It is the negative that provides the sharp and mellow contrast for its other. All things must change, one overtakes the other, and things become absolute. The human mind, and possibly lesser beings to lesser extents, are detached from time-space. Occupying frames in the known universe. The obvious questions revolve around the individuals frame, and the largest frame. What was before the big bang? How could the universe just...start? My answer is that as everything ebbs and flows, lives and dies, that this is one iteration of the universe. Through unknowable ebbs and flows, in even multiple/infinite parallel universes.
As we are attached to our lifetime in the universes time-space, we are keepers of the past and future: from first making villages, to industrial and technological revolutions. We are pulling on the momentum of uncountable human lifetimes. All working and mastering arts, and building, and struggling, and prevailing. The future isn't tomorrow, but the speed of progress has greatly increased.
