I can't help but speculate about Bio-tek or Nano-tek on this buut... The raw materials could be avaible in a solar system abundantly. What's mind boggling to me is the extraction of the materials, moving them such distances at such masses, construction of the sphere and maintenance of it.

That might be a very long descent
But I think a dyson shpere would still have mass, and therefore some gravity of its own. Its own gravity- at that distance may hold more influence than the star would.

I don't think it would create that much pressure. Even so, that energy would be collected and converted for other uses.

Get a really big umbrella up near the poles...
