If You Ever Wanted To

[Glyn]

Yes you can reverse the process, but it’s very inefficient.

Start with a system with one ringworld or sphereworld.
Step:
1) Use a nebula creating ship to destroy system. (Note: Order must be issued from a sun in another system.)
2) Remove system nebula. This will leave an asteroid in place of the ring/sphere-world.
3) Create a new star
4) Use new star to create a new ringworld
5) Then Repeat Steps 1-4 until you have enough asteroid fields.
