Crazy idea: very expensive hack that moves a Dyson Sphere.
Can only be done on an unclaimed planet.
Can only be done if the Dyson is currently friendly to you.
Costs a LOT of Hacking Points (like 100 or 150).
Cost goes up by 50-100% if repeated.
All gatlings are destroyed while the sphere is moving, and it moves really slowly.
Possibly the sphere is killable while in motion, so you have to protect it while it moves, and possibly it gets exos sent at it the whole time.
