How Far Would a Generation Ship Have to Travel to Find Another Civilization?

Somewhere out there, if the maps are right, another civilization is going about its night under a different sun. The trouble is the distance, and it is far stranger than the nearest star. How far would a ship full of human lives really have to travel to reach them? Tonight we build that ship honestly, fill it with generations, and follow it outward as the answer keeps sliding away from us, from centuries into something much larger. Get comfortable and let this long ride out toward the nearest other fire keep you company tonight. Subscribe to Space After Midnight if you like falling asleep somewhere far from Earth.
