Got it. Dragon's Egg is a great book by the way. I recommend it if you haven't already read it.Good science fiction that incorporates small black holes normally treats them as products of advanced technology. There is no fundamental limit on what mass a black hole can be, it's just that we don't know of any natural process that isn't driven by gravitational collapse, and that requires a few solar masses.Ok. Why does it seem that all the really cool ideas are prohibited (or at least wildly unlikely) given the currently known mechanisms?
While there is some (largely untested) theory regarding the possibility of tiny primordial black holes, created in the earliest stages of the evolution of the Universe, there is no known mechanism for generating black holes with a mass less than about three suns.
PS - The novel Dragon's Egg by Robert L. Forward has a plot point involving a few small black holes inside the Sun that are removed by the helpful Cheela!
