Scale of gravity and the cosmological constant within a landscape

- Physics
- 2007

It is possible that the scale of gravity, parametrized by the apparent Planck mass, may obtain different values within different universes in an encompassing multiverse. We investigate the range over…

Anthropic Likelihood for the Cosmological Constant and the Primordial Density Perturbation Amplitude

- Physics
- 2012

Weinberg et al. calculated the anthropic likelihood of the cosmological constant using a model assuming that the number of observers is proportional to the total mass of gravitationally collapsed…

Density perturbations and the cosmological constant from inflationary landscapes

- Physics
- 2005

An anthropic understanding of the cosmological constant requires that the vacuum energy at late time scans from one patch of the universe to another. If the vacuum energy during inflation also scans,…

The Cosmological Constant Problem, an Inspiration for New Physics

- Physics
- 2006

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…

Predictions of the causal entropic principle for environmental conditions of the universe

- Physics
- 2008

The causal entropic principle has been proposed as an alternative to the anthropic principle for understanding the magnitude of the cosmological constant. In this approach, the probability to create…

What does inflation really predict?

- Physics
- 2005

If the inflaton potential has multiple minima, as may be expected in, e.g., the string theory ‘landscape’, inflation predicts a probability distribution for the cosmological parameters describing…

Multiple universes, cosmic coincidences, and other dark matters

- Physics
- 2004

Even when completely and consistently formulated, a fundamental theory of physics and cosmological boundary conditions may not give unambiguous and unique predictions for the universe we observe;…

Dimensionless constants, cosmology and other dark matters

- Physics
- 2006

We identify 31 dimensionless physical constants required by particle physics and cosmology, and emphasize that both microphysical constraints and selection effects might help elucidate their origin.…

Anthropic bounds on Λ from the no-boundary quantum state

- Physics
- 2013

We show that anthropic selection emerges inevitably in the general framework for prediction in quantum cosmology. There the predictions of anthropic reasoning depend on the prior implied by the…

Anthropic bound on the cosmological constant.

- PhysicsPhysical review letters
- 1987

It is argued here that in universes that do not recollapse, the only bound on the cosmological constantlambda is that it should not be so large as to prevent the formation of gravitationally bound states, and it turns out that the bound is quite large.

Cosmological constant and the time of its dominance

- Physics
- 1999

We explore a model in which the cosmological constant L and the density contrast at the time of recombination s rec are random variables, whose range and a priori probabilities are determined by the…

Likely Values of the Cosmological Constant

- Physics
- 1997

In theories in which the cosmological constant takes a variety of values in different "subuniverses," the probability distribution of its observed values is conditioned by the requirement that there…

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 Is the Cosmic Microwave Background Fluctuation Level 10−5?

We explore the qualitative changes that would occur if the amplitude Q ~ 10-5 of cosmological density fluctuations were different. If Q ≲ 10-6, the cosmological objects that form would have such low…

Cold big-bang cosmology as a counterexample to several anthropic arguments

A general Friedmann big-bang cosmology can be specified by fixing a half-dozen cosmological parameters such as the photon-to-baryon ratio ${\ensuremath{\eta}}_{\ensuremath{\gamma}},$ the cosmological…
