The escape velocity of a black hole is equal or greater than the speed of light, so light cannot escape
The escape velocity from a black hole is equivalent to the speed of light. This is why nothing can escape from a black hole - not even light.
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.
The escape velocity reaches the speed of light at the Schwarzshild radius.
At the point of the event horizon, the pull of gravity is so strong that the escape velocity reaches the speed of light. As such, when light reaches this point, it cannot escape.
According to the particle theory of light, light is made us of particles called photon. Black hole has very high gravity. Its escape velocity being more than that of speed of light, light is attracted towards it and it even cannot escape by lunizah: black holes attract every thing even the light because they have a very strong attractive force and that's the reason why black holes attract light!! ^_^
Nothing can escape a black hole, not even light.
No. The escape velocity of a black hole is greater than the speed of light.
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.
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.
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.
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.
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.
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.
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.
It is called the Schwarzschild radius
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.
The escape velocity reaches the speed of light at the Schwarzshild radius.
At the point of the event horizon, the pull of gravity is so strong that the escape velocity reaches the speed of light. As such, when light reaches this point, it cannot escape.
