Equivalence Principle and Clocks
نویسنده
چکیده
String theory suggests the existence of gravitational-strength scalar fields (" dilaton " and " moduli ") whose couplings to matter violate the equivalence principle. This provides a new motivation for high-precision clock experiments, as well as a generic theoretical framework for analyzing their significance.

We survey the role of stable clocks in general relativity. Clock comparisons have provided important tests of the Einstein Equivalence Principle, which underlies metric gravity. These include tests of the isotropy of clock comparisons (verification of local Lorentz in-variance) and tests of the homogeneity of clock comparisons (verification of local position invariance). Comparisons of atomic c...

متن کاملHow Fundamental is the Curvature of Spacetime? A Solar System Test
Are some paths and interactions immune to the gravitational curvature of spacetime? The paths of virtual particles might be – the effect is unexplored experimentally. Were a quantum theory of gravity moderated by virtual gravitons that are themselves susceptible to gravitational curvature, to obey the weak equivalence principle, and to follow null geodesics, then gravitational acceleration migh...
متن کاملClock Synchronisation in the Vicinity of the Earth
The transmission time of an electromagnetic signal in the vicinity of the earth is calculated to c and contains an orbital Sagnac term. On earth, the synchronisation of TCB can be realised by atomic clocks, but not the one of TCG. The principle of equivalence is discussed.
متن کاملGalactic-center S Stars as a Prospective Test of the Einstein Equivalence Principle
The S stars in the Galactic-center region are found to be on near-perfect Keplerian orbits around presumably a supermassive black hole, with periods of 15-50 yr. Since these stars reach a few percent of light speed at pericenter, various relativistic effects are expected and have been discussed in the literature. We argue that an elegant test of the Einstein equivalence principle should be poss...
