One of the most fundamental problems in the history of humanity and the 
very basis of the notion of relativity of simultaneity: how to synchronize 
two watches so that they give the same time at the same present moment?

A little explanation would have been welcome.

Of course, in a Newtonian universe, it is not difficult.

But in a relativistic universe where each observer has his own hyperplane 
of present time?

A slightly blurred line in Poincaré.

Five lines in Einstein who thereby succeeds in the feat of evading the 
anisochronous question.

Nothing in Jean-Pierre Messager (the great critic of modern science).

One would think one was dreaming.
