ok pandy u got it really close there, but i was actualy thinking "the model of the universe" since at present there is so many different models and the shape is so erf, all over the place which is indescribably beautiful.
the oldest model is used to be drawn on a piece of paper (ie. flat) but nowadays due to 3D modeling it is no longer flat. and you can actualy get a laserlight model of the universe displayed if u really would bother making it out on the computer for display. just choose the one that you like from all the list of theoretical physics model out there.
it is hollow cos well, do i need to say more? and depending on how you look at it, both alien believers and not you must admit life exist in this universe (taken litterally), the full of life can also be taken metaphorically as in ever changing and the amazing and wonderful transformation of the universe.
When someone calls you a lunatic and the first thing that came to mind is a cute, fluffy, white bunny, you know you've played too much RO.
