Quote:interesting question,
Blackholes are spheres with very very high gravitational force. Even light can not escape that force. So even if the bomb explodes, we won't be able to observe it. Blackholes are made from high density neutron star. You can’t expect a blackhole to be destroyed just by an explosion of neuclear weapon.
Bomb explosion would release a huge amount of energy (assuming it reaches the “surface” of blackhole and explodes). Blackhole treats energy and mass equally. So it will absorb all the energy released by the bomb.
Lets assume we throw the bomb at event horizon. Time is slow there, much much slower then in our normal world. So before the bomb reaches the center, we might have passed 100s or 1000s of earth years. So if you are the person to drop the bomb, you probably wouldn't be the person to observe it when it explodes. Fascinating, isn't it ?
A black hole is how you make atomic bombs get lost for 100s or 1000s of earth years near the hole's event horizon.
Don't believe the misleading posts trying to cover this fact.
Just a few pesky facts to ruin your day:
- What the researchers made in the article you cited was not a black hole. It was a black hole analog. That's something that has certain properties that we might expect a black hole to have without being an actual black hole. What was actually produced was a Bose-Einstein condensate made of 8000 super-cooled rubidium atoms. It was so fragile that they destroyed it every time they took a picture of it. Needless to say, this won't be stopping any nukes any time soon.
- Black holes are not your friend. They are top contenders for the most destructive phenomena ever discovered. The small ones "evaporate" with a detonation that outstrips any bomb that humans have ever conceived of. The mid-sized ones simply swallow the entire planet. The really big ones devour the solar system in one gulp. Do I need to explain why this would be a bad idea?
- Throwing a nuke into a black hole, or a black hole at a nuke, is one of the more absurd ways of actually making a nuclear bomb worse. Nuclear weapons are relatively inefficient at converting mass to energy, managing only a percent or two at the best of times. By contrast, a black hole can liberate more than 50% of the energy equivalent of any infalling mass. This is how astronomers can study black holes in other galaxies by looking at the gamma radiation that they emit. So your "solution" makes an explosion an order of magnitude larger than the nuke itself would have. And that's just the nuke. Once your black hole started pulling in atmosphere, ocean, and bedrock you'd have real trouble. It would effectively turn any nearby mass into a nuclear explosion.
TL;DR We can't do this and that's a very good thing.
