Answer: a definition of the term black hole</h2>
This text is clearly a definition of the term black hole, made by the American astrophysicist Neil deGrasse Tyson.
However, the discussions about this subject are not new, since Einstein's theory of relativity already defined what a black hole is.
In this sense, a black hole is described as a "singularity" that consists of <u>a region of the space in which the density of matter tends to infinity.</u>
Although this is hard to find possible for classical physics; following what relativity establishes:<em> bodies within a gravitational field follow a curved space path. Then the more a body enters the black hole, the more curved the space will become, until, in the center, it will become infinitely curved. </em>
