Escaping from Black Holes

Mr Smooth

Now I didn't think anything could come out of black holes but clearly I'm wrong:

How can it be a black hole if stuff is coming out? Small words please!

I think it's matter & energy ejected from the accretion disk, and not coming from beyond the event horizon.

The material isn't coming from the black hole's side of the event horizon, but from our side. It's material that hasn't yet fallen into the hole.

Material CAN leave a black hole though! Hawking radiation is a result of quantum theory in which (to put it simply) electrons can disappear from one point around an atom and then appear in another. If the atom is just on the event horizon then the electronsl can be said to escape the black hole. I'm sure someone else can explain it more accurately :-)

I'm sure there's a cosmological theory which states that due to Hawking radiation all black holes are eventually doomed to lose all the material on the inside of the event horizon and thus not be black holes any more.

Mr Smooth - you are making the mistake of assuming science is fact rather than best fit theory.

Think of it as sort of a black hole when you're off the back. Nothing escapes off the back.
You are sucked out of the front group and forever trapped in that ever darkening area,
"OTB".

Black Holes suck.

Releasing of energy from a black gole is related to the fact that energy cannot be created or destroyed. Fundamentally the fact that matter is captured by a black hole means energy must be realised.

Also, black holes do emit matter. Heisenberg's uncertainty principle (simply) sates that matter can spontaneously come into existance, as long as it is balanced by the appropriate anit-matter. (So there is no net gain in matter or energy to the Univere).
If this happens on the even horizon, one part could be swallowed by the black hole, leaving the other free - and hence emitted from the black hole - kind of indicating that the black hole is actually creating stuff.

Everytime I have almost been sucked into a black hole I have just clicked up a gear and stood up. Quadpower should get you out of any sticky situations like this 8)

Yes, but sometimes you get too close to the event horizon(off the back too far) and no quad power in the world will save you.

Astronomers say the two streams of particles they observed are the most powerful pair of jets ever seen from a stellar-mass black hole.

The other being Petacchi

The spinning of Jan Ullrichs mighty quads in such close proximity to one another often caused the tearing of the space time continuum.

Stuff does come out of a black hole - it's just the opposite end

Airwave

There's also chocolate so dark light can't escape it's surface-eat to much&you dissapear,unlike normal chocolate where you just get fatter

A small black hole has been observed blowing a vast bubble of hot gas 1,000 light-years across.
