It wasn’t matter that “banged”, it was space-time itself. We observe space expanding, and when we extrapolated backwards eventually we found the point when space-time (not necessarily the stuff inside it) was just a single point, and we called that point “the big bang”. That’s just what the current math says of course, but because of the rate of expansion and the speed of light, we can only observe so much of the universe, past and present. Even when we observe far out and way back to soon after the big bang, we don’t see it all, our scope is limited even within space-time. And from what we can observe, nothing indicates a center. For all we know, there isn’t one, just like you can’t paint a dot on the surface of a ball and call it the center of the surface, every point on the ball’s surface has equal claim to that. In that situation relativity is all that there is. Unless there’s a massive breakthrough, it’s looking like the laws of physics won’t permit us to know if a center exists, let alone find it.
