Bessel 21 (Detail) by Eric J. Heller. A superposition of 21 plane waves, traveling in 21 evenly spaced directions around the compass, results in an approximation to a Bessel function near the center of the "comet".

Let's put two and two together.

If space is the totality of spatial relations existing between the "ultimate constituents of matter," then matter is the corresponding totality of relata (plural of relatum = one of two related things).

We thus arrive at a unified conception of matter and space that is elegant and economical by any standard.

If we add to it that the number of ultimate constituents is one, we obtain what may be the most economical creation saga ever told (and all we have done is unpack some of the implications of the quantum mechanical probability assignments):
