Two separated events are simultaneous in one inertial frame and occur far enough apart that light from one cannot reach the other in time. What kind of separation is this?
A
Timelike separation, so all frames must keep the same time order.
B
Spacelike separation, so some frames can assign different time orders without allowing causation.
C
Lightlike separation, so the events must be connected by one photon.
D
No separation, because simultaneous events always occur at one point.
