Event Horizon movie

A rescue crew investigates a spaceship that disappeared into a black hole and has now returned...with someone or something new on-board.

In general relativity, event horizon is a general term for a boundary in spacetime, defined with respect to an observer, beyond which events cannot affect the observer. Light emitted from inside the horizon can never reach the observer, and anything that passes through the horizon from the observers side is never seen again. A black hole is surrounded by an event horizon, for example.More specific types of horizons include the related but distinct absolute and apparent horizons found around a black hole. Still other distinct notions include the Cauchy and Killing horizon; the photon spheres and ergospheres of the Reissner-Nordström solution; particle and cosmological horizons relevant to cosmology; and isolated and dynamical horizons important in current black hole research.Event horizons around Black HolesThe most commonly known example of an event horizon is defined around general relativitys description of a black hole, a celestial object compact enough that no matter or radiation can escape.

This is sometimes described as the boundary within which the black holes escape velocity is greater than the speed of light. While this definition can be made to work, it only does so if the effects of special and general relativity are taken into account. A more accurate description is to note that within this horizon, all lightlike paths (paths light could take), and hence all paths in the forward light cones of particles within the horizon, are warped so as to fall further into the hole. Once a particle is inside the horizon, moving into the hole is as inevitable as moving forward in time (and can actually be thought of as equivalent to doing so, depending on the spacetime coordinate system used).Black hole event horizons are especially noteworthy for three reasons. First, there are many examples near enough to study. Second, black holes tend to pull in matter from their environment, which provides examples where matter passing through an event horizon is expected to be observable.
