Question

what is black hole??​

Answer 1

Black Hole:

A cosmic entity which has a gravitational force so strong,even light can't escape from it

Discovery:

The term 'Black Hole' was coined by John Wheeler

Structure:

Black Hole is divided into two regions,

An event horizon and a singularity

Event Horizon:

The boundary of the black hole,is further differentiated into outer event horizon and inner event horizon.

If any particle should enter this,can never return

The gravitational force is experienced here

Singularity:

It is that part of a black hole,where all matter is condensed in.

Fun fact:

If a human jumps into a black hole and eventually lands in the singularity of black hole,he is likely to experience wave motion

Answer 2

Answer:

Black hole is an area in space that nothing, not even light, can escape from, because the force that pull objects in space towards each other(gravity) is so strong there.
