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]
A horizon is a boundary in spacetime satisfying prescribed conditions. There are several types of horizons that play a role in Albert Einstein 's theory of general relativity : Absolute horizon , a boundary in spacetime in general relativity inside of which events cannot affect an external observer
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.

Upon boarding the Event Horizon, the crew finds evidence of a massacre. As they search for survivors, the ship's gravity drive activates and briefly pulls Justin into a portal while also causing a shock wave that damages the Lewis and Clark. The crew are forced to board the Event Horizon while Justin emerges in a catatonic state.
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
Also apophthegm. A terse, pithy saying, akin to a proverb, maxim, or aphorism. aposiopesis A rhetorical device in which speech is broken off abruptly and the sentence is left unfinished. apostrophe A figure of speech in which a speaker breaks off from addressing the audience (e.g., in a play) and directs speech to a third party such as an opposing litigant or some other individual, sometimes ...
Both of these facts would also be true if we were considering a set of observers hovering outside the event horizon of a black hole, each observer hovering at a constant radius in Schwarzschild coordinates. In fact, in the close neighborhood of a black hole, the geometry close to the event horizon can be described in Rindler coordinates.
The coverage of a fictional work should not be a mere plot summary. A summary should facilitate substantial coverage of the work's real-world development, reception, and significance. This means that an article about a work of fiction or elements from such works should not solely be a summary of the primary and tertiary sources , they should ...
