Can black holes be destroyed and how?

Answer 1

Black holes are the last stage of star in which the gravitys is dense that it does not allow even light to pass through it and hence it is called black holes.

Black holes swallows the planets and converts it into the energy and lives on it. They don't even leave a sun to escape from it. These black holes are still a mystery. Only known about it is that it is dangerous. No black holes are formed near our Solar System or Galaxy to examine carefully and collect information about it.

Black holes can be destroyed it the same amout of energy is submitted to explosion inside it making its gravity weaker.

Answer 2

Black holes will eventually evaporate into nothing or very small remnants. You may call this as the destruction of a black hole.
There is no other way in which a black hole can be destroyed. For a discussion of black hole radiation, called the hwking radiation please see the notes below:

Black Hole Radiation:
Classically, black holes are black. Quantum mechanically, black holes radiate. Recent attempts to understand black holes on a quantum level have indicated that they radiate thermally (they have a finite temperature, though one incredibly low if the black hole is of reasonable size) that is proportional to the gradient of the gravity field.

This radiation known as Hawking radiation, after the British physicist Stephen Hawking who first proposed it. Hawking radiation has a blackbody (Planck) spectrum with a temperature T given by
kT = hbar g / (2 pi c) = hbar c / (4 pi rs)
where k is Boltzmann's constant, hbar = h / (2 pi) is Planck's constant divided by 2 pi, and g = G M / rs2 is the surface gravity at the horizon, the Schwarzschild radius rs, of the black hole of mass M. Numerically, the Hawking temperature is T = 4 × 10-20 g Kelvin if the gravitational acceleration g is measured in Earth gravities (gees).
Hawking Radiation is due to the capture of virtual particles decaying from the vacuum at the horizon. These are created in pairs and one of them is caught in the black hole and the other is radiated externally.

The energy that produces the radiation comes from the mass of the black hole. Consequently, the black hole gradually shrinks. It turns out that the rate of radiation increases as the mass decreases, so the black hole continues to radiate more and more intensely and to shrink more and more rapidly until it presumably vanishes entirely.
Actually, nobody is really sure what happens at the last stages of black hole evaporation: some researchers think that a tiny, stable remnant is left behind. Our current theories simply aren't good enough to let us tell for sure one way or the other. As long as I'm disclaiming, let me add that the entire subject of black hole evaporation is extremely speculative. It involves figuring out how to perform quantum-mechanical (or rather quantum-field-theoretic) calculations in curved spacetime, which is a very difficult task, and which gives results that are essentially impossible to test with experiments. Physicists *think* that we have the correct theories to make predictions about black hole evaporation, but without experimental tests it's impossible to be sure.


Cheers.

RE:
Can black holes be destroyed and how?

Answer 4

Perhaps one way of doing so, would be the collision of multiple black holes. The gravity would be powerful enough to "overload" the black holes. But the aftermath would probably be apocalyptic to any nearby.
Though i would say it is quite impossible for even two black holes to get near each other. Unless the universe contracts suddenly, it might happen. Which coincidentally, it would when the universe starts to move toward the Big Crunch.

Answer 5

Eh. Black holes are still a mystery to many scientists. Yes they could be destroyed, but not by the human system or technology. Just let the universe take care of it, we will never know "how"

Answer 7

probably they can but at this point of time they are capable of destroying anything we know of and till we come up with something more powerful than the black hole they will remain indestructible

Answer 8

The only theory I have heard about black hole destruction involves Hawking radiation. It is way beyond my understanding as to how the math in this theory works out.

Answer 9

eventually black holes will destroy themselves. when the universe outside of hem is cooler than they are (yes -270 degrees celsius is still too warm) they will radiate their energy away slowly through hawking radiation, and when they get small enough they will explode.

piling more than one black hole together will simply make a bigger black hole, it won't "overload" them. only hawking radiation would get rid of them, anything else would just feed them.

Answer 10

Absolute zero temperature applied sub-dimensionally would make it sniffle, altho you'd have ta freeze the whole thing to keep it from inverting the - 270 degrees to plus super quasar temperature. the - 270 is theoretically correct, the Hawkin radiation wut be sub,very sub dimensional and might implode inward on itself as it needs heavy mass to create it's frequency which is most likely very dense, and I wouldn't want to be around when relatively heavy frequencies implode, it would probably rip out the area of two or three galaxies
