  • Summary

    The chapter briefly discusses an alternative explanation of the CMB origin in the semipopular plasma cosmology of O. Klein, later advocated by others. The approach took the still mysterious observed matter–antimatter asymmetry as its starting point, arguing in favor of symmetry with slow annihilation that provides (in principle) the energy contained in the CMB. Later versions added a challenge to the dark matter hypothesis and its solution by pointing to the problem of equilibrated parts of the expanding universe. Although developed in some detail, this sort of explanation eventually had to draw on older ideas (e.g., tired-light hypothesis) in the face of the COBE mission results.
