   John Michelland Pierre-Simon Laplace 1783 & 1796 first mentioned about the classical bodies which have escape velocities greater than the speed of light with a huge gravitation, from which even light cannot escape.  William Clifford 1876 suggests that motion of matter may be due to changes in the geometry of space.  Albert Einstein 1915developed the theory of general relativity.

   Jacob Bekenstein1972 suggests that black holes have an entropy proportional to their surface area.   Stephen Hawking 1972 proves that the area of a black hole's event horizon cannot decrease.  Max Planck Institute 2002 evidence for the hypothesis that Sagittarius A* is a supermassive black hole at the center of the Milky Way galaxy.  NASA's 2002 Chandra X-ray Observatory identifies double galactic black holes system in merging galaxies NGC 6240.  UCLA 2004 present even stronger evidence supporting Sagittarius A* as a black hole.

   Karl Schwarzschild1916 give how to find the radius of black hole.  Subrahmanyan Chandrasekhar 1931 calculates a special limits (1.3 solar mass )of which black hole and other massive star formed.  Robert Oppenheimer 1939 predict that massive stars can collapse into black holes.   John Wheeler 1967helps to popularize the term "black hole"

   Johns HopkinsUniversity 2012 First visual proof using the Hawaiian telescope Pan-STARRS 1, publish images of a supermassive black hole 2.7 million light- years away swallowing a red giant.  LIGO On February 11, 2016, published a paper about the detection of gravitational waves, from a signal detected at 09.51 UTC on 14 December 2015 of two ~30 solar mass black holes merging about 1.3 billion light-years from Earth. first observation of gravitational waves; because these waves were generated from a black hole merger it was the first ever direct detection of a black hole., a second detection on June 2016.

   The regionof space where nothing, not even light can escape is called Black Hole.  The massive body who’s escape velocity is equal to the speed of light such masses is called Black Hole.

  It would beconsidered that when a red joint completed their age then it collapses itself and turn out in black hole.

   Density If wecompress the earth by such a way that it become equal to a golf ball, it would be consider that infinity.  Gravity Gravity pull is so strong that nothing can escape even light can not escape out from a Black Hole.

   If youfall inside the black hole then you squeezed and stretch out just like noodles(spagtti), and it turn into invisible particles this region is called Singularity.

  A region wherethe space-time curvature becomes infinite. The center of the Black Hole is most often referred to as the “singularity”. Surrounding the “singularity” is the “evenhorizon”, which is the area in which things are pulled back into the Black Hole.

  SURAH At-Tariq refersto a ‘piercing star’: “(I swear) by Heaven and the Tariq! And what will convey to you what the Tariq is? The Star Piercing (the darkness)!” (Qur’an, 86:1-3) As a muslim, I believe that black hole really exist. Now many space agencies like NASA found them by Space ships.
