What is a black hole in outer space?

Answer 1

It has been theorised that there may be many super massive black holes in the center of our universe.

Although, i am sure this is wrong because we the universe is forever expanding (this goes in much more detail if you would like to know about it, search dark energy) in different areas, more than others therefore there can be no definite centre to the universe.

How ever all galaxies have a centre and located is 1-2 or more super massive black holes. this only counts if the galaxy is a spiral or elliptical. if the galaxy is irregular than it may just be a star cluster.

Answer 2

A massive star (like twice or more the mass of the Sun). It will exert enough gravity to implode its own mass into its core, while suppressing the outward pressure produced by the fusion reaction taking place in it. This is the essential process that ends up creating a Black Hole.

Answer 3

Partially true.

A black hole is formed when stars of certain types near the end of their lives and end up forming a supernova. When their mass is large enough, the rapid expansion of this mass would cause it to explosively compress into a very dense mass, sometimes forming a neutron star.

If the mass is too great, it will compress even further, eventually forming something called a singularity; A point in space where mass is compressed to such degree that it creates a gravitational field so large that not even light can escape it. This field only has this capabality -of capturing light- to a certain distance from the singularity. This border -the place where light is trapped- is called the even-horizon.

This event-horizon is what gives the singularity the name of a 'black hole': Light cannot escape past this point and thus can not be observed any longer. Instead we see a large black void; a 'black hole'.

The mass of a black hole is so massive that it weighs down on the fabric of space-time to such degree that you can speak of a 'hole', since it's an semi-infinite gravity well.

Answer 4

It was a star that went supernova, and then collapsed into a super dense mass that with gravity so strong light can't escape.

Answer 5

the collapse of stars that are about 4 times bigger than the sun. it collapses so greatly that nothing in the universe can stop it, and it becomes a black hole.

Answer 6

the black hole is a matter in outer space that is made by the force of gravity

Answer 7

In general relativity, a black hole is a region of space in which the gravitational field is so powerful that nothing, including light, can escape its pull.

Answer 8

There are no black holes in our Solar System. The closest known black hole is V 4641 and is approximately 1,600 light years away in the constellation Sagittarius.
