Rogue black hole in Milky Way galaxy in an artist

“Rogue black holes” do not have to be “villainous” or “black holes”

When a star dies 20 times more massive than our Sun, it can explode in a supernova and squeeze back into a dense black hole (with the help of gravity). But this explosion is never perfectly symmetrical, so sometimes the resulting black holes crash into space. These wandering objects are often called “villainous black holes” …
