This could take a very long time, more time than the present age of the universe.

When i read this, i was wondering about something.

lets say somewhere the time the next Big Bang is going to happen. But before it does, there are lots of Black holes left behind in the universe, big & small ones.

So when the Bang go boom & a new universe is created. Would the new universe be in danger of the past existing black holes?

or would the resulting explosion get rid of existing black holes?
:rookie:

That and the massive tidal effect as you near the singularity. And then there is the Singularity itself that is at infinite destiny...

Increasing the volume of the blackhole doesnot help, Backholes contantly alter their volume via quantum effect, the Horizon will shift, form apparent and actual horizon. the massive gravititional effect is due to the fact at the center of the blackhole is a singularity of infinite density.

Ony by rotating ( and charging) a blackhole you can alter the shape of the Singularity, forcing it to become ring shape. Rotating the blackhole fast enought will alter the stress on space and time forming 2 horizons, the faster the BH spin the closer they get, when they over lap, the Backhole is singularity can now be reach and no horizon exist to prevent a traveller escape.

gravity is a distortion of spacetime.

think of a bowling ball on a sheet. the bowling ball would tend to pull the sheet down, stretching it out of shape. now apply force to the edges of the sheet to resist the pull of the bowling ball.

if you could expand the space between the molecules of the sheet, the bowling ball would appear to have less pull on it, although both their relative masses would remain the same. you could therefore reduce your escape velocity as the sheet returns back to its "normal" flat shape.

either method is plausible, but entirely too impractical, given the amount of energy needed to perform them.

i would simply steer around it.....

Expanding space requires basically anti gravity, or negative energy ( this create anti gravity or negative pressure), as it stand this is behind Hawking radiation.

When ever a particle is created and escape the area of a blackhole via hawking radiation it causes the blackhole to shrink.

Your theory in order to work would require amount of negative energy on a massive scale. Instead of expanding a blackhole it cause it to get smaller and smaller, as positive field energy is negated by negative field energy. You must continue this Till the hole shrinks to a size where the massive degenerative pressure generated by the matter hypercompress in the singularity causes the blackhole to explode..No one is sure what left behind at this point.

The only way to increase the volume of a blackhole is via quantum fluctations and there is no way to decrease it density one a singularity is form as the actually size of the blackhole is determine by it point where the escape velocity is equal to light, and no matter is involved just fields that have no density components. All matter of a blackhole is in the singularity or soon to be merge into it..

correct.

...and where would one find a charge substantial enough to force the balck hole to spin faster?

the last time i checked, they were all out of quasars at my local wal*mart....

Hummmm Anyone that can mess with a blackhole can figure a way to provide a charge and to spin it. ;)

either way, you're looking at one hell of an electric bill......

Well This is another way that I just found.

Apparently dark energy, the same stuff responible for the inflation of the universe and it eventual destruction via the big rip will also cause a blackhole to evaporate, just like negative energy.

Apparently this is seen as a reason why the blackhole at the center of Galaxies are not bigger, apparently blackholes also eat dark energy and it causes them to shrink..

Does this in a way, answer my question?

Well it does, since negative energy would be hard to produce, but dark energy make up 95% of the universe. All you have to do is tap in to enought that would equal the mass energy of the black hole, and feed it to the black hole and it would evaporate aways into a stream of subatomic particles.

Has anyone ever stopped to ponder that being that the Universe is over 90% Dark Matter, How many Dark Matter Particles are most likely flowing through our bodies right this moment? :question:  Food for Thought

Actually it dark energy and it I mean to say 75 %.. Dark matter which is different is around 15 to 20 % and normal matter around 5 to 10%

And yes some darkmatter, like Neutrino and Axions would surround us like an invisible sea. It calculated that 100's of neutrino pass thru your body per second..
