Lets say that they had invented a way to go at the speed of light. Now lets say that theres earth and very far away there's planet X. It takes 10 days at the speed of light to get to planet X from Earth. Explorers go to planet X and set up a colony. Then Earth wants to send them a message by ship. But the message would obviously be pointless considering that a century has gone by. Ok lets say now that the message didi get to the colony wanting them to come back to Earth. When they leave for Erth and get there a century has gone by on earth. If the message was urgent then they would be to late for the message to mean anything.

MY question is how will they get the message there with it making sense. And how will they get back in time for the message to make sense.
