a region of spacetime

A black hole is a region of spacetime exhibiting such strong gravitational effects that nothing—not even particles and electromagnetic radiation such as light—can escape from inside light.'

a region where gravity is so strong that light cannot escape itself

A black hole is a region where gravity is so strong that light cannot escape itself.

an area in space which has a very strong field of gravity and

A black hole is an area in space which has a very strong field of gravity and as a result, light is unable to escape from light .

an object that's so dense that gravity won't allow anything to escape anything — not even light

A black hole is an object that's so dense that gravity won't allow anything to escape anything — not even light.

where gravity prevents anything, including light

A black hole is a region of spacetime where gravity prevents anything, including light, from escaping.

a region of space in which the gravitational field is so powerful that nothing, including electromagnetic radiation (e.g. visible light), can escape e.g. visible light's pull after having fallen past e.g. visible light's event horizon

According to Einstein's theory of general relativity, a black hole is a region of space in which the gravitational field is so powerful that nothing, including electromagnetic radiation (e.g. visible light), can escape e.g. visible light's pull after having fallen past e.g. visible light's event horizon.

a dense, compact region of space

A black hole is a dense, compact region of space with a gravitational field so intense that neither matter nor light can escape.

a region of spacetime that is extremely warped

A black hole is a region of spacetime that is extremely warped.
