Can light escape black holes?

No. The escape velocity of a black hole is greater than the speed of light.


Is escape velocity of light infinity?

Not at all. It would take an infinitely large mass to produce an infinite escape velocity, and no such infinite mass exists. Furthermore, the escape velocity for any object is the same no matter what is trying to escape, so light does not have its own escape velocity. This question presumably concerns black holes. Light does not escape from black holes because the escape velocity is greater than the speed of light. The speed of light is not infinite, it is 300,000 kilometers per second.


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.


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.


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.


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.


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 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 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


What is the escape velocity at the event horizon of a black hole?

The escape velocity at the event horizon of a black hole is the speed at which an object must travel to break free from the black hole's gravitational pull. It is equal to the speed of light, which is approximately 186,282 miles per second.


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.


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.
