Prespacetime Journal Volume 4 Issue 5: Various Aspects of Gravitation & Cosmology

Prespacetime Journal ("PSTJ," http://www.prespacetime.com) is a publication in which physicists, mathematicians and other learned scholars publish their research results and express their views on the origin, nature and mechanism of spacetime and its possible connection to a prespacetime. It is also a journal where all learned scholars can present their models and experimental results on elemental particles, fundamental forces including gravity and related topics. This is PSTJ Volume 4 Issue 5 first published in May 2013. It is entitled "Various Aspects of Gravitation & Cosmology" and contains following articles: (1) Bounds upon Graviton Mass: Post-Newtonian Corrections to Gravitational Potential Fields; (2) The Voids between Galaxy Clusters and the Chirality of Spiral Galaxies; (3) On the Theory of Gravitation Part 5: Interrelation of Mass and Gravitation according to NTEP and SM; (4) Bianchi Type-I Bulk Viscous Cosmological Models in Lyra Geometry; (5) C-field Cosmological Model for Dust Distribution with Varying Lambda in FRW Space-time; (6) Kaluza-Klein Type Dissipative Future Universe without Big Rip; (7) Five-dimensional Dust Static Spherically Symmetric Non-vacuum Solution in f(R) Theory of Gravity; (8) Perfect Fluid Cosmological Models in GR and f(R,T) Gravity; (9) Non-static Plane Symmetric Zeldovich Universe in a Modified Theory of Gravity; and (10) Why I Still Like String Theory.
