So to Love and Be Loved in Return.

A phenomenon that will come into play in this theatre is now laid out beforehand in full detail from immemorial past to ultimate future and one investigates the whole of it at glance. The time itself loses sense as the indicator of the development of phenomena; there are particles which flow down as well as up the stream of time; the eventual creation and annihilation of pairs that may occur now and then, is no creation nor annihilation, but only a change of directions of moving particles, from past to future, or from future to past; a virtual pair.~ Yoichiro Nambu (The Use of the Proper Time in Quantum Electrodynamics, Progress of Theoretical Physics, Vol. 5, No. 1, pp. 82-94, 1950).
