Technically any object of sufficient size would colapse under its own immense gravity and form a black hole
And technically once it has collapsed it isn’t very big anymore!

The universe is not one gigantic solid object

Prove it
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.
