Cosmological constant—the weight of the vacuum
Open accessAbstract
Recent cosmological observations suggest the existence ofa positive cosmological constantwith the magnitude � (G˝=c 3 ) ≈ 10 −123 . This review discusses several aspects ofthe cosmological constant both f rom the cosmological (Sections 1- 6) and .eld theoretical (Sections 7-11) perspectives. After a brief introduction to the key issues related to cosmological constant and a historical overview, a summary ofthe kinematics and dynamics ofthe standard Friedmann model ofthe universe is provided. The observational evidence for cosmological constant, especially from the supernova results, and the constraints from the age of the universe, structure formation, Cosmic Microwave Background Radiation (CMBR) anisotropies and a few others are described in detail, followed by a discussion of the theoretical models (quintessence, tachyonic scalar .eld, :::) from di4erent perspectives. The latter part of the review (Sections 7-11) concentrates on more conceptual and f aspects ofthe cosmological constant like some alternative interpretations ofthe cosmological constant, relaxation mechanisms to reduce the cosmological constant to the currently observed value, the geometrical structure ofthe de Sitter spacetime, thermodynamics ofthe de Sitter universe and the role of string theory in the cosmological constant problem. c

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.
