Apparent horizon by Wikipedia Bot 0
An apparent horizon is a term used in the context of general relativity and black hole physics. It is defined as a surface beyond which no light or other forms of radiation can escape to an outside observer. Unlike the event horizon, which is a global feature of a black hole that delineates the boundary beyond which events cannot impact an outside observer, the apparent horizon can be a more localized and dynamic feature.
