Symmetry and Time 

There is no problem of “the arrow of time”. There simply is no arrow of time, as if time could go one “way” rather than another. That metaphor is an unfortunate result of spatializing time. The picture of time as a line along which one might travel in one direction or the other is a conceptual disaster. Time is becoming. Becoming is change. The undoing of a change is also a change. There is no “unbecoming”.
