“One of the most striking results of modern investigation has been the way in which several different and quite independent lines of evidence indicate that a very great event occurred about two thousand million years ago. The radio-active evidence for the age of meteorites; and the estimated time for the tidal evolution of the Moon's orbit (though this is much rougher), all agree in their testimony, and, what is far more important, the red-shift in the nebulae indicates that this date is fundamental, not merely in the history of our system, but in that of the material universe as a whole.” AgeScienceTimeUniverseSpaceHistoryEvolutionMoonEvidenceAstronomyInvestigationTestimonyOrbitEventStrikingRadioactiveMeteoritesNebulaeRedshift Author:Henry Norris Russell
