Actually, from wherever you are in the universe, it "looks" like you're in the center of the universe. The Big Bang wasn't an explosion in itself, that's the oversimplified version presented by Hollywood.

It's hard to visualize, but imagine that the Universe is a big piece of raisin bread. The raisins represents each galaxy. Now, as the raisin bread expands in the oven, from every point, it appears as though the raisins are going -away- from you--ignoring the edges of the bread, there's no real "center". Also, those raisins who travel the furthest/fastest are ones that are further away from you (if you were in one corner of the bread, the raisin that travels the furthest away would be on the opposite corner).

So from any given point in the Universe, it looks like you're at the center of the universe because space is expanding just like the bread is. Also, space itself is curved, so you can't reach the "end" of the Universe any more than you can reach the ends of the Earth.

Hope this clears up things.

Also, a final point--there is no point that is the center of the universe. The universe itself was the Big Bang (both in space and mass), so the entire Universe was the "center" at one point. That's my amateur understanding anyway. Have a great weekend. :-)
