Time variation of the fine structure constant in the early universe and the Bekenstein model
Aims. We calculate bounds on the variation of the fine structure constant at the time of primordial nucleosynthesis and at the time of neutral hydrogen formation. We use these bounds and other bounds from the late universe to test Bekenstein model. Methods. We modify the Kawano code, CAMB and CosmoMC in order to include the possible variation of the fine structure constant. We use observational...
متن کاملThe Holistic Universe and the Variation of the Fine Structure Constant
Inaba recently used a simple model to suggest that Quantum Theory can result from a fluctuation in the cosmos. In this note we confirm this conclusion from a different and more general point of view. We then argue that this provides an explanation for the recently observed variation of the fine structure constant.
متن کاملAging of the Universe and the fine structure constant
In this paper the aging of the Universe is investigated in the frame of quantum hyperbolic heat transport equation. For the open universe, when t → ∞, h̄ → ∞, c → 0 and fine structure constant, α, is constant.
متن کاملVariable Fine Structure Constant from Maximal-acceleration Phase Space Relativity
Recently, we presented a new physical model that links the maximum speed of light with the minimal Planck scale into a maximal-acceleration Relativity principle in the spacetime tangent bundle and in phase spaces (cotangent bundle). The maximal proper-acceleration bound is a = c/Λ in full agreement with the old predictions of Caianiello, the Finslerian geometry point of view of Brandt and more ...
متن کاملFine Structure Anomalies and Search for Variation of the Fine Structure Constant in Laboratory Experiments
Configuration interaction in many-electron atoms may cause anomalies in the fine structure which make the intervals small and very sensitive to variation of the fine structure constant. Repeated precision measurements of these intervals over long period of time can put strong constrain on possible time variation of the fine structure constant. We consider the 5p 3P2,1,0 fine structure multiplet...
