2 (eyebrows) unforgettable reminiscences are (eyes) arising displays of (mouth) authentic past.
3 (mouth) objective assumptions are (eyebrows) evident projections of (eyes) predictable future.

According to ratio of light and movement with hexagrams of the canon of changes and physiognomic symbols of facial emotions, and also according to ratio of lighting waves and dynamics of movement with space and time it is possible to make a number of cognitive conclusions.
If light does not die away and keeps primary optical parameters then will have infinite extension in cosmic space, and can be seen when there will be no stars which were sources of lighting waves. Actually light can be considered as a stream of information which does not disappear, but moves and extends in spatial scopes of universe.
