What does it even expand into like in terms of displacing the presumably “Nothing” that previously existed or didnt exist when the universe expanded and should have displaced or subsumed it?

I’ve seen it descrived as getting inflated, as in, every single point of it getting further apart.
This makes it so there’s no “nothing” to displace, there’s just more new stuff.
Not new stuff, just new space between all the stuff that’s already there.
