London: Macmillan & Sons, 1967. 1st Edition. FIRST EDITION IN ORIGINAL WRAPPERS. Shortly after Wilkinson and Partridge published the first tentative sightings of CMB anistropies, Joseph Silk, in this paper, demonstrated that only very large density irregularities in the early universe (larger than 1,013 solar masses) would survive and be visible in the CMB. We separately offer the Wilkinson & Partridge paper as well as the related Rees & Sciama paper.

The Gruber Foundation, writing about Silk in their Cosmology Prize Laureate Profile, noted the following: ““The validation of the Big Bang interpretation of the universe arrived, in 1965, just as a 22-year-old Joseph Silk was entering the field of cosmology. The discovery came in the form of an observation of microwave radiation suffusing all of space in every direction. This cosmic microwave background, or CMB, matched a theoretical prediction of what temperature a universe born in a Big Bang would have reached today if the universe had been expanding and cooling for 13 billion years. The radiation, however, was featureless—yet features are what a CMB would need if it’s going to grow into a universe full of galaxies.

“Presumably more precise observations would detect those irregularities, and in 1967 and 1968 [in a separate paper], Silk calculated that when observations of the CMB attained a far more subtle level of precision, those features would emerge in the form of infinitesimal temperature fluctuations” (Gruber Foundation Cosmology Prize Laureate Profile).
