[QUOTE="Scott DeWar, post: 6713301, member: 49929"] Ok, lets use a less complicated example: Poxima Centari, and theorize an Earth like (M type is it?) at a livable distance of 8:32 light mins away from Centari. It is 4.3 light years away. We have a thriving colony there and a ship headed there for trade. Sol 3 sends a message via modulated light to the planet to warn them that the ship has an escaped criminal looking to exact revenge on some leader on Centari 3. I do not know how each is moving in reference to each other, so for the sake of argument and simplicity they are close enough to each others movement that no dilation due to velocity occurs, and each planet is nearly the same mass so no gravitational dilation occurs. Now the ship is traveling at .9 c [chugga chugga chugga] leaves on 1 October 2115 murderer escaped the week before, and snuck on board He was discovered to had snuck on board on 2 October 2115, and the message was sent. message will arrive 4.3 years later, ship will arrive 4.777... years later those on the ship will have felt aprox .1672 years pass on the trip, or 61 days. It is now 1 December to them. the criminal barely had time to get settled in and act like a crew member, or what ever, when he is greeted by the centary prime federal forces. ok, here is what all of this is getting to: Do I understand this right? or does the message intelligence get scrambled up in timespace?
