Is it theoretically possible to use a black hole as an energy source, & would it deplete the black hole?

Question

I saw the film Event Horizon, and I have been asking the question ever since, would the black hole diminish the more power we drew from it, like our use of oil here on earth, or would we be using the forces a black hole creates instead? Answers in English please, if one single number shows up my eyes will cross and my brain shut down!

Answer 1

You could theoretically use a black hole to convert mass into its energy equivalent fairly efficiently. For instance, if you lowered a bag of garbage on the end of a cable wound round a drum, located on a platform at a safe distance, the drum would rotate and produce power until just before the garbage bag crossed the black hole's event horizon, when the cable would snap. A rotating black hole has a spherical event horizon, outside of which is a surface of infinite red shift. Between these two surfaces is a region called the ergosphere. You can enter the ergosphere and escape through the surface of infinite red shift with more energy than you had when you entered it. You'd have extracted mass-energy from the black hole. When matter spirals into a black hole, it heats up and emits both electromagnetic and gravitational radiation before it disappears inside the event horizon. In some circumstances it can radiate nearly 50% of its mass before disappearing.

Answer 2

For an energy source we need one input and at least one output... Unfortunately we yet not have found the output region of black holes.. So till then, it is not possible...
But if we found a neutral point near the black holes, the we can use the radiations emitted by the black holes to produce energy... Without finding it's either/output side !!!

Answer 3

I don't understand the question, how can you remove energy from an object that emits nothing?
A black hole, is NOT a hole!
It is a star, like any other star, only its mass is so great its gravity equals the speed of light, so no light can escape from the surface!
The name black hole comes from the description of what it would look like in space.
Everything that passes the event horizon is on a one way journey, and NOTHING can escape, it will be crushed to a quantum factor of 0.

Answer 4

It is possible in theory and not only would it not deplete the black hole but it would probably make it bigger. The idea is to drop mass into it. The mass will radiate high energy photons as it falls in, and of course after it falls in it is there for good, adding to the mass of the black hole. You could run out of mass to throw in I guess, but if you can get to a black hole in the first place you can probably round up as many asteroids or as much interstellar dust as you need.

Answer 5

No. A black hollow is a determination of count. If the black hollow isn't very massive, Hawking radiation will enable it evaporate into our Universe. An Earth-mass black hollow could nonetheless internet eat and stay black. If the black hollow had the mass of Mt. Everest, it may be warmer than the CMBR and could evaporate in some hundreds of hundreds of years. Now in case you superhero could regulate the linked fee of light to infinity in some great area of area, he could doubtlessly divulge the contents... notwithstanding it may type a black hollow back basically approximately right this moment.

Answer 6

For every black hole there is a white hole, one sucks and one blows. Surely it'd be easier to harness the power of a white hole! Anyway, we're a looooooooooooong way from being able to do anything like that.

Answer 7

A black hole has immense power and will not be diminished because you cannot draw power from it. It's power however, may be utilised and we are working on how, as we speak.

Answer 8

Difinitely no. anything that may come near into it will only be sucked up, even light cannot escape. the only energy being release by blackhole is neutrino which is insignificant energy.

Answer 9

Depends who's black hole it is.

Answer 10

it's possible
