Time, a measured or measurable period, a continuum that lacks spatial dimensions. Time is of philosophical interest and is also the subject of mathematical and scientific investigation. Learn more about the concept of time and its history in this article
The meaning of TIME REVERSAL INVARIANCE is a principle in physics: if a given sequence of events is physically possible the same sequence in the opposite order is also possible.
