The physics of the small, at the scale of atomic and nuclear phenomena, is described by quantum theory. We now have broadly successful quantum theories that describe three of the four observed fundamental forces in nature: electromagnetic, weak and strong nuclear interactions. On the other hand, physics on large scales, encompassing the study of solar systems, galaxies and cosmology as a whole, is described by a gravitational theory, the most successful of which is Einstein's theory of general relativity. This theory envisions gravity as a curvature of the geometry of space and time, welded together as one entity: spacetime.

在原子和核现象的尺度上，微观物理学是由量子理论描述的。我们现在已经有了广泛成功的量子理论，描述了自然界中四种观察到的基本力中的三种：电磁力、弱相互作用和强相互作用。另一方面，大尺度物理学，包括对太阳系、星系和宇宙学的研究，是由引力理论描述的，其中最成功的是爱因斯坦的广义相对论。这个理论把引力想象成时空几何的曲率，焊接在一起成为一个实体：时空。
