Clearly, there is something about the combination of quantum theory and gravity that remains unknown, and our understanding of space, time, and matter hinges on unraveling this connection. Finding a description of gravity that is compatible with our understanding of quantum physics would revolutionize cosmology, yield new insights into the first moments of our universe, and provide a deeper understanding of the theories on which all of modern physics is based.
显然，某些能够将量子理论与引力联系起来的知识我们仍然不知道，并且我们队空间、时间和物质的理解取决于这一联系。寻找一种与我们对量子物理学的理解相容的引力的描述方法将带来宇宙学革命，形成关于宇宙最初时刻的新的洞见，并提供作为所有现代物理学基础的理论的更深层次的理解。但是，尽管这一突破潜在影响无穷，并且一代又一代物理学家为此殚精竭虑，我们仍然不知道那种理论才是正确的。
