If the space terms predominate in the expression for the interval between event-points, the interval is said to be space-like, since it is then possible to select a co-ordinate system–belonging to an observer with an admissible velocity, in which the events appear simultaneous, and therefore separated only spatially.
If, however, the interval is time-like, the events cannot be simultaneous in any co-ordinate system, but there exists a co-ordinate system in which the space terms will vanish entirely, so that the separation between events will be purely temporal, id est, occurring at the same place, but at different times.
A Canticle For Leibowitz by Walter M. Miller, Jr. (1959)
There are three things which are real: God, human folly, and laughter. Since the first two pass our comprehension, we must do what we can with the third.
To sleep, perchance to dream—ay, there’s the rub: For in that sleep of death what dreams may come, when we have shuffled off this mortal coil, must give us pause. There’s the respect that makes calamity of so long life.
No one wants to explore the darkest recesses of the soul without bringing along a light. Allow self-improvement to occur at the deepest levels by aligning the entirety of your being with your purpose, facilitated by operating in a context of lightness.
