Re: I dare to relativists to explain local time: t-vx/c²

Special Relativity is fairly simple and easy to understand.
But it is not self-evident. It is not understood by those who have not
learned it. Some people simpy find it too uninteresting.

 Absolutely not.  I studied it for forty years, and if at first it is a bit hard, we say to ourselves that, perhaps, it is not a lack of intelligence on the part of the reader.
But, no. It is an intellectual fraud.
Not everything, obviously, Dr. Hachel is NOT anti-relativist, quite the contrary.
But he has the fault of pointing out the lie of physicists, who say they understand but do not understand, and worse, of proving it.
For example, the first major proof is that of the contraction of distances, I am told that if I move at v=0.8c, a distance of 12 ly will appear to measure 7.2 ly.
This is a lie by omission, because I am not told which observer will see this.
Implied "all the observers of my frame of reference".
However, this is false and mathematically stupid if we pursue the idea.
How can an observer see a body moving on 7.2 ly that is coming towards him with a relativistic apparent speed of 4c and during a proper time of 9 years?
No one has ever been able to answer me, except with insults, whining, and bullshit.
Same thing when I explained the radial contraction of a rotating disk and gave the logical equations that go with the concept.
They wanted to explain to me that it was false, but without being able to represent what a seven-year-old child would SEE, observing a disk of 1 meter in diameter placed frontally in front of him and rotating with a relativistic angular speed, a circumference that contracts (which is true) and an invariant radius (which is false).
No, no, we must not say: "physicists are intelligent, they understand what they are saying". It is false. They just understand the mathematical operations, but without understanding that what they write is physically wrong, even ridiculous.
