massive black hole? Kevin: No.... (supermassive) black holes live at the centers of galaxies. This is because galaxies are MUCH more massive, so the black holes just fall to their centers. sagex90: At the end of the universe, Say when everything is supposed to rip appart, wouldn't that mean that black holes would lose most of their gravitational pull and thus emit more matter into the universe causing more matter to have more gravitational attraction over a larger area making it so that instead of accelerating out, it would stop somewhere and slowly start falling in on itself again? riyanatarajan: Actually the ultimate fate of our Universe (which is expanding and accelerating) is that will be a cold, lonely place. Existing black holes will not get ripped part, they simply wont be able to grow as they will not be able to capture huge amounts of gas... Janus: I don't mean in the center of one galaxy, rather the way a planet rotates around a star Kevin: Sure... no there is no such case. Such a black hole would have to be even more massive than a galaxy but as far as we know there is no such black hole. Thomaspoke: Close to what hunnylover2's answer was, does that mean that a black hole isn't like a tunnel, it is more of a puncture? Ezequiel: That's a good way to see it... matter "bends" the space time around it. You can image that at the center of the black hole
