The current model of the universe, posited by the Man in the Bowler Hat. This model posits that all these alternate worlds, some extremely similar and others wildly different, are all wrapped around the main dimension humans live in, "like a big pile of dirty laundry, or like taffy, kinda."

This model is often controversial because it explains unfinished worlds (like Florida or the Back Rooms) not as worlds that never developed all the way, but as once-complete places now shattered into barely comprehensible nowhere.
