SpaceFold is an interactive AR learning experience that transforms the Theory of Relativity into something you can see, explore, and understand. Instead of relying on complex equations, SpaceFold uses Augmented Reality, interactive simulations, and intelligent explanations to help users build an intuitive understanding of space, time, and motion. FEATURES โ€ข Spacetime Fabric Place a spacetime grid in your environment and watch it bend under the influence of mass. Explore gravity as the curvature of spacetime and discover how objects naturally move through curved geometry. โ€ข Time Walk Become a moving observer and experience the effects of time dilation. Compare clocks, explore motion near light speed, and understand how time changes depending on your journey. โ€ข Observer Perspective Switch between different reference frames and see how events can appear differently to different observers. Learn why simultaneity is relative and why there is no universal clock. โ€ข Intelligent Explanations Powered by Apple Foundation Models, SpaceFold provides contextual explanations based on your interactions, helping transform observations into understanding. WHY SpaceFold? Physics is often taught through equations and diagrams. SpaceFold takes a different approach by allowing users to interact directly with the concepts behind relativity through immersive AR experiences. Whether you're a student or simply curious about the universe, SpaceFold offers a visual and intuitive way to explore one of the most fascinating ideas in modern physics. Experience physics.
