A Black Hole is a region in space where the pulling force of gravity is so strong that light is not ablo to escape. The strong gravity occurs because matter has been pressed into a tiny space. This compression can take place at the end of a star’s life. Some black holes are a result of dying stars. Because no light can escape, black holes are invisible.
