Black Hole | Painted Clothes

Black holes are among the most mysterious and awe-inspiring phenomena in the universe, with a gravity so strong not even light can escape. First proposed by John Michell in 1783, the concept of a body so massive that not even light could escape its gravitational pull has fascinated scientists and the public alike. The discovery of the first black hole candidate, Cygnus X-1, in 1971 by a team of scientists including Louise Webster and Paul Murdin marked the beginning of a new era in astrophysics. With the detection of gravitational waves by LIGO in 2015, confirming a key prediction made by Einstein's theory of general relativity, our understanding of black holes has significantly expanded. The supermassive black hole at the center of the Milky Way, Sagittarius A*, has a mass of approximately four million times that of our sun, and its event horizon is about 12 million kilometers in diameter. As our knowledge of black holes continues to grow, so does our appreciation for the profound impact they have on the universe, from shaping galaxy evolution to influencing the formation of stars.
