Dirac's Way to Quantum Gravity — •Alexander Unzicker — Pestalozzi-Gymnasium München

It is shown that Dirac's Large Number Hypotheses are equivalent to a numerical coincidence regarding Planck's constant, the speed of light and the mass and radius of the proton. Though this observation goes back to Finkelnburg (1947), the proton radius puzzle (Pohl, 2010) has augmented its possible relevance. As it happened with many other fundamental problems, a numerical coincidence may be the key to the quantum gravity conundrum.
