| − | [[Cueball]] and the curious [[ | + | [[Cueball]] and the curious [[Science Girl]] walk through a landscape with trees in the background and with many small pools of water. The setting of trees interspersed with these many small pools resembles the {{w|Wood between the Worlds}}, a meta-verse described in C.S. Lewis's ''{{w|The Magician's Nephew}}''; each pool leads into a different universe — one of these is ours, another is {{w|Narnia}}, and Charn (the world of Jadis the {{w|White Witch}}) is also visited through these pools. |
| − | + | Science Girl asks about the time before the {{w|Big Bang}}. Cueball says he thinks there was no time before — which is implied by most forms of the Big Bang theory. But then they happen upon a {{w|cosmologist}}, [[Megan]], on a swing who has several other theories about the universe. | |
Simply put, the tire swing is a symbolic representation of our universe. Scientific observations tell us that both space and time began with the Big Bang ~13.8 billion years ago. We don't know if there was such a thing as "before" the universe, or what that might be. | Simply put, the tire swing is a symbolic representation of our universe.

The first 6 panels reference ongoing speculation about where the universe came from and why it even exists in the first place. The last two panels relate to recent observations of the {{w|accelerating universe}} in which galaxies are now receding from each other at higher and higher speeds, due to {{w|dark energy}}. | The first 6 panels reference ongoing speculation about where the universe came from and why it even exists in the first place.

| − | The swing itself is likely a reference to the {{w|Cyclic Model}}, where the universe expands from a Big Bang, then contracts back in on itself under its own gravity for a {{w|Big Crunch}}, before bouncing outward again in another Big Bang, and repeating the whole process. On the other hand, the swing is accelerating as the universe — so it may also be a reference to the entire universe. We are all "trapped" on this swing — and it's accelerating!

On the other hand, the swing is accelerating as the universe — so it may also be a reference to the entire universe. We are all "trapped" on this swing — and it's accelerating! For the layman (and most scientists as well) cosmology is ''pretty confusing'' as Science Girl states at the end, to which the cosmologist just replies ''Wheeeee!'' and enjoys her ride with this accelerating swing/universe. |

The title text references questions about the {{w|shape of the universe}} and what could lie "outside" of it. By the current understanding on physics laws, we can't see outside of the {{w|observable universe}}, but it's likely that the universe is bigger than this observable universe and uniform on large scale. Even though nobody can leave our own universe, Megan bets that such unknown worlds do exist - because this universe is here, and it must have come from somewhere — like her tire. | The title text references questions about the {{w|shape of the universe}} and what could lie "outside" of it.

| − | + | Science Girl is seen later in conjunction with a tire swing in [[1659: Tire Swing]]; maybe she is preparing to become a cosmologist herself. Also this may explain from where the tire came from... | |
