How do you destroy a black hole

How would you destroy a black hole?

Welcome to How to destroy a black hole for dummies

Are you looking for a way to get rid of the right black hole, right? Well, you are reading the correct guide. But before you begin, it might be useful to make some clarifications about the nature of these galactic monsters. As Sun Tzu says, in order to defeat your enemy, you must know him first. Let us know what a black hole is.

1) Why are black holes such a formidable enemy?

Black holes are the natural enemies of all space routes. With their bottomless ability to consume all light and matter, it takes only a few septillion years for all things in the universe to find their way into the cavernous throat of a black hole that is crushed into the infinitely dense singularity. In the case of a black hole, any matter that enters the event horizon is added to the mass. Shoot bullets at a black hole and you're just making a slightly more massive, slightly more dangerous black hole. Detonate an atomic bomb within the event horizon and you will only make the black hole more massive. Fire your forward phasers at the black hole and that will make it even more massive. Swap these spheres for lasers and black holes. Within the event horizon, energy and matter are one, and it is precisely these black holes that can convert this energy into mass. All of your projectiles and energy weapons inevitably make it more dangerous. So the problem is that any material that is introduced into a black hole (whatever physical matter or energy is) is swallowed and contributes to the enemy's growth.

What if i use an anti-matter weapon?Maybe throw an antimatter black hole in a black hole?We have a nice KABOOM and the problem is solved

Nice try Jimmy. The problem is that even if you manage to create and stabilize an anti-matter black hole (and this is doubly impossible because you have to first find a way to contain antimatter and then find a way to contain antimatter if you throw it at a black hole it will surely cause a huge explosion, but all the energy will be converted and processed by the black hole. The bottom line is that if a normal black hole and an antimatter black hole in space married a black hole, they wouldn't go away.

2) solutions

So what are the possible solutions to destroy a black hole? The answer, surprisingly, lies in the characteristics of the enemy. We have to take advantage of the enemy's ability and turn it against it.

Waiting

Yeah ... just wait. I know it's the most boring thing, but at least it's a solution. According to Stephen Hawking, black holes can actually evaporate over enormous periods of time. For an incomprehensible period of time, even the most supermassive of the black holes will have evaporated into harmless particle soup. It turns out that we just have to ignore them to defeat the black hole threat and they will go away on their own. But if you asked how to destroy a black hole, now I guess you need it. So the next solution is ...

Get rid of the event horizon

When you get rid of the events, you get two interesting results. First of all, you get what you want: you killed a black hole. Plus, once you've cleared the horizon, you'll have access to the real black hole and all of its secrets. The problem is that this solution is a little complicated.

In general relativity, the mathematical condition for the existence of a black hole with an event horizon is simple. It is given by the following inequality:

M.2> (J.M.) 2 + Q.2
where M. is the mass of the black hole, J. is its angular momentum, and Q. is its charge.

Removing the event horizon is simply a matter of increasing the angular momentum and / or charge of that object until the inequality is reversed. In this case, the event horizon disappears and the exotic object below appears. But that hides a multitude of problems. First of all, things with angular momentum and charge also tend to have mass. In either case, the above equation describes a steady state. Feeding a black hole creates a dynamic state and there is no guarantee that the object will revert to a stable state again without losing the angular momentum and charge it supplied. In fact, the calculations are so diabolical that they have defied all attempts to tame them.

Use time travel device

Do you remember when we said that black holes dissolve in time? Sure, it takes eons, but what if you could speed up time? Creates a kind of space-time bubble and speeds up time. The black hole will disintegrate as expected, or even faster if not fed.

You cannot remove the event horizon in the specified way. There is a maximum angular momentum a bra can have. I can't explain why charging isn't working the way naive analysis suggests, but that's a good question for physics.

"Maybe Faster" The Hawking Radiation character isn't counting new infalling material, so that's the fastest rate out there.

Yaniv

@ JDługosz But the limit is physical or can it be reached by a Unobtanium device?

The Vee

@ JDługosz The physical argument for charging is that if you want to add more charge to your black hole, you have to overcome the repulsive force between similar charges. Otherwise, the charges would simply be dismissed and dismissed. With extreme charges near the extreme black hole, this requires so much energy that if you manage to push the charge all the way in, a significant amount of mass (E / c²) will inevitably be added as well, which always enough to keep the inequality on the same side. This and a similar finding for J essentially form the principle of cosmic censorship.

Trichoplax

If you put a large enough amount of antimatter in one place, you won't get a black hole for antimatter. You only get a black hole. Only charge, mass and angular momentum can be measured. Not a big explosion if you put it in another black hole made out of matter. Well, no difference to the introduction of two other black holes. It is a violent event, but not because of the antimatter.
