any one wanna talk black holes. i'm not a professional or anything. i vaguely remember hearing s. hawkin revising his opinion on it saying it wasnt a "worm hole" anymore and that it just destroys all matter and worth nothing else.
i only make my observations, childlike actually, to that of what happens on earth, and why shouldnt it happen in the rest of the universe. why should anything here (goverening law of physics, etc.) be different anywhere else? just like a tornado, or water running down a drain (or that infamous lake that was drained by accident by some guys drilling and all the water drained into the salt mine, i cant remember the name now but a 6 inch hole sucked in a tanker), why wouldnt a black hole be that "event" that punched a hole into another "dimension/galaxy whatever" with less pressure. and maybe all that "dark matter" is the "reminant" of what comes out of a black hole. i dont know, just talking. my head is always "out there, out of earth..." maryalien |

i got the feeling i was out of my league when i replied the first time, but your all so damned interesting, i love this stuff. really.
and i didnt know black holes diminish over time. i read an article saying that they vacillate, periods of "feeding" and dormancy. but naturally it must have its own life cycle, just like everything else and the universe... thank you obe one |

We are most of us professionnal scientists or "enlightened amateurs", so what we often speak of things other people cannot simply understand. Dvandorn was kind enough to explain you some basics, I think it is great. Black holes do not go through periods of activity and dormancy, but, in the center of a galaxy, the activity of the galaxy sends matter at times to the black hole, and at other times it does not. So the black hole is "active" or not, depending on the feeding it receives. But basically it is still here, increasing at each feeding period and never decreasing. Oh, some scientists postulated they decrease, but it is at a scale of time billins and billions times the age of the universe. So practically in astrophysics we consider they do not decrease. An interesting fact is that the smaller a black hole is, the faster it decreases, with more and more energetic radiations. So than when a small black hole ends its life, it produces more and more energy, light, X ray, gamma rays, ending in something very much like a nuclear explosion (although no waste remain). |
