WATCH | Simulation of binary black holes merging:Now to the final 142 solar-mass black hole. The second is that multiple black holes could have merged within a dense star cluster, creating larger black holes of differing masses. The black hole created by the merger falls into a category known as an intermediate-mass black hole — and is the first clear detection of a black hole of this type. While the discovery is a first, the astronomers know that they need to increase their sample size to adequately explain the existence of intermediate-mass black holes. So, more mergers that yield intermediate-mass black holes will help us to understand ... how they're formed," Goetz said.
