I stumbled today upon an article where it was said that a black hole created out of matter would be no different from one made by antimatter. And it got me thinking. As far as I know, scientists are still wondering what caused that fact that although at the beginning of the universe matter and antimatter was 50/50, what we observe in the universe is mostly matter and not anti-matter. Maybe antimatter has some characteristics (unknown to me, perhaps known to you) that would cause it to be more prone to creating black holes, and the matter/antimatter imbalance could be explained by the fact that the missing part of antimatter contributed to creation of black holes. And even if the very nature of antimatter does not cause any such "preference", maybe there are othere explanations to why black holes would "use up" more antimatter.
Just an idea though, I wouldn't be surprised if someone had it before me, but quick google search returned nothing on the topic, so I thought that maybe I might provide some food for thought to somebody.
Would anyone care to comment on that idea? Or point me in direction of some reading on that topic?
