Snapshots of the Simulations (IMAGE) National Institutes of Natural Sciences Caption Snapshots of the simulations showing the distribution of matter in the Universe at the time of black hole formation (top) and the density distribution of black hole-producing gas clouds (bottom). In the bottom panel, the black dots near the center of the figure represent massive stars, which are thought to evolve into a black hole in time. The white dots represent stars that are smaller than 10 solar mass and were formed by the fragmentation of the gas cloud. Many of the smaller stars merge with the supermassive stars at the center, allowing the massive stars to grow efficiently.
