Albert Einstein, who had developed his theory of general relativity in 1915, initially denied the possibility of black holes, [4] even though they were a genuine implication of the Schwarzschild metric, obtained by Karl Schwarzschild in 1916, the first known non-trivial exact solution to Einstein's field equations. [1]
Einstein himself considered the introduction of the cosmological constant in his 1917 paper founding cosmology as a "blunder". [3] The theory of general relativity predicted an expanding or contracting universe, but Einstein wanted a static universe which is an unchanging three-dimensional sphere, like the surface of a three-dimensional ball in four dimensions.
A few months after Einstein rejected the existence of Black holes, Oppenheimer and his student Hartland Snyder published a paper that revealed, for the first time, using Einstein's general theory of relativity, how Black holes would form. [13] Though Oppenheimer and Einstein later met, there's no record of them having discussed Black holes. [13]

The astronomers' discovery proves Einstein's predictions right over a century later. Scientists have seen light from behind a black hole for the first time ever. The astronomers' discovery proves ...
Astronomers say they have for the first time observed an area of a black hole predicted by Albert Einstein about 10,000 light-years from Earth. Study proves black holes have a ‘plunging region ...
Video simulation of the merger GW150914, showing spacetime distortion from gravity as the black holes orbit and merge. The theory of relativity usually encompasses two interrelated physics theories by Albert Einstein: special relativity and general relativity, proposed and published in 1905 and 1915, respectively. [1]
Slow motion computer simulation of the black hole binary system GW150914 as seen by a nearby observer, during 0.33 s of its final inspiral, merge, and ringdown.The star field behind the black holes is being heavily distorted and appears to rotate and move, due to extreme gravitational lensing, as spacetime itself is distorted and dragged around by the rotating black holes.
