Abstract

The recently reported evidence for the cosmic microwave background signature of inflationary gravitational waves is very tantalizing. I will discuss how the measurement is done, the evidence presented by BICEP2, the interpretation, and some of the criticisms of the arguments presented by BICEP2 that the signal is not dust-dominated. I will then review next steps to be taken with future CMB experiments and with galaxy surveys.
