| β | The comic seems to be recursive, where one Cueball's bubble universe contains another Cueball doing the same thing, blowing bubbles, seeming to contain the whole scene within one of the bubbles in the original scene. | + | The comic seems to be recursive, where one Cueball's bubble universe contains another Cueball doing the same thing, blowing bubbles, seeming to contain the whole scene within one of the bubbles in the original scene. This may reference cosmological models like the {{w|Big Bounce}}, in which a new universe emerges from a previous universe. A similar view is in the "{{w|turtles all the way down}}" view of the universe, but here the universe is suspended in bubbles, and those bubbles suspended in a universe suspended in bubbles, "all the way down" (or at least one layer down). |
| β | The title text claims this theory "Finally unifies cosmic inflation and regular inflation." Cosmic inflation refers to the expansionary phase of the universe shortly after the Big Bang; this would explain why that happened with the simple proposition that it was a bubble and inflated like regular bubbles do. | + | The title text claims this theory "Finally unifies cosmic inflation and regular inflation."

(Ignoring various issues β like the sheer size of the universe, at least in terms of its own scale.) It also makes a pun on special and general relativity, and how they've been hard to merge for a long, long time; the result of which is known as the grand unified theory. |

| + | The scene looks like it could be part of an infinite recursion. The two Cueballs and grounds are similar but not identical, a self-similarity (also known as expanding symmetry or unfolding symmetry) common in {{w|Fractal|fractals}}. | ||
