Query: Relativity and Nonlocality   The basic physical structure of the relativistic theory of gravitation is
discussed. The significant role that the Hypothesis of Locality plays in
relativity theory is elucidated via the phenomenon of spin-rotation coupling.
The limitations of this hypothesis are critically examined. A nonlocal theory
of accelerated observers is presented and some of its observational
consequences are described.
