- An event horizon is the boundary surrounding a black hole beyond which no light or other information can escape. It marks the point at which gravitational pull becomes so strong that escape velocity exceeds the speed of light.

5 days ago · Event horizon, boundary marking the limits of a black hole. At the event horizon, the escape velocity is equal to the speed of light. Since general relativity states that nothing can travel faster than the speed of light, nothing inside the event horizon can ever escape beyond it, including light.

In astrophysics, an event horizon is a boundary beyond which events cannot affect an observer. Wolfgang Rindler coined the term in the 1950s. [1] In 1784, John Michell proposed that gravity can be strong enough in the vicinity of massive compact objects that even light cannot escape. [2]
Definition. An event horizon is the boundary surrounding a black hole beyond which nothing, not even light, can escape due to the extreme gravitational pull.
An event horizon is the boundary surrounding a black hole beyond which no light or other information can escape. It marks the point at which gravitational pull becomes so strong that escape velocity exceeds the speed of light.
Event Horizon is the point of no return around a black hole, where the gravitational pull is so strong that nothing, not even light, can escape. In astronautical engineering, the term Event Horizon is used to describe the boundary around a black hole beyond which the escape velocity exceeds the speed of light.
Overview. event horizon. Quick Reference. The surface of a black hole. For a non-rotating black hole, it is a spherical boundary at the black hole's Schwarzschild radius where the escape velocity becomes equal to the speed of light, so no events occurring within it can be seen from outside.
