New Paper Says Black Holes Could Be as Large as an Entire Galaxy – Futurism
“Dynamical arguments suggest that the maximum mass for a SLAB in our Universe is 100 billion billion solar masses, with a size comparable to that of the galaxy.”…

Galaxy Size
Step aside, supermassive black holes scientists say that there could be black holes the size of an entire galaxy.
The supermassive black holes go up to nearly 100 billion solar masses, Queen Mary University of London astronomer Bernard Carr, who worked on the new research, told Futurism. If we define a SLAB to be larger than this, then its radius must be at least the size of the solar system (around a hundredth of a light-year). Dynamical arguments suggest that the maximum mass for a…
