Explorations in the Foundations of Quantum Gravity
Despite almost a century of struggle, gravitation (as described by Einstein's general theory of relativity) remains divided from the principles of quantum theory (the framework in which our best theories of particle physics are couched). Bringing them together constitutes one of the most urgent problems of physics. By exploring the foundations of the problem, and the various proposed resolutions, from both historical and philosophical perspectives, this project aims both to shed new light on why it so stubbornly resists a solution and to assist in its solution. It will map out the specific features of the various approaches to quantum gravity with a view to offering researchers a helpful tool to navigate and compare their virtues and vices.
