Abstract:An unorthodox cosmology is based on a notion of ldquostandpoint,rdquo distinguishing past from future, realized through Hilbert-space representation of the complex conformai group for 3+1spacetime and associated coherent states. Physical (approximate) symmetry attaches to eight-parameter complex Poincaré displacements, interpretable as growth of standpoint age (one parameter), boost of matter energy-momentum in standpoint rest frame (three parameters) and displacement of matter location in a compact U(1)otimesO(4)/O(3) spacetime attached to standpoint (four parameters). An ldquoinitialrdquo condition (at ldquobig bangrdquo) is characterized by a huge dimensionless parameter agr that breaks dilation invariance. Four major length scales are recognized, called ldquoPlanck,rdquo ldquoparticle,rdquo ldquolab,rdquo and ldquoHubble,rdquo with separations controlled by agr; all physical concepts, including spacetime, depend on wideness of scale separation.
