In astrophysics, an event horizon is a boundary beyond which events cannot affect an outside 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 is a boundary around a black hole inside which events cannot affect an outside observer. Event horizon or Event Horizon may also refer to: Event Horizon Telescope, a type of astronomical interferometer; Event Horizon, a 1997 science fiction/horror film; Event Horizon, a 2007 site installation by Antony Gormley
Closed trapped surfaces are a concept used in black hole solutions of general relativity [1] which describe the inner region of an event horizon. Roger Penrose defined the notion of closed trapped surfaces in 1965. [2] A trapped surface is one where light is not moving away from the black hole.
It's possible to keep it active for a longer period, but it would take immense amounts of energy. The wormholes generated by the Stargates are based on the misconception that wormholes in 3D space have 2D (circular) event horizons, but a proper visualization of a wormhole in 3D space would be a spherical event horizon.
