> This requires no new physics and no exotic materials. It could be that Dyson Swarms are possible, but we have 0 examples of space industries so far. It could be an economical impossibility, it could be that the means to easily convert matter into energy is discoverable before the means to economically produce a Dyson Swarm, thus a Dyson Swarm is not necessary to orbit that close to a Star. It could be that the means to capture dark matter is right around the corner, so there's no need to estinguish stars to preserve them. It could be that the means to capture dark energy is also around the corner and there's no need to bother with altering the universe in any way, in fact, it would be a shame to do so. It could be that once a species is advanced enough to transcend its own biology and once it becomes kind of immortal, it no longer reproduces. I'm just pointing out counter arguments, I'm on the opinion that we are completely alone in our Milky Way and most likely the entire Universe. As in there is no bacteria outside our Solar System, anywhere, but there is no way to know yet.
