quantumclaustrophobe say: So, picture an ant standing on a huge beach ball. The surface of that beach ball is a 2-d representation of our 3-d universe. Air is added to the beach ball, making it expand. The ant could wander around forever, and never get to an 'edge'.... and, that's similar to our universe - while it's expanding, there's no wall, no edge to where it starts and stops.

Universe is expanding & that means there are no partd of it that don't expand.

Chris say: It's not so much that there is "nothing" beyond that boundary, more that there isn't anything beyond that boundary.
The nature of no-things is a quasi-philosophical question since when we say nothing colloquially we generally are referring to something.
even empty space is something as it has dimensions.
I'm not sure I've helped
