Assuming the Big Bang is true and the universe expanded from a central entity and it continues to expand, some of it even beyond our current view, is there still a “leading edge” of the expansion and, perhaps, nothing beyond but empty space into which it will eventually expand? Or, does the “container” expand with the expansion? And if so, then what houses the container? - Paul L Hayden
