Suppose an explosion occurs at $x=0$ in the Home Frame (event $A$ ). Light from the explosion is detected by a detector at position $x=-100 \mathrm{~ns}$ (event $B$ ) and by a detector at position $x=+50 \mathrm{~ns}$ (event $C$ ). Events $B$ and $C$ are causally connected.

Question

Quizplus · Accepted Answer

Events $B$ and $C$ are not causally connected because they are simultaneous detections of the same light signal from event $A$, and neither can influence the other.
