Cosmogony of Generic Structures
The problem of formation of generic structures in the Universe is addressed, whereby rst the kinematics of inertial continua for coherent initial data is considered. The generalization to self{gravitating continua is outlined focused on the classiication problem of singularities and metamorphoses arising in the density eld. Self{gravity gives rise to an internal hierarchy of structures, and, dr...
متن کاملCosmic Chemistry: Cosmogony
Big Bang, quarks, dark matter, general relativity, red-shift, non-Euclidean geometry, worm holes—all words that are mysterious in their details, but often translated into the vernacular with relative ease by journalists and science writers. These words form part of the core of the science of cosmology, a science in which the questions usually are easy to state, but equally difficult to answer. ...
متن کاملCosmology and Cosmogony in a Cyclic Universe
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 and J. V. Narlikar forty years ago. It is shown that the creation processes which takes place ...
متن کاملThe Cosmogony of Super-Massive Black Holes
• The luminosities of the quasars with the largest redshifts indicate that central BH masses of > 10 M⊙ were already present when the Universe was less than 10 years old (Barth et al. 2003). These masses are lower limits as they are based on the assumption that the BHs accrete at their Eddington limit. There is no indication that the (majority of the) sample of highest-redshift-quasar luminosit...
