Abstract We assume that our universe originated from highly excited and interacting strings with coupling constant g s = O ( 1 ) . Fluctuations of spacetime geometry are large in such strings and the physics dictating the emergence of a final spacetime configuration is not known. We propose that, nevertheless, it is determined by an entropic principle that the final spacetime configuration must have maximum entropy for a given amount of energy. This principle implies, under some assumptions… 
Non singular, bouncing M theory universe
We propose a set of equations as a simple model for non singular evolutions of a $10 + 1$ dimensional M theory universe. Our model uses ideas from Loop Quantum Cosmology and offers a solution to the

We study an M theory universe in the loop quantum cosmology—inspired models which involve a function, the choice of which leads to a variety of evolutions. The M theory universe is dominated by four
A class of LQC-inspired models for homogeneous, anisotropic cosmology in higher dimensional early universe
The dynamics of a $$(3 + 1)$$(3+1) dimensional homogeneous anisotropic universe is modified by loop quantum cosmology and, consequently, it has generically a big bounce in the past instead of a
Entropy of anisotropic universe and fractional branes
AbstractWe obtain the entropy of a homogeneous anisotropic universe applicable, by assumption, to the fractional branes in the universe in the model of Chowdhury and Mathur. The entropy for the 3 or
Relativistic stars with a linear equation of state: analogy with classical isothermal spheres and black holes
We complete our previous investigations concerning the structure and the stability of “isothermal” spheres in general relativity. This concerns objects that are described by a linear equation of
Consequences of U dualities for intersecting branes in the Universe
Abstract We consider N -charge, intersecting brane–antibrane configurations in M theory which are smeared uniformly in the common transverse space and may describe our universe. We study the
Spacetime Dimensionality from de Sitter Entropy
We argue that de Sitter universes with a small cosmological constant are entropically favored to have three spatial dimensions. The conclusion relies on the causal-patch description of de Sitter
Variety of $$(d + 1)$$(d+1) dimensional cosmological evolutions with and without bounce in a class of LQC-inspired models
The bouncing evolution of an universe in Loop Quantum Cosmology can be described very well by a set of effective equations, involving a function sin x. Recently, we have generalised these effective
Study of Early Universe in an M Theoretic Model
In this thesis we study early universe in the frame work of M theory. In particular We assume that the early universe is homogeneous, anisotropic, and is dominated by the mutually BPS 22'55'
Quantum graphity: A model of emergent locality
Quantum graphity is a background-independent model for emergent macroscopic locality, spatial geometry and matter. The states of the system correspond to dynamical graphs on N vertices. At high


M theory observables for cosmological space-times
We discuss the construction of the analog of an S-matrix for space-times that begin with a Big-Bang and asymptote to an FRW universe with nonnegative cosmological constant. When the cosmological
M-theory observables for cosmological space-times
We discuss the construction of the analog of an S-matrix for space-times that begin with a Big-Bang and asymptote to an FRW universe with nonnegative cosmological constant. When the cosmological
A stringy correspondence principle in cosmology
We study a d-dimensional FRW universe, containing a perfect fluid with p=wρ and 1d−1⩽w⩽1, and find a correspondence principle similar to that of Horowitz and Polchinski in the black hole case. This
Interaction rates in string gas cosmology
We study string interaction rates in the Brandenberger-Vafa scenario, the very early universe cosmology of a gas of strings. This cosmology starts with the assumption that all spatial dimensions are
Self-Gravitating Fundamental Strings and Black Holes
Abstract The configuration of typical highly excited (M≫Ms∼(α′)−1/2) string states is considered as the string coupling g is adiabatically increased. The size distribution of very massive single
Relaxing to three dimensions.
The idea is that the Universe will naturally select among possible vacua through its cosmological evolution, and the configuration with the biggest filling fraction is the likeliest, and this idea is applied to the question of the number of dimensions of space.
String Windings in the Early Universe
We study string dynamics in the early universe. Our motivation is the proposal of Brandenberger and Vafa that string winding modes may play a key role in decompactifying three spatial dimensions. We
Superstring gravity and the early universe
Ten-dimensional superstring theories have been proposed as candidates for a unified description of all the forces of nature. These theories reduce to Einstein gravity coupled to Yang-Mills
Elements of string cosmology
Abstract Aspects of string cosmology for critical and non-critical strings are discussed emphasizing the necessity to account for the dilaton dynamics for a proper incorporation of “large-small”
Correspondence principle for black holes and strings
For most black holes in string theory, the Schwarzschild radius in string units decreases as the string coupling is reduced. We formulate a correspondence principle, which states that (i) when the
