{wiki=T-symmetry}
T-symmetry, or time reversal symmetry, is a concept in physics that refers to the invariance of the laws of physics under the reversal of the direction of time. In other words, a physical process is said to exhibit T-symmetry if the fundamental equations governing the dynamics of the system remain unchanged when the time variable is replaced by its negative (\\(t \\rightarrow -t\\)).
