"Dono" looking for an Enrrabadore spew in the message:

The Sagnac effect does not contradict SR. You are an imbecillic troll

In Sagnac experiment, light speed is *measured* not to be
independent from either, the source and the observer.
That's so obvious and so many times proved, by
so many, that it should hurt very bad. Doesn't it Dono?

Of course, nothing that one cannot re-arrange, like
making 1+1=3 should be easy for any good relativist
using a convenient coordinate system, perfectly engineered
for the show-off.

Now, please send the "jpg" pictures. Got new ones?
