Nature is characterised via a few actual legislation and primary dimensionless couplings. those confirm the houses of our actual universe, from the dimensions of atoms, cells and mountains to the final word destiny of the universe as an entire. but it is extremely extraordinary how little we all know approximately them. The fidelity of actual legislation is likely one of the cornerstones of the clinical study procedure, yet for basic couplings this is often an assumption without different justification than a ancient assumption. there's no 'theory of constants' describing their position within the underlying theories and the way they relate to each other or what number of them are really basic.

Studying the behaviour of those amounts during the historical past of the universe is a good option to probe primary physics. This explains why the ESA and ESO contain various basic constants between their key technological know-how drivers for the following iteration of amenities. This symposium mentioned the cutting-edge within the box, in addition to the major advancements expected for the arriving years.

Vucetich Abstract There are several very different motivations for studying the variation of fundamental constants. They may provide a connection between cosmology and particle physics due to the coincidence of large dimensionless numbers arising from the combination of different physical constants. Bekenstein’s variable charge model is very attractive because it is based on very general assumptions: covariance, gauge invariance, causality and time-reversal invariance of electromagnetism. The generality of its assumptions guarantee the applicability of the scheme to other gauge interactions such as the strong forces.

G. be in conflict with constraints from fifth force experiments, Big Bang Nucleosynthesis (BBN) or overclosure bounds. A simple way to safely avoid all these types of problems would be to ensure that the moduli are sufficiently heavy, say of order 30 : : : 100 TeV or higher. , [6] and references therein), which, in many supersymmetry breaking scenarios would be below the above-mentioned energy regime. g. [5, 18, 23, 29] for reviews). The moduli masses this induces are usually not connected to the gravitino mass and can easily be made sufficiently large to avoid all the above moduli problems.
