Abstract

After a review of the chronogeometrical structure of special and general relativity, it is shown that the problem of clock synchronization lies at the earth of the following problems:
a) quantum field theory in noninertial frames
(TorreVaradarajan nogo theorem);
b) relativistic atomic and boundstate physics
and relativistic entanglement;
c) ACES mission of ESA to put high precision lasercooled
atomic clocks on the space station to test Earth's
gravitational redshift to order 1/c^3 and to arrive to
define relativistic geodesy beyond GPS;
d) the possible role of the gauge variable connected with the definition of the istantaneous 3space (the York time in the York canonical basis) in the attempts to explain dark matter (Cooperstock) and dark energy (Buchert, Ellis) only in terms of Einstein's general relativity.
