Description
From Feb 21, 2024. One of the unexpected realities of JWST is the discovery that we have really been asking the wrong questions in many astronomy areas. For instance: we generally asked how supermassive black holes and galaxies formed, with a basic assumption that these things happened in some interrelated process. We thought stellar mass black holes came from stars and that there might have been tiny primordial black holes that evaporated away, but that was it. Closed case. Black holes formed with all the normal structures we experience today. Except that now, JWST’s observations require us to find a way to accelerate the formation of those structures, and one way to do that is to seed the universe with black holes.
