The Cosmological Constant Problem, an Inspiration for New Physics
We have critically compared different approaches to the cosmological constant problem, which is at the edge of elementary particle physics and cosmology. This problem is deeply connected with the…

Geometric origin of cosmological time asymmetry in quantum cosmology
Gravitational coupling and dynamical reduction of the cosmological constant
We introduce a dynamical model to reduce a large cosmological constant to a sufficiently small value. The basic ingredient in this model is a distinction which has been made between the two unit…
Quantum gravity with a positive cosmological constant
A quantum theory of gravity is described in the case of a positive cosmological constant in 3 + 1 dimensions. Both old and new results are described, which support the case that loop quantum gravity…
The Cosmological Constant Problem, Dark Energy, and the Landscape of String Theory
In this colloquium-level account, I describe the cosmological constant problem: why is the energy of empty space at least 60 orders of magnitude smaller than several known contributions to it from…
Prediction in Quantum Cosmology
As far as we know them, the fundamental laws of physics are quantum mechanical in nature. If these laws apply to the universe as a whole, then there must be a description of the universe in quantum…
The Interpretation of quantum cosmological models
We consider the problem of extracting physical predictions from the wave function of the universe in quantum cosmological models. We state the features of quantum cosmology an interpretational scheme…
Quantum gravity, the origin of time and time's arrow
The local Lorentz and diffeomorphism symmetries of Einstein's gravitational theory are spontaneously broken by a Higgs mechanism by invoking a phase transition in the early universe, at a critical…
de Sitter Radiation and Backreaction in Quantum Cosmology
We explore the quantum cosmology description of the de Sitter (dS) radiation and its backreaction to dS space, inherent in the wave function of the Wheeler-DeWitt equation for pure gravity with a…

The unpredictability of quantum gravity
Quantum gravity seems to introduce a new level of unpredictability into physics over and above that normally associated with the uncertainty principle. This is because the metric of spacetime can…
Creation of open universes from de Sitter space
Hawking1,2 has shown that event horizons produce thermal radiation. I propose here a new cosmological model which has an early event horizon and in which the observed3 cosmic microwave background…

Relaxation of the Cosmological Constant
We present a classical field theory which has a long epoch resembling the Friedmann universe despite the presence of a large negative cosmological constant. In its most plausible realization the…

Canonical quantization of 1+1 dimensional gravity
Based on Polyakov's evaluation of the Fadeev-Popov determinant for (1+1)-dimensional gravity in the conformal gauge we formulate a canonical quantization in the synchronous gauge. We find that the…
Interacting quantum fields around a black hole
If one studies interacting fields on a black hole background using ordinary Feynman diagrams, one is faced with a problem of what to do with lines that cross the horizon. To avoid this difficulty a…
Is the Universe a Vacuum Fluctuation?
The author proposes a big bang model in which our Universe is a fluctuation of the vacuum, in the sense of quantum field theory. The model predicts a Universe which is homogeneous, isotropic and…
Cosmology for Grand Unified Theories with Radiatively Induced Symmetry Breaking
The treatment of first-order phase transitions for standard grand unified theories is shown to break down for models with radiatively induced spontaneous symmetry breaking. It is argued that proper…
