Best Answer

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 comes after black holes?

After the black hole dies out, (see When do black holes die and/or How does a black hole get smaller) it will become just a vacuum.


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.


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).


What does a black hole do with what it suck in?

The material sucked in to a black hole becomes part of the black hole - that is, a black hole crushes matter to an nearly no size, at all.


What is a black holes life cycle?

A black hole starts as a dying star. As the star gets smaller as it dies, the inner pressure becomes so powerful that the star implodes. When this happens, the smashed atoms of the dead star come together to form a neutron star. When this is crushed to nothing, a black hole is formed. If a black hole does not get enough energy, it will decrease in size and eventually explode.

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.


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 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.


Is there a black hole in this galaxy?

Currently, most astronomers believe there is probably a large black hole at the center of most, if not all, galaxies, including ours. There are also probably many smaller black holes scattered throughout.
