Inspired by The One Million Earth Solar System.
A civilization wants to create a solar system with a lot of earth-sized planets. How would they go about building it? Specifically, how would they move planets to the new solar system?
- There are no planets in the system
- The civilization has plenty of planets but they are all in different systems
- The civilization has FTL travel, and can build very large starships if needed
- The price of FTL is based on the mass of the object being transported
What would be the best way to transport the planets, as small payloads, pre-assembled or whole planets?
How to move many planets, possibly up to one million of them, to the new solar system?
