(abridged) Both fundamental constants that describe the laws of physics and cosmological parameters that determine the cosmic properties must fall within a range of values in order for the universe to develop astrophysical structures and ultimately support life. This paper reviews current constraints on these quantities. The standard model of particle physics contains both coupling constants and particle masses, and the allowed ranges of these parameters are discussed first. We then consider… Expand
Multiverse Predictions for Habitability: The Number of Stars and Their Properties
In a multiverse setting, we expect to be situated in a universe that is exceptionally good at producing life. Though the conditions for what life needs to arise and thrive are currently unknown, manyExpand
An update on fine-tunings in the triple-alpha process
The triple-alpha process, whereby evolved stars create carbon and oxygen, is believed to be fine-tuned to a high degree. Such fine-tuning is suggested by the unusually strong temperature dependenceExpand
The flatness problem and the age of the Universe
Several authors have made claims, none of which has been rebutted, that the flatness problem, as formulated by Dicke and Peebles, is not really a problem but rather a misunderstanding. Nevertheless,Expand
Life, the universe and the hidden meaning of everything
It is found that with plausible additional assumptions Sciama’s signature would appear to reverse: Were the authors' universe random, it could give the false impression of being intelligently designed, with the fundamental constants appearing to be fine tuned to a strong probability for life to emerge and be maintained.

Multiverse Theories
If the laws of nature are fine-tuned for life, can we infer other universes with different laws? How could we even test such a theory without empirical access to those distant places? Can we believeExpand
Arguments against the flatness problem in classical cosmology: a review
Several authors (including myself) have made claims, none of which has been convincingly rebutted, that the flatness problem, as formulated by Dicke and Peebles, is not really a problem but rather aExpand
Dynamics of genetic code evolution: The emergence of universality.
This work exploits the mechanism of horizontal gene transfer to demonstrate convergence of the genetic code to a near universal solution, and reproduces and analyzes the algorithm as a dynamical system to find that there is a direct link to mutation rate. Expand
Dynamics of genetic code evolution: The emergence of universality
The algorithm of Vetsigian et al. provides a solution that is both optimal and universal and it is shown that by allowing specific parameters to vary with time, the algorithm converges much faster to a universal solution. Expand
Effects of bound diprotons and enhanced nuclear reaction rates on stellar evolution
Deuterium represents the only bound isotope in the universe with atomic mass number A = 2. Motivated by the possibility of other universes, where the strong force could be stronger, this paperExpand
Is cosmological tuning fine or coarse?
The fine-tuning of the universe for life, the idea that the constants of nature (or ratios between them) must belong to very small intervals in order for life to exist, has been debated by scientistsExpand


Planets in Other Universes: Habitability constraints on density fluctuations and galactic structure
Motivated by the possibility that different versions of the laws of physics could be realized within other universes, this paper delineates the galactic parameters that allow for habitable planetsExpand
Stars in other universes: stellar structure with different fundamental constants
Motivated by the possible existence of other universes, with possible variations in the laws of physics, this paper explores the parameter space of fundamental constants that allows for the existenceExpand
The asymptotic form of cosmic structure : Small-scale power and accretion history
We explore the effects of small-scale structure on the formation and equilibrium of dark matter halos in a universe dominated by vacuum energy. We present the results of a suite of four N-bodyExpand
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 lowExpand
Constraints on Alternate Universes: Stars and habitable planets with different fundamental constants
This paper develops constraints on the values of the fundamental constants that allow universes to be habitable. We focus on the fine structure constant $\alpha$ and the gravitational structureExpand
Cosmological Formation of Low-Mass Objects
We investigate the early formation of bound objects with masses comparable to the cosmological Jeans mass (10^5 solar masses). We follow the growth of isolated spherically symmetric density peaksExpand
Nuclear processes in other universes: Varying the strength of the weak force
Motivated by the possibility that the laws of physics could be different in other regions of space-time, we consider nuclear processes in universes where the weak interaction is either stronger orExpand

The relations between the constants, the tests of the local position invariance and of the universality of free fall are detailed, and the unification mechanisms and the relation between the variation of different constants are described. Expand
Astronomical reach of fundamental physics
Using basic physical arguments, the characteristic masses and sizes of important objects in the universe are derived by dimensional and physical analysis in terms of just a few fundamental constants to expose the deep interrelationships imposed by nature between disparate realms of the universe.

Why the Universe is Just So
Some properties of the world are fixed by physics derived from mathematical symmetries, while others are selected from an ensemble of possibilities. Several successes and failures of ‘‘anthropic’’Expand
