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 else can I help you with?
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.
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.
How are the mass of the body and escape speed related?
The greater the mass of the planet, the greater will be the escape velocity.
What does it mean when light could not escape?
In the case of a black hole, the gravitational pull of the black hole is greater than the speed of light. Which means that the light is not fast enough to escape the gravitational pull of the black hole.
Will the mass change at a very high speed compared the speed of light?
Yes. According to the extended theory of relativity, mass will increase as an objects speed increases. The closer the object's speed gets to the speed of light, the greater its mass will be and a greater force will be required to continue to accelerate it.
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.
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.
To escape from a planet's an object muct reach a speed called the?
To escape from a planet's gravitational pull, an object must reach a speed called the "escape velocity." This velocity depends on the mass and radius of the planet from which the object is trying to escape.
How do you make a 50kg satellite travel at 95 percent light speed around the Earth?
1) Mankind doesn't currently have the technology required to make anything (except atoms and subatomic particles) move at near the speed of light.2) An object moving at 95% of the speed of light won't be a satellite of anything, except perhaps a black hole - at that speed, it would quickly escape. At a speed of about 11 km/sec, an object would have enough speed to escape Earth's gravitation - compare this to the speed of light, which is about 300,000 km/sec.
Is escape velocity bigger than orbital velocity?
Yes, escape velocity is greater than orbital velocity. Escape velocity is the minimum speed required for an object to break free from the gravitational pull of a celestial body and move into space. Orbital velocity is the speed required for an object to maintain a stable orbit around a celestial body.
Can the speed of light escape a black hole?
No, the speed of light cannot escape a black hole because the gravitational pull of a black hole is so strong that even light cannot escape it.
