The Natural Dispersion of Black Holes

  1. Sep 8, 2011 #1
    Black holes are believed to be scattered throughout the universe. These ultra-dense bodies have a gravity field so dense that nothing, not even light can escape. If these bodies are able to consume everything that enters its event horizon than over the billions of years that the universe has been in existence there should be several hundred black holes that have grown so large that vast regions of the universe should look like black voids on hubble telescope images. Since everything in the universe is moving black holes should be continuously growing. Growing to a point where entire galaxies are quickly consumed and eventually the entire universe.

    My question is, do black holes grow to a point that they actually fall apart.

    When a super giant collapses could that the collapse is so violent that all atoms are actually crushed to where there is on electron movement? If so, I believe that it would release all the energy that keeps electrons in their orbits and therefore leave the black hole at a temperature of absolute zero. As stellar material is consumed the energy of that material impacting the surface transfers that energy. Not having been at the original violent collapse, the newly arriving material isn’t crushed (at the atomic level) and continues to transfer small amounts of energy to the core. A black hole continues to grow until it reaches a point where the material that it has consumed has transferred enough energy to allow the atoms within the core body to actually rise above absolute zero and that is when the body begins to fall apart. While the gravity is still immense but when the atoms receive enough energy to start moving again even the gravity can’t keep the electrons pressed against the nucleus. As these atoms regain their energy level it allows for more energy to be transferred to the rest of the core until it is a very dense cloud of atoms that will eventually form a cloud that begins to form new stars. (the stellar cycle of life)

    A partial answer to your questions. At the center of galaxies there are black holes with masses of several million suns or even billions. However, they don't take up a lot of volume, since the Schwarzschild radius is proportional to the mass.
    The following from Wikipedia gives the mass and size ranges.
    Supermassive black hole ~105–109 MSun ~0.001–10 AU

    Black holes are continuously growing, but entire galaxies are not quickly consumed because they are so large. Matter must come near enough to a black hole AND loose enough angular momentum (through collisions) to fall in. Galaxies are so huge that most of the matter never gets anywhere near the massive black hole at its center, and even if they did, most objects have enough momentum to orbit around the black hole instead of falling right in. It's the same reason all the planets in our solar system are still orbiting and did not fall into the sun years ago.

    They don't fall apart because they get too big, if that is what you are thinking (like how certain atomic isotopes are so big that they fall apart quickly). They can evaporate over time though due to Hawking radiation.

    It sounds like you are thinking of blacks holes as curtains, behind which physics goes on as normal (atoms interact, etc.). We don't really know what goes on inside black holes (that's kind of the point of them being black), but the physics at the edge of a black hole would suggest that whatever is going on inside is far from normal. I doubt there are regular atoms surviving bouncing around in black holes.
