Upper limits on partial Dyson spheres in the Milky Way

I believe Dyson spheres don't rotate, so they just have to be able to handle the stress of the central sun pulling uniformly on the surface.

Per the Ringworld not being stable, I think the same math applies to the sphere as well as the Ring, so the sphere will need attitude jets to maintain position with respect to the central sun.

Dyson swarms seem drastically easier to construct. We could build one example of that habitat fairly soon!

Ahh a non-rotating sphere makes sense! If it is light enough then solar pressure could help keep it up too, and it could have openings to adjust pressure which would serve as attitude jets. Hmmm this does seem possible after all, thanks for the tips!
