Based on concepts drawn from the ekpyrotic scenario and M theory, we elaborate our recent proposal of a cyclic model of the universe. In this model, the universe undergoes an endless sequence of cosmic epochs which begin with the universe expanding from a ``big bang'' and end with the universe contracting to a ``big crunch.'' Matching from ``big crunch'' to ``big bang'' is performed according to the prescription recently proposed with Khoury, Ovrut and Seiberg. The expansion part of the cycle…

The Genesis of the Big-Bang and Inflation

The standard model of cosmology posits that some time in the remote past, labelled as t=0, a Big-Bang occurred. However, it does not tell what caused the Big-Bang and subsequently the Inflation. In

Creation of particles in a cyclic universe driven by loop quantum cosmology

We consider an isotropic and homogeneous universe in loop quantum cosmology (LQC). We assume that the matter content of the universe is dominated by dust matter in early time and a phantom matter at

From the Early Universe to the Modern Universe

The problem of the cosmological constant is solved and the crisis of physics connected with this constant is overcome, and the model of a slowly swelling Universe in the result of the multiple reproductions ofcosmological cycles arises naturally.

Oscillating Theory of The Universe

We propose here a new theory of the cosmic evolution of the universe, giving its name as the "oscillating theory of the universe". In this theory we have an endless universe having different epochs

A Comparison of two Cosmological Models: Inationary Cosmology and the Cyclic Universe

To explain current observations the early universe must have been incredibly at and homogeneous. Tiny density uctuations must have been present to seed large scale structure. Any viable model of the

M theory model of a big crunch/big bang transition

We consider a picture in which the transition from a big crunch to a big bang corresponds to the collision of two empty orbifold planes approaching each other at a constant nonrelativistic speed in a

J un 2 00 8 Ekpyrotic and Cyclic Cosmology

Ekpyrotic and cyclic cosmologies provide theories of the very early and of the very late universe. In these models, the big bang is described as a collision of branes and thus the big bang is not the

Entropy of contracting universe in cyclic cosmology

Following up a recent proposal1 for a cyclic model based on phantom dark energy, we examine the content of the contracting universe (cu) and its entropy Scu. We find that beyond dark energy, the
