Implications of a cosmological constant varying asR−2

Chen, Wei, Wu, Yong-Shi·1990·Physical Review D

Abstract

We advocate the possibility that the (effective) cosmological constant \ensuremath{\Lambda} varies in time as ${R}^{\mathrm{\ensuremath{-}}2}$, R being the scale factor of our expanding Universe. This behavior can be obtained under some simple and general assumptions in conformity with quantum cosmology. After pointing out several advantages worth noticing, we show that such a time-varying \ensuremath{\Lambda} leads to no conflict with existing observations. However, it does change the predictions of the standard cosmology in the matter-dominated epoch and alleviates some problems in reconciling observations with the inflationary scenario. In particular, this ``medium'' time variation of \ensuremath{\Lambda} leads to creation of matter with a rate at present which is comparable to that in the steady-state cosmology.

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.
