Inflation made the news in a big way last spring when members of the BICEP2 collaboration announced they had measured a particular signature of inflation: the polarization of light due to turbulent gravitational disturbances from when the Universe was only a fraction of a second old. Last week, I led a session on BICEP2 at the National Association of Science Writers/Council for the Advancement of Science Writing (NASW/CASW) national meeting, featuring Johns Hopkins cosmologist Marc Kamionkowski and WIRED editor Betsy Mason. Video from the session will eventually be available, and no doubt people will cover the session for blogs and other outlets, so the conversation is ongoing.
Meanwhile, my newest CosmoAcademy class will do its best to cover our current knowledge about inflation, the evidence for it, and alternative ideas. The class starts tomorrow, and we still have a few spaces left — sign up today!
