Thanks for sharing. Hawking rules.

Time is a man made measurement, Time is distance times speed the only thing that could stop time and light is a black hole.

I read the book.

black hole is hell

@GShock112 Thermodynamics demand that Info escapes from the Black Hole, yet it has an attraction that is greater than that of speed of light, thus nothing can escape from it once the Event Horizon is crossed, some people have tried to explain how physical information could espace a black hole through quantun gravity and string theory, but you wrong in one thing, Black Holes desintegrate because they have so much density they crush their very own mass, thus erradicating their own density.

@finemofok time could stop if everything cooled down to absolute zero. Than there would be no movement (speed)

@GShock112 I don't really know how to explain it because I haven't taken any general relativity or quantum mechanics classes yet, but the consensus among physicists appears to be that black holes evaporate.

@jaimesthesaint

Even if a particle escaped, it would escape the gravitational attaction because of magnetism and because of angular speed but these things can only happen OUTSIDE the black hole. For nothing, literally nothing escapes a black hole.

I wish we had more than 300 characters to talk about these things.

@GShock112 Because quantum mechanics demands that matter CAN escape. It's not very likely for an individual particle to escape, but if given enough time, it does happen.

@jaimesthesaint

Nothing escapes from INSIDE the event horizon hence the radiation can't come from inside. It must come from outside, in the proximity of the EH but there's NO WAY it can can strip something from inside the EH bc the singularity inside has an unparalled strenght of attraction.

How can a BH evaporate if it keeps eating matter and nothing can escape... it doesn't make any sense. I really can't understand.

[jaimesthesaint]

@GShock112 Through the same process that allows the sun to fuse hydrogen, even though its core is too cold: quantum tunneling.

When you apply quantum mechanics to black holes, you find that a horizon can't be a perfectly smooth surface - it has to fluctuate, and some of these fluctuations may be big enough to pinch off a tiny piece of the black hole.

When the temperature of space drops below that of black holes, the tiny amount of radiation they emit will start to be more than they absorb.

@jaimesthesaint

Jesus Christ maybe I can't explain myself. How can the BH EMIT and RELEASE or as you say "give off" if NOTHING, NOTHING escapes a black hole?!

The Gas jets at the poles of a rotating BH do not come from the BH but from its vicinity because of magnetic fields that the rotation (the TWISTING actually) of space time has around the BH but NOTHING escapes the BH that's why I don't understand this radiation. How can something that lets nothing escape EMIT something??!!?!?!?!?

@GShock112 If you want more detail, I recommend reading The Black Hole War.
