Explorations in the Foundations of Quantum Gravity

尽管经过了近世纪的斗争，引力（如爱因斯坦的广义相对论所描述的）仍然与量子理论（我们最好的粒子物理学理论的框架）的原理相分离。把它们结合起来是物理学最紧迫的问题之一。通过从历史和哲学的角度探索问题的基础和各种拟议的解决方案，该项目旨在揭示为什么它如此顽固地抵制解决方案，并协助解决方案。它将描绘出量子引力的各种方法的具体特征，以期为研究人员提供一个有用的工具来导航和比较它们的优缺点。

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.
