[b]A blackhole is formed when a star collapses on its self due to its gravity being more than the forces of nuclear fusion in its core. The gravity of a blackhole is so great that anything even light can not escape its pull,hence it appears dark.  Theoritically,anything can become a blackhole,you only have to 'compress' to or beyond its schwarzschild's radius. For one to form a blackhole from Earth,he has to compress the earth to a sphere of radius 9mm(thats about as big as a 1 naira coin). And the sun to sphere of radius 300Km.
