Title: "Echoes of the Big Bang"

Intended Audience(s): Public
Categories: Lectures & Seminars

Abstract: A prediction of an inflationary epoch in the early universe -- responsible for the *bang* in the Big Bang -- is a spectrum of primordial gravitational waves. In this talk, we review the mechanism that creates these waves, deconstruct the tell-tale imprint that these relics leave on the cosmic microwave background, and summarize the observational status. We also report on recent work suggesting these gravitational waves may have a preferred handedness.
