# The Cosmological Constant

@article{Carroll2000TheCC, title={The Cosmological Constant}, author={S. Carroll}, journal={Living Reviews in Relativity}, year={2000}, volume={4} }

This is a review of the physics and cosmology of the cosmological constant. Focusing on recent developments, I present a pedagogical overview of cosmology in the presence of a cosmological constant, observational constraints on its magnitude, and the physics of a small (and potentially nonzero) vacuum energy.

### Value of the Cosmological Constant in the Cosmological Relativity Theory

- Physics
- 2001

It is shown that the cosmological relativity theory predicts the value Λ = 1.934 × 10−35s−2 for the cosmological constant. This value of Λ is in excellent agreement with the measurements recently…

### Gauge-dependent cosmological 'constant'

- Physics
- 2004

When the cosmological constant of spacetime is derived from the 5D induced-matter theory of gravity, we show that a simple gauge transformation changes it to a variable measure of the vacuum which is…

### Accelerating Universe, Cosmological Constant and Dark Energy

- Physics
- 2001

We present a space-velocity theory of gravitation in a 4-dimensional curved space. The solutions of the field equations yield 3 possibilities for the universe expansion but only the accelerating one…

### A SOLUTION TO THE COSMOLOGICAL CONSTANT PROBLEM

- Physics
- 2005

According to general relativity, the present analysis shows on geometrical grounds that the cosmological constant problem is an artifact due to the unfounded link of this fundamental constant to…

### Cosmological constant problems and the renormalization group

- Physics
- 2006

The cosmological constant problem emerges when quantum field theory is applied to the gravitational theory, due to the enormous magnitude of the induced energy of the vacuum. The unique known…

### BRANE UNIVERSES AND THE COSMOLOGICAL CONSTANT

- Physics, Philosophy
- 2005

The cosmological constant problem and brane universes are reviewed briefly. We discuss how the cosmological constant problem manifests itself in various scenarios for brane universes. We review…

### Inhomogeneous cosmological models in the presence of massless scalar fields

- Physics
- 2010

Non-static inhomogeneous cosmological models are obtained in general relativity for the case of a plane symmetric massless scalar field with cosmological constant Λ, when the source of the…

### A note on the local cosmological constant and the dark energy coincidence problem

- Physics
- 2006

It has been suggested that the dark energy coincidence problem could be interpreted as a possible link between the cosmological constant and a massive graviton. We show that by using this link and…

### The cosmological constant

- Physics
- 2003

We discuss issues related with the cosmological constant problem in the light of recent observations which tend to indicate that the expansion of the universe is presently undergoing an acceleration.…

### Model of a decaying cosmological constant.

- PhysicsPhysical review. D, Particles and fields
- 1990

A theoretical model is proposed for decay of the cosmological constant, allowing a natural interpretation that the cosmological constant is small at present simply because our Universe is old. The…

### The cosmological constant is back

- Physics
- 1995

A diverse set of observations now compellingly suggest that the universe possesses a nonzero cosmological constant. In the context of quantum-field theory a cosmological constant corresponds to the…

The vanishing of the cosmological constant and the absence of a massless dilaton might be explained by a duality between a supersymmetric string vacuum in three dimensions and a nonsupersymmetric…

### The Cosmological Constant Problem

- Physics

Astronomical observations indicate that the cosmological constant is many orders of magnitude smaller than estimated in modern theories of elementary particles. After a brief review of the history of…

### Spontaneous Decay of the effective Cosmological Constant

- Physics
- 1998

We discuss the notion that quantum fields may induce an effective time-dependent cosmological constant which decays from a large initial value. It is shown that such cosmological models are viable in…

This is the written version of a talk given at the Santa Barbara Workshop on Supersymmetry in December of 1995. It summarizes a collection of results on superstring cosmology obtained by the author…

### Theories of the Cosmological Constant

- Physics

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.
