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.
