In truth, the phrase "in the universe" is not accurate to describe what Beckett is doing with the binary pairing of these characters. All current Beckett scholars see these pairings as a dramatic embodiment of the two parts of the human condition: the body as part of the physical world, and the mind as part of the abstract or mental perception of the world. The most obvious example of this duality is in the details of Didi's attention to hats (mental) and Gogo's attention to boots and food (the body). Looking closely at such details as eating, exchanging hats, handling of shoes, and scratching of head has shown how these elements have been carefully chosen. When combined with the master-slave relationship of Pozzo and Lucky, we discern that the mind is, or thinks it is, the master and the body is the mind's slave. There may very well be large "binary oppositions" in the "universe," but Beckett's work seldom, if ever, concerns itself with what these oppositions might be. He is much more concentratedly considering Man's condition, both his "existence" and his inevitable cessation, all a mystery in that their "purpose" is inexpressible. As Becket puts it, he is spending his life "effing the ineffable."
