Time is a concept that is both, emergent and created. To categorise it into either one, would be to disregard it’s functionality in the role of the infinite singularities that move within it. On one hand, it is a globally recognised sequential break down of intervals in existence; while on the other, it is the fundamental concept of what constitutes our four dimensional world.
Contrary to popular belief, time does not move forward or backward. It is, in fact, the movement of the singularities within it that give it direction. This idea proposes that since time is a constant, the past and the future are actually part of the present, which is NOW!
Einstein said, “The distinction between the past, present and future is only a stubbornly persistent illusion.”
While the passage of a particular interval of time would mean something to one consciousness, it would mean something completely different to another. The same passage of time would vary once more for the consciousness created by the two entities all together. So while, time may be constant and unaltered, it certainly is tangible.
