- | A black hole is a region of space and time where light cannot escape because gravity is so strong. This is possible because [[theories:special_relativity|light always moves with the same velocity]] in the vacuum and therefore cannot move so fast as would be required to escape the black hole. In addition, no object or thing can move faster than with this speed of light, and therefore nothing can escape a black hole. | + | A black hole is a region of space and time where light cannot escape because gravity is so strong.

As a result, no light and nothing else can emerge from the black hole. | As a result, no light and nothing else can emerge from the black hole. | ||
