Oct 16, 2023 · In general relativity, an event horizon is the part of a black hole where light cannot escape. Imagine the black hole to be like a ball that you could see in a large spot of emptiness.
Sep 7, 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 general relativity, an event horizon is the part of a black hole where light cannot escape. Imagine the black hole to be like a ball that you could see in a large spot of emptiness. The event horizon would then be an outer bubble that surrounds that ball, the space between the ball and the larger bubble would be the event horizon.
Mar 3, 2023 · The event horizon is a boundary that marks the outer edge of black holes. It is the point at which nothing, not even light, can escape.
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]
An event horizon can form around a gravitational singularity where its gravitational pull exceeds the ability of any form of mass or energy, including light, to escape. Outside the event horizon, there is a region where light is bent because of the gravitational pull.
