Science has a history of being wrong for a span then corrected then being wrong then being corrected

It is a normal scientific process. That's what Einshtein worshippers try to break.

In normal situation, after first succesfull replication of Gunter Nimtz experiment, scientists had to at least deeply revisit Einshtein "relativity" and came out with new theory, where is no any casuality violations possible when signal is transmitted faster than light. But that's not what happened. I don't even know who is hated most today - Gunter itself who get 4.7c or those guys who replicated with much more advanced instruments and come to conclusion that signal tunneling takes zero time, i.e. have infinite speed. This obviously falsifies "special relativity". Nobody could disprove experiments results, so the Einshtein crowd turned to lies and personal attacks.

Because Einstein at his worst was a once in a generation thinker

He wasn't. He was made "media darling" to circumvent normal scientific process. Whole life and career of Einshtein is suspicious at minimum.

many very smart people have spent a lot of time trying to disprove his observations

Problem is that Einshtein doesn't have any observations at all. His relativity is purely mathematical excercise. As you might know, math is not a science, it is a language for science. And as in inay other language you could spell total bullshit in math that have nothing to do with reality.

Again, if you still don't get the trick done by Einshtein and his handlers: Both relativity theories completely miss the point that observation is a process too. And it is done in all Einshtein reasoning using light, which itself introduce distortions in observation, because it have limited speed and vulnerable to gravitation. Lorenz transforms show not that something elongating, or time slow down in moving object, but that observer observe this elongation and slowing because he use light to observe, Same is with general relativity. Light could bent near massive bodies not because continuum is curved, but because gravity affects energy, just like it affects mass.

Taking all of that you will get exactly same equations, that equally predict what you observe, but they will have completely different meaning. And of course, there will be no any "fundamental" limitations that was sucked from Einshtein finder with single purpose - to cancel any research in unwanted directions like FTL or gravity control.

Interesting, that unlike all other scientific theories, Einshtein relativity is a first and only scientific theory that never produced any practically useful inventions, but on the contrary, closed a ways to many important possible breakthroughs.

Think about it, why that only theory with so weird influence on the science is so dogmatically protected from any possibility to be disproven. It is literally used as "Einshtein was genius, and if you find something that does not fit, then you are just fool and does not understand relativity". It is not a science at all, it is religion.
