    "abstract": "Classical determinations of galaxy distances and galaxy recessional\nvelocities have been generated from luminosity and emission spectrometric data.\nThe analyses of these galactic spectrometric electromagnetic frequency shifts\nhave resulted in the Hubble law and are understood as a Doppler effect stemming\nfrom an expansion of space. In the present work, a galaxy-core expansion model\nwith a time evolving matter and radiation distribution is put forth, leading to\na supplementary treatment of the optical redshift measurements. Einstein\u0027s\ngravitational equations are assumed to apply within a galaxy-core spatial\ndomain and, with utilization of a generalized Robertson-Walker-Schwarzschild\nmetric, are used in order to calculate the evolutionary expansion\ncharacteristics. The galaxy-core model is described as a flat metric, matter\nplus radiation, sigma = 1/3, energy distribution. It predicts an early time\ndensity fluctuation collapse, understood to be the formation of a galaxy hole,\nand provides an interpretational basis for the experimental data.",
