String theory offers a possible unification of general relativity and quantum mechanics from "summary" of The Fabric of the Cosmos by Brian Greene
String theory proposes a radical rethinking of the very nature of reality, suggesting that the fundamental building blocks of the universe are not particles, but rather tiny, vibrating strings. These strings can give rise to all the particles and forces that we observe in the universe. This bold idea emerged from efforts to reconcile the two great theories of modern physics: general relativity and quantum mechanics. General relativity describes the force of gravity on a cosmic scale, explaining the behavior of planets, stars, and galaxies through the curvature of spacetime. On the other hand, quantum mechanics deals with the behavior of particles on a subatomic scale, where everything is governed by probabilities and uncertainties. These two theories have been immensely successful in their respective domains, but they clash when brought together. The challenge of unifying general relativity and quantum mechanics has long been a quest for physicists, as it holds the promise of a deeper understanding of the universe at its most fundamental level. String theory offers a potential resolution to this conflict by providing a framework that can accommodate both theories seamlessly. By replacing particles with strings, string theory is able to incorporate gravity within the framework of quantum mechanics. In this ...
