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.
If you are not aware, Nimtz experiment is extremely cheap, relative to many scientific experiments of such significance. You could replicate it in your garage at weekend and measure superluminal speed of quantum tunneling just for fun.
Also, you could not prove impossibility. You only could proove opposite. It is Einshtein declared impossibility without any reason and in was Nimtz who proove opposite.
Quantum tunneling can’t transfer information. That’s how it can be superluminal.
False. Different experimenters successfully transferred different kinds of information, from original Nimtz experiment pulse whose form does not change during transmission, to the music, literally.
Whatever theory is behind, it defintely allows FTL information transmission. And looks like tunnelling time is just zero. So information could be transmitted at infinite speed.
Theory of quantum tunelling is very far from completeness. You just cant do such bold and fundamental statements basing on incomplete theory. There could be tons of explanations, from different nature of tunnelling to timeless virtual space in cavity for particles.
Gonna need direct citations for that. You can see that spin has changed but not how it has changed, so you can’t convert information that way.
Don’t we need tachyons (with mass) to exist for any of this to be true? And if it’s true, why does causality exist? It obviously does. If entropy can be magically defeated by random fluctuations in the Universe itself (and not just through the concerted efforts of petawatts of power and a machine built by consciousnesses), how can the balance of matter and energy actually have formed anything for long enough to form anything else without an effect happening before a cause and preventing the cause from happening in the first place?

And so on.
No, we don't. Tachyons are ugly crutch to specifically satisfy special relativity dogmas. They are not necessary if you are not sticked to Einstein dogmas.
FTL does not violate casuality. That infamous Minkovsky diagram is total bullshit based on unfounded dogma of speed of light as dogmatic limit. FTL is just a path with higher angle than light cone and nothing more.
Imagine, you have supersonic plane flying toward you and observe it with your hearing by ears. You will definitely observe "casuality violations". Like you will hear sound of touch-off after the sound of landing. But is absolutely does not mean that there is any real casuality violatons. Plane for sure still arrive after departure, but it moves faster than information you use to observe this events from your frame.
Same with FTL. If someone who use EM waves with specific speed of light to observe FTL processes should just account a simple fact that he use "slow" EM waves to observe faster process and fix his observations using that knowledge to get a real picture. And not to try to pass his observations for reality.
Principle of accounting for influence of method used for observations is unseparable for any measurement. F.e. when you measure resistance with ommeter, you adjust your measurement by resistance of wires and probes. Especially if you measure resistance close to the resistance of ommeter probes. You get observation of 0.1Ω. Your wires and probes have 0.05Ω resistance. So, you correct your observation by that 0.05Ω and find real measured object resistance as 0.05Ω. But somehow Eistein sect is absolutely unable to do exactly same thing when they do their observations. And come up with all that Minkovsky space bullshit and "casuality violations".
It's really insane, if you look at all that relativity stuff from the point of a regular engineer.
FTL does not make effect happen before the cause. It does not lead to time travel or any other garbage. Just effect follow the cause faster than some ignorant observer will do its observations and that's all.
If you have FTL data transmission line between Berlin and Los Angeles and it takes twice less time than conventional one to transmit a message, message still will arrive after sending, just two times faster, and that's all. Fact, that some side observer could see events of departure and arrival in different order means that this observer just choose bad means of observation that need correction to find real way of things and nothing more.
