A "black hole", theorized by Stephen Hawking as a point with gravity so high that the escape velocity would exceed the speed of light. At the time, it was a revolutionary concept; since then, astronomers have gathered evidence of several black holes.
What else can I help you with?
What causes the light from far away galaxies to bend?
If the light from a distance galaxy passes near a massive cosmic object, then the gravity of that object will distort space-time. That will cause the light to bend.
Is black hole celestial body or not?
Yes, black holes are celestial bodies. They are regions in space where gravity is so strong that nothing, not even light, can escape from them. They are formed when massive stars collapse at the end of their life cycle.
What is the basic definition of a black hole?
A black hole is a region of space in which gravitation is so strong that not even light can escape found at the centers of galaxies and also as the final stage after the death of very massive stars.
What is escape volocity?
Escape velocity is the minimum speed that an object must reach to break free from the gravitational pull of a celestial body. This velocity allows the object to overcome the body's gravitational force and enter into space. The specific value of escape velocity depends on the mass and radius of the celestial body.
If gravity waves travel at the speed of light and black holes' escape velocity is much greater than the speed of light then how can gravity waves escape a black hole?
Gravity is not a 'wave', it is a field of curvature of space-time caused by objects with mass. A black hole contains the mass of a star, compressed to the space of a single atom (a singularity), the compression of so much mass into such a small space, is why the black hole has such a powerful gravitational pull.
What object does not reflect light?
A black hole does not reflect light because its gravity is so strong that not even light can escape from it, making it appear totally black in space.
Is so massive that its gravity does not even let light escape?
The object you are describing is a black hole. It is a region in space where gravity is so strong that not even light can escape from it, hence why it appears completely black and invisible to outside observers.
Is there another place in outer space that has gravity?
Yes, every planet and every star has gravity. In fact, every object that has mass, has gravity. Black holes have so much gravity that even light cannot escape.
What object in space has a very strong gravity?
A black hole is an object in space with very strong gravity. It is formed when a massive star collapses, creating a region where gravity is so strong that not even light can escape from it.
How is the force of earths gravity overcome when an object is launched into space?
When on Earth, you can escape if you move away from the Earth at the "escape" speed. Gravity will slow you down and you will reach zero speed at an infinite distance.
What is a blackhole in space?
the astrogeological lightless object in the space having such a powerful gravitational force which does not allow to escape any kind of matter, gas, etc. and not even light, can escape from it and which is formed by the indefinite contraction of heavy and large neutron star under the action of their own gravity.
What is the name for the speed a rocket must reach to escape the earth's gravity?
Escape velocity is the speed that a rocket must reach to break free from Earth's gravity and enter space. It is the minimum velocity required for an object to overcome the pull of Earth's gravity.
Which objects in space emits no light?
black hole as they have a very powerful gravitational pull such that even light could not escape its gravity and fall into it
Is a black hole actually a hole in space?
No, a black hole is not actually a hole in space. It is a region in space where gravity is so strong that nothing, not even light, can escape from it.
What causes the light from far away galaxies to bend?
If the light from a distance galaxy passes near a massive cosmic object, then the gravity of that object will distort space-time. That will cause the light to bend.
How do you describe a black hole?
A black hole is an object that has completely collapsed under the force of gravity into an infinitely dense point. Around it gravity greatly distorts space and time so that, within a certain radius, it is impossible to move outward. Nothing, not even light can escape.
Is black hole celestial body or not?
Yes, black holes are celestial bodies. They are regions in space where gravity is so strong that nothing, not even light, can escape from them. They are formed when massive stars collapse at the end of their life cycle.
