There are no straight lines in nature. There are apparent straight lines such as a beam of light but the truth is that even light curves. Things move in sine waves of becoming and unbecoming which taken on an axis creates a helix.
The universe itself pulses like a beating heart first expanding then contracting. Time moves forward and backwards along the axis and all that is was and will be again.
There is no fixed position in time nor in space. Everything is relative to another thing in the universe. Size is meaningless. Distance is meaningless.
