In general relativity, a surface in spacetime that marks the boundary of a region from which light rays cannot escape to infinity at a given moment, often associated with black holes and distinct from the event horizon.

  1. Apparent horizonC2formal

    In general relativity, a surface in spacetime that separates regions where light can escape to infinity from those where it cannot, defined locally by the behavior of outgoing light rays.

    • The apparent horizon is a key concept in the study of black holes.
    • Physicists use numerical simulations to locate the apparent horizon in a dynamic spacetime.
    • The formation of an apparent horizon signals the presence of a black hole.
