The cosmological study is misleading. Its argument is that *if* the recent BICEP2 “observation” of B-mode polarisation is correct, *then* the universe should not exist. However, serious questions have been raised about the BICEP2 finding. In particular, it appears that the BICEP people might have seriously underestimated B-mode polarisation from ordinary cosmic dust–a fact which, if it turns out to indeed be the case (this isn’t clear yet), would render the new paper (“the universe shouldn’t exist) a red herring.
