A new study proposes that black holes not only exist in an isolated state, but they also expand along with the universe. The research, carried out by theoretical physicists Valerio Faraoni and Massimiliano Rinaldi, challenges the traditional view that these massive objects are immune to cosmic expansion. Expansion of the universe and black holes The expansion of the universe is a well-documented phenomenon, but the relationship between this expa…
