Space is not a boring static stage on which events unfold over time, but a dynamic entity with curvature, fluctuations, and a rich life of its own. Spectacular measurements of the cosmic microwave background, gravitational lensing, type Ia supernovae, large-scale structure, spectra of the Lyman α forest, stellar dynamics, and x-ray binaries are probing the properties of spacetime over 22 orders of magnitude in scale. Current measurements are consistent with an infinite flat everlasting universe… 

Strangeness, cosmological cold dark matter and dark energy

It is now believed that the universe is composed of a small amount of the normal luminous matter, a substantial amount of matter (cold dark matter (CDM)) which is non-luminous and a large amount of

Separating the early universe from the late universe: Cosmological parameter estimation beyond the black box

We present a method for measuring the cosmic matter budget without assumptions about speculative Early Universe physics, and for measuring the primordial power spectrum P*(k) non-parametrically,

The angular size–redshift relation in power-law cosmologies

A linear evolution of the cosmological scale factor is a feature in several models designed to solve the cosmological constant problem via a coupling between scalar or tensor classical fields to the

What does inflation really predict?

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

Cosmic growth history and expansion history

Author(s): Linder, Eric V. | Abstract: The cosmic expansion history tests the dynamics of the global evolution of the universe and its energy density contents, while the cosmic growth history tests

Resource Letter DEAU-1: Dark energy and the accelerating universe

This Resource Letter provides a guide to the literature on dark energy and the accelerating universe. It is intended to be of use to researchers, teachers, and students at several levels. Journal

The Short Spectacular Life of a Superstar

Supernovae are spectacular events--the death throes of stars that can be seen across the universe--and they can leave behind puzzling remnants in the form of neutron stars or black holes. In his

The microsecond old universe — Relics of QCD phase transition

It is entirely plausible under reasonable conditions, that a first-order QCD phase transition occurred from quarks to hadrons when the universe was about a microsecond old. Relics, if there be any,

The Ekpyrotic universe: Colliding branes and the origin of the hot big bang

We propose a cosmological scenario in which the hot big bang universe is produced by the collision of a brane in the bulk space with a bounding orbifold plane, beginning from an otherwise cold,

Measuring the metric: A parametrized post-Friedmannian approach to the cosmic dark energy problem

We argue for a ``parametrized post-Friedmanian'' approach to linear cosmology, where the history of expansion and perturbation growth is measured without assuming that the Einstein Field Equations

PROBING DARK ENERGY: METHODS AND STRATEGIES

The presence of dark energy in the Universe is inferred directly from the accelerated expansion of the Universe, and indirectly, from measurements of cosmic microwave background (CMB) anisotropy.

Cosmology - The cosmic triangle: Revealing the state of the universe

The cosmic triangle is introduced as a way of representing the past, present and future status of the universe. Our current location within the cosmic triangle is determined by the answers to three

Structure Formation with Generalized Dark Matter

The next generation of cosmic microwave background (CMB) experiments, galaxy surveys, and high-redshift observations can potentially determine the nature of the dark matter observationally. With this

Constraints on the Long-Range Properties of Gravity from Weak Gravitational Lensing

Weak gravitational lensing provides a means of testing the long-range properties of gravity. Current measurements are consistent with standard Newtonian gravity and inconsistent with substantial

TLDR
The picture that has emerged from this line of development is that a small closed universe can spontaneously nucleate out of nothing, where by ‘nothing’ I mean a state with no classical space and time.

Microwave background anisotropy in a toroidal universe.

TLDR
Large-scale cosmic microwave background temperature fluctuations are calculated for a universe with the topology of a 3-torus and it is found that a topologically ``small'' universe is no longer an interesting cosmological model.

Detection of weak gravitational lensing distortions of distant galaxies by cosmic dark matter at large scales

TLDR
The detection of cosmic shear on angular scales of up to half a degree is reported using 145,000 galaxies and along three separate lines of sight and it is found that the dark matter is distributed in a manner consistent with either an open universe, or a flat universe that is dominated by a cosmological constant.
