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.

Technically any object of sufficient size would colapse under its own immense gravity and form a black hole
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.
And technically once it has collapsed it isn’t very big anymore!
The universe is the biggest object there is and it’s not collapsing tho…
The universe is not one gigantic solid object

I mean I’m mostly liquid and I bet so is the dog
Prove it
