The example of a few days ago has now spread widely (see for instance Popular Mechanics), sometimes mutating into tests of “sting theory”. Today there’s a new example out, on the middle of the front page at Scientific American: Will String Finally Be Put to the Experimental Test?
Of course the answer is “No”, this is just one more in the Swampland strain of string theory hype. This latest example is based on a paper by Bedroya and Vafa, where they make a “Transplanckian Censorship Conjecture”. The weird aspect of this kind of string theory hype is that it’s not a “test of string theory”, because it really has nothing to do with string theory. The authors of this paper are making a conjecture about “any consistent theory of quantum gravity”. If their conjecture is true we shouldn’t see the kind of B-modes in the CMB that were mistakenly claimed in the BICEP2 ...
