Some Mysterious Facts about Black Hole 

Do you ever realize that if you collapse into a black hole, you will be able to see the entire future of the Universe which would be unfolded in front of you in a matter of moments and you will appear into another space-time created by the singularity of the black hole?

What is Black Hole?

A Black Hole is a region of space-time from which gravity averts anything, including light, from escaping. The theory of general relativity anticipates that a sufficiently compact mass will distort spacetime to form a Black Hole. Around a black hole, there is a mathematically identified surface called an event horizon that marks the point of no return.

Reason behind the Hole is black

 The hole is called "black" because it soak ups all the light that hits the horizon, reflecting nothing, just like a perfect black body in thermodynamics.

History of Black Hole

The idea of a body so huge that even light could not escape was first put forward by John Michell in a letter which was written to Henry Cavendish in 1783 of the Royal Society

If the semi-diameter of a sphere of the same density as the Sun were to surpass that of the Sun in the proportion of 500 to 1, a body falling from an infinite height towards it would have obtained at its surface greater velocity than that of light, and as a result supposing light to be attracted by the same force in proportion to its vis inertiae, with other bodies, all light produced from such a body would be made to return towards it by its own proper gravity.

A black hole is a place in space where gravity drags so much that even light cannot get out. The gravity is so strong because substance has been squeezed into a small space. This can happen when a star is dying.

How gigantic is Black Hole

Hole  might be small or big. The scientist view on this aspect on that the smallest Hole are as small as ATOM. These black hole seems very petite but have the mass of a large mountain. The other kind of black hole is called “stellar”.   Its mass can be up to 20 times more than the mass of the sun in its specialties term.  There may be many, many stellar mass black holes in Earth's galaxy. Earth's galaxy is called the Milky Way.

The Largest Black Hole 

The largest black holes in the space  are called "supermassive." These black holes have accumulations that are more than 1 million suns together. Scientists have found proof that every large galaxy includes a supermassive black hole at its center. The supermassive black hole at the center of the Milky Way galaxy is called Sagittarius.

Origins of Black Hole 

It has been scientified that  the smallest black holes formed when the universe began. Stellar black holes are prepared when the center of a very big star cataracts in upon itself, or collapses. When this occurs, it causes a supernova. A supernova is an exploding star when they get blast in space. 

If Black Hole is Black than How Scientist can see it..!!!

A black hole cannot be assumed and seen because strong gravity pulls all of the light into the middle of the black hole. But scientists can see how the strong gravity affects the stars and gas around the black hole. Scientists can study stars to find out if they are flying around, or orbiting, a black hole. When a black hole and a star are close together, high-energy light is made. This kind of light can not be seen with human eyes. Scientists use satellites and telescopes in space to see the high-energy light.

Consequences on Earth by Black Hole 

Black holes do not roam around in space eating stars, moons and planets. Earth will not collapse into a black hole because no black hole is close enough to the solar system for Earth so that it cannot put any negative effect on the Earth. Even if a black hole the same mass as the sun were to contain the place of the sun, Earth still would not fall in. The black hole has the same gravity as the sun has. Earth and the other planets would scope the black hole as they orbit the sun now.

The sun will never revolve into a black hole. The sun is not a that much big enough star to make a black hole.

NASA’s equipments in study of Black Hole 

NASA use satellites and telescopes to study about the black hole. The satellites and telescope move in space to learn more about black holes. These spacecraft help out scientists answer questions about the universe.

7 key facts about Black Hole

• Black holes emit x-ray radiation and get smaller and smaller until they disappear, or "evaporate"..
• The gravity around the "hole" of a black hole is so strong that NOTHING can make its way back out after a critical distance.
• The critical space where nothing can escape is called the Event Horizon.
• Light is not able to travel back out of a black hole after crossing the Event Horizon.
• Any object would be, after being barraged with radiation, distorted, and crushed at the atomic level or lower and therefore would not survive at there. 
• The Singularity is the actual point of destruction, the actual hole part of the black hole, although any object, especially a person, would not be able to  reached the Singularity
• Some black holes are spinning and have many event horizons called the "Ergo sphere", "Outer Event Horizon", and "Inner Event Horizon".
