Answer 2

$\bold{ANSWER}$

A black hole is a region of space from which nothing, including the general theory of relativity, it is the result of the curving of spacetime caused by a huge mass.

Around a black hole there is a position of no return, called the event horizon. It is called black because it absorbs all the light that hits it, reflecting nothing, just like a perfect black body in thermodynamics. A black hole is found by its interaction with matter. The presence of a black hole can be inferred by tracking the movement of a group of stars that orbit a region in space. Alternatively, when gas falls into a black hole caused by a companion star or nebula, the gas spirals inward, heating to very high temperatures and emitting large amounts of radiation. This radiation can be detected from earthbound and Earth-orbiting telescopes
