Tegmark Abstract

Imaging Inflation with Cosmic Microwave Background Polarization
Max Tegmark (Massachusetts Institute of Technology)

One of the most spectacular scientific breakthroughs in past decades was using measurements of the fluctuations in the cosmic microwave background (CMB) to test precisely our understanding of the history and composition of the Universe. I describe what I view as the logical next step for CMB research: using precision polarization measurements to learn about ultra-high-energy physics and the Big Bang itself.
