How Many Core Collapse Supernova Supernovae Have Produced Black Hole?
If you take a relatively common asteroid, something that's about a kilometer in diameter, what I'm thinking of is just scrap material laying around in our solar system and break it up into 10 kilogram chunks. Then you would have made at least a trillion black holes outpacing the star production rate by some three orders of magnitude. That's one asteroid. So now if you envision an intelligent species that would potentially have been devised initially by humans, but then based on superconducting optoelectronic networks, they don't have to fill the galaxy. They could potentially dramatically outpace the rate at which stars are producing off-screen universes. And then wouldn't you expect that that's
