I doubt it would be billions of light years away, otherwise they'd probably choose something a bit closer. After all, the sleeper ships would be most likely on auto-pilot for the trip, since everyone is frozen, so if I were one of the technicians taking care of 'em, I'd be afraid that the longer the trip, the more chances the material has of degrading in functionality.
THEY TOLD ME I COULD BE ANYTHING SO I BECAME A SIGNATURE PLS HLP
