?
My final point is that just because 2+2=4 does not mean that 7-3 does not equal 4, nor does it mean that -i*4i does not also equal 4. My point is that just because the experiments support special relativity does not mean that they cannot support another different theory that is inherrently different than special relativity.
