““As long as two fields that describe one and the same space are identified, the field and the space can be used synonomously. There is no such thing, then, as a quantity called space that can be defined in terms of a set of coordinates and is independent of the field consisting of numbers that tell the distances between any two points with different coordinates. We might say that the four-dimensional field contains all information on the spatial character of our reality. In this sense, there is no empty space: There is no space without a field.””
