What is a black hole event horizon?
Jun 1, 2024 · 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. In 1784, John Michell proposed that gravity can be strong enough in the vicinity of massive compact objects that even light cannot escape.
Mar 3, 2023 · The event horizon is the spherical outer boundary of a black hole loosely considered to be its "surface." It is the point, according to NASA, that the gravitational...
Apr 30, 2024 · An event horizon is a boundary in spacetime beyond which events cannot affect an observer. It is most commonly associated with black holes, where the gravitational pull is so strong that not even light can escape.
Oct 13, 2009 · What an event horizon is – its behavior – is described by applying the equations of Einstein’s theory of General Relativity (GR); as of today, the theoretical predictions concerning event...
Sep 8, 2020 · A black hole is an astronomical object with a gravitational pull so strong that nothing, not even light, can escape it. A black hole’s “surface,” called its event horizon, defines the boundary where the velocity needed to escape exceeds the speed of light, which is the speed limit of the cosmos.
Event Horizon. This is what makes a black hole black. We can think of the event horizon as the black hole’s surface. Inside this boundary, the velocity needed to escape the black hole exceeds the speed of light, which is as fast as anything can go. So whatever passes into the event horizon is doomed to stay inside it – even light.
