The article fails to explain why this event challenges our understanding of black holes. Did we expect such big masses to spiral for much longer or something? Why was this collision supposed to stay unstable?
- MattPalmer1086 1y agoThere just isn't a way to make black holes that big from the collapse of stars when they go supernova. So maybe both of these black holes formed from earlier mergers of smaller black holes. Or maybe there are other ways to make larger black holes we don't know about. They are in a range of mass we don't really expect to see theoretically.
