示图统一所有物理学理论的方法称为「Theory of everything」
Gravity is a troublesome force. The theory that describes it, general relativity, assumes that space and time are smooth and continuous, whereas the underlying quantum physics that governs subatomic particles and forces is inherently discontinuous and jumpy. Gravity clashes with quantum theory so badly that nobody has come up with a convincing way to build a single theory that includes all the particles
the most popular approaches being string theory and loop quantum gravity.
物理定律的统一问题，主要是指「广义相对论」和「量子场论」的统一问题，目前主要的解释方法是「超弦理论」和「圈量子引力论」
超弦理论：
量子引力论：
