Hubble Law or Hubble-Lema\^itre Law? The IAU Resolution

History and Philosophy of Physics 2018-09-10 v1

Abstract

The Hubble law, widely considered the first observational basis for the expansion of the universe, may in the future be known as the Hubble-Lema\^itre law. This is what the General Assembly of the International Astronomical Union recommended at its recent meeting in Vienna. However, the resolution in favour of a renamed law is problematic in so far as concerns its arguments based on the history of cosmology in the relevant period from about 1927 to the early 1930s. A critical examination of the resolution reveals flaws of a non-trivial nature. The purpose of this note is to highlight these problems and to provide a better historically informed background for the voting among the union's members, which in a few months' time will result in either a confirmation or a rejection of the decision made by the General Assembly.
