what is black hole made out of and what does a black hole "experience"?

[Tim_Lou]

black hole attract all sort of matter or non-matters and suck them in.
does it ever end?

it keeps compressing the matter and decreasing its volume.... is there a limit to it?

and what happens to the matter inside a blackhole? does it stays there, disappear and becomes non-existence, or goes into different dimensions? does the gravitional field of a blackhole increases, decreases or remains constant over time (well.. its probably an increase)?

how is matter gonna react to such extreme time dilation and space-time curvature?

yes, the gravitational field of the blackhole should increase because the more it "sucks" in, the more dense it's going to be and the more curved the space will be, therefore the gravitational field will become greater.

I think matter is going to get all crumpled up and then ripped apart into millions of pieces, into particles.

Remember, mass is energy. Energy is information. e.g. a photon is a matrix of info RE the energy it consists of.

There was just a major change in the theory of this Information RE a Black Hole. Hawking, the leading expert of Black Holes, just changed his 30 year stance on them. He had contended that the information of the mass absurbed was lost. But now:

"Hawking Loses Bet; Changes Mind on Black Holes ... A black hole only appears to form but later opens up and releases information about what fell inside. So we can be sure of the past and predict the future."

More likely the particles are ripped apart and converted into energy.

hehe, thats pretty recent news.
however, where would the stuffs in the blackhole be in between the time when it got sucked and the time when it gets released? in between dimensions?

"More likely the particles are ripped apart and converted into energy."
so, particles collide and energy is released? hmm... but none of the stuffs would be able to escape...so, will the energy change into matter and then back into energy again?

if the mass all changes to energy and escape, and if the rate that it sux in matter is lower than the energy that escapes, the blackhole would be destroyed?

what about time dilation? isnt that the "local time" would be zero once got into the black hole due to the extreme gravitional pull?

[Aki]

I don't think time even exists inside the black hole, am I right?

The problem with Black Holes is that the rules of physics break down within them. So who really knows? At the surface of the singularity (the point at which there is no going back) time dilation is infinite. But is time infinite? if it is then total time experienced at that point = infinity/infinity = any number. How time behaves beyond that point is anybody's guess.

Frankly I am not a believer. The maths involved requires Gravity to have properties that disobey conservation of mass/energy in normal space. I am not saying that a Black Hole can't exist, but I will say they can't be created.

I know that they're creating baby black holes in labs that lasts for a few seconds, but how are they going to do any goods on the research?

Since I'm no expert on black holes I'll answer only this bit.

The answer is "yes", and it's quite obvious (from your question). If you put less in than what goes out then the black hole evaporates.

Blame: You question whether black holes can form. If they exist, wll, then they must have formed somehow. Black holes are the remains of dying stars.

Here is some info, although it was written long before Hawking retracted his "non-evaporation" theory, so the "nothing escapes" bit is now obviously being questioned.

Aki.

Err, No.

Nobody has created a black hole. Certainly not one that lasted seconds.

Tormod.

If they exist, you are perhaps right. The one quibble would be that of a Black Hole formed outside the area in which our laws of physics operates. Say before the universe receive its present laws, or transferred from another universe with different laws.

However I do not expect that there are any. My argument was perhaps not clearly made. What I mean is that the laws of physics may allow a black hole to exist, if it could be formed. However, as it can't be, there are none.

I know that Hawking would not agree with my stand, nor for that mater Einstein, but as I have stated before, I have slightly different beliefs regarding the nature of Gravity. While Einstein would have Gravity as a warping of space, I would have it as a dilation of time, with that being equivalent to a reduction in C.

As to Black Holes being the remains of dying stars, in my view it doesn't happen. You just get a wider range of neutron stars.
