Ever since the BICEP2 team reported their findings — and evidence for B-mode polarization of the cosmic microwave background indicating gravitational waves from inflation — the physics world has never been the same.
Recently, there have been rumors that perhaps this B-mode signal is due to the Milky Way, and not due to inflation after all. If this does turn out to be the case, what does this mean for cosmic inflation? Is it still on rock-solid footing, or will it come tumbling down like a house of cards?
