Introduction Black holes are areas of the universe so dense that even light can’t escape the gravitational pull of them. A usual black holes is round. Black holes are black because light that reflect off the black hole gets sucked in. The edge around a black hole is called the event horizon or the point of no return.There are two main types back holes. One is the Supermassive and another is the stellar. There is another type of black holes still in Research called Intermediate-mass black hole or IMBH.

Stellar black holes Stellar black holes are not very big and range from 3 to 90 solar masses in weight. Stellar black holes are formed by deaths of a large star or gravitational collapse on a large star. Stellar black holes usually are found in the clusters of stars and planets. Stellar black holes are too small to ‘eat’ stars but they are big enough to ‘eat’ planets and other space ‘junk’.

Supermassive Black Holes Super massive black holes are extremely huge and range from hundreds of thousands to billions of solar masses. Supermassive black holes are formed by matter collecting in the center of of galaxies. Supermassive black holes usually appear only in the middle of galaxies but any not in the middle of a galaxy is a primordial black hole.

Wormholes and White holes
White holes are the exact opposite of a black hole. And wormholes are shortcuts through space-time. These two connect to each other because they depend on each other. For instance a white holes would not exist if there is not a external source of matter for it to spit out, so a white hole would need wormholes to transport matter from the black hole to him. Worm holes would not exist if there aren’t white holes because no force is pulling matter trough a worm hole, also if there isn’t a white hole to maintain gravitational balance, the worm hole also gets sucked in the black hole.

Black holes distortion to space time
Every matter makes a distortion to space-time but a black hole’s distortion is extreme. A black hole’s distortion is so gigantic that it makes a hole in space-time. So what ever fell into the black hole would never come out and stay stuck in a totally different dimension or something weirder that mankind has never discovered.
Glossary dimension |diˈmenCHəәn| noun (usu. dimensions) a measurable extent of some kind, such as length, breadth, depth, or height: the final dimensions of the pond were 14 ft. x 8 ft | the drawing must be precise in dimension . distortion |disˈtôrSHəәn| noun 1 the action of distorting or the state of being distorted: the virus causes distortion of the leaves | deliberate distortions of pitch and timbre. • a distorted form or part: a distortion in the eye's shape or structure. dense |dens| adjective 1 closely compacted in substance: dense volcanic rock | swirling, dense smoke. • having the constituent parts crowded closely together: an estuary dense with marine life. solar mass nounAstronomy the mass of the sun used as a unit of mass, equal to 1.989 × 1030 kg. cluster |ˈkləәstəәr| noun • Astronomy a group of stars or galaxies forming a relatively close association. galaxy |ˈgaləәksē| noun ( pl. galaxies ) a system of millions or billions of stars, together with gas and dust, held together by gravitational attraction. • ( the Galaxy )the galaxy of which the solar system is a part; the Milky Way. shortcut |ˈSHôrtˌkəәt| noun an shorter alternative route. gravitation |ˌgraviˈtāSHəәn| noun 1 movement, or a tendency to move, toward a center of attractive force, as in the falling of bodies to the earth. • Physics a force of attraction exerted by each particle of matter in the universe on every other particle: the law of universal gravitation. Compare with gravity. 2 movement toward or attraction to something: a tentative gravitation toward the prices that we saw before the announcement.
