# The Cosmological Constant

@article{Carroll2001TheCC, title={The Cosmological Constant}, author={S. Carroll}, journal={Living Reviews in Relativity}, year={2001}, 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

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…

A Note on the Cosmic Neutrino Background and the Cosmological Constant

- Physics

AbstractWe point out that by considering the cosmic neutrino background and
the recently obtained neutrino mass, we can deduce the correct value
of the cosmological constant, thus resolving the so…

Accelerating Universe, Cosmological Constant and Dark Energy

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

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
