Special Issue Information

Dear Colleagues,

Various fields of study in theoretical particle physics and quantum gravity are having profound impacts on cosmology. Our understanding of the universe has been and continues to be deeply altered by advancements in these fields. The present “special issue” is to focus on the current cosmological implications of fields within these two realms. We would like to call for papers disseminating and discussing implications for cosmology resulting from areas of particle physics and quantum gravity, including, but are not limited to:

  • string/M-/F-theory
  • brane interactions
  • loop quantum gravity
  • Horava-Lifshitz gravity
  • trans-Planckian physics
  • causal dynamical triangulation
  • causal sets
  • non-commutative geometries

Review papers are also welcome.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. Papers will be published continuously (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are refereed through a peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Galaxies is an international peer-reviewed Open Access quarterly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. For the first couple of issues the Article Processing Charge (APC) will be waived for well-prepared manuscripts. English correction and/or formatting fees of 250 CHF (Swiss Francs) will be charged in certain cases for those articles accepted for publication that require extensive additional formatting and/or English corrections.

Title: Holographic Cosmology and Inflationary Observables
Authors: Thomas Banks and W. Fischler
Affiliation: Santa Cruz Institute for Particle Physics, University of California Santa Cruz, 1156 High Street, Santa Cruz, CA 95064, USA; E-Mail: banks@scipp.ucsc.edu
Abstract: Holographic Cosmology is part of a general theory of quantum gravity called Holographic Space Time, which views a space-time as an infinite number of quantum systems, each associated with evolution along a time-like trajectory, with consistency relations for shared information. It provides a completely non-singular description of the Big Bang, and derives homogeneity, isotropy and flatness as generic properties of the very early universe. The early equation of state is pressure equals energy density. A new version of the theory incorporates inflation and makes predictions for the fluctuation spectrum that agree with current data. The predictions differ from those of most inflation models. In particular, the tilt of the tensor spectrum vanishes and the tensor 3 point function should have all 3 functional forms compatible with SO(1,4) invariance. As a byproduct of this analysis we showed that current cosmological data could be explained by any model compatible with approximate SO(1,4) invariance and general properties of cosmological perturbation theory.

Title: A Dumbbell Universe with an Accelerated Cosmic Expansion and a Total-Unified Model
Jong-Ping Hsu and Kazuo Ota Cottrell
A total-unified model with gauge groups (T4)Y Mgravity × (SU3)color × (SU2 × U1) × U1b in flat space-time implies that all interactions should preserve conservation laws of baryon number, electric charge, etc. The baryonic U1b gauge transformations are assumed to involve a vector gauge function, so that one has gauge invariant fourth-order equation for baryonic gauge field. This new gauge field produces a very small constant repulsive force among baryon galaxies (or among anti-baryon galaxies), where the force overcomes the gravitational force at very large distances and leads to a cosmic constant-acceleration expansion. Based on particle physics, we discuss a simple rotating dumbbell universe with equal amounts of matter and anti-matter, which may be pictured as two gigantic rotating clusters of galaxies. Within each gigantic cluster, there is a cosmic constant- acceleration expansion. However, the matter-antimatter of the dumbbell universe as a whole is not expanding and is permanently confined by the long-range constant attractive forces between the two gigantic clusters.
