The mysterious Black hole is a place in space where gravity pulls so much that even light can not get out. The gravity is so strong because matter has been squeezed into a tiny space. This can happen when a star is dying. The boundary from where no escape is possible is called event horizon. The black holes can be either small or big in the space and are visible by space telescopes with special tools. Thy are advanced telescopes with advance technology by which scientists see black holes. The temperature near the black holes are near the billion Kelvins making it approximately impossible to see. The gravitational field were first observed in 18th century by John Michell and Pierre Smon Laplace.
Scientists believe that a black hole could be as small as an atom and their mass is large as a mountain. There is no specific size for an black hole. One kind of black hole is “Stellar”. It’s mass can be 20 times more mass than mass of sun. Almost their mass is more than 1 million suns together. Milky way galaxy also known as Earth’s galaxy has a center known as Sagittarius. It has a mass equal to about 4 million suns and would fit inside a very large ball that could hold a few million Earths. According to researchers and scientists, the life begun from black holes.Stellar black holes are made when the center of a very big star falls in upon itself, or collapses. When this happens, it causes a supernova. A supernova is an exploding star that blasts part of the star into space.Scientists think supermassive black holes were made at the same time as the galaxy they are in.
These black holes are often referred to as Schwarzchild black holes after Karl Schwarzschild who discovered this solution in 1916. According to Birkhoff’s therorem,it is the only vacuum solution that is spherically symmetric.This means there is no observable difference at a distance between the gravitational field of such a black hole and that of any other spherical object of the same mass. In the black horizon, the notion of slurping everything near the black hole is correct near the external gravitational field is identical to that of any other body of the same mass.
Black holes do not go around in space eating stars, moons and planets. Earth will not fall into a black hole because no black hole is close enough to the solar system for Earth to do that.Even if a black hole the same mass as the sun were to take the place of the sun, Earth still would not fall in. The black hole would have the same gravity as the sun. Earth and the other planets would orbit the black hole as they orbit the sun now.The sun will never turn into a black hole. The sun is not a big enough star to make a black hole.
“We’re starting to gather real statistics on binary black hole systems,” said LIGO scientist Keita Kawabe of Caltech, who is based at the LIGO Hanford Observatory. “That’s interesting because some models of black hole binary formation are somewhat favored over the others even now, and in the future, we can further narrow this down.” The black holes are the one of the most mysterious things of the world. Scientist over time reveals new things about the hole. Black holes always remain terrific fodder for science fiction books and movies.
