Blackholes Don't Tilt
Blackholes spin slower with time. Electrons can't spin slower than "C"
When a blackhole stops spinning it will explode. Without its feature of spin there is no electron. (that's the way of reality) Bert |

writes "G=EMC^2 Glazier" wrote in message ... BV What happens when a BH takes in every thing around it? It still has the micro waves of space(endless supply),and as its mass density goes up it gets colder. Bert Surely a BH gobbling up a bunch of stars will have some change as all the stars in the area are gobbled, and there is nothing left by the background xrays? Does it slow down? Does it begin to lose gravity? I'd guess it will just sit there when the area is empty, forming the sort of cold spot Bert hopes to see. Trouble is, the centre of a galaxy is a very crowded place, and stars are probably being perturbed and changing their orbits all the time. Eventually, one will pass close enough for a collision and you'll get another outburst of energy and matter that's moving too fast to be pulled in. And the BH is always getting bigger. Unlike the tiny ones that are theorised it doesn't produce much Hawking radiation (that's why it's so cold) -- "Roads in space for rockets to travel....four-dimensional roads, curving with relativity" Mail to jsilverlight AT merseia.fsnet.co.uk is welcome.

BV The blackhole's great mass density gives it a great gravity
force,however gravity weakens inversely the square of the distance between objects. Stars orbiting a blackhole have angular motion,and like the earth orbiting the sun can have a stable orbit. Stars that have fallen into a BH give the BH at the core a mass of millions suns . I don't have any idea how many stars make up our galaxy bulge(its real bright.) We have to keep in mind that the BH does not add any light to the bulge,it just helps to create it. Bert |

BV Space has energy,and a blackhole all by itself might not be as
massive as a blackhole at the core of galaxies,but the micro waves intrinsic to all of space can add to its mass. A good theory on blackholes could go like this. "blackholes transform energy waves into particles" (mass) We know there are vast areas of space that are empty. Astronomers call them "space voids" This could be a cluster,or strings of blackholes. A theory could have this idea"Blackholes made space clumpy" If we someday find space voids colder than the space around them that also could be telling us about loner blackholes. BV there has to be billions of blackholes that are not absorbing a star that got to close. Blackholes were formed at the big bang. Blackholes were created by the first stars(supernova). Blackholes have to be very long lasting(very stable) I can't visualize and inner structure motion. Bert |

... Bert, I understand all that. We have already discussed that. Maybe I need to re-phrased my question. When a BH is sitting around gobbling up stars, it is adding massive amounts of mass to itself. When the stars are all gobbled up, and there are just small snacks, the x-rays, to gobble, how does this affect the BH? Can a BH fizzle out? If it's mass stays nearly the same, can it eventually just cave in on itself? Starve? A large, hence cold, black hole can't help but keep feeding on background radiation. Even the 2.7K CMBR is enough to continue to add mass to the BH, albeit very slowly. Eventually, if the universe heads towards a heat-death and the CMBR drops below the temperature of the BH, then the BH will begin to evaporate. The evaporation process would take many, many, many, (well, you get the picture), trillions of years. |

BV Rodger Penrose has a singularity in the core of every blackhole.
What you are really asking does a very massive blackhole lets say a mass of 100,billion suns,Have a credical mass? I say yes(based on nothing)but I like continuing mini bangs created by an exploding blackhole to create a mini universe. BV it kind of makes sense to me to have very large mass blackholes(like those in galatic cores) fuse together(collide) because nature likes to do things using pairs. This could almost instantly create the credical mass. It could be happening as I type ,and our gamma ray detectors pick up their explosion every day. We might say some day " Here comes another universe " Bert |

Hi Scott What you posted is a good theory on early blackholes that
came out of the big bang. The reason is things were closer together(more dense),and blackholes could have gobbled up mass that was well within its gravity field,and this made its gravity stronger. Could we theorize Scott that these early massive blackholes,are what we see as the core(hub) of galaxies? If I was a blackhole I would love to be in that bright bulge of our galaxy. Fact is I can't think of a better place in all the rest of the universe. Bert |

Mason It is our fault for not thinking harder. I have a very
good theory why galaxy's created 100 billion stars in set areas of space. Bert |

in message ... "Painius" wrote in message ... Not so mysterious, BV... here on Earth, as on any mass, "down" would be in the direction of the flow of gravity. And "up" is the opposite direction. And on an even *more* arbitrary note, astronomers like to view the Solar System as having a "top" and "bottom." If viewed with the planets revolving around the Sun in a counter-clockwise direction, we are viewing the "tops" of the planets (in most cases) and their North poles. So in this case, if one looks out into the cosmos from, say, Antarctica, then one is looking "down." snip So where would the arbitrary point for BH's be set? BV. Up and down having already been standardized as previously noted... if you are looking at a BH from a point along its spin axis, and if it is spinning ccw, then you are looking at the top of the BH. And this makes me wonder what the Universe looks like from *inside* a BH? How do the stars appear? Is their light maybe distorted by the tremendous BH gravity field? Is starlight bent in weird and beautiful ways? happy days and... starry starry nights! -- Asimov! where have you gone?
