  • Edward Lorenz, chaos theory

  • Roger Penrose, black holes must contain singularities

  • Roger Penrose proves that an imploding star will necessarily produce a singularity once it has formed an event horizon

  • Stephen Hawking, the surface area of a black holes event horizon always increases

  • Stephen Hawking proves that the area of a classical black hole's event horizon cannot decrease

  • Hubble Space Telescope, Evidence for black hole at the centre of galaxy M87

  • NASA's Chandra X-ray Observatory identifies double galactic black holes system in merging galaxies NGC 6240

  • Further observations by a team from UCLA present even stronger evidence supporting Sagittarius A* as a black hole.
