Read the excerpt from Neil deGrasse Tyson’s “Death by Black Hole.” Black holes are regions of space where the gravity is so high that the fabric of space and time has curved back on itself, taking the exit doors with it. Another way to look at the dilemma: the speed required to escape a black hole is > the speed of light itself. . . . light travels at exactly 299,792,458 meters per second in a vacuum and is the fastest stuff in the universe. If light cannot escape, then neither can you, which is why, of course, we call these things black holes. Which of the following features would best enhance the reader’s understanding of this excerpt?
a photograph of a black hole
a demonstration of the speed of light
an interactive animation of a black hole
a definition of the term black hole

Answer: a definition of the term black hole

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 a region of the space in which the density of matter tends to infinity.

Although this is hard to find possible for classical physics; following what relativity establishes: 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.

What is the black hole in astronomy?

A black hole is a celestial body that has an intense gravitational field, in such a way that nothing can escape its force, not even light itself. For this gravitational field to occur, a large amount of extremely concentrated mass is required.

In this way, one way to be able to exemplify the black hole is by defining it, and in 2020 the first photo of the black hole was taken, which would be great to exemplify as well.
