The Harvard-Smithsonian Center for Astrophysics has news so big it announced that it would announce something. While we await the press conference (streamed live at 12 noon on Monday!), cosmologists everywhere are gossiping about what that news could be.

If gravitational waves have been observed, it most likely was done by the Background Imaging of Cosmic Extragalactic Polarization (Bicep) telescope at the south pole. It stared at the cosmic microwave background radiation from 2003 to 2008, but it takes a long time to process and analyze the data when looking for a faint signal in a lot of noise.
