QFT in curved space-time
... For the last derivation, we used normal coordinates around some point p, i.e. Γ|p = 0 to get rid of terms quadratic in the Christoffel symbols. Next, we replaced the partial derivatives by covariant derivatives for the same reasons. Since the equation is now tensorial again, it holds everywhere. In ...

If two events are space-like separated, then they will appear in one time order with respect to some inertial frames, but in the reverse order with respect to others. The two event ...
