I'm not a scientist but it seems to me that if you take an object whose opaque components are compacted into a sphere, like a planet, and crushed it into dust which spreads out that the total light blocked by the dust would be greater than that blocked by the sphere where so much more of the matter is in the shadow of the object's surface by a large order of magnitude. If you had two gas giants collide there would result an awful lot of previously in-the-dark matter newly exposed to (and blocking) the star's light.

With the one example we have, out of one billion years of complex life forms with god knows how many species we are aware of 1 species that has the intelligence and life cycle necessary to establish civilization. That species has been establishing and maintaining civilizations for let's generously say 10,000 years. Of course there are a hell of a lot of planets out there also.
