Black hole - Simple English Wikipedia, the free encyclopedia
The black hole was the first to be directly imaged (Event Horizon Telescope, released April 10, 2019). [1] [2] A black hole is a region of space-time from which nothing, not even light, can escape. According to the general theory of relativity, [3] it starts existing when spacetime gets curved by a huge mass.

Black Holes | Brilliant Math & Science Wiki
A black hole is a region of spacetime in which the attractive force of gravity is so strong that not even light escapes. As a result, black holes are not visible to the eye, although they can be detected from the behavior of light and matter nearby. The most well-studied black holes are formed from stars collapsing under the gravitational attraction of their own mass, but black holes of any ...
