Each kind of creature, and each layer of being, has its own ability to detect motion. We can only directly perceive changes when they happen within certain intervals.
We can, if we concentrate, directly observe the earth spinning, especially at dawn and dusk when the sun is revealed or eclipsed by the rotation of the planet. Or when watching the full moon as the earth spin reveals or hides the lunar sphere. From the time the horizon touches the bottom of the full moon it takes 142 seconds for it to disappear. To actually witness it moving you need to stand motionless and be aware of all the light entering your eyes, including your peripheral vision; 180 degrees horizontally and 90 degrees vertically. The moment you focus on the moon you will no longer see it moving.
But there is no way we can perceive the movement of the planet around the sun or the motions of atoms.
We can measure the motions using scientific methods, and although we can't see them with our biological sensory capabilities, we know for an absolute fact the movements are there and nothing ever returns to the same location twice.
No cycle can ever complete itself without an element of change.
This turns out to be a critical concept and requires an understanding of closed and open systems.
From the perspective of the individual system, cycles do exist. The Earth does spin neatly on its axis and from the planetary perspective, points on earth return to the same RELATIVE position each day. We will call this a closed system cycle. A bicycle is a closed system and the tires, gears, and pedals rotate very exactly back to the same position relative to the bicycle itself. If you pump the pedals of your bike your feet will move in a cycle relative to you, always coming back to the same place.
All closed systems exist within open systems where the cycles look quite different. The points on the surface of our planet never return to the same place again relative to the intergalactic fabric of space or the relative positions with other planets and stars.
When you use a bike, a point on the tire describes an up and down sine-wave relative to a road, and never returns to the same place on the road. Your feet on the pedals are always moving forward relative to the road, and their trajectory is also a sine wave, not a circular cycle.
Open systems are both larger and smaller than closed systems. For you on the bike, the road and the clouds are open systems. The atoms flow through you, racing along their own open pathways.
Cycles of closed systems always fail to meet expectations because they are created within a network of open, non-linear, flowing systems.
