“Stupendously large black holes ruled out as major dark matter component, study finds” — what this page in the network covers. Stupendously large black holes — objects more massive than entire galaxies — are not a major component of dark matter, according to a new study. The research, published in Physical Review Letters, examines the role these hypothetical black holes might play in the universe's missing mass. Dark matter is thought to make up about 85% of all matter, but its identity remains unknown.
The findings narrow the possibilities for what dark matter could be, ruling out a class of candidates that had gained attention in recent years. By analyzing data from the cosmic microwave background and galaxy surveys, the team found that stupendously large black holes could account for at most a small fraction of dark matter.
