Dirac's Large Numbers in Einstein-Dicke Cosmology — •Alexander Unzicker — Pestalozzi-Gymnasium München

The Large Number Hypothesis reflects a tantalizing observation that, according to Dirac, suggests 'a deep relation between cosmology and atomic physics'. It is shown that Diracs Hypotheses directly follow from a version of general relativity developed by Dicke (1957) that closely matches a precursor theory of general relativity by Einstein (1911) based on variable speed of light. Tragically, Dirac, Dicke and Einstein were unaware of the far-reaching similaritiy of their respective approaches.
