Already the alleged discovery of not only primordial gravitational waves but also the big bang era of inflation (which I discussed in Has the ‘smoking gun’ of the ‘big bang’ been found? and also in this blog, only a little over a week ago) has been questioned in a paper1 by leading cosmologists. This is in a paper, submitted to the preprint archive (arXiv.org) on March 20th, 2014, just three days after the press release (on March 17th) of the “discovery” by the BICEP2 Collaboration team.
On March 25th a press item appeared on phys.org quoting these cosmologists and entitled ‘Cosmologists cast doubt on inflation evidence’, with a storyline saying
Some theorists are advising that we “put the champagne back in the fridge”… at least for now.2
