Abstract: A considering of a very slow shift in the nucleon rest mass is proposed in order to avoid the assumption of acceleration in the expansion of the universe. A recent yearly change in the order of magnitude of 5*10-11 is sufficient for an alternative approach, which interprets the discrepancy between the low intensity of far-distance supernovae Ia and their red-shift by a reduction of supernovae energy. Such a reduction of intensity could be explained by a lowered critical mass of the white dwarf due to higher nucleon masses and lower required particle numbers in the critical state.Abstract: A considering of a very slow shift in the nucleon rest mass is proposed in order to avoid the assumption of acceleration in the expansion of the universe.
