We are 3D creatures stuck in a universe with at least four dimensions, so we cannot see the center of our universe. In fact, there’s no reason why there has to even be a center anywhere.

But if the universe consists of all regions, there can't be an edge. This means the universe might be infinitely big, and it's impossible to point to the center of an infinite space.

Earth still has a center of course, but no one lives there. The nature of the universe is so different from the everyday objects we experience that we lack better metaphors to compare it to.

So in asking about the center of the universe, we’re confronting the limits of our intuition. The answer we find – everything, expanding everywhere, all at once – is a glimpse of just how ...

In our universe, there is no such “interior ” to anchor a center. Just as there is no center on the surface of a balloon, there is no central point in the universe.

As the universe expands, it feels like it must be spreading out from some initial point. But a physicist explains why that’s not how it works. Hint: space-time is involved.
