Comment on “Singularity-free Cosmological Solutions with Non-rotating Perfect Fluids”
A conjecture stated by Raychaudhuri which claims that the only physical perfect fluid non-rotating non-singular cosmological models are comprised in the Ruiz-Senovilla and Fernández-Jambrina families is shown to be incorrect. An explicit counterexample is provided and the failure of the argument leading to the result is explicitly pointed out. Since the publication of the first non-singular cos...
متن کاملSingularity-free Cosmological Solutions in String Theories
Singularity-free cosmological solutions may be obtained from the string action at tree level if the dimension of the space-time is greater than 10 and if brane configurations are taken into account. The behaviour of the dilaton field in this case is also regular. Asymptotically a radiative phase is attained indicating a smooth transition to the standard cosmological model.

متن کاملNew nondiagonal singularity-free cosmological perfect-fluid solution.
We present a new non-diagonal G2 inhomogeneous perfect-fluid solution with barotropic equation of state p = ρ and positive density everywhere. It satisfies the global hyperbolicity condition and has no curvature singularity anywhere. This solution is very simple in form and has two arbitrary constants. PACS Numbers: 04.20-Jb; 04.20-Cv; 98.80-Dr. The study of exact inhomogeneous cosmological mod...
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 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
