Question

What is a black hole? In science and technology

Answer 1

A black hole is a region of spacetime where gravity is so strong that nothing—no particles or even electromagnetic radiation such as light—can escape from it. The theory of general relativity predicts that a sufficiently compact mass can deform.

Answer 2

Black Hole 

Black hole is black planet from which light did not pass. It has highest gravitational force that cant pass light.

how black hole formed?

black form after contraction of sun into white planet.

you can see cycle.

1. reproduction of sun 
2. expansion of sun
3. contraction 
4. then white planet 
5. then black hole.

After black hole every thing become timeless.

Answer 3

Black hole is a astronomical structure which is formed by the supernovae explosion.

when a star with huge mass and small radius reaches the end of its lifetime

it becomes more denser and it makes supernovae explosion.

black holes have huge density due to which it has huge gravatational potential.

At blackhole spacetime bends more.

the escape velocity of black holes is more than the speed of light

even light cannot escape from black holes that is the reason they are black.

nothing can escape from black hole since nothing can travel faster than speed speed of light.

Answer 4

If you are going to outer space, you will find the black hole. Experts described as a part of the space with a high gravitation field that any tangible things cannot escape from it.

Answer 5

Black Hole is a natural phenomena in space . Black has very strong gravitational field.  There is no law of physics work. Even after entering here, the light does not come out.

Answer 6

It is the celestial body that has vert strong gravity. Infect, the gravity is so strong that not even light or electromagnetic waves can escape it. In case you're wondering gravity is a force that a planet or any other body exerts toward an object to attract the object towards the center of the planet. 

Answer 7

A black hole is a region of spacetime where gravity is so strong that nothing, including light or other electromagnetic waves, has enough energy to escape its event horizon. 

Answer 8

A black hole is a region of space where the gravitational pull is so strong that nothing, including light, can escape from it. It is formed when a massive star collapses in on itself, creating a point of infinite density called a singularity. Black holes are invisible to the naked eye but can be detected through their effects on surrounding matter and light. They are also believed to play a key role in the evolution of galaxies and the universe as a whole.

Answer 9

A black hole is a celestial body that, when compressed to a small fraction of its weight, is capable of collapsing and sucking all energy from all other objects in space.

Answer 10

Black holes are the ways to go another universe because this universe is also come from one of black hole and spanding continuously from day one to till today . One day will come when this universe will spend whole energy it will get back to it's origin black hole of which around this universe is circling. But some theories also told us that black holes are spoiler any thing when go inside it that one has destroyed permanently.
