Indeed, cynics claim that there are as many grand unified theories as there are theoretical physicists attempting unification.

有人戏称，每个试图建立统一理论的物理学家都有一套自己的终极理论。

They are almost certainly out there: monopoles plays a pivotal role in the widely accepted "grand unified theories", for example.

这些单磁极几乎必然地在什么地方存在着：单磁极在“大统一理论”中起着关键性的作用。

Correlation supersedes causation, and science can advance even without coherent models, unified theories, or really any mechanistic explanation at all.

关联关系比因果关系重要，科学甚至能在没有一致模型、统一理论，甚至完全不需要任何解释的情况下进步。
