  1. Frequency-based redshift for cosmological observation and Hubble diagram from the 4-D spherical model in comparison with observed supernovae DICE2016, Sep. 12 - 16, Castiglioncello (Italy) Shigeto Nagao, Ph.D. (Osaka, Japan) Summary  According to the formerly reported 4-D spherical model of the universe, factors on Hubble diagrams are discussed.  The observed redshift is not the prolongation of wavelength from that of the source at the emission but from the wavelength of spectrum of the present atom, equal to the redshift based on the shift of frequency from the time of emission.  The K-correction corresponds to conversion of the light propagated distance (luminosity distance) to the proper distance at present (present distance).   Comparison of the graph of the present distance times versus the frequency-based redshift 1 z with the reported Hubble diagrams from the Supernova Cosmology Project, which were time-dilated  by and K-corrected, showed an excellent fit for the Present Time (radius of 4-D sphere) being 1 z 0.7 of its maximum.

  2. 4-D Spherical Model of the Universe  The space energy spreads with expansion in a 3-D surface of a 4-D sphere. A vibration of the intrinsic space energy in the 3-D space vests additional energy, which is light or a quantum particle. Radius x of the 4-D sphere is our “Observed Time” ( Time or T ), which we feel passing commonly for all of us. x : Radius vector of 4D sphere      θ x ( x , ) ( x , , , ) (4D spherical coordinate) 1 2 3 r : 3D space vector corresponding to θ x Phase Transition Space expansion r        r ( r , , ) ( x , , ) 1 2 1 2 x by 4D cylindrical coordinate:        x ( x , r , , ) ( x , x , , ) 1 2 1 2 < Definition of terms related to Time > x (Radius of universe): Radius of the 4D sphere of universe, equal to the Observed Time ( T ) CU (Cosmic Unit): Unit of x and T , being one at its maximum when the space expansion stops.
