In order to be, things must renew themselves continually, they must arise again and again. Their potential wakes up, they become active, they appear. But then they vanish again. They give up themselves — for the sake of becoming, for the sake of being.
Space is a structured space of knowledge, knowledge expresses itself as activity, it bears things — and vanishes into space anew.
Time is determined by the pulsation of the things, their waxing and waning. All things come into being every moment anew. They appear, they interact with other things. Without that they would never exist.
A thing does not appear but in its interactions. These determine its existence, its extent, its space. And its time: every interaction, every appearance of a thing, is a new moment in time.
If everything changes continually between to be and not to be, between on and off, then the idea of completely different (“parallel”, so to speak) times is anything but absurd.
The gap is not, it does not exist, it just becomes effective as a transition from one state to another. (Existence itself, the flow of time, therefore cannot be but continuous.) Observed from another time continuum that pulses in a totally different rhythm, however, a lot of time may have passed between those different states. Or several periods are wholly skipped.
The same pulsation that appears as the constant ticking of clocks defining the time in one continuum may perform in another time continuum a complex rhythmic pattern. If ever; perhaps it will never be recognizable as anything regular; maybe there is absolutely nothing.
There can be found a lot of different notions and concepts of “time”; this term is used in many ways — not necessarily always in connection with clocks.
Very often it is associated with terms like “past”, “presence”, and “future”. These may apply to a certain point at the time scale defined by clocks. But the underlying concept they refer to does not generally imply exact measuring; it is not about distinct periods of time.
Sometimes past and future are just kind of directions, seen from a certain spot, the time being, the presence, now. But in general, there is meant to exist an essential distinction, the two terms referring to completely different qualities.
There is an intimate relation to knowledge: the past is principally known (or at least knowable), while the future is generally (still) unknown.
In this sense, presence is the passage from not knowing to knowing. So knowledge is being created, at every moment. In every interaction. Through activity.
