I probably think about this more than anything else when I'm bored because it stretches my mind and my imagination...and I just find it interesting. I have my own theory as to what exactly the "edge" of the universe is, and have my own ways of explaining it. I would just like to hear other people's ideas and thoughts because I'm always looking for insight. PLEASE leave "religion vs science" out of this one, I don't care how it all "Started", I just want to hear what you think. I'll post my ideas after this gets a few replies.
