Suppose that 2 observers are sending light signals to each other. At some point, ifIf each of them are stationary in relation to a nearby galaxy, but each of these are separated by so great distance, they will be moving apart at speed which is higher than light: 
How's the type of violation of causality seen in the Krasnikov tube avoided?
