Abstract
Since the James Webspace Telescope, JWST came into operation during the first half of the year 2022, cosmological times and distances have been reported, that reach more than 13 billion years and light years. These cosmological data are of a much higher order of magnitude than those handled in traditional astronomy. When analyzing the information published by Naidu, R. P. et al. and other authors, about the Galaxy Glass-z13, GZ, recently discovered by the JWSP, where a redshift, z = 13.1, of the captured signals was measured; it is concluded that GZ is being seen in the form and position in which it was 13,500 million years ago. During this time the light traveled a distance, Dv, equivalent to 13.5 billion light years, for now, been detected in the Milky Way, MW. Next, it is explained what this data means and how it is possible to calculate: 1). The distance, Da, the two galaxies (MW and GZ) are now, 2). The distance, Do, at which the said galaxies were located 13,500 million years ago, 3). The distance, Dm, that each of the galaxies moved, towards opposite directions, 4). The scale factor, a(t), and the relation of the commoving distance, to the proper distance, and 5). The comparison of the above-mentioned cosmological distances, with other local astronomical distances such as the distance between the MW and the Andromeda galaxy and also the distance between the Earth and a planet, but that of the closest star to the Sun, the planet Proxima Centauri b, described by Davis, N. K. S. These comparisons are intended to get a better idea of the orders of magnitude that cosmological distances and astronomical distances mean.
