  In this work a general relativistic generalization of Bell inequality is
suggested. Namely,it is proved that practically in any general relativistic
metric there is a generalization of Bell inequality.It can be satisfied within
theories of local (subluminal) hidden variables, but it cannot be satisfied in
the general case within standard quantum mechanical formalism or within
theories of nonlocal (superluminal) hidden variables. It is shown too that
within theories of nonlocal hidden variables but not in the standard quantum
mechanical formalism a paradox appears in the situation when one of the
correlated subsystems arrives at a Schwarzschild black hole. Namely, there is
no way that black hole horizon obstructs superluminal influences between spin
of the subsystem without horizon and spin of the subsystem within horizon,or
simply speaking,there is none black hole horizon nor "no hair" theorem for
subsystems with correlated spins. It implies that standard quantum mechanical
formalism yields unique consistent and complete description of the quantum
mechanical phenomenons.
