What else can I help you with?
Does a giant star have an event horizon?
No. An event horizon is an area where even light cant escape so only black holes have it
Why the event horizon of a black hole stop the light from getting rid of that?
The event horizon is the point of no return around a black hole where the escape velocity exceeds the speed of light. Light cannot escape from beyond the event horizon because the gravitational pull is so strong that even light cannot overcome it. This is why the event horizon appears to "trap" light within the black hole.
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.
Which of these have an event horizon giant black hole white dwarf neutron star?
A black hole has an event horizon, beyond which nothing can escape, including light. Neutron stars also have an event horizon, called the "surface" or "crust," which marks the boundary within which matter is crushed by extreme gravity. White dwarfs, being less massive, do not have an event horizon.
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.
What part of a black hole is the strongest that nothing can escape?
The event horizon. Anything inside the event horizon can't escape.
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.

How is the name black hole related to escape velocity?
The word "black" aptly describes the inability of light to escape - all light and matter that passes the event horizon can only do so in one direction, falling in. The reason is, the escape velocity inside the event horizon is greater than the speed of light, the event horizon itself being the boundary at which the escape velocity is equal to that speed. Outside that horizon, the escape velocity is less than the speed of light, hence it would be possible for light and objects moving at speeds approaching that of light to escape.
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.
Can any thing escape a black hole?
Once anything crosses the black hole's event horizon it will not be able to escape.
What is the escape velocity at the boundary of a black hole?
By definition, the event horizon is a boundary of a black hole at which escape velocity reaches "c", the speed of light. Hence, the event horizon defines a boundary, within which, events can't affect an outside observer; neither light nor matter can escape.
What horizon is formed first?
The apparent horizon is formed first in the evolution of a black hole. It represents the point from which no light can escape, defining the boundary of a black hole's event horizon.
Has gravity so intence even light can not escape it?
Inside the event horizon of a black hole.
