Seeds of Cosmic Structure: Quantum Fluctuations in the Primordial Soup
Professor, Fermilab & Univ. of Chicago
If the early universe had a phase of rapid expansion known as inflation, then the pattern of small quantum fluctuations may be imprinted on the universe in the form of large scale structure and fluctuations in the background radiation temperature. In the talk I will explain how something as small as quantum fluctuations can lead to something as large as a galaxy, and review observational tests of the idea.
