A deeper understanding of the nature of space and time was and still is one of the main driving factors for the development of physics from its very beginnings. It culminated in Einstein's theory of general relativity, stating that space-time is a dynamical object, interacting with all the matter of the universe and giving rise to the gravitational force. But in addition, we know that matter is described by quantum theory, and therefore space-time must also be quantum. The construction of a quantum theory of space-time, and by extension gravity, is one of the biggest challenges for fundamental physics today.

对空间和时间的性质的更深入的理解是，现在仍然是物理学开发的主要驱动因素之一。它最终达到了爱因斯坦的一般相对论理论，指出时空是一个动力学对象，与宇宙的所有问题相互作用并引起了引力力。但是此外，我们知道物质是由量子理论描述的，因此时空也必须是量子。构建量子时空理论，并通过扩展重力是当今基本物理学的最大挑战之一。
