Brian Greene Sean Carroll Fixed -

Carroll, however, has grown increasingly skeptical. In public lectures and his blog Preposterous Universe , Carroll argues that string theory has failed to make a single testable prediction in four decades. He doesn't dismiss it as wrong—he dismisses it as incomplete . Carroll prefers a more agnostic, empirical approach to fundamental physics. He has famously stated that string theory might be "post-empirical science," which is not a compliment.

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. brian greene sean carroll
