do we know where the center of the universe (place of the big bang) is?

we are at the center of a sphere which the ends are the edges of the *observable* universe, which is not necessarily the edges of the actual (hypothetical, if there were real edges) of the universe, because we are certainly not a helio/geo-centric universe.

with the whole big-bang theory, we might assume (is this correct, this assumption?) that the universe would expand from that origination point equally in all directions, and therefore theoretically discoverable (i.e. the point from which all matter is speeding away from)

if so, do we know where we are relative to that point, and is it in this "sphere" of the observable universe?

**edit** there are a lot of very good points, which require further reading on the internets (i cant afford books, and dont have ready access to a library. Im going to read what i can, and when i have a better understanding, ill come back.

The universe is infinite. It has no center. (as best we can tell)

edit: pre-emptive discussion for the inevitable shitstorm that follows me saying this here.

1) A universe with borders makes no physical sense. We would need to say that physics changes with location, and that's weird

2) Our universe, as best we can measure, is either flat or "saddle" shaped, not shaped like a sphere. Almost definitely flat though. To be specific, we have measured the curvature and feel confident that it is a non-positive value.

3) If a universe is flat, and doesn't have boundaries, it's infinite in size.

A) the universe has always been infinite in size. Even in the big bang, our *observable* universe likely occupied some insanely small volume that was itself a region of some infinite region. Since the big bang, the universe has grown less dense by stretching the space between everything.
