Re: Doubts
"While I would agree our perception of events would be altered if we broke the light barrier (B then A), the actual event progression would be the same (A then B) for the rest of the universe"
But the problem is that there is no such thing as "the actual event progression". Einstein stated that all reference frames are equal, so it is not the case that there is one observer whose measurements are somehow actual or true, while everyone else's are just perception.
Furthermore, just like quantum mechanics, there is no "true" reality which we measure approximately with instruments. Instead, reality is just what you measure, and nothing else. Thus if all your measurements indicate that B preceded A then that really is what happened, at least in your reference frame.
