Variable Speed of Light and its Cosmological Implications — •Alexander Unzicker — Pestalozzi-Gymnasium München

Variable speed of light (VSL) formulations of general relativity have been shown to be in accordance with the four classical tests. The approach presented here combines Dicke’s (1953) theory (different from Brans-Dicke) with de Broglies phase velocity formula c2= vV in order to obtain equations of motion from a variational principle of minimum phase. This realizes Mach’s principle with variable time and lenght scales. The cosmological consequences would explain Dirac’s observation on the total number of particles in the universe known as Large Number Hypothesis. Furthermore, it is discussed how small accelerations on the cosmological scale 10−10 m/s2 can appear.
