Part 2/10:
The focus of this discussion shifts to one of the most respected critics of string theory: Sir Roger Penrose. Known primarily for his groundbreaking work on black holes and singularities—awarded with the Nobel Prize in Physics in 2020—Penrose's criticisms are rooted in his deep mathematical background and his efforts to communicate complex ideas to the public through highly technical yet accessible science books. His 2016 book, "Fashion, Faith, and Fantasy", dedicates significant attention to string theory's shortcomings, especially in the context of the broader theoretical landscape.
