Hey "anonymous scientist", take it easy on 3. He's just trying to take an interest, so don't disparage him for his minimal lack of knowledge. He is obviously not a graduate and is obviously here because it interests him.
3, you did bring up a few interesting tidbits about the whole space-time thing. The point at at which the "singularity event" (the big bang) occured is to some the center of the universe. In light of that fact, questions are often revisited by some astronomers and physicists about the bounds of the universe. Where does it end, and what is contained in an area with no particulate matter? In order for there to be a singularity event, there must be areas outside of that event containing no matter (not even any subatomic particles!). But what does that look like? How does it behave physically?
Frankly, it is all far above me.
For Yevon:
Excuse my egregious ignorance, but what is "Loki"?
