What’s beyond it? What are the theories? I always thought of the universe as a bubble expanding and keeping itself afloat in white space lol

That image misses the point. Space is not a growing bubble. Distance itself is swelling up. One mile (very) slowly becomes two miles and eventually three and so on. It’s not like space is expanding into… other space. Space itself, as in the distances between objects is getting bigger.
