Black hole (image: Sabphoto).

A black hole is an area in space where the force of gravity is so strong that light cannot escape. The pull of gravity is great because matter has been concentrated in a small space. This can happen when a star runs out of fuel and collapses into a smaller and smaller space. This lack of light results in the black color.

Stellar Black Hole

A stellar black hole is created when a large star collapses. This occurs when a star is running out of fuel and dying. The star’s outer layers begin to collapse inwards and the star begins to get smaller and smaller. However, as the star gets smaller, its gravitational pull gets stronger and stronger.

Smaller stars will collapse into a neutron or a white dwarf star. But if the star is large (more than three times the mass of our sun), it collapses into a stellar black hole.

Supermassive Black Hole

The supermassive black hole is found at the center of galaxies. Its mass could be equal to a million of our suns. It is thought that these were created when a galaxy was being formed.

The collapse of many smaller black holes, of massive clouds of gas, or of many stars could create the supermassive black hole.

Miniature Black Holes

Tiny black holes may have been formed when the universe was created. Following the Big Bang, miniature black holes may have been created. These have a mass that is much less than our sun compressed into the size of an atom.

Ang mga itim na butas ay pinaka masakit at hindi mo alam na asan kana kapag papasuk ka diyan.At hindi mo alam na mamatay ka ba o puhay ka sa ibabg mundo .Kaya ito parin ay makaingat ka dapat at hindi ka mag punta diyan kapag meron kang makita ninyan.

When the sun or other star’s go supernova they will be shiny bright but some of then became red and it burst.And when it but some of its body explode but one body will suck the explosion and until it became a little bigger.And until it becomes bigger it will go sucking other gas like a typhoon. And when it suck you, you don’t know where you are or what universe are you in.Some people said that a black hole when you are sucked and suddenly you will be like a sand or killed.

Ang mga tao sinabi na ang black hole ay mapanganib. Ito baguhin ang mga tao ng isang ang astronot upang hindi pumunta. sa bi ng iba na ito ay hindi cana makakalabas dito.

There are three types of black hole.
1.Supermassive Black Hole
2.Stellar Black Hole
3.Miniature Black Holes

A supermassive black hole is found in the center of the galaxy.
Stellar Black Hole occurs only when a star is out of fuel and it starts dying.
Miniature Black Hole its mass is much less than our sun compressed into the size of an atom.
Atoms as a source of nuclear energy.
