      I think by definition we can’t know that!

      Nope. There are theories that it’s nothing and theories that space itself loops back on itself so you just end up where you started, but no one really knows.

      If it’s beyond the field of our vision though we have no way of seeing it, so we’ll never know for sure.

      Nope, and neither does anyone else.

      No, no one knows because there’s a limit to what we can see. The universe is (only!) 14 billion years old, and light can only travel at a fixed speed, so there’s only so far the light can have traveled since the beginning of our universe, and so only so much we can see.
      What’s outside that might look a lot like our universe, or it might be very different, unless we find a way of travelling faster than light we’ll never be able to know.
