Lorentzian Gravity and Cosmology

چکیده
If a material vacuum exists, with the properties of a superfluid through which already recognized material moves, then it is capable of acting as a universal reference frame and as an intermediary for the production of particle pairs throughout the universe, which as they cool and recombine, become the source of both high-and low-temperature cosmic background radiation, as observed. Moreover, if there is a steady state overall in the universe and the depleted material vacuum is replenished within temporary galactic nuclei of hyperinflated mass, as predicted by certain classes of gravitational theory (Dicke 1961, Atkinson 1962), then the standard interpretation of cosmological redshifts and the reality of the big bang may be called in question. Thus the existence of substantial dark matter in the universe, due to mass inflation in recurrent galactic nuclei, along with large scale streaming over the dimensions of superclusters and voids, not only revives the possibility of a considerable gravitational component (cf. Schmidt 1975) in the redshifts of quasars, which are then nearby, but raises again the * Presented at the meeting on Physical Interpretations of Relativity Theory. possibility, foreseen with the static universe model of de Sitter (1917), that the cosmological redshift itself is purely gravitational in origin. Under these circumstances, the Lorentzian explanation of covariance is no longer implausible and we may recover the nineteenth-century assumption that the various observed fields in nature are manifestations of active physical states of the material vacuum associated with corresponding states of recognized matter. Theories that explain gravitational fields within this framework (e.g., relativistic: Atkinson 1962; non-relativistic: Dicke 1961) predict the existence and recurring production of hyperinflated matter, and are relevant to our understanding of the strong nuclear force (Sinha et al. 1976a, b) and of the fundamental behavior of massive astronomical bodies in advanced states of evolution, e.g., pulsars, quasars (Clube 1983). Such behavior (i.e. the formation of hyperinflated mass) is reflected, for example, in the widespread violent relaxation of galaxies, not least our own, and leads to an understanding of spiral structure different from that generally accepted at present (e.g., Lin & Shu 1964), but first mooted many years ago by Jeans (1928) and Milne (1948).

Pauli (or Einstein) frame is used to study the Brans-Dicke gravity theory, minimally coupled with dilatonic Brans-Dicke scalar field, whose solutions involve degenerate metrics. Some of these solutions exhibit transitions from an Euclidean domain to a Lorentzian space-time corresponding to a spatially flat Robertson-Walker cosmology.
متن کاملA Lorentzian Lipschitz, Gromov-Hausdorff notion of distance
This paper is the first of three in which I study the moduli space of isometry classes of (compact) globally hyperbolic spacetimes (with boundary). I introduce a notion of Gromov-Hausdorff distance which makes this moduli space into a metric space. Further properties of this metric space are studied in the next papers. The importance of the work can be situated in fields such as cosmology, quan...

متن کاملCosmology of the Lifshitz universe
We study the ultraviolet complete non-relativistic theory recently proposed by Hořava. After introducing a Lifshitz scalar for a general background, we analyze the cosmology of the model in Lorentzian and Euclidean signature. Vacuum solutions are found and it is argued the existence of non-singular bouncing profiles. We find a general qualitative agreement with both the picture of Causal Dynami...
متن کاملAlgorithmic Complexity in Cosmology and Quantum Gravity
In this article we use the idea of algorithmic complexity (AC) to study various cosmological scenarios, and as a means of quantizing the gravitational interaction. We look at 5D and 7D cosmological models where the Universe begins as a higher dimensional Planck size spacetime which fluctuates between Euclidean and Lorentzian signatures. These fluctuations are governed by the AC of the two diffe...
متن کاملA Hexagon Model for 3D Lorentzian Quantum Cosmology
We formulate a dynamically triangulated model of three-dimensional Lorentzian quantum gravity whose spatial sections are flat two-tori. It is shown that the combinatorics involved in evaluating the one-step propagator (the transfer matrix) is that of a set of vicious walkers on a two-dimensional lattice with periodic boundary conditions and that the entropy of the model scales exponentially wit...
