Michio Kaku emphasizes that general relativity and quantum mechanics, though powerful separately, present a fundamental challenge in physics: they are incompatible with each other. He states, "General relativity describes the universe on a large scale, focusing on smooth surfaces and gravitational interactions, while quantum mechanics operates on a micro-level, dealing with particles like electrons and photons that are inherently discrete. Bridging that gap is the central quest of modern physics."
Kaku introduces "string theory" as the leading contender for a unified theory that seeks to reconcile the differences between general relativity and quantum mechanics. He explains that "string theory proposes that fundamental particles are not point-like dots but rather tiny strings vibrating at different frequencies. This framework allows gravity to be incorporated naturally, thus promoting a greater understanding of the unification of forces in the universe."
