Abstract
In this paper we discuss the properties of the quasi-steady state
cosmological model (QSSC) developed in 1993 in its role as a cyclic model
of the universe driven by a negative energy scalar field. We discuss the
origin of such a scalar field in the primary creation process first described
by F. Hoyle & J. V. Narlikar forty years ago. It is shown that the creation
processes which take place in the nuclei of galaxies are closely linked to
the high energy and explosive phenomena, which are commonly observed
in galaxies at all redshifts.
The cyclic nature of the universe provides a natural link between the
places of origin of the microwave background radiation (arising in hydrogen
burning in stars), and the origin of the lightest nuclei (H, D, He³ and
He⁴). It also allows us to relate the large scale cyclic properties of the universe
to events taking place in the nuclei of galaxies. Observational evidence
shows that ejection of matter and energy from these centers in the
form of compact objects, gas and relativistic particles is responsible for the
population of quasi-stellar objects (QSOs) and gamma-ray burst sources
in the universe.
In the later parts of the paper we briefly discuss the major unsolved
problems of this integrated cosmological and cosmogonical scheme – the
understanding of the origin of the intrinsic redshifts, and the periodicities
in the redshift distribution of the QSOs.
