For most people, the cycle of seasons and the phases of the moon are familiar phenomena, but the simultaneous three-dimensional spatial movements behind them are difficult to imagine out of thin air. Effective cognitive tools need to compress the temporal dimension (such as the yearly cycle) and transform spatial relationships (such as the Earth's axial tilt and the lunar orbital plane) from abstract diagrams into observable, continuously moving physical dynamics. A sophisticated mechanical simulator can "freeze" or "slow down" this multi-dimensional, simultaneous process of change, allowing observers to calmly track the trajectory of each celestial body and observe the cascading effects of their positional changes (such as which side is illuminated), thus achieving a cognitive leap from "knowing the phenomenon" to "understanding the mechanism." Operating our "Three-Sphere Helix" exhibit (1350*1350*900mm) gives you a "controller" for a miniature universe. By rotating the main handle,
