Pronunciation: [ɪvˈɛnt həɹˈa͡ɪzən] (IPA)

Event horizon is a term often used in astrophysics to describe the boundary surrounding a black hole from which nothing can escape. Synonyms for event horizon include the Schwarzschild radius, gravitational radius, and photon sphere. These terms all describe the point of no return in relation to a black hole's gravitational pull. The event horizon or Schwarzschild radius is the distance from the singularity at the center of a black hole where the escape velocity equals the speed of light. The gravitational radius is another term that describes the same boundary, and the photon sphere is the outermost boundary within which photons can be forced to travel in circular orbits around the black hole.

Famous quotes with Event horizon

  • My to-do list is so long that it doesn't have an end; it has an event horizon.
    Craig Bruce
  • Elvis' disappearing body is like a flashing event horizon at the edge of the black hole that is America today.
    Arthur Kroker
  • Read one page of Stephen Hawking about the event horizon, about the possibility that we will soon know, not where the universe originated, but where it is tended, and the event horizon to which we may all be headed. There is more to inspire awe in one page of Stephen Hawking, than in any of the fantasies of Tertullian, imagining that he could go to the window of heaven, when he was promoted there, and look down, for his consolation, on the torments of the damned. There is much more to be awe-inspired by, in a page of Hawking, than in any number of burning bushes, or other such myths.
    Christopher Hitchens
