Yeah I guess if you built a BIG enough dome such that it completely surrounded the planet, it would theoretically need no hard structure and could be entirely composed of fabric. Effects of gravity would be net neutral so it would just be a giant bubble with a planet in the center, floating above the surface at a relatively constant altitude, deflecting solar winds and containing heat and water vapor. Desireable global warming. Over time the pressure inside the bubble would increase and we could control it to be 14.7 psi, identical to earth. We could control the temperature by varying the reflective properties of the bubble. And we could send all of the mother in laws there with jet packs to patch meteorite holes. Oops, didn't mean to go personal there.
