We compute the expected value of the cosmological constant in our universe from the Causal Entropic Principle. Since observers must obey the laws of thermodynamics and causality, it asserts that physical parameters are most likely to be found in the range of values for which the total entropy production within a causally connected region is maximized. Despite the absence of more explicit anthropic criteria, the resulting probability distribution turns out to be in excellent agreement with… 
Predictions of the causal entropic principle for environmental conditions of the universe
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
Landscape predictions from cosmological vacuum selection
In Bousso-Polchinski models with hundreds of fluxes, we compute the effects of cosmological dynamics on the probability distribution of landscape vacua. Starting from generic initial conditions, we

Inflationary Cosmology 1
I give a general review of the history of inflationary cosmology and of its present status.


Positive vacuum energy and the N-bound
We argue that the total observable entropy is bounded by the inverse of the cosmological constant. This holds for all space-times with a positive cosmological constant, including cosmologies
Cosmological constant and the time of its dominance
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
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
Cosmology and the S matrix
We study conditions for the existence of asymptotic observables in cosmology. With the exception of de Sitter space, the thermal properties of accelerating universes permit arbitrarily long
An observational test for the anthropic origin of the cosmological constant
The existence of multiple regions of space beyond the observable Universe (within the so-called multiverse) where the vacuum energy density takes different values has been postulated as an

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.
Quantization of four-form fluxes and dynamical neutralization of the cosmological constant
A four-form gauge flux makes a variable contribution to the cosmological constant. This has often been assumed to take continuous values, but we argue that it has a generalized Dirac quantization
Probabilities in the inflationary multiverse
Inflationary cosmology leads to the picture of a ‘multiverse’, involving an infinite number of (spatially infinite) post-inflationary thermalized regions, called pocket universes. In the context of
SPECIAL ISSUE: Cosmological transitions with changes in the signature of the metric
It is conjectured that there exist states of the physical continuum which include regions with different signatures of the metric and that the observed Universe and an infinite number of other
