How do we know space is three-dimensional, or space-time four-dimensional? Is there a simple experiment one can do to determine the dimensionality of space or of space-time? (I'm thinking of dimensions of ordinary (nearly) Euclidean space observable by ordinary means, not such exotic things as the very highly curved extra dimensions that I understand are postulated by some theories.)
