One of the leading astronomers and theorists of his generation, Arthur Stanley Eddington was an important early proponent of the general theory of relativity in both theory and experiment. Yet when his former student Georges Lemaitre suggested in 1927 that the well-known redshifts of the spiral nebulae could be explained in terms of a relativistic expansion of space, Eddington paid no attention for three years. In this paper, we consider the reasons Lemaitre's hypothesis attracted little… Expand

Redshifts and paradigm shifts; in defence of Hubble's Law
We consider the recent proposal by the International Astronomical Union and others to rename Hubble's law as the Hubble-Lemaitre law in order to recognise the scientific contributions of GeorgesExpand

No other scientist may have had a greater impact on modern cosmology than the Belgian physicist, astronomer and priest Georges Lemaître. In 1927 he predicted the expansion of the universe on theExpand
Who discovered the expanding universe
Who discovered the expanding universe? Was it Hubble, or Lema\^itre, or was it just the end result of a long series of investigations? In this article we summarise the main steps and contributionsExpand
"The Waters I am Entering No One yet Has Crossed": Alexander Friedman and the Origins of Modern Cosmology
Ninety years ago, in 1922, Alexander Friedman (1888-1925) demonstrated for the first time that the General Relativity equations admit non-static solutions and thus the Universe may expand, contract,Expand
The Origins of the Velocity-Distance Relation
Introduction In this paper we shall consider the establishment in the late 1920s and early 1930s of the linear relation between a galaxy's distance and the redshift of its spectral lines: theExpand
Slipher, galaxies, and cosmological velocity fields
By 1917, V.M. Slipher had singlehandedly established a tendency for 'spiral nebulae' to be redshifted (21 out of 25 cases). From a modern perspective, it could seem surprising that the expansion ofExpand
