      Technically any object of sufficient size would colapse under its own immense gravity and form a black hole

            Many things we consider objects are mostly not solid, like stars made of Gaz and plasma… And the’res also gaz in the interstellar medium, albeit at very low density. So you still gotta make a hypothesis involving density to determine what will or won’t collapse.

        Isn’t the universe a sufficiently large size? Why is it expanding then? What constitutes an “object”?

          Most of the universe is empty space, and that’s what’s expanding. Empty space doesn’t have any gravitational pull

            Solid objects are 99.999999% empty space, too.

              Yes, but nuclear forces are strong enough to keep the space within from expanding and hold the objects together. It’s in the vast swathes of emptiness between galaxies that we typically see the exansion of space because gravity is too weak there to keep things together.
