    a natural and consistent explanation of

    (i) dark energy,

    (ii) the coincidence problem (here conceptually,not quantitatively),

    (iii) positive initial curvature,

    (iv) the small matter density cosmological parameterfound in local probes of the matter density,

    (v) the large angular diameter distance tothe CMB consistent with JLA supernova sample parameter constraints,

    and (vi) the local expansion rate measurements (removal of the ‘Hubble tension’).

    We believe that this model architecture needs convincing arguments to be rejected as a physically viable show-case, on the basis of which the model ingredients can be improved in order to build a physical cosmology in the future.
