Re: "Real" ringworlds
The problem is, if you can build one of these, why do you need it? You would probably have mastered mass-energy convserion, intergalactic travel, and many other things. So why go through all the effort? Yes one of these has the area of 3 million planets, but thats only a fraction of all the planets in the galaxy.
