Stephen Hawking once came up with an argument that black holes aren't completely black, but they emit small amounts of radiation. Since the energy that produces the black hole comes from its mass, the black hole gradually shrink. In fact, the smaller the black hole, the faster it shrinks due to this radiation.

What causes a black hole to become smaller?
As the mass of the black hole grows greater and greater (from sucking in everything around it) it has an ever increasing gravitational force that pulls its outer-lying matter inward more and more and thus increases its density by decreasing its volume
What is an intermediate black hole?
An intermediate-mass black hole is one that has a mass somewhere between 100 and a million solar masses, i.e., larger than the stellar black holes, but smaller than the supermassive black holes. It seems likely that such holes should exist, but the observational evidence is not yet very firm.An intermediate black hole is one whose mass is somewhere between that of a stellar black hole (a few times the mass of the Sun), and that of a supermassive, or galactic, black hole (millions or billions of times the mass of the Sun).
Why does a black hole have more gravity then the star it once was despite having the same or less matter?
This is a common cause of confusion. In a way, if no mass got lost in the creation of a black hole, then it will have exactly the same gravity than before. For example, if our Sun converted to a black hole (not that it is planning to do so...), our Earth would continue orbiting this black hole, in the same orbit as before. What makes a black hole different is that the mass is very concentrated; so, it is possible to get much closer to the black hole - and remember that gravity gets stronger at shorter distances.
Can a person be pulled by a black hole the size of a quarter?
The answer to this question depends on what is meant by 'size of a quarter'.Black holes themselves are mathematically considered to be points; therefore, every black hole in existence is not only smaller than a quarter, they're smaller than even the nucleus of an atom.If the black hole has an event horizon that reaches approximately one inch (2.5 cm.) out from its center, then the answer is very likely yes. Such a tiny black hole would still have approximately the mass of a planet, and we all know from direct experience how powerful Earth's gravity is.But if the black hole has the mass of a quarter, then the answer is obviously no.
Where will you go if you fall in to a black hole?
Into the black hole's singularity.
Is a black hole small?
Yes. It's physically impossible for anything to be smaller than a black hole.
Is the Milky Way much smaller than the black hole?
No - The volume of the Milky Way galaxy is larger than the volume of its host black hole. The accumulated mass of the Milky Way galaxy is greater than the mass of its host black hole. The density of the Milky Way galaxy is much smaller than the density of its host black hole.
Which is smaller a black hole or the milky way galaxy?
Most identified black holes are much smaller than the Milky Way. If there was a black hole the mass of the Milky Way (which is probably 100,000 light years across) it would only be about 2/5ths of a single light year in width. Even the largest known black hole is much smaller than our galaxy.
What can destorya black hole?
In general, nothing. Another black hole could swallow a smaller one, if it's small enough it would destroy itself, but anything else would lose to the black hole.
What is the size of a black hole and how does it affect its gravitational pull?
The size of a black hole is determined by its mass, with smaller black holes having a smaller size. The gravitational pull of a black hole is incredibly strong due to its mass being concentrated in a very small space, creating a powerful gravitational force that can even trap light.
Can you destroy the black hole?
Yes the black hole can be destroyed. However, man-made objects cannot resist the gravity without getting sucked in. The only thing that can destroy a black hole is time in a process called Hawking Radiation in which the black hole evaporates over time. The smaller the black hole, the faster the process.
What is bigger a quasar or a supermassive black hole?
The quasar is bigger. A quasar is a disk of superheated matter that surrounds a supermassive black hole. The mass of the black hole may be greater than that of the disk, but it is compacted into a smaller space.
When they in the hole were they go?
If you are talking about a black hole, then you get squished into a ball smaller than an atom and keep going, or time can change.
Is a black hole bigger than galaxy?
No. At least, the black holes in existence so far are much smaller in size, and have much less mass, than a galaxy. However, note that the black hole in the center of the largest galaxies can have more mass (but not more diameter) than some dwarf galaxies.
How small would the Earth appear if it were inside a black hole?
If the Earth were inside a black hole, it would appear much smaller due to the extreme gravitational forces bending light.
How long will a black hole live?
That depends a lot on the mass of the black hole. The smaller black holes will evaporate more quickly. A stellar black hole (a few times the mass of the Sun) is expected to live approximately 1066 years, while a supermassive black hole might survive something like 10100 years before evaporating completely.
How does a black hole disappear?
As Stephen Hawking demonstrated mathematically, black holes can evaporate by emitting what is now known as Hawking radiation. The smaller the black hole, the faster the rate of evaporation. And they can evaporate until they are completely gone.
