Black hole is defined as a region in space-time where the space-time is highly curved, meaning that the gravitational force is so large that even EM radiation is unable to escape its gravitational pull. Black holes are usually found in the centre of galaxies. Black holes are formed when stars having 8-13 or more solar mass exhaust their fuel i.e., Hydrogen, which then implode.
