I don't think this criticism is fair. For example, the article in the section quoted below clarifies that string theory hasn't been proven experimentally, and is being investigated mathematically, here: > But string theory is difficult to understand—it lives in mathematical territory that has taken physicists and mathematicians decades to explore. Much of the theory’s structure is still uncharted, expeditions still planned and maps left to be made. Within this new realm, the main technique for navigation is through mathematical dualities—correspondences between one kind of system and another.
