	If a [[deterministic]] process is time reversible, then the time-reversed process satisfies the same dynamical equations as the original process (see [[reversible dynamics]]); in other words, the equations are invariant or symmetric under a change in the sign of time. [[Classical mechanics]] and [[optics]] are both time-reversible. Modern physics is not quite time-reversible; instead it exhibits a broader symmetry, [[CPT symmetry]].{{fact\|date=December 2013}}

	Time reversibility generally occurs when, within a process, it can be broken up into sub-processes which undo the effects of each other. For example, in [[phylogenetics]], a time-reversible nucleotide substitution model such as the [[Substitution model#GTR: Generalised time reversible\|generalised time reversible]] model has the total overall rate into a certain nucleotide equal to ~~the total rate out of that same nucleotide.~~

	[[Time Reversal Signal Processing\|Time Reversal]], specifically in the field of [[acoustics]], is a process by which the linearity of sound waves is used to reverse a received signal; this signal is then re-emitted and a temporal compression occurs, resulting in a reverse of the initial excitation waveform being played at the initial source. Mathias Fink is credited with proving Acoustic Time Reversal by experiment.

	~~==Stochastic processes==~~
	A formal definition of time-reversibility is stated by Tong<ref>Tong(1990), Section 4.4</ref> in the context of time-series. In general, a [[Gaussian process]] is time-reversible.
