Re: (TFT) Space travel - galaxy sized dyson spheres.

Yes, the Wiki is correct that gravitational forces would cancel. I think you are right about the unevenness of solar wind, so there would need to be a way to balance all that. But if you can get the darn thing there in the first place, then I doubt that station-keeping is going to be a tough engineering problem for someone who has solved the construction problem. Not to mention for someone who is so bored that they are doing something so inefficient as making a Dyson Sphere.

Assuming it's actually a perfect sphere, and was perfectly placed, wouldn't
gravitiational effects cancel?  I think solar wind doesn't blow equally
hard in all directions all the time, so the reduced surface-area of a net
would be better.
