A great quantum physicist was once asked the question: "Is it true that 
there are only three physicists in the world who understand quantum 
physics?"
He replied: "And who is the third?"
The same goes for special relativity.
But worse.
If I were asked if it is true that only three people in the world 
understand SR, I would be obliged to ask and who are the other two?

There are necessarily things that physicists or fans do not understand, I 
see it very well when I post messages, and everyone is flying at fifteen 
miles.

SR is rotten with errors and misunderstandings, and many repeat things 
without understanding them, or even understanding them backwards.

If I ask a question like:
"What makes the notion of simultaneity relative? Is it the position? Is it 
the speed?"

100% of the 569,874 people questioned will throw themselves on the ground 
holding their sides, because the question will make them laugh so much.

They will all answer: speed!

That's wrong. It's the position.

Romeo on this bench, Juliet on that other one do NOT have the same 
hyperplane of simultaneity.

On the other hand, a rocket crossing the earth at relativistic speed 
(Vo=0.95c for example) apprehends exactly the same universe of 
simultaneity.

By saying things backwards, physicists show that they have understood 
nothing at all.

And by throwing themselves on the ground holding their sides with 
laughter, they show that not only are they stupid, but they are arrogant.

Their problem is that they do not know how to interpret Lorentz 
transformations, and do not understand the geometry of space-time 
(Minkowski was wrong, his "block" does not exist.

A very simple proof that it does not fit.

What is the apparent speed of a rocket moving towards me at speed Vo = 
0.8c? As in the Langevin traveler.
Answer: Vapp = 4c

What is the proper duration of Stella's return trip in the Langevin?
9 years.

This means that during nine years of her proper time, Stella will see the 
earth come back to her, with an apparent speed of 4c.

In elementary school, we learn that then, the apparent path is x = Vapp.Tr

Except that this is a distance of 36 ly which drives you crazy, and 
requires the psychiatric hospitalization of the 569874 people interviewed.

With their contraction distances that are totally misunderstood (if that 
were all) physicists all over the world, arrogant as they are, placed on 
the tray of a scale and me alone on the other, do not carry the weight.

But they will never admit it.

Examples that SR is true, but totally misunderstood because of people like 
Einstein or Minkowski abound.

But I have been repeating it tirelessly for 40 years, the problem is 
human, almost psychiatric or religious: we do not want to see.
