I have a problem with causality being hampered by the speed of light.
Just because I didn’t see something happen before its effect takes place doesn’t mean that it’s not possible. Why should my perception of the cause have anything to do with it?
Yes, *most* things happen slower than the speed of light. But why is that necessary?
Yes, yes. E=mc^2. But Einstein was *looking* for light to be a part of it. His initial postulate was “what do I see if effect comes before cause?” and based the whole analysis on the idea that cause must precede or be at most simultaneous with effect. That’s the “unprovable” axiom at the bottom of it.
I don’t have an experiment to prove otherwise. But I still can’t figure out why light speed should have anything to do with causality.
