The physicists at CERN are measuring the speed
of the protons in the LHC to be less than c.
Putting different indexes on the V can't change that fact.

And of course this speed is real, and not imaginary.

I am keeping the rest of the translation because
it is so incredible funny!

See? Hilarious, no?

So you claim that we must know the protons proper time per
cycle to measure the real speed of the proton in the lab frame!

Even more hilarious! :-D

BTW, is the proton which remain at the same place in its
frame of reference the same proton as the very jumpy proton
in the lab frame?

Yes, of course!

Even a child would be able to calculate that when
the proton is moving around the 27 km circuit,
and it passes by the same point every slightly more
than 90 μs, then its real speed is slightly less than
27000m/0.000009s = 3000000000 m/s

Who fell in this trap?
