An Open Inflationary Model for Dimensional Reduction and its Effects on the Observable Parameters of the Universe
Koray Karaca, Selcuk Bayin
Assuming that higher dimensions existed in the early stages of the universe where the evolution was inflationary, we construct an open, singularity-free, spatially homogeneous and…
Missing Mass, Dark Energy and the Acceleration of the Universe. Is Acceleration Here to Stay?
Selcuk Bayin
In this paper we present an alternative explanation to the acceleration of the universe and the dark energy problems in terms of the Friedmann Thermodynamics. This model has the ca…
Inflation in Flat Universe
Koray Karaca, Selcuk Bayin
We started the evolution of a flat universe from a nonsingular state called prematter which is governed by an inflationary equation of state where represents…
Missing Mass and the Acceleration of the Universe. Is Quintessence the only Explanation?
Selcuk Bayin
Detailed observations of the temperature fluctuations in the microwave background radiation indicate that we live in an open universe. From the size of these fluctuations it is con…
An Open Singularity-Free Cosmological Model with Inflation
Koray Karaca, Selcuk Bayin
In the light of recent observations which point to an open universe , we construct an open singularity-free cosmological model by reconsidering a model originally constr…
A Singularity-Free Cosmological Model with a Conformally Coupled Scalar Field
S. S. Bayin, F. I. Cooperstock, V. Faraoni
We explore the possibility of describing our universe with a singularity--free, closed, spatially homogeneous and isotropic cosmological model, using only general relativity and a…
