I've some vague recollection that there's been discussion in higher level physics that theorises that there should be much more matter in the universe than we're observing and that there must be a lot of 'dark matter' that we're not seeing with telescopes (presumably called that because it lurks in corners, wearing black and muttering edgy commentaries on hipsters).
A few dyson spheres might reasonably explain the lack.
(I did have a notion a few years ago of a Dyson Sphere made up of a million-plus hexagonal tiles, each with a surface area roughly that of the Earth. Debris layered across the interior left a geography 'crammed' between the mountains that had heaped up along the seams. Access was via a 'hyper-gate' that had malfunctioned due to neglect and scoured the galaxy to transport interstellar slowboats into the inside of the sphere regardless of the crews' wishes, leaving a population of unintended colonies from many distinct races. The mechanics of providing a day-night cycle seemed difficult though - what was there, a rotating series of shutters around the sun that left sections of the interior in the shade for 40-50% of the time? Building the thing would be bad enough without requiring moving parts.)
