Abstract
MILNE1 has recently suggested that Planck's ‘constant’ h may vary with time, the variation being significant for the interpretation of the spectra of distant galaxies. According to Milne's discussion, h varies linearly with t, the present value of the latter being of the order of 2 × 109 years. This possibility has the particular merit of reconciling the observed red-shifts with the principle of conservation of energy. It is the object of the present letter to point out some other significant consequences of Milne's law.
