:O, when I was small I was always scared about what was beyond our universe, the thing thast scared me is when people said that the universe goes on FOREVER, it doesn't stop anywhere, that is a bit freaky though ^^, lol, when I was like 9 or so I even cried about it, I felt useless...
But sheesh, I don't know where all the space comes from to fit in those big stars
But you know what I think? I think that we're all part of some HUGE kid's own universe, we're like his science project, so we're all just made to give him some marks, not that we are seeable to him, so one atom of his kind is as big as that huge star like thing, lol.
Just kidding, my imagine is very weird indeed...
