I think "The Force" is a phenomenon that is unique to the galaxy in which Star Wars is set. Obi-Wan said that it "binds the galaxy together," not the whole universe. But in TLJ, Luke did say "the universe." Maybe he was just making an assumption there, or just talking metaphorically or something.
It would be interesting if some Jedi went on an extra-galactic expedition, and they found that their Force sensitivity and abilities diminished more and more, as they got further away from the galaxy and lost their connection with that "energy field."
