How did structures such as clusters of galaxies arise in the Universe? This talk is an intellectual history of attempts to understand the origin of structure. I consider the contributions of the ancients, Newton, the Herschels, Isaac Roberts, Vesto Slipher, Einstein, Georges Lemaître and Edwin Hubble in the first half. The focus then changes to the post-1964 situation, with the discovery of the cosmic microwave background, and the emergence of a consensus viewpoint for the nature of the Hot Big Bang. The presentation concludes with the role of dark matter and dark energy.

The talk summarises the main themes of the book Heart of Darkness, by Jeremiah P Ostriker and Simon Mitton linkhere
