Cosmic Dispersal of Matter

The near-equality of cosmic and solar abundancies of the chemical elements points at either a single synthesis event, starting from elementary matter, or a common mechanism of nucleogenesis, wherever it happens. The first possibility is the one originally preferred in big-bang cosmology, but later abandoned as there was considered not to be enough time available for this process in the early universe. [Pg.253]

but significant, differences between solar, meteoric and cosmic-ray abundances imply that environmental effects, which vary between different space-time regions, are also at play in nucleogenesis. [Pg.253]

As the plasma moves through the centre of maximum curvature it is forced through the vacumn interface into a space-time domain of inverted chirahty and decreasing pressme. New matter (antimatter) emerges beyond the interface as an equilibrimn mixture of cosmic rays, in a soup of a-particles, as it is squirted out from the black hole into free space. Some of the newly formed nuchdes decay radioactively on moving into regions of lower curvatme and a set of nuclides, characteristic of local cmvatme, smvives. In the solar system the set consists of the 264 stable isotopes of 81 elements described before. The closed periodic sytem of nuclides and anti-nuclides, related by inversion, is consistent with the proposed mode of cosmic circulation of mass. [Pg.253]

This scenario explains the periodic abimdance of atomic nuchdes and the origin of cosmic rays, which consist of the bare nuclei of all natmal elements moving at relativistic speeds through the galaxy. By comparison, the standard model of stellar nucleosynthesis cannot explain the matching abundances of elements in the solar system and in cosmic rays. [Pg.253]

A notable feature of the spiral structures is the lack of a heavy core as seen in spiral galaxies, such as M51, shown in Plate 5.1. A reasonable explanation of this and of the uniform alignment and chirality of the spirals is that they originate in turbulent flow firom a central point, and therefore seen oriented in the same radial projection. In hydrodynamics such structures are known as vortices or eddies. Each of the eddies generated by the turbulent expansion is the potential nucleus of a new galaxy. [Pg.256]
