    Description
    The recent detection by the BICEP2 telescope of a "B-mode polarisation" signal in the cosmic microwave background has been hailed as the first direct evidence that the early universe underwent a period of inflation which generated primordial gravitational waves. I will argue that it may instead be Galactic foreground emission, in particular from magnetised dust grains in an old supernova remnant in the BICEP2 field of view.
