It is considered that quasars evolve into normal galaxies by means of expansion of matter. The order of magnitude of the expansion velocity can be estimated. The Doppler shift caused by such expansion explains the supposed variation of the fine structure constant. This variation has been based on observations of absorption lines of gas clouds seen against background quasars. These ideas maintain the constancy of the fine structure constant.
