in Wolfram’s universe?

We know what it means when we say that our universe is three-dimensional: it means that we can move in three orthogonal directions: left-right; up-down; forwards-backwards.

But what would it mean to say that a universe is 2½-dimensional?

Or 3.37-dimensional?

Or 9-dimensional?

When I measured the dimensionality one of Wolfram’s graphs, I found it to be *at least* 3.37-dimensional.

If Stephen Wolfram is right, then our universe might *not* be uniformly three-dimensional.

So maybe dimensionality isn’t quite what we think it is.

What, exactly, *are* dimensions?
