A black hole is a concentration of mass great enough that the force of gravity prevents anything past its event horizon from escaping it, except through quantum tunnelling behaviour (known as Hawking radiation). The gravitational field is so strong that the escape velocity past its event horizon exceeds the speed of light. This implies that nothing, not even light, inside the event horizon can escape its gravity. It is, however, theorized that wormholes can provide an exit path for energy or matter. The term "black hole" is widespread, even though it does not refer to a hole in the usual sense, but rather a region of space from which nothing can return.
The existence of black holes in the universe is well supported by astronomical observation, particularly from studying X-ray emission from X-ray binaries and active galactic nuclei.

A black hole is a region of space characterised by a massive singularity. An object with infinite mass but devoid of physical dimension. An object so massive that light is prevented from leaving its surface and time is stopped ( event horizon). These areas are created by collapsed massive stars. Jules, lecturer. Australia.

A black hole is a hole in time and space that is created when a super nova collapses on itself and is compressed to such a tiny mass that it explodes. A black hole doesn't let anything escape except for Hawking Radiation which apparently makes the black hole lose mass. Anything that travels faster than light can also escape a black hole.

its a part in the universe where the gravitational field is so intense that not eve light can escape it. happens when a body's density becomes greater than a certain limit.
since light cant escape it, it appears black

A black hole is a collapsed star that is so dense that it's gravitational force is powerful enough to bend light. That is why it is "black."

it is a collapsed massive star that when it collapes in on it self it gravity becomes so great that it is theorized that nothing can escape its gravity not even light.
