I see, hear, and read about black holes and their consumption power often. They grow as they consume. Eventually, as they keep growing and consuming, wouldn’t they combine and continue the process until they become so large as to devour everything in existence?
In: Physics
Black holes are really powerful but really really small. A black hole the mass of the sun, for instance, is roughly the size of a city. They’ll gobble up anything that’s really close to them, but things in space are usually really far apart, usually farther away than the danger zone of a black hole. What’s more, they’re very messy eaters, with a lot of their meals getting shot out along their axis of rotation.
All in all, even if it does happen, it won’t be for many zillions (that’s an exact figure) of years.
