Respuesta :
The supergiant stars are considered as the biggest stars in the universe. They can be thousands of times larger than the Sun and can exhibit a mass up to 100 times more. In the case when the supergiants run out of fuel or hydrogen they give rise to a supernova, and then either turn into a black hole or a neutron star.
A neutron star refers to a very dense but little star, comprising neutrons and emerges as the core of the dead supergiant.
A black hole refers to a location in space, more accurately in time-space, which is most generally known for its drastic gravitational influence and for its dark color.
The object will form when a supergiant runs out of fuel is a black hole or a neutral star.
