What we can and possibly will observe at some point in time. That in itself doesn't say anything on how big the universe really is and if it could be infinite.
Something I heard recently: The unobservable universe is to the observable universe as the observable universe is to a marble.
I pulled the covers over my head at that point.
The ratio that I heard was to a proton, but we're likely splitting hairs at this point!
