| Event horizon | Aerospace | 1: The boundary of the region around a black hole from which nothing can escape once crossed. (references) | |
| 2: The distance from a black hole within which nothing can escape. In addition, nothing can prevent a particle from hitting the singularity in a very short amount of proper time once it has entered the horizon. In this sense, the event horizon is a "point of no return." See Schwarzschild radius. (references) | |||
| Event horizon | Geology | The boundary or "point of no return" of a black hole. Nothing -- neither particles nor photons (i.e., electromagnetic radiation) -- can escape from inside the event horizon. To escape would require a speed greater than that of light, which is not allowed. (references) | |
| Event horizon | Physics | The radius that a spherical mass must be compressed to in order to transform it into a black hole, or the radius at which time and space switch responsibilities. Once inside the event horizon, it is fundamentally impossible to escape to the outside. Furthermore, nothing can prevent a particle from hitting the singularity in a very short amount of proper time once it has entered the horizon. In this sense, the event horizon is a "point of no return". (references) | |
