Singularity Free (homogeneous Isotropic) Universe in Graviton-dilaton Models
We present a class of graviton-dilaton models in which a homogeneous isotropic universe, such as our observed one, evolves with no singularity at any time. Such models may stand on their own as interesting models for singularity free cosmology, and may be studied further accordingly. They may also arise from string theory. We discuss critically a few such possibilities. PACS numbers: 98.80.Hw, ...
متن کاملLHC Create a Rainbow Universe
This paper explains the Accelerating Universe, the Special and General Relativity from the observed effects of the accelerating electrons, causing naturally the experienced changes of the electric field potential along the moving electric charges. The accelerating electrons explain not only the Maxwell Equations and the Special Relativity, but the Heisenberg Uncertainty Relation, the wave parti...
متن کاملSingularity-free Cosmological Model
We " explain " , using a Classical approach, how the Universe was created out of " nothing " ,i.e., with no input of initial energy nor mass. The inflationary phase, with exponential expansion, is accounted for, automatically , by our equation of state for the very early Universe. This is a Universe with no-initial infinite singularity of energy density.
متن کاملSingularity-free space-time.
We show that the solution published in the paper by Senovilla [Phys. Rev. Lett. 64, 2219 (1990)] is geodesically complete and singularity-free. We also prove that the solution satisfies the stronger energy and causality conditions, such as global hyperbolicity, the strong energy condition, causal symmetry, and causal stability. A detailed discussion about which assumptions in the singularity th...
متن کاملSingularity-Free Cylindrical Cosmological Model
A cylindrically symmetric perfect fluid spacetime with no curvature singularity is shown. The equation of state for the perfect fluid is that of a stiff fluid. The metric is diagonal and non-separable in comoving coordinates for the fluid. It is proven that the spacetime is geodesically complete and globally hyperbolic. PACS 04.20.Jb, 98.80.Hw
