Scientific paper

The origin of life is approached from the standpoint of cosmic history, i.e., beginning with the Big Bang, through the contraction of galactic nebulae into individual suns, and finally planetary formation by accretion and mass transfer from the central star of the proto-planetary nebula. Observations of a star, MWC 349, in the shape of a brightly glowing disk in the constellation of Cygnus are used for empirical support of the nebular hypothesis. It is noted that the disk loses approximately 1% of its brightness per month due to mass transfer into the central star. Attention is given to cosmic abundances of light elements, e.g., H, He, N, O, C, Ne, Si, etc., and to the probable composition of the earth, based on the materials available in the early solar system. It is pointed out that according to the nebular hypothesis, and in light of recent observations concerning the frequency of binary stars and perturbations in the motions of nearby stars, the planetary formation is probably common throughout the universe, and possibly, also, intelligent life.
