Aspects of Quantum Cosmology

Quantum mechanics may be formulated as Sensible Quantum Mechanics (SQM) so that it contains nothing probabilistic, except, in a certain frequency sense, conscious perceptions. Sets of these perceptions can be deterministically realized with measures given by expectation values of positive-operatorvalued awareness operators in a quantum state of the universe which never jumps or collapses. Ratio...

Three Aspects of Typicality in Multiverse Cosmology

Extracting predictions from cosmological theories that describe a multiverse, for what we are likely to observe in our domain, is crucial to establishing the validity of these theories. One way to extract such predictions is from theorygenerated probability distributions that allow for selection effects—generally expressed in terms of assumptions about anthropic conditionalization and how typic...

Some Aspects of Pre Big Bang Cosmology

This is a summary of a course given at the Fourth Mexican School on Gravitation and Mathematical Physics on some aspects of PBB cosmology. After introductory remarks the lectures concentrate on some amusing consequences derived from the symmetries of the string theory with respect to such classical concepts as isotropy and homogeneity. The extra dimensions and the symmetries of the M theory are...

Global Structure of a Multi-Fluid Cosmology

Fluid cosmologies are consistent with the generally accepted observational evidence during intermediate and late times, and they need not have singular behavior in primordial times. A general form for fluid cosmology consistent with Einstein’s equation is demonstrated, and a dynamic metric that incorporates fluid scale is developed. The large scale causal structure of a multi-fluid cosmology ex...

Self-Gravitating Global Monopole and Nonsingular Cosmology

We review some recent results concerning the properties of a spherically symmetric global monopole in (D = d+2)-dimensional general relativity. Some common features of monopole solutions are found independently of the choice of the symmetry-breaking potential. Thus, the solutions show six types of qualitative behavior and can contain at most one simple horizon. For the standard Mexican hat (Hig...
