Web24. feb 2024 · redshift, displacement of the spectrum of an astronomical object toward longer (red) wavelengths. It is attributed to the Doppler effect, a change in wavelength that results when a given source of waves (e.g., light or radio waves) and an observer are in motion with respect to each other. The American astronomer Edwin Powell Hubble … WebThe near galaxy is moving away from us ( from the shift in the lines) at 1% the speed of light. If it were scatters, the lines would be blurred, not recognizable, not clear as we measure them. The most economical interpretation of the distances ( measured with the cosmic distance ladder) and the redshifts is that everything is receding from us.
