A black hole is a cosmic body with a very high density and concentration of matter, that even light cannot escape from it, which is an incredible speed (300,000 km / s).
The presence of these objects affects their environment in extreme ways, such as the deformation of space-time.

take a picture of a black hole M87.
A black hole is formed whenever a sufficient amount of matter condenses…
