Normally I do my best to ignore claims to have figured out the vacuum energy problem. There’s an endless number of them, mostly looking pretty dubious, and the world is full of people much more expert on the subject than me, so it seems that my time would be better spent elsewhere. I did however just notice a new preprint making such claims, Scrutinizing the Cosmological Constant Problem and a possible resolution, by Denis Bernard and André LeClair, and am curious about it. Unlike most of such things, the authors seem to know what they are talking about, and the whole thing looks not implausible to my non-expert eye. Can an expert tell me what is wrong with this (or, alternatively, tell me and my blog readers that it’s a new good idea, or an old one that is not well known)?
Comments better be about the Bernard/LeClair paper and well-informed, or will be ruthlessly deleted.
