Peter J. Leithart notices Lee Smolin’s The Trouble With Physics: The Rise of String Theory, The Fall of a Science, and What Comes Next
And string theory has achieved this dominance without experimental confirmation. Smolin says that if string theory turns out to be right, “string theorists will turn out to be the greatest heroes in the history of science.” But if they are wrong and all those dimensions and symmetries don’t exist, “then we will count string theorists among science’s greatest failures” (xvii). Physicists have worked out an unfortunate “premature consensus” and “despite the absence of experimental support and precise formulation” some believe in string theory “with a certainty that seems emotional rather than rational” (xx). As a result, physics has stagnated.
