String theory has been the leading candidate for a theory of all fundamental interaction since 1984. The theory has attracted an incredible amount of interest, with almost 50 per cent of the entire theoretical high energy physics community working on it, and/or on topics that are inspired by it.
Unfortunately (and totally surprisingly, I must say), the theory has failed to deliver any physical predictions (that's not the first time that the community had such a rude awakening: remember when the proton refused to decay?).
Even more so, since a number of years now, there has been a growing feeling within the theoretical HE physics community that the theory may be… Read more
