Abstract

Exploring the recent expansion history of the universe promises insights into the cosmological model, the nature of dark energy, and potentially clues to high energy physics theories and gravitation. We examine the extent to which precision distance-redshift observations can map out the history, including the acceleration-deceleration transition, and the components and equations of state of the energy density. We consider the ability to distinguish between various dynamical scalar field models for the dark energy, as well as higher dimension and alternate gravity theories. Finally, we present a new, advantageous parametrization for the study of dark energy.

  • In this construction, a single scalar field drives both late-time acceleration and ekpyrotic smoothing at the background level, while the spin-torsion sector supplies the repulsive ρs ∝ a^-6 contribution that regulates the high-density regime, instead of introducing separate ingredients for each phase.

    “In this restricted sense the construction is a direct extension of familiar quintessence dynamics [31,32]: a single scalar field drives both late-time acceleration and ekpyrotic smoothing at the background level, while the spin-torsion sector supplies the repulsive ρ s ∝ a -6 contribution that regulates the high-density regime, instead of introducing separate ingredients for each phase.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
