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.

Paul thinks I'm telling him that when the proton makes one revolution, in 
fact, it makes 6947 revolutions. This is absurd.
No one has ever said such stupidity.
That's not what I said, but: "The speed measured in the laboratory is not 
the real speed, it's just an observable data. The proton goes much 
faster."

In this sense, in relativity, ALL speeds are possible from zero to 
infinity, but we will never be able to measure an observable speed faster 
than c, because of the structure of space and time and the laws that unite 
them.
