Summary
In daily life “time” has two aspects, and in physics, too. Time as coordinate describes the embedding of events into the universe. Time as consecutive order shows the difference between past and future. This difference is not found in the general laws of physics, but derives from a special fact, a former state of very low entropy; its origin is not conceivable in terms of physics. The second law of thermodynamics, which violates the symmetry of the two directions of time, is a statement about our special real world.
