Time variation of fundamental constants, primordial nucleosynthesis, and the size of extra dimensions
Abstract
In theories with extra dimensions, the dependence of fundamental constants on the volume of the compact space allows one to use primordial nucleosynthesis to probe the structure of compact dimensions during the first few minutes after the big bang. Requiring the yield of primordial sup4He to be within acceptable limits, we find that in ten-dimensional superstring models the size of the extra dimensions during primordial nucleosynthesis must have been within 0.5% of their current value, while in Kaluza-Klein models the extra dimensions must have been within 1% of their current value.

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.
