There was a paper last year by Ali and Das, "Cosmology from quantum potential," http://arxiv.org/abs/1404.3093 . Some elements of the popular media seem to be picking up on it and describing it as a paper that says that the big bang didn't exist, e.g., http://www.glennbeck.com/2015/02/10/watch-the-big-bang-never-happened/ . Some of my colleagues have been hearing about this from their students.
I'm not a quantum gravity specialist, but from a brief inspection it looks like the paper is speculative and simply suggests what most physicists have suspected for 50 years, which is that the big bang singularity in classical GR is probably a feature that we should not believe in when we get beyond the Planck scale.
Is my impression right?
