That we cannot give a justification – or sufficient reasons – for our guesses does not mean that we may not have guessed the truth.

If studied in detail, the mass flows from the stars appear to be variable. “Mere inspection of solar wind data reveals large variations on a time scale of several days” (Hundhausen, 1972). Also, “it is obvious that mass loss from hot stars is not a stationary phenomenon but that variations on short timescale occur” (de Jager et. al., 1979). And a cool supergiant has “a photosphere fluctuating in both brightness and radial velocity, (and) an expanding chromosphere … uncoupled from motions in the photosphere” (Goldberg, 1979).
