To determine the shape of the universe, we need to study how galaxies are distributed across the celestial dome; in other words, we need density measurements of numbers of galaxies in the universe. These measurements have been made, for which astronomy uses the redshift of spectral lines in the light spectrum of galaxies. The light from very distant galaxies is shifted so far into the red that it arrives here even as infrared. The latter is the specialty of the James Webb space telescope. The Hubble space telescope already showed that the universe is round. We predict that the JWST will once again confirm this through measurements of the most distant galaxies.
