 Event Horizon (film) - Wikipedia, the free encyclopedia
In the year 2047, a rescue crew (on board the ship Lewis and Clark) investigates the miraculous re-appearance of the spaceship (the Event Horizon) that was supposedly destroyed in a disaster seven years earlier.
As they embark on this mission, they are informed by the ship's designer of the true story behind this "accident." It had in fact not exploded, as was reported, but had been a top secret ship designed to travel faster than the speed of light.
In 2047, faint signals from the lost Event Horizon were picked up on Earth, the ship having ended up on a low orbit around the planet Neptune.

 Beyond the Event Horizon, BlackHols
The region between the stationary limit and the event horizon is known as the ergosphere.
It touches the event horizon at the poles, and stretches out to a distance equal to the radius of the event horizon of a Schwarzchild hole of equal mass (5).
Once the object's angular momentum increased beyond it's mass, the event horizon of the hole would be moving in excess of the speed of light.

 Salon | "Event Horizon"
As Hawking's readers know, the "event horizon" is the border of a fl hole, the horizon of known (and knowable) space, "the boundary of the region of space-time from which it is not possible to escape." It's like a roach motel for reality: Light waves check in but they don't check out.
Before long, we learn that the Event Horizon was part of a secret project to achieve faster-than-light travel by building an "artificial fl hole" at the heart of the ship's engine and creating a "dimensional gateway" to Proxima Centauri.
"Event Horizon" invokes "2001: A Space Odyssey" more than once, not only in its plot about a ship with a mind of its own but also in its best action sequence, in which a spacesuit-less crew member is rescued from a decompressing airlock.

 Event Horizon   (Site not responding. Last check: 2007-10-07)
The event horizon is the gravity field of a fl hole where the space-time is so bent that light cannot escape it.
The event horizon creates a region in space where nothing can escape, if nothing can go beyond the speed of light.
This means that no one outside of the event horizon of a fl hole is capable of observing the breakdown of classical physics inside a fl hole (Hawking 115).

For example, early in the film the Lewis and Clark approaches the Event Horizon through what I guess is the stormy atmosphere of Neptune, with lots of thunder, lightning and turbulence.
The obvious inspiration for ``Event Horizon'' is a much better film, Andrei Tarkovsky's ``Solaris'' (1972), where a space station orbits a vast planet.
But while Tarkovsky was combining the subconscious with the Gaia hypothesis, ``Event Horizon'' uses the flashbacks mostly for shocks and false alarms (hey, that's not really your daughter under the plastic tent in the equipment room!).

 Scientists find black hole's 'point of no return' - MIT News Office
This is strong evidence, the team said, for the existence of a theoretical border around a fl hole called an event horizon, a point from beyond which nothing, not even light, can escape.
"Event horizons are invisible by definition, so it seems impossible to prove their existence," said Remillard.
The idea of using the absence of X-ray bursts to confirm the presence of event horizons in fl holes was proposed in 2002 by Harvard's Narayan and Jeremy Heyl of the University of British Columbia in Vancouver.

The Event Horizon calling to him in his dreams by using his deceased wife is disturbing.
EVENT HORIZON is a pleasing watch, superbly crafted on the technical side, the ship is gorgeously designed, borrowing from the dark, organic look of ALIEN providing the requisite sense of ominous foreboding, adding menacing touches such as teeth seemingly sprouting from bulwark doors and claw-like spikes inexplicably shooting out of the engine room floor.
Event Horizon starts out as a military space hunt set in the distant future and halfway through the film there is a serious plot twist though I won't reveal what it is. For those of you who have not seen this before, you won't know what to expect but that is a good thing.

 Anatomy of A Black Hole
Behind this horizon, the inward pull of gravity is overwhelming and no information about the fl hole's interior can escape to the outer universe.
The event horizon is traced out by "critical" light rays that will never escape or fall in.
Even before the star meets its final doom, the event horizon forms at the center, balloons out and breaks through the star's surface at the very moment it shrinks through the critical circumference.

The event horizon of a fl hole is given by light rays that just fail to escape.
Jacob Bekenstein suggested that the area of the event horizon was a measure of the entropy of the fl hole.
The particles do not come from within the fl hole, but from the “empty” space just outside the event horizon.

 Physicists hope to simulate a black hole event horizon in the lab: 6/00
The boundary around the fl hole (where the light cannot escape) is called the "event horizon." In 1974, Stephen Hawking of Cambridge University theorized that a fl hole is not entirely fl, but could actually emit "flbody," or "thermal," radiation (the kind of radiation that also occurs when the stove is red hot).
Hawking said this radiation has a well-defined temperature that is proportional to the gravitational force at its event horizon.
According to Hawking, if a particle/antiparticle pair is created near the event horizon of a fl hole, gravity will pull one of the particles into the hole permanently, while the other particle (or antiparticle) can escape, or be "radiated," from the fl hole.

 SPACE.com -- Vanishing Gas Confirms Black Hole Event Horizons
The lack of explosions is strong evidence for the existence of a fl hole event horizon, a theoretical boundary into which matter vanishes and cannot escape.
One of the ways to test whether event horizons exist is to show that fl holes don't have conventional surfaces made up of normal matter, said Kimberly Weaver, a scientist from NASA's Goddard Space Flight Center who was not involved in the study.
The idea of using the lack of X-ray bursts to confirm the existence of event horizons has been proposed before, but the current study improves upon earlier research by giving a better account of the conditions that give birth to such explosions.

 SPLICEDwire | "Event Horizon" review
"I created the Event Horizon to go to the stars, but she went much further than that.
But in "Event Horizon," a pathetic, gratuitous gorefest posturing itself as the heir to the "Alien" sci-fi/horror throne, this line belongs to a Sam Neill, a perfectly good actor who gets steady work.
Exploiting the worst of these sci-fi and horror clichés at the same time, "Event Horizon" clearly spent millions on impressive sets (there's a captain's chair that would make James Kirk green with envy), but it only pays lip service to science.

The story revolves around the spacecraft "Event Horizon", a ship designed to achieve faster-than-light travel via a dimensional gateway mechanism capable of breaking barriers of space and time.
Nothing is left to the imagination as we are made to witness all varieties of horror and gore interspersed with inhuman shrieks and loud explosions.
The "Event Horizon" has come back from a place "worse than Hell." The ship is now possessed by some unexplained force of "evil." Wow, that explains it all I guess.

 Event Horizon by Liam Sharp - Official sffworld.com comic book review
Event Horizon Book 1, Volume 1 is a hybrid creation of the written word and art that draws together a plethora of talent both recognisable and new, who attempt to challenge the assumptions and expectations around which the whole industry is based.
Event Horizon isn't all positives though, several of the pieces are too short and at times the 'Mature Themes' tag seems to run away with the contributors, expletives are all well and good in context but for the sheer sake of themselves become worthless.
In conclusion Event Horizon has all the potential to be something very special, this first volume goes some way to fulfilling the ideals set forth at it's inception.
