Einstein told us that the speed of light must always, not only appear, but BE the same in every frame of reference no matter how fast we are moving towards or away from it. So even if you are moving at half the speed of light towards a light beam, the entire universe must conspire to either "speed up" or slow down your "time" to account for this difference.
If that makes sense to you, you are no longer sane. You cannot create scenarios of two mutually exclusive events at the same time and call that reality. This is fundamental to reason.
To show this contradiction, consider you are running away from a light beam and towards another at the same time. You move at half the speed of light. Of course in real life you will encounter the light you are moving towards first, but in Einstein's universe both beams MUST (in your world) hit you at the same time. However, in Einstein's universe, someone else will see them hit you at different times because they also MUST see light travel at a certain speed. This is just plain fucking stupid.
At best you can have an illusory effect, but to confuse that with a real difference in simultaneity is to truly give up on reason itself.
Special relativity uses EM waves for observation. And suddenly omit simple fact that EM waves have finite speed. All observable effects of Special relativity could be easily explained just as effects of finite speed of observation.
Impossibility of FTL information transfer. There are no any "telegraph to the past" paradoxes at all.
Impossibility of syncronizing distant clocks. Your OS do that regulary without any problems just by taking in account the "speed of observation". Simple thing this kike "genius" could not understand.
And so on. There is no any speed limit. You don't need infinite energy to reach speed of light. There is no any paradoxes or time travel at all in travelling with speed close to speed of light or faster. Exactly like there is no any paradoxes in traveling with speed close to the speed of sound or faster.
It is a fact, proven by perfectly documented and replicateable experiments. What theory will appear behind that experimental fact does not really matter. Information could be transferred faster than light. All special relativity should be in the garbage bin long ago.
Special Relativity is mathematecally correct. But all this math is just a corrections have to be made on the side of observer to get how remote moving things look like in reality. It is not how remote things really are.
