a hundred years ago it was scientifically impossible to travel to space with in result achieving imba speeds to the earth's frame of reference...
so that THEORY of general relativity which works fine in many (note NOT ALL cases) might have a few bugs in it so don't knock it...
its difficult to say what would actually be the most vcomprehensive representation of the world around us... human intelligence is at an infant stage now (needs more microchips/ram/matiX to be zOmg imbA or smth)
so asmuch as it pitys me to say this we will never know for sure about this "lightspeed" well at least not in the near future and even when we learn all about the workings within our universe... what about... ah nvm humanity won't survive that long anyway
