Scientific paper
Previous investigations of group-theory cosmology are reviewed, particularly with respect to effects of increasing gravity on solar evolution. Calculations are performed which show that if an extensive molecular hydrogen atmosphere was retained when earth formed or if there was appreciable outgassing of hydrogen, a sufficiently strong greenhouse effect could be provided which would compensate for the low solar luminosity predicted by group-theory cosmology. The results indicate that the average surface temperature of earth would have been well above the freezing point of water as long as the sun was bright enough 3 or 4 billion years ago to give an effective temperature of at least 90 K for an atmosphereless earth. It is concluded that it is premature to rule out group-theory cosmology just because it predicts a low solar luminosity several billion years ago.
