What is the name for the boundary around a black hole beyond which events cannot affect the observer?
The "boundary" you're probably thinking of is called the event horizon. Past this point, the escape velocity of the black hole exceeds the speed of light, meaning nothing, including light, can escape it.
Who coined the term event horizon?
The term "event horizon" was coined by physicist John Michell in 1783 to describe a boundary in space-time beyond which light and matter cannot escape the gravitational pull of a black hole.
What are the two parts of the black hole?
The two parts of a black hole are the event horizon and the singularity. The event horizon is the "surface" of the black hole, and is imaginary. The event horizon's appearance is caused by the bending of light. The singularity is a point of space where everything that gets sucked in is crushed to about the size of an atom.
Does a white dwarf have a event horizon?
No, white dwarfs do not have an event horizon. Event horizons are a characteristic feature of black holes, where the gravitational pull is so strong that not even light can escape. White dwarfs are dense stellar remnants, but they do not have the extreme gravity needed to form an event horizon.
How is the term 'event horizon' defined?
The event horizon is a "point of no return"; anything within the event horizon can't get out, even at the speed of light.An event horizon is the "surface" of a black hole. It is the line that is crossed right where the chaos stops and the actual hole begins. it is theorized that beyond this horizon, all of the laws of physics cease to exist. A single hydrogen atom becomes a billion mega-ton hydrogen bomb. an entire planet fits on the head of a needle, that sort of thing.In general relativity, an event horizon is a boundary in spacetime, most often an area surrounding a black hole, beyond which events cannot affect an outside observer. Light emitted from beyond the horizon can never reach the observer, and anything that passes through the horizon from the observer's side appears to freeze in place, with its image becoming more redshifted as time proceeds.

What planet has a event horizon?
No planet has an event horizon. A black hole has an event horizon; it is the radius within which light cannot escape.
When was Event Horizon released?
Event Horizon was released on 08/15/1997.
What was the Production Budget for Event Horizon?
The Production Budget for Event Horizon was $60,000,000.

What is the duration of Event Horizon film?
The duration of Event Horizon - film - is 1.58 hours.
When was Event Horizon - film - created?
Event Horizon - film - was created on 1997-08-15.
How much money did Event Horizon gross worldwide?
Event Horizon grossed $26,673,242 worldwide.
What is the event horizon in a black hole?
That is the "point of no return". Within the event horizon, gravity is so strong that anything that crosses the event horizon can't get out, even if it moves at the speed of light.
How much money did Event Horizon gross domestically?
Event Horizon grossed $26,673,242 in the domestic market.

Is there any way to escape a black hole?
Don't go near it. Once you are within the event horizon, there is no hope. In fact you would be dead long before crossing the event horizon. Tidal forces would have turned you and your vehicle into a kind of space spaghetti.
