or once you have the device, when you activate it, the map that you use to select the destination system will calculate distances for you.

unfortuneatly, you cant calculate distances before hand, to see how big of a device you will need.

there are lots of other neat goodies in the SM tech area. create planets, destroy planets, destroy stars. create ringworlds and sphereworlds. create and destroy storms and nebulae. of course, monolith facilities give you some of the best resource production in the long run.
