A pair of starships train for a mission. They are asked to fire at each other at a specified time, and immediately start their engines in order to dodge each other’s attack. If either of the ships fires too early, it will destroy the other, and this establishes an unmistakable time order between the firing events. If a powerful agent could place a sufficiently massive object, say a planet, closer to one ship it would slow down its counting of time. As a result, the ship farther away from the mass will fire too early for the first one to escape. © Magdalena Zych
