Is a Black hole as big as Sun. Or it is as small as a Moon. Or just
the size of a FootBall. Does a Black hole has a mass. And does it also have gravity. And Is it as hot as Sun or very cool. I heard Gravity is because a few elementary particle muon/photon (Gravitons) are exchanged between mass. In that case how these gravitons are able to go outside the Black hole? As I heard Black holes even Light can not escape from it. What are Gravitons and do they travel at speed of Light. What is the mass & charge of Graviton? If a Mass gives out Graviton then I think slowly it should loose Mass. Does every particle having mass gives out Gravitons??? Bye Sanny Play Chess at: http://www.GetClub.com/Chess.html |

Bye Sanny Play Chess at: http://www.GetClub.com/Chess.html Black holes can come in different sizes depending on the conditions that resulted in their formation (particularly its mass when it was a big star). There is work right now to create mini-black holes in large hadron colliders. http://www.csmonitor.com/2003/0523/p25s02-stss.html |

Dear Sanny:
"Sanny" wrote in message ... Is a Black hole as big as Sun. Or it is as small as a Moon. Or just the size of a FootBall. It depends on the mass it has. If the Earth were compressed into a black hole, it would be about an inch in diameter. And 6300+ km away, it still would yield a "gravitational acceleration" of 9.81 m/sec^2. Does a Black hole has a mass. And does it also have gravity. And Is it as hot as Sun or very cool. Yes it has mass, and the mass produces gravitation. The mass establishes the black hole's temperature. More mass = cooler. The earth-mass black hole above is still barely above absolute zero (still accepting mass from CMBR radiation). A toaster-mass black hole would be much hotter, evaporating ina short time. I heard Gravity is because a few elementary particle muon/photon (Gravitons) are exchanged between mass. In that case how these gravitons are able to go outside the Black hole? As I heard Black holes even Light can not escape from it. Gravitons are "virtual exchange particles". Just like the "virtual photons" that produce the effect we call charge, they travel at all possible speeds (no c limit), and all possible paths. See gravitons are part of quantum mechanics, and are blind to either distance or time. What are Gravitons and do they travel at speed of Light. Both faster and slower. What is the mass & charge of Graviton? Mass is expected to be very large last I heard. Charge is zero. If a Mass gives out Graviton then I think slowly it should loose Mass. Does every particle having mass gives out Gravitons??? "Exchange" is they key word here. What it gives out, it gets back. Now for some links that you could read... http://en.wikipedia.org/wiki/Black_hole http://en.wikipedia.org/wiki/Hawking_radiation (temperature) http://en.wikipedia.org/wiki/Graviton David A. Smith |

What is the mass & charge of Graviton?
Mass is expected to be very large last I heard. *Charge is zero. In that case Say there is a Particle smaller than an electron. And it gives out a Graviton, So Graviton must be lighter than electron mass. So Lightest particle X Then it exchanges a graviton. In case it is throwing out a graviton Its mass must be greater than Graviton. Else we will violate "Conservation of Mass Principle." And I do not understand What is the shape of Graviton. How it is exchanged? Incase it is exchanged how that creates an attraction? Gravitons are "virtual exchange particles". Just like the "virtual photons" that produce the effect we call charge, they travel at all possible speeds (no c limit), and all possible paths. See gravitons are part of quantum mechanics, and are blind to either distance or time. Say 2 Mass are 1 lightyear apart how much time it will take for the gravitons to reach from one mass to other. Do each mass throws Graviton in all Direction? Say an electron is throwing Graviton in all directions. At what time interval these gravitons will be thrown? And if an electron is throwing 1000s of gravitons in each direction how will "Conservation of Mass Principle." Mantained? Bye Sanny Play Chess at: http://www.GetClub.com/Chess.html |

Dear Sanny:
"Sanny" wrote in message ... What is the mass & charge of Graviton? Mass is expected to be very large last I heard. Charge is zero. In that case Say there is a Particle smaller than an electron. Electrons are point particles. Nothing smaller. But you mean "less massive". Neutrinos are much less massive. And it gives out a Graviton, So Graviton must be lighter than electron mass. Actually I believe the graviton mass is larger than the mass of most molecules. So Lightest particle X Then it exchanges a graviton. In case it is throwing out a graviton Its mass must be greater than Graviton. Else we will violate "Conservation of Mass Principle." Conservation of mass has been discredited. Since it is an exchange, it occurs in essentially zero time, and the world at large is none the wiser. And I do not understand What is the shape of Graviton. It is shaped like a unicorn, since it is only theoretical, and has never been observed. Do not strain at this, it is a waste of your time. How it is exchanged? In case it is exchanged how that creates an attraction? What do you mean "how is it exchanged"? It was invented to be "that which can merge continuous spacetime with the quantum realm". That it *is* exchanged is a given, because we can see gravitation at work all around us. Gravitons are "virtual exchange particles". Just like the "virtual photons" that produce the effect we call charge, they travel at all possible speeds (no c limit), and all possible paths. See gravitons are part of quantum mechanics, and are blind to either distance or time. Say 2 Mass are 1 lightyear apart how much time it will take for the gravitons to reach from one mass to other. Do each mass throws Graviton in all Direction? Zero time, just as in GR. No, exchange particles have unique, known source-destination. Say an electron is throwing Graviton in all directions. At what time interval these gravitons will be thrown? Not thrown in all "directions", thrown to all members of the Universe. Thrown continuously. And if an electron is throwing 1000s of gravitons in each direction how will "Conservation of Mass Principle." Mantained? "Conservation of mass" is not a law. Exchange is "round trip". This is not worth you straining over, unless you want to learn the underlying physics. Did you read the links I posted before? David A. Smith |

The Schwarzschild radius r of a black hole is given by r = 2GM/c^2 where G is Newton's gravitational constant 6.67 * 10^-11 m^3 / (s^2 * kg), M is the mass of the black hole, and c is the speed of light, 3 * 10^8 m/s. Look up some masses and plug them in. This isn't really the distance to the center of the black hole, which is not well defined, but 2 pi r and 4 pi r^2 give you the circumference and surface area of the black hole. Does a Black hole has a mass. And does it also have gravity. And Is it as hot as Sun or very cool. They have mass and gravity. Matter falling into a black hole will get much hotter than the sun, but if a black hole had nothing falling into it, the only radiation coming out would be Hawking radiation, which is extremely faint for typical-sized black holes, and therefore extremely cool. I heard Gravity is because a few elementary particle muon/photon (Gravitons) are exchanged between mass. Gravitons are not muons or photons. They are a hypothetical new undiscovered particle. In that case how these gravitons are able to go outside the Black hole? As I heard Black holes even Light can not escape from it. See the FAQ: http://math.ucr.edu/home/baez/physic...k_gravity.html What are Gravitons and do they travel at speed of Light. What is the mass & charge of Graviton? If they exist, gravitons have zero mass, zero charge, and spin 2. Because they have zero mass, the gravitons in gravitational waves travel at the speed of light. But the gravity that holds you to your chair would be a quantum-mechanical effect, and there if you want to look at things in terms of the trajectory of the exchanged particle, you'd have to do a sum over all trajectories, including ones not at the speed of light. If a Mass gives out Graviton then I think slowly it should loose Mass. Not if the gravitons exchanged transferred momentum but no energy. Does every particle having mass gives out Gravitons??? Even particles without mass can absorb and emit gravitons. -- Jim E.

The close analogy between the Principle of General Covariance and Gauge invariance, allows us to investigate the gravitoelectromagnetic properties of quantum materials in the framework of massive gravitoelectromagnetic Proca equations. We find that the breaking of the PGC in superconductors leads to a gravitomagnetic London moment and an associated additional gravito-magnetic term in the Cooper pairs canonical momentum, which can explain the anomalous excess of mass of Cooper pairs reported by Tate. The breaking of the PGC in superconductors implies the non-equivalence between a rigid reference frame made with superconductive walls (super-conductive cavity), being uniformly accelerated in a gravitational field free region. (28) (29) and a classical rigid reference frame (made with normal matter) in a similar situation. (30) However breaking the principle of general covariance leads to a violation of the law of conservation of energy-momentum. It is not clear yet if this would be a sign for some manifestation of dark energy in superconductive materials. However it worths further investigation. --Clovis de Matos http://arxiv.org/abs/gr-qc/0607004 Sue... [...] |
