Reality The world is real, and we can understand the nature of that reality. Causality Events in the universe follow the law of cause and effect.
Every event has a preceeding cause.
For example, a electron with negative charge is attracted by a proton with opposite charge and moves toward it. It doesn't move without a reason. Unity Nature is unified in two major ways. First, the forces between objects follows the same laws of physics whether the objects are large as galaxies or small as atomic nuclei. Second, the design and structure of atoms is the same everywhere in the universe.
