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. --[[User:Koveras|Koveras]] ([[User talk: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. -- [[User:Hkmaly|Hkmaly]] ([[User talk:Hkmaly|talk]]) 10:21, 7 April 2014 (UTC)
