The question "what lies outside our observable universe?" is pretty easily answered with a "the same stuff as inside it, we just can't observe it". The more poignant question is whether the universe as a whole (not just its observable part) has an edge and if so, what lies beyond it. --Koveras (talk) 08:09, 7 April 2014 (UTC)

The parts of universe which are not observable due to speed of light looks the same as the ones we can observe, sure. Just bigger. But there is nothing in physics saying there can't be something even more "outside". In fact, some theories consider it probable. And what can be THERE? Anything. Dragons. Possibly literally. Unfortunately, according to current physic, we can't PROVE something outside exists, much less look at it. -- Hkmaly (talk) 10:21, 7 April 2014 (UTC)

What's the setting of the first panel? Given the cosmological context, could it be a reference to the Wood between the Worlds from the Narnia series? 108.162.219.29 10:57, 7 April 2014 (UTC)

Someone please rewrite my shunted in assertion about the aforementioned wood. There's a reason for the setting in the first panel, I just can't think of a better place to put it in the explanation. 108.162.244.6 11:43, 7 April 2014 (UTC)

The tire swing also evokes the cosmology field in itself; accepted theories keep changing like the swing, endlessly being replaced by the next one. 14:18, 7 April 2014 (UTC)
