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.

How does the escape velocity from a black hole compare with the speed of light?
The escape velocity of a black hole is equal or greater than the speed of light, so light cannot escape
Can light escape black holes?
No. The escape velocity of a black hole is greater than the speed of light.
If light does not escape a black hole does it just sit there?
Light continues to circle around the 'black hole' in what is called the 'Schwartchild radius before disappearing into the event horizon'. This is how that scientists are said to find the 'black holes'; they find the bright 'circles' with a black hole in it. light cannot escape a black hole because the escape velocity (the velocity needed to escape the gravitation pull of a celestial body) of a black hole exceeds the speed of light.
What of a black hole is the radius from a black hole at which the escape velocity is approximately equal to the speed of light?
It is called the Schwarzschild radius
Is it possible for something to have an escape velocity equal to light?
No light is the fastest possible. Nothing escapes the velocity of light. ==================================== Sure. The escape velocity at some appropriate distance from a black hole is equal to 'c'. That's why the hole is black. The exact value of the distance depends on the hole's mass.
What excatly is a black hole?
A black hole is a region in space-time with very strong gravitational pull that even light cannot escape from it. The ESCAPE VELOCITY is greater than SPEED OF LIGHT.
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.
Why is the term black hole appropriate?
The term 'black hole' is particularly appropriate in its application to the astrophysical phenomenon of the same name due to the property of the escape velocity exceeding the speed of light. This means that no light or matter escapes a black hole.
What does the black hole?
The black hole represents a crust in the space which swallows anything that passes through it. Even light cannot escape from a black hole! There is a particular radius for a mass to become a black hole when it is squashed. This is known as the Schwarzschild radius and for the body to become a black hole, the escape velocity must equal or exceed speed of light!
An object that has an escape speed greater than that of light is a?
A black hole has an escape velocity of the speed of light, at least theoretically. Oddly, though, each galaxy has a black hole and we can detect them because they throw off massive amounts of energy. If the escape velocity is greater than the speed of light, then no light or energy of any kind should escape. So black holes are not quite the perfect consumers of everything.
Can energy escape thorght a black hole?
No, nothing can escape a black hole
Can wind escape a black hole?
No! Not even light can escape the black hole!
