 That's not what I'm talking about, and I'm saddened that Paul B. Andersen, who is not an idiot, who is not a thug, who is not a bandit, does not do the effort to understand what I have been saying and why I have been saying it for 40 years.
It is obvious that if I place a proton in a circular ring, I will have to calculate very precisely when the proton passes, and that this calculation can only be done by the laboratory watches.
 But if I could put a watch on the proton, and I asked it how long it takes to complete one revolution, the proton would tell me "much, much less time than the lab clocks say."
This is called duration dilation.

The speed you have called "the real speed" is not the proper speed of
the proton, you really think that the speed (dx/dt) where t is the time
in the lab frame is 6947c. The fact that you think "the proton rotates 78 million times per second" shows that.

You are saying that when the physicists who are operating the LHC
know that a proton has gone around the circuit once, it has really
gone around the circuit 78000000/11250 = 6933 times.

 Paul thinks I'm telling him that when the proton makes one revolution, in fact, it makes 6947 revolutions. This is absurd.

Yes, and yes.

No one has ever said such stupidity.

Yes.
