There is in fact a minimum mass for a black hole. That's called the Plank Mass, which is the amount of mass that forms a Black Hole with a size of 1 plank length. This is also the maximum mass of an elementary point particle.
- mhh__ 6y agoIf you can show that there's probably a nobel prize waiting for you
- pdonis 6y ago> There is in fact a minimum mass for a black hole. That's called the Plank Mass This is a speculative hypothesis at this point, since we do not have a good theory of quantum gravity. A lot of physicists think it will turn out to be true once we do have a good theory of quantum gravity, but it's still a speculative hypothesis at this point. > This is also the maximum mass of an elementary point particle. This is part of the same speculative hypothesis.
- wnoise 6y agoThere is no reason beyond numerology to believe that any of the Planck units actually mean anything.
- dogma1138 6y agoPlank Units represent physical constants, they are there to make equations and more importantly hypotheses/predictions continue to work in a world where measurements can be constantly refined. Hence they their actual SI values have quite a bit over the years. This is also why Plank units aren’t used much outside of theoretical physics and cosmology which are fields where using absolute value based on current measurements won’t mean that much.
- Dylan16807 6y agoYeah, okay, but we're talking about stellar objects. In that context, there is no minimum mass for a black hole. If you can figure out a way to cram the mass together. But that was the point of the first comment anyway, that if you didn't quite get enough mass+density that you might get something weird.
