Heres a hint, if you have the power to stop a black hole you most likely have the power to relocate to another planet.
Wouldn't the kinetic energy from the bomb just be "absorbed" by the black hole which would just increase it's size and gravitational effects? Not to mention the actual bomb itself which would be ripped apart molecule by molecule as it entered into it's gravitational field. Plus, even if you could "insulate" the bomb against massive g forces, time dilation would mean you'd have to wait for years, if not decades or centuries (or maybe even into the millennia) for the bomb to reach a location where it would have a profound impact on the black hole.
So yeah, either get a new story idea or make one about the inevitability of death as time slows down on Earth so that people have a huge amount of time to live knowing that eventually even with the time dilation, they will be pulled apart by the black hole.
Or you could just pull the space magic card...

Um, isn't Hawking Radiation an incredibly long term process? As in it would take millions of years for a small black hole to expel a fraction of it's total mass in radiation? So it's not a viable solution if that's case.FolkLikePanda said:
I'm going back to the "throwing stuff at it" solution. The trajectory of an object is the sum of the trajectories of all the matter inside it, so adding matter to the black hole that's going in a different direction will cause the black hole itself to go in a different direction. Basically, shoot stuff at it from the side and it'll gradually shift course. Of course, you'd need a planet's worth of matter at least, but as far as I know it's the only way to "solve" a black hole without breaking physics.
1) Open a wormhole to an alternate universe that is exactly the same as ours except from the fact that anti-matter won over matter in that universe inside the black hole.
2) The wormhole will suck in both the anti-matter black hole, and the matter black hole, into the space between the universes.
3) Black holes will cancel each other out and create a massive awesome explosion (Because when antimatter touches matter it reacts violently and there is an awful lot of matter/anti matter inside the two black holes so the magical space portal is necessary so that the black holes don't end up blowing up the galaxy.)
4) Optional: find some way to harness the energy released by the massive awesome explosion mentioned above (Which will be a massive amount of energy because all of the mass inside the two black holes is completely destroyed, and releases tons of energy).
5) ???
6) Profit!

Get the hell out of the way.
There's no way you'll be in possession of anything heavy enough to divert its path and likewise no way to "blow it up".
Waiting it out would take too long (according to the Big Rip theory the universe will die before the black hole does).
So either kiss your arse goodbye or run for the hills (Gliese 581g looks nice).

How delightfully fitting for your avatar.Spitfire said:
But seriously, if you want to keep in with your story, forget Hawking radiation. Takes to much time, impossible in the amount of mass required (as for the quickest way to get rid of it, allow the solar system to be swallowed in, and that would speed up the process by maybe a few million years).
My suggestion would be some mashup of m-theory, supergravity and quantum mechanics, like some clever way to generate gravitons/gravitinos from other dimensions to pull it away or force the black hole to emit them faster (see: http://imagine.gsfc.nasa.gov/docs/ask_astro/answers/980601a.html).
Of course that's still plenty silly hollywood science but not the brutal raping of it that the bomb idea of yours. Seriously, that's just downright retarded.
Black holes are not really infinitely powerful, they follow the same laws of physics just like anything else... at least on the outside. There are cases observed within universe, of two black holes orbiting each other, where the stronger one sucks up the mass of the smaller/weaker one, until it devours it whole. Also, it's theoretically easy to CREATE an artificial black hole, so what I'd to is create one on the way of the rouge BH, that would:Secret world leader (shhh) said:
a) be large enough to just devour it
b) or at least large enough (and in the right spot) to alter its trajectory in a safe way (it really works just the same as with planets, or man-made spacecraft (look up the trajectory of Voyager probes), just on a several (hundred?) orders of magnitude bigger scale)
b) or create it in such a spot and so big, that it would catch the rogue BH into a fixed orbit around itself, possibly also slowly (in the timespan of centuries) devouring it.
c) OR, if you watch this - http://www.youtube.com/watch?v=kw3gzlwhMNc
it is already (almost?) proven to be possible to create a "portal" to a parallel universe, we just don't have energy source powerful enough to be able to do it, but if we did, you could just make one in the right time and right place for the rouge black hole to pass through it, which would basically make it disappear from our universe for good.
for the dramatic purposes, the last option seems most viable, because all the first three options are relatively easy (as it's relatively easy to create a black hole, and it might be practically possible (on a scale big enough for the purpose you need) within 10-40 years, but the parallel universe portal, as you can see in the video, is a pretty much humongous-scale project, which could be done in a "this is the biggest thing the humanity has tried to do in all it's history so far" mood, could take up several years or even decades in the story, if the story requires it (as in "we know this BH is gonna hit us in 20 years, and we have a project that will take about 20 years to complete, if everytihng goes exactly according to the plan), adding all the required drama and tension, and uncertainity whether we'll finish it on time, and whether it will work, and all that good stuff that scifi apocalyptic stories should contain).
You must seek the assistance of The One Above All, essentially god from the Marvel Multiverse. He'll be able to stop it!
I thought the same...Elect G-Max said:
OT: Besides, before the explosive could get close enough, the black hole would've already stretched it and probably dismantled it, making it ineffective. Speaking of which, black holes get to a certain point, to where they shoot out. Why not fill it up fast enough with space-junk and THEN we'd be rid of it.
Speaking of which, black holes aren't even near us... At least not for another good few thousand light years.
This in all likelyhood is the most reasonable solution. That or evacuate the system because if you have the magical technology to stop a black hole you are going to have space flight capabilities.Elect G-Max said:
If you want a sort of pseudo-sciencey way of doing it just make a device/substance/whatever to nullify gravitons. The black hole would then simply dissolve. Impossible to do for a number of reasons, but I don't think you're looking for hard science here.
Alternatively you later wright that they have the tech to make blackholes. Simply create another black hole and create a slingshot to move it away from the solar system.
I have the solution: gravitational towing.
You don't need to destroy it necessarily, just make it not hit your solar system. With enough warning you could theoretically change it's path so that it misses the solar system or just misses all objects and slips through harmlessly.
Build a GIGANTIC spaceship and have it move right next to the black hole, but outside of it's event horizon. Black holes are still affected by gravity like everything else so gradually the black hole will be pulled towards the spaceship's gravity. Gradually the spaceship will be able to tow the black hole in whatever direction it wants. This method [a href="http://arxiv.org/ftp/astro-ph/papers/0509/0509595.pdf"]is already an idea being considered for avoiding asteroids[/a]; a black hole would work the same way, just on a much larger (though is some ways smaller) scale.

First, shut down the circulation of the North Atlantic Current to create giant hurricanes over New York and London. If your scientists can outrun the frost long enough, you might still have some left to run things by the time the storms have caused enough neutrinos to mutate. Pile a whole bunch of fuel rods next to a hydrogen bomb in a vessel at the Earth's core, with the mutated neutrinos placed on top, so you can use the augmented power of the bomb to spray the neutrinos out of the plate boundary near Hawaii. While you're preparing to do all that, find some guys with no experience and train them to fly an experimental untested spacecraft over a couple of weeks. Doesn't matter which guys or what occupation they have, as long as they're photogenic. Also make sure there's one (AND ONLY ONE!!! THIS IS IMPORTANT!!) woman on the crew. Get them to land on the surface of the black hole and drill through the event horizon so that, when the beam of mutated neutrinos arrives, it can pass through the event horizon and hit the singularity at the center. It will then explode and launch the experimental spacecraft back home. Note that this will be noisy, so your team of astronauts must be wearing ear protection while they do this.
This. As long as it has interesting characters and a compelling story, it probably won't matter if it is accurate or not. See for example, every work of sci fi ever. Even 2001 didn't really stick to the whole "reality" thing for the whole movie.Zantos said:
You know, black holes aren't really /holes/, per se. They're actually the remains of a star compressed into a tiny, incredibly dense spot, which causes it to have a ridiculously high level of local gravity. What I'm getting at here is the idea of throwing stuff at it to get it to move isn't entirely ridiculous. The /amount/ of stuff you'd have to throw at it would be ridiculous, but the basic concept isn't. I mean, we're talking about throwing something with the mass of an exceptionally large star at the thing, but if the technology level of your setting is up to the task...
(Note that I am not a scientist, this is just my understanding as a layman.)

Simple: You have Michael Bay write your movie. That will fix ALL your problems with science. And continuity. And... you know... being watchable.Secret world leader (shhh) said:
But in all seriousness, based upon what little I know about the physics, there's almost nothing you can do. A black hole could have the mass of an entire solar system or more. If the black hole were less massive, like, maybe the mass of half the sun, you could create a planet-sized space ship with a vastly powerful propulsion system, get it close to the black hole and gravity-tractor it (check Wikipedia) off course from our solar system.
If it's more massive, the only way to destroy it would be to (somehow) come up with a roughly equivalent amount of anti-matter and chuck it into the singularity. Of course, that won't really help you. First of all, if you had anywhere near the equivalent mass of antimatter...
Wait. Halfway through this thought I may have just figured it out. Dumping an equivalent mass of anti-matter into the black hole would release enough energy to destroy the entire galaxy (maybe even more than that), but if you trickled anti-matter into the black hole, at just the right trajectory, the resulting matter-anti-matter reaction might be enough to change the black hole's course.
Of course, by "trickled" I mean "dump a moon-size ball of anti-matter into this thing every five minutes". So yeah, you're probably still fucked.
Or you could just blow conventional science completely out the proverbial airlock and say "we're going to open a wormhole in front of the black hole, and shunt it halfway across the galaxy". I don't even know if that's feasible, but hey, it's movie science.
