A black hole.
Imagine you are standing on the surface of the earth. You toss a ball up into the air at 100 miles an hour. It arcs upward, then falls back to the earth. Now you shoot the ball up at 1000 miles an hour. It goes up and up and up, thousands of feet, but eventually arcs over and falls back to earth.
So now you get serious, and fling the ball up at 17,000 miles per hour. It leaves the earth, and goes into orbit.
So you get another ball, and this time you fling it 25,000 miles an hour. That velocity exceeds earth's "escape" velocity, such that the ball sails up and away and never returns to the earth again, unless by accident as it drifts around the sun it.
So if we shrink the earth down, but keep the same mass, surface escape velocity becomes larger. Maybe the same earth mass compacted into a sphere 4000 miles in diameter would have an escape velocity of 50,000 miles per hour. Keep shrinking the earth down, until it is the size of a marble, and escape velocity would exceed 186,300+ miles per second. This number is special, in that not even light can move that fast.
So that is what a black hole is--a mass whose escape velocity exceeds the speed of light. Space is warped so much these objects are essentially "pinched off" from the rest of the universe.

∙ 13y agoThe neighborhood of a black hole. Not everywhere around it,
but closer to it than the "event horizon".
awsome isn't it and pritty unbelievable don't you think?

What is an area where gravity is so strong not even light can escape?
That is called a black hole.
What is the name for an area in space where gravity is so strong that it acts like a vacuum cleaner and sucks in energy and matter?
Blackhole

a black hole
What would be easier for us to do in a low-gravity area Or in a high-gravity area?
low-gravity. zero-gravity however could have devastating effects on a human body.
Where the red light area in tirupur?

That is called a black hole.
What is an area of space with gravity so strong that it traps light?
A black hole has gravity so heavy it traps light.
Black hole?
If enough matter gets concentrated into an area that is small enough, gravity can become so strong in the immediate surroundings that nothing can escape from that area. That is called a "black hole". For more information, read the Wikipedia article with the title "black hole".
What is 'black-hole'?
If enough matter gets concentrated into an area that is small enough, gravity can become so strong in the immediate surroundings that nothing can escape from that area. That is called a "black hole". For more information, read the Wikipedia article with the title "black hole".

Why blackholes have high gravity?
Blackholes are not really holes, it is where a huge amount of matter has come together and has been concentrated into a very small area. Mass is related to gravity, any mass has gravity, but you don't really notice it until you have enough mass like that of the earth. There is so much mass at the centre of a black hole that even light cannot escape it's immense gravity - that's why it's black.
Where is there An area of no light and matter with gravity?
Probably nowhere. You may be confused with the idea of the "black hole", an object so massive that light cannot ESCAPE. But light - and any other matter - can certainly fall IN, and the radiation within the black hole is incalculable. The idea of the "black hole" simply means that our understanding of physics is inadequate to the task of describing what happens in an area of extreme mass. We DO NOT KNOW what happens there.
Can you escape the earth gravity by going to the moon?
No. If you are on the moon, then the moon is the dominant gravitational body in your area, but the moon still orbits Earth and so is still very much under the influence of Earth's gravity.
What exactly is a black hole?
A black hole is an area of such immense gravity that nothing—not even light—can escape from it. Black holes form at the end of some stars' lives. The energy that held the star together disappears and it collapses in on itself producing a magnificent explosion. :)

Area with gravity so strong it traps light?
Known as black holes. A black hole is a singularity (like the one believed to create the universe in the Big Bang Theory) that was caused by a high-mass star that erupted in a violent super nova, which, eventually collapsed into itself so fast that it started to bend the fabric of space and time, with a gravity that traps everything from light to energy.
Why do some space bodies have irregular shapes?
Bodies that are small and light (examples: moons of Mars) have low gravity and tend to have irregular shapes. Above a certain size, however, gravity is strong enough to overcome the strength of rock, forcing the body into a spherical geometry that minimizes surface area-to-volume ratio.
