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]
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.

Event horizon, a boundary in spacetime beyond which events cannot affect the observer, thus referring to a black hole's boundary and the boundary of an expanding universe; Apparent horizon, a surface defined in general relativity; Cauchy horizon, a surface found in the study of Cauchy problems; Cosmological horizon, a limit of observability
A plot summary is a brief description of a piece of literature that explains what happens. In a plot summary, the author and title of the book should be referred to and it is usually no more than a paragraph long while summarizing the main points of the story. [40] [41]
At some point, a plot summary is likely to be edited by someone else; editors do not own their golden prose. At the same time, changes should be closely monitored. Well-meaning editors may be unaware of prior discussions or conventions regarding plot summary length. Plot bloat is thus a serious problem.
In general relativity, a naked singularity is a hypothetical gravitational singularity without an event horizon.. When there exists at least one causal geodesic that, in the future, extends to an observer either at infinity or to an observer comoving with the collapsing cloud, and in the past terminates at the gravitational singularity, then that singularity is referred to as a naked ...
Event Horizon is a 1997 science fiction horror film directed by Paul W. S. Anderson and written by Philip Eisner. It stars Laurence Fishburne, Sam Neill, ...
Wolfgang Rindler (18 May 1924 – 8 February 2019) was an Austrian physicist working in the field of general relativity where he is known for introducing the term "event horizon", Rindler coordinates, and (in collaboration with Roger Penrose) for the use of spinors in general relativity.
