Observations and nonstandard FRW models

摘要: The observational predictions of various nonstandard cosmological models which have an FRW metric as their space-time geometry are investigated. general numerical the found to be in accord with actual observations; particular, they predict a current relative velocity Galaxy respect CMB consistent measurements dipole anisotropy temperature distribution, and also quadrupole anisotropy, magnitude is well below upper limits obtained from observations. distance versus redshift relationship calculated typical model same corresponding standard model. critical density problem addressed, behavior expansion thermodynamics considered, predicted helium abundance estimates.
