Why do scientists believe in black holes

they say a black hole is made when a star explodes and the inside gets consents into a incredibly small ball so it gains a muck stronger gravitational field. But that means that the star loses mater because some of it is blasted out so it is denser but with less matter. So how come the black hole then has such a strong gravitational pull that it can pull in light when a much heavier star can only slow light that is coming out of it does that mean that a pound of steel will have a much stronger gravitational pull then 2 pounds of feathers? Explain.

The gravitational field is much more intense because the volume is so small. If you are at the surface of a large star, the grave force is strong, but much of the matter is far away from you. If all the matter is very close, then the grav field will be much bigger. Think of the star made up of millions of balls, all exerting grav force on you.

Scientists believe in black holes because they have found reliable facts that support the formation of black holes. Some of these facts include very strong gravitational force and dying stars. Space telescopes fitted with special instruments have been used to observe the behavior of materials and stars which are very near to black holes.
