Mr Hawking has famously said that Black holes can dissappear ? into nothing ?.
but what about the mass? what are your opinions? has the black hole moved into another universe by pushing its self into another dimension or popped into the past or future or jumped to another part of the universe or has the mass just gone poof!!!! |

How can you know about it without knowing even the first thing
about it? There are probably hundreds of different websites which explain Hawking's theory regarding evaporation of black holes, plus existing threads discussing it on BAUT and other forums. And, if all else fails, you can get a copy of Hawking's ridiculously popular book, 'A Brief History of Time', and read what he had to say about it in his own words. -- Jeff, in Minneapolis

I agree with you Antoniseb. I can not see how the mass that might be converted to energy in the singularity, BH., could melt away, leak out or, other wise dissolve the BH., Its like the idea of the universe not being infinite. The detectable universe might be 13.7 billion LY from us. We are told this might be expanding at an ever faster rate that could prohibit us ever seeing it. What stops there being others. Much farther away doing the same thing. We will not see them until the distance between us is less than the time its image might take to reach us. Its like asking your speed in space. You can not answer these questions. Because there is no reference point. Nothing in space is still ( motion less ). If some thing is coming straight at us at a speed greater than its light image can travel. We will not know it is here till its been. Do not attempt to make to much of my ramblings. I have just confused myself. . . .

Yes you are right I dont know anything at all about Black holes or what happens to them when they dissappear all I know is that most people in the know don't agree with him ,I'm just interested in what your opinion is ? .I can only guess (what is wrong in that) i.e if matter can't be distroyed then the black hole can't just dissappear into nothing can it . this is logical isn't it ,I dont have to be bright as you to know that ,,,, my uneducated guess is that it must be somewhere else ,,, blackholes are associated with time travel i.e if you travel around one of them you can go back in time ,dont make me explain it (i'm thick) if the black hole collapes in on its self spining faster than light could it act as a time machine ? (i dont know ) and I can only count to three so I can't do the Math ,,,but the matter isnt there or where the black hole was .i am awear that some black holes throw back out the matter they consume , I'm not talking about those ,becauce we know where the matter is .

A test of Hawking's theory is that there should have been BH's formed at the beginning(?) of the universe wherein there has been enough time for them to evaporate to a small enough size that exponential decay occurs and a massive explosion results that would have a charecteristic energy spectrum. This has not been observed (?) yet(?).

Actually the mass that escapes a black hole by Hawking radiation is in the form of energy; small holes effectively radiate very energetic photons as if they were very hot. This radiation escapes at the speed of light.
Energy is of course equivalent to mass, so the hole loses mass. Larger black holes are effectively cooler, and radiate less energy. |

I agree with the possibilty but nothing firm yet(?) And while I'm at it I thought it was particle ant_particle production at the event horizon wherein one was captured and one escaped which could still be seen as a photon if it was the anti-particle that escaped and subsqently annihlated.

That is the way it is often described, yes, but I think that description is a little over simplified to be realistic.
Have a look at this page which explains it a little more technically. http://math.ucr.edu/home/baez/physic...s/hawking.html And no, I don't really understand this description myself... |
