Variation of the fine-structure constant caused by expansion of the Universe

Abstract: In this paper, we evaluate the fine-structure constant variation that should take place as the pseudo-Riemannian Universe expands and its curvature is changed adiabatically. Such variation of the fine-structure constant is attributed to an energy loss by an extended physical system (consisting of baryonic component and electromagnetic (EM) field) due to expansion of our Universe. Obtained ratio [Formula: see text] (per second) is only five times smaller than actually reported experimental limit on this value. … Show more

“…The any generalized inflation that evolves the angular momentum as described in previous section, would impact on electron spin. The electron spin 𝑆 with the value of This change rate is compatible with one of the related data was given by Shylakhter [ 35] and reviewed by Cardenas [36,37] which is reported as 4 × 10 −11 . This shows an amazing compatibility of BDM generalized inflation results and astronomical results of physical constants evolution.…”

“…Evidently this relation also holds for any other degree of freedoms. Like equation (36) using Wick rotation 𝑞𝑞 → 𝑙𝑙𝑖𝑖 and assuming the new parameter (e.g. 𝑥𝑥 ) instead of "time", and 𝑆𝑆 𝜕𝜕 instead of 𝐸𝐸, it is straight forward to conclude the relations for momentums:…”

“…Secondly, within the framework of geometry with asymmetric connections, the Planck constant calculated from the first principles (with measured cosmological parameters) coincides with its experimental value up to the second significant digit, that is, to the measurement errors of cosmological parameters (Hubble constant and cosmological constant) [38], whereas if it is calculated for the (pseudo-) Riemannian world, we find that the Planck constant differs by factor 3/2 from its exact value [39]. In this case we use the free EM field as a probe to test the geometry of space.…”
