Some weeks back the media trumpeted the "smoking gun" claim the inflation had been confirmed by BICEP2 observations of B mode polarization in the CMB.
But the observations must, somehow, be accounted for, and the tension between BICEP2 and Planck must somehow be resolved.
Remarkably, one proposal suggests the tension between these observations can be resolved, if we abandon the Copernican Principle:
"Here we show that it is possible for a tensor fluctuation to produce a B mode in the CMB polarization without producing any temperature fluctuation nor E-mode polarization whatsoever. The argument is relatively straightforward given the total-angular- momentum (TAM) formalism we have developed in recent work . The only catch is that, as we show, the tensor fluctuation required to do this violates the Copernican principe; i.e., it implies that we occupy a preferred location in the Universe."
