The Traditional Approach: Turbulence and Gravitational Instability,uch initial clouds, their estimates usually being based on ‘reasonable physical arguments’, but such estimates are always in the range 10. g cm. to 10.g cm. (the lower limit is the observed mean density within a cluster of galaxies, and the upper the observed mean density within our own galaxy).

https://doi.org/10.1007/978-3-540-89465-0Although Ambartsumian considers a fragmentation process, his approach is completely different from that of the ‘traditional’ hypotheses discussed in previous chapters. The basis of the theory is the existence and form of the observed clustering of astronomical systems, ranging from binary stars to clusters of galaxies.

,Winter Wheat Research in Türkiye,Most of the basic results of relativistic cosmology also emerge from an equivalent treatment using Newtonian theory, although there is one stratagem that has to be used right at the beginning, because Newtonian gravitational theory cannot cope with infinities. But once used, matters become fairly simple for the Newtonian cosmologist.
