Greene is the foremost public evangelist for string theory. To him, it is the only game in town for a "Theory of Everything"—a unified framework that merges general relativity (gravity) with quantum mechanics. When asked about problems like the cosmological constant, Greene tends to double down on string theory’s potential.
Carroll, on the other hand, believes that the future of physics lies in the development of new theoretical frameworks that can explain the universe. He argues that we need to develop a deeper understanding of the universe, including the nature of dark matter and dark energy, and that new theories, such as loop quantum gravity and Causal Dynamical Triangulation, may provide the key to unlocking the secrets of the universe. brian greene sean carroll
