Once a great dreamer I was of the Cosmos but over time I have found less
dream and more reality binding my thoughts. If I understand correctly, one of the big prize questions in physics, both quantum and astro, is the relationship between atoms (and other subatomic particles) and gravity. I understand the conversation in this thread about how when a black hole forms it doesn't suddenly take on a new and increased amount of gravitational pull on it's surrounding. I also understand the BB analogy in that if you take 100 BB's and it's melted equivalent there is no change in it's mass yet if you take that mass of 100 BB's and crush it into the size of 1 BB it's gravitational effect at the surface of the BB will indeed be much stronger than if it were just 100 BB's in a jar. Radius, mass, and gravity work together but it's important to visualize the relationship as dependent upon where your measurements are being taken. Something I've pondered about concerning black holes in particular, is the organization of the atoms inside. I flounder to produce the name of the researcher who studied the shapes of solids 100's of years ago; the one that concluded that some shapes are inherently natural. I visualize atoms as BB's that are squashable. If you put BB's in a jar you can see that they rest in a certain way naturally. In a black hole, or even all black holes, are the atoms that exist inside organized in such a way? Do atoms even exist inside as we know them or are they completely unbound and crushed further into the various quarks that make up protons and neutrons? Do electrons survive the transformation or are they completely removed from the mass? Is a black hole susceptable to ground -state fluctuations? I ask the questions but expect no answer as they very well might not be valid questions at all and just the musings of an idiot or just more dreams. |

Mark Oliver wrote: The current accepted theory of a black hole is NOT consistent with current accepted physics. [clip] The problem with that argument is that you would ultimately need to justify the validity of the concept, "accepted". Social acceptance, e.g., acceptance by one or many persons as a justification for any scientific claim claim is fallacious. That would be an example of the fallacy of 'primacy of consciousness' rather than of the primacy of existence. What people say, is not scientific justification. Only the facts of existents in the universe pertaining to the subject matter being identified, and logical proof are proper justification. The idea of, "accepted physics," implies a selected or chance number of physicists who presumably would agree on the subject matter being claimed true. The number of such endorsements has nothing to do with the truth of the scientific identifications being claimed. That is the fallacy called, 'ad populem', or the appeal to quantity. In fact some theories could be true, and at the same time no physicists would endorse the theory. Would that mean the theory is false? No. Social metaphysics is no justification for anything whatsoever. The matter of "accepted" physics implies a certain level of quality of claims submitted as well as a group of esteemed, tenured, approved, degreed, licensed, or even, employed physicists who would decide the acceptance of the claims being made. They would determine the social metaphysical 'truth'. That is the fallacy of the 'appeal to authority', and that is no justification for any claim. Simply because one or more famous people approves of a claim or can be used as a reference for any claim does not make that claim true. Lastly, there is the claim that you make in the subject line that there is indeed an agreement between the concept of the BH and what physicists think. That is the fallacy of, 'non-sequitur', meaning that the premises given do not result in in the conclusion stated. You allow the ready to place commonly used notions as the premises for the statement. You have not offered any type of scientific evidence for that claim. My guess is that most physicists are probably highly suspicious for any claim of the existence of, or functioning of, a Black Hole. Again, you provide and explain no evidence. You assert, as if it is an axiomatic truth, that there is in reality an existent that is a Black Hole. You have not justified that. That is just one more 'non-sequitur'. BTW, the correct spelling is, "violates." Use a spell checker on your posts. Ralph Hertle |

The current accepted theory of a black hole is NOT consistent with current accepted physics. Here are the problems; 1) All accepted calculations of gravitational pull are based upon mass and the distance between two objects. It is not based upon the density or dimensions of the same "singular" mass. Thus, when a quasar collapses it is still the same amount of mass, only denser (smaller dimensions). Then why would we assume that its gravitational pull will change, when its mass does not change? Here is proof, measure the mass of 100 steel ball bearings on a scale, then melt all of the steel bearings to a single mass from the 100 smaller bearings. The mass will not change, thus its gravitational pull does not change either. That is a well reasoned argument - one of a type that is exceedingly rare in discussions of science these days. The universal premise that you use is that mass is independent of the shape, or shapes, of the thing, and that the mass is a property of that existent that is the amount of its substance. Mathematics, as a measurement science, can identify and calculate the precise amount of the mass of a particular thing. I would add, that the identification of that type of concept, whereby all the specific properties except for the defining characteristic in a scientific context, as a universal premise, is a fundamental discovery of physics by Archimedes. He clarified for science Aristotle's concept of the defining characteristic of a concept, one that differentiates the discovered concept from all others. Ralph Hertle |

Since quasars are very old (high z = high distance) how so many ultrapowerful black holes could be formed in the early ages of universe? And why we don't have quasars with low z? Now we have a lot of black holes formed in the last 13,7 billion years and some of these black holes could be the power source of new quasars. Or maybe I don't understand a thing of quasars? Luigi Caselli The current model for a quasar is a supermassive black hole at the center of a galaxy (possibly driven to the levels of energy generation we calculate for it for the distance they are determined to be by a collision with another galaxy - based on HST images of distant quasars that show they are at the center of such galaxy collisions). This black hole is being fed by an accretion disk surrounding the black hole, possibly formed from gases and disrupted stars in that region. Quasars are believed to be more common in the early universe simply because galaxies were being constructed at that time through the merger of clouds of newly forming stars and gas (based again on some of the recent images from the HST ultradeep field), so there would be more raw material to feed them. Given time, they would sweep up the material near them and have reduced input from greater distances, reducing the energy output. This takes time, say nearly the current age of the universe, such that the black holes still reside at the center of galaxies, but their feeding frenzy has been greatly reduced. But it also implies the the collision of galaxies which result in material being brought in close proximity to these black holes might fire them up again as additional fuel is made available for a renewed feeding frenzy. As to their existence at this early epoch - likely formed from the merger of star-produced black holes in the crowded environments of the core of galaxies. Massive stars, made mostly of hydrogen, could become more massive than those today polluted with such heavy elements as carbon, iron, silicon, nitrogen (the stuff we are made of). These higher mass stars would evolve even faster than the massive stars formed today (as they are more massive than the current round of stars), allowing them to reach the stage of forming black holes faster and populating the cores of galaxies at the time those galaxies were forming. Hope that helps (though it is not a complete scenario by any stretch). |

The current accepted theory of a black hole is NOT consistent with current accepted physics. Here are the problems; Actually, it looks like your misunderstanding of what a black hole is and is not is not consistent with both accepted laws of physics, and the accepted model of a black hole. 1) All accepted calculations of gravitational pull are based upon mass and the distance between two objects. It is not based upon the density or dimensions of the same "singular" mass. Thus, when a quasar collapses it is still the same amount of mass, only denser (smaller dimensions). Then why would we assume that its gravitational pull will change, when its mass does not change? Here is proof, measure the mass of 100 steel ball bearings on a scale, then melt all of the steel bearings to a single mass from the 100 smaller bearings. The mass will not change, thus its gravitational pull does not change either. Absolutely correct. But since black holes are not purported to have stronger gravity than any other object of the same mass, what does it have to do with your contention above? A black hole with a mass of one million suns does not have a stronger gravitational pull than one million suns. It has exactly the same pull. But a the black hole in question has the mass of one million suns in a relatively tiny volume (mathematically, it's treated as a dimensionless volume, a singularity - in reality, we may never know). If you were to collapse our sun into a black-hole-sized volume, it would be a black hole (I'm not certain, but I think the earth's mass would also be sufficient, if you could get it down to that size). The reason the sun isn't a black hole at its current volume is because the event horizon for a black hole of solar mass is smaller than the sun's radius. That is, by the time you get close enough to make the field strength large enough to prevent the escape of light, you're below the surface of the sun. If you were to head directly towards the center of the sun, you would experience a steadily increasing gravitational field. As soon as you hit the surface, the field strength would begin dropping, because more and more of the mass is being left behind you. By the time you get to the center, you have a net field strength of zero, since all of the mass is (roughly) distributed equally around you, pulling equally in opposite directions. The tidal forces would be pretty extreme in practice, of course, since different bits of your body would be closer to different amounts of mass. It would be a bit warm as well. The maximum field strength is at the solar surface, and at that distance from the center of mass, light can escape. Only by shrinking the volume can you ever get closer to the center of that same solar mass. 2) A black hole would be a self-feeding energy force, and grow at such a fast rate, it would swallow the entire Universe at an accelerated rate. Nonsense, because a black hole is no attractive on large scales than its mass equivalent in other forms. A supermassive black hole of many million solar masses is still pulling with a tiny fraction of the force of a whole galaxy, when measured from the same distance. This is an economic concept of a compounded gain. If you save a dollar, you also didn't spend a dollar, thus your theoretical gain is 2, not just 1. The same idea applies to a black hole, as it pulls matter and energy to its surface, its mass and subsequent gravity would increase. Thus its gravitational pull would reach further and further, pulling in more and more mass, this would become a self-fulfilling cycle until it pulled in the entire mass of the Universe. If matter weren't in motion, and the universe weren't expanding, this would be true of the gravitational center of the universe, not any black hole. That is, a static universe (no initial movement, no expansion) would collapse to the point one would calculate as its gravitational center (given the information required to calculate it, which we certainly don't have). But that's not our universe, and even if it were, black holes would figure in the calculation of gravitational center exactly the same as normal stars of the same mass, as well as diffuse gas and dust of the same mass. NEW BLACK HOLE THEORY - a black hole is a region of space that has been perfectly balanced, as matter and energy are separated to singular values when a quasar expels its nuclear fuel. Matter and energy are different manifestations of the same, thus as energy is released, matter no longer exists. Therefore, since force and inverse square resistance are now perfectly balanced (1=1 squared), this is a highly resistive region of space that light cannot penetrate, as there is no distinction between force and resistance. We observe this space as a vacuum, as force and resistance begin to balance, yet in reality they negate each other, and become ambiguous. This is the same effect as in noise cancellation. When force and resistance become equals, a black hole is formed, and since light is energy, it cannot penetrate this highly resistive region of space. Therefore, a black hole is indeed just a black hole, where nothing can exist distinctly, not even light energy. This is not a theory. It is incoherent babble, where words are used without respect to their accepted meanings. -- - Mike Remove 'spambegone.net' and reverse to send e-mail. |
