The role of initial conditions in the universe formation
The dependence of low-energy physics on initial conditions in the framework of multidimensional gravity is discussed. It is shown that the observable symmetries could be a result of specific
The emperor's last clothes? Overlooking the string theory landscape
We are in the middle of a remarkable paradigm shift in particle physics, a shift of opinion that occurred so slowly that some even try to deny that they changed their minds at all. It concerns a very
Editorial note to: Brandon Carter, Large number coincidences and the anthropic principle in cosmology
This is an editorial note to accompany reprinting as a Golden Oldie in the Journal of General Relativity and Gravitation of the famous paper by Brandon Carter on the anthropic principle in cosmology
The Inevitability of Fine Tuning in a Complex Universe
Why should the universe need to be fine tuned? The thesis is presented that parameter sensitivity arises as a natural consequence of the mathematics of dynamical systems with complex outcomes. Hence,
Life, Intelligence, and the Selection of Universes
Complexity and life as we know it depend crucially on the laws and constants of nature as well as the boundary conditions, which seem at least partly “fine-tuned.” That deserves an explanation: Why
Varying Constants, Gravitation and Cosmology

The relations between the constants, the tests of the local position invariance and of the universality of free fall are detailed, and the unification mechanisms and the relation between the variation of different constants are described.
Hodge Duality and Cosmological Constant
We present a simple mechanism to eliminate cosmological constants both in supersymmetric and non-supersymmetric theories. This mechanism is based on the Hodge (Poincare) duality between a 0-form and
The degree of fine-tuning in our universe — and others
The universe formation by space reduction cascades with random initial parameters
In this paper we discuss the creation of our universe using the idea of extra dimensions. The initial, multidimensional Lagrangian contains only metric tensor. We have found many sets of the


Quantum creation of the inflationary universe
SummaryIt is shown that the process of quantum creation of the universe in a wide class of elementary-particle theories with a large probability leads to creation of an exponentially expanding
On the cosmological constant problem
The anthropic principle and the structure of the physical world
The basic features of galaxies, stars, planets and the everyday world are essentially determined by a few microphysical constants and by the effects of gravitation. Many interrelations between
The Cosmological Constant Problems
The old cosmological constant problem is to understand why the vacuum energy is so small; the new problem is to understand why it is comparable to the present mass density. Several approaches to
Theories of the Cosmological Constant
This talk describes how to calculate the probability distribution of the observed cosmological constant incosmological theories with a large number of subuniverses (i. e., different expanding regions, or different terms in the wave function of the universe) in which this constant takes different values.
Quantum Creation of Universes
A cosmological wave function describing the tunneling of the Universe from "nothing" into a de Sitter space is found in a simple minisuperspace model. The tunneling probability is proportional to
The Anthropic Cosmological Principle
Is there any connection between the vastness of the universes of stars and galaxies and the existence of life on a small planet out in the suburbs of the Milky Way? This book shows that there is. In
Why the Universe is Just So
Some properties of the world are fixed by physics derived from mathematical symmetries, while others are selected from an ensemble of possibilities. Several successes and failures of ‘‘anthropic’’
Dirac's Cosmology and Mach's Principle
THE dimensionless gravitational coupling constant with mp the mass of some elementary particle, for definiteness taken as the proton, is such a small number that its significance has long been
