Do black holes "die" out?

Question

If they didn't then would the whole universe be sucked in to one?

Answer 1

Black holes die eventually because they radiate. In classical Newtonian physics, black holes are black. But on a quantum mechanics level, they radiate an exceedingly small number of particles, mostly photons.
The death of a black hole can take ten raised to the 61st power times the age of the Universe for a 30 solar-mass black hole. Mini black holes-the mass of a small mountain-can evaporate in less than the age of the Universe.

Answer 2

BLACK HOLES DON'T COLLAPSE A BLACK HOLE BY DEFINITION IS SINGULARITY WHICH ALREADY HAS COLLAPSED

Most of these people are IDIOTS except for Virginia C. Yes black holes eventually "die out" because they emit small amounts of radiation. A background in Quantum mechanics is required to understand the mechanism for this (ITS NOT A LOOPHOLE, its a very plausible phenomenon). Email me if you would like an explanation. Unfortunately the life time for a stellar black hole to completely evaporate away is about 10^60 times the current age of the universe.

If they didn't then would the whole universe be sucked in to one?
The force of Gravity decreases with the square of the distance from a massive object. Only those objects that pass the event horizon are sucked...don't worry our universe is safe! haha

Answer 3

To put it simply:

- Gravity exhibits a force within a field on objects which possess mass.
- If an object with mass is not within this field, then it will not experience a force, in the case of a black hole, it will not be sucked into it.
- Since the size of a black hole's field doesn't extend beyond its field, it can't suck up the entire universe.

Answer 4

There is this idea that Black Holes may eventually "leak" particles out over an extremely long period of time due to an apparent loophole in quantum physics.

--------------
In physics, Hawking radiation (also known as Bekenstein-Hawking radiation) is a thermal radiation thought to be emitted by black holes due to "quantum effects". It is named after British physicist Stephen Hawking who provided the theoretical argument for its existence in 1974, and sometimes also after the Israeli physicist Jacob Bekenstein who predicted that black holes should have thermal properties. Because Hawking radiation allows black holes to lose mass, black holes which lose more matter than they gain through other means are expected to evaporate, and shrink, and ultimately vanish. Smaller 'micro' black holes are currently predicted by theory to be larger net emitters of radiation than larger black holes, and to shrink and evaporate faster.

Hawking's discovery became the first convincing insight into quantum gravity. However, the existence of Hawking radiation remains controversial....

Answer 5

If we attend the theories of huge figures like Sagan and Hawking, the black holes colapse in themselves. Humankind haven't seen this process yet. Some day they will see it, and the theorie will be proved.

Answer 6

they collapse in on them self over time.
