I don't get Alberto's arguments either.

That's wrong in general and depends on how A reaches B.

I've another riddle for you (rather easy):
Suppose you fly in a spaceship at a substantial fraction of c towards a human colony on planet Blorb. Blorb has a moon. On the moon, there live the evil Zarg. The constellation is as follows:
(Blorb) ---- (Moon) ---------------- <You|= ----
Your sensors detect an energy outburst on the moon and then you detect an explosion on Blorb.
Have the Zarg caused the explosion? Do you attack them?
