there is a lot of discussion about dark matter. Can black holes be used to explain this missing mass of the universe??
Thank u sir, for ur response..No. Dark matter mainly explains why galaxis don't drift apart because of their rotation. Galaxis are surrounded by halos of dark matter, whereas black holes can be found at their centers. For more information there are a lot of threads about dark matter here on PF. Some can be found at the bottom of this page under "Similar Discussions" and even more, if you use the search mechanism at the top right.
