Very simple reason for no black hole

If general relativity is valid, there is no way for an outside observer to tell what fell into the black hole. Most of the information of what went into the black hole is lost. Some information is left after an object falls into a black hole which relates to conservation laws. For instance, a black hole can hold an electric charge. A black hole can hold angular momentum. A black hole can hold linear momentum. A black hole can hold total energy. Since these are preserved by conservation laws, they can be determined by an outside observer after the object has fallen into the black hole. There is no conservation law for dark matter or light matter. Therefore, there is no way an outside observer can tell whether dark matter, light matter or plain light fell into the black hole. Hence, there can be no dark matter black hole. The qualifier is if general relativity is true. If you know of an alternative theory, which permits the existence of a "dark matter black hole," then you should mention it. However, you shouldn't take it for granted that the existence of dark matter implies the existence of dark matter black holes. |

Newton #1: An object in motion tends to stay in motion, unless acted on by an outside force. Therefore, an object can be moving at any velocity even if there was no gravity. * * *Gravitational acceleration would be in the units of km/sec^2, not km/sec. One can not compare an acceleration to a velocity, since they are in different units. * * * There is such a thing as escape velocity. That is the minimum velocity necessary to leave the surface without coming back in the absence of any force other than gravity. However, it is not uniquely determined by the surface acceleration. It is determined by the gravitational potential. * * Escape velocity can be compared to c, since they are in the same units. Both escape velocity and c can be expressed in units of km/sec. So, how much surface gravity as referenced in km/sec/sec does it take to keep photons from exiting? |

Mitchell Raemsch there is no reason at all to assume that one can extrapolate the know laws of physics ad infinitum and end up with a singularity. At the centre of a black hole there could exist quite a large dense object and there is absolutely no way of knowing how big. We cannot see into a black hole neither can we test the laws of physics in the extreme conditions involved. Physics has become the playground of mathematicians and the boundaries between science and recreational mathematics has become blurred. Why can't there be black dwarfs? (spent neutron stars?) Why can't the universe be considerably older or recycled? |

Why not, or perhaps just too much gravitational redshift? As far as anyone knows, the actual surface or neutronsphere of a neutron star can't be seen because of its enormous gravitational redshift, whereas a 1 Ms white dwarf photosphere can be detected because of its limited 3430 km/sec/sec of gravitational redshift simply isn't sufficient to keep photons from getting away.. Isn't the main sequence of a 100+ Ms star going to happen quickly enough? http://translate.google.com/# Brad Guth, Brad_Guth, Brad.Guth, BradGuth, BG / “Guth Usenet” |
