Somewhat relevant question: I've read that a completely solid Dyson sphere/shell would be impossible because it would not orbit or be gravitationally bound to its star; the shell and star would drift apart and eventually collide.

How do physicists know this, given that we've never observed anything similar to a Dyson sphere before?
