A Revival of the De Sitter Universe

  • Leopold Halpern

Abstract

The large number hypothesis (LNH) was proposed by Dirac1,2 in 1937; it is related to the assumptions made in Eddington’s ‘Fundamental Theory’, modified, however, by the variation of the dimensionless large numbers with time. The original version was later modified to a theory with matter creation in the expanding universe3. For a while this theory seemed to be in better agreement with empirical data; it was given up when it was shown to yield results conflicting with our present knowledge on the Moon’s surface. The present version4 does not assume matter creation; it is closer related to the original version which can again fit empirical results, because of the change of our estimate of the Hubble parameter.
