What does a Black Hole do with all stuff it eats up like matter, light, and time?

Question

What do Blackholes do with everything the eat up? How long can black hole survive untill it dies? What happens to everything that inside of it? Does it go back out into space?

Answer 1

It gets bigger.
Seriously.

The event horizon expands as the mass of the black hole increases. The event horizon is the limit of where nothing gets back out of the hole and is the 'size' of the black hole.

I would read any book by Stephen Hawking (like
'Black Holes and Baby Universes and Other Essays' or 'A Brief History of Time') for a great description of what they are. Also Brian Greene describes black holes in his book The Elegant Universe. There are also lots of papers that will describe it with a lot more math in them than non theoretical physicists should ever have to deal with.

It has been shown that black holes radiate energy and thus lose mass (at the same time as they gain mass from anything that gets within the event horizon) so theoretically, black holes can (if they lose mass at a greater rate than they gain) 'die'. The mass of the black hole is indeed sent back out into space.

Answer 2

It eventually crushes the material out of existence at the singularity. How long do they survive??......depends on the size of the hole. Mini ones the size of protons but as heavy as mountains eventually lose enough mass (via Hawking Radiation) to explode. Large black holes.....stellar mass and larger, take the best part of forever to do the same as the mini holes, so you have no worries. As far as what happens at the singularity, it's most likely that the matter which is crushed out of existence becomes "smeared" as a quantum probabilty function and enters higher dimensional space as a form of quantum energy. It most likely enters a superposed state of existence......both existing and not existing at the same time, as that energy.

Answer 3

As others have pointed out, black holes do eventually "evaporate" by slowly radiating out all the matter & energy that have fallen into them. The smallest stellar black holes will still take a staggeringly long time to decay: at least 10^65 years. By comparison, our universe is a bit over 10^10 years old, and all "normal" matter will have decayed away in about 10^34 years.

For effect, I was going to write out those time periods in long form, but Yahoo actually won't allow me to show numbers with that many digits in them! (It truncates them with a "...")

Answer 4

a black hole is a gravity well.it consumes everything that gets within its grappling range.nobody knows for sure but in theory, a black hole devours everything without it being expelled.the matter that is trapped there becomes denser, making the black hole that much more powerful.in other words, it is squeezed into a tiny area and becomes more energy that intensifies the strenght of the black hole.eventually the black hole becomes so dense that it decays, or collapses in on itself.

Answer 5

due to hawking radiation the black hole will slowly shrink over time (as it release mass in the form of radiation) untill it just disapears. While the black hole exists the matter i crushed into a super dense ball type thing

edit: guy above me beat me to it :-(

Answer 6

Hi,

Some say all the light emerges in some other place in the universe! ... It acts like a tunnel...

Answer 7

Nope. Stays there for eternity. Gravity doesn't have an expiration date.

Answer 8

I think it smashes itself down into a tiny piece, it's own gravity crushes itself....so the more it takes in the more it crushes itself...and the more gravity it creates?
