SUMMARY
The discussion centers on the analysis of spectral data from two distant galaxies, represented by a white spectrum and a red spectrum. Participants confirm that the left spectrum (white) and the right spectrum (red) correspond to galaxies at different distances. The velocity of the red-shifted spectrum can be determined by comparing it to the left spectrum, as the shape of the spectra remains consistent, allowing for measurement of wavelength shifts in peaks or absorption lines.
