WebRed-shift is observed when the spectral lines from the distant galaxy move closer to the red end of the spectrum This is because light waves are stretched by the expansion of the universe so the wavelength increases (or frequency decreases) This indicates that the galaxies are moving away from us WebIn 1929, Edwin Hubble announced that almost all galaxies appeared to be moving away from us. In fact, he found that the universe was expanding - with all of the galaxies moving away from each other. This phenomenon …
How does a redshift give evidence to the Big Bang Theory?
WebIt was during the 1920’s that Edwin Hubble provided the first evidence that we live in an expanding Universe. Hubble discovered that there is a simple relationship between the distance to a remote galaxy and the redshift in the spectral lines from that galaxy. This redshift is know as the cosmological redshift. Web1. Redshift of Galaxies The light we observe from galaxies has been stretched by the time it reaches us. It looks redder than it should. This redshift is the result of galaxies moving away from us. Observations … stephen d young
