Exactly why the Megasphere isn't a solid structure by any means. In fact, the scientist that proposed the idea of a Dyson Sphere never at all implied it'd be one single structure. What I said is that the Megasphere is a series of structures all around the galaxy, each siphoning power from the galaxy itself and creating a network of power generators and superstructure. So it's not like one giant shell around the galaxy like you seem to be envisioning. It's more like space junk orbiting the center of the galaxy -- except it isn't space junk, just controlled superstructures.
