  The term 'quc' is shorthand here for a cosmological -- not a physical --
'quantum-universe constituent'. Although self-adjoint Hilbert-space
angular-momentum and momentum operators unitarily generate quc rotations and
spatial displacements, no single-quc is a physical 'thing'. Photons, 3
generations of fermions, plus massive vector and scalar bosons -- all
physicist-deemed 'elementary' -- as well as dark matter, galaxies and black
holes, within an evolving universe are, we propose, each a temporary 'quc
family' that aggregates 8 Noether-conserved quc attributes. No 'thing' is
elementary. Here proposed is a thing-devoid 'von-Neumann big bang' -- that
established a huge but finite and permanent set of speed-c chiral qucs, with
'masses' M h /2{\tau}c 2 , where M = 1, 2,... M max and {\tau} is 'universe
age'. ('Quc-mass', although not physically-meaningful, has the same
dimensionality as any thing 's 'mass'.) Quc-aggregate (thing) creations and
disappearances -- i.e., 'evolution' -- are symmetry-governed by an 8-parameter
'centered-Lorentz' (CL) Lie group. CL's 6-parameter SL (2, c) Riemann-geometric
'exterior' of quc rotations and hyperbolic spatial displacements, has a
conserved algebra of quc angular-momentum together with quc momentum times
{\tau}. A 2-parameter non-geometric CL-central algebra comprises a pair of
discrete coupled and conserved quc attributes -- electric charge and
'chirality'. Chirality, without any physics counterpart, renders CL a
supersymmetry and provides our present universe with nuclear forces -- 'strong
interactions'.
