Time Dilation Explorer Lab
Relativity Simulations by CS
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Explore Einstein's special relativity with interactive clocks, cosmic trips, bite-sized lessons, quizzes, and progress badges.
Time Dilation Explorer Lab turns special relativity into an interactive space-science lab.
Slide toward the speed of light and watch time change in real time. Compare Earth time with traveler time, explore the light-clock thought experiment, send a virtual ship toward nearby stars, and learn why Einstein's ideas matter in real science and technology.
Designed for curious learners, students, teachers, and space fans, the app explains time dilation, length contraction, the twin paradox, light speed, GPS corrections, and near-light-speed travel through visual simulations and short lessons.
Key features:
- Interactive time dilation simulator with Earth and traveler clocks
- Speed vs Time graph for comparing journeys across cosmic distances
- Light Clock demo showing why moving clocks tick slower
- Twin Paradox visualization with Earth twin and traveler twin timelines
- Length Contraction lab for seeing fast-moving objects shrink along motion
- Cosmic Journey mode with destinations from the Moon to Andromeda
- Bite-sized relativity lessons with examples, takeaways, and fun facts
- Quiz mode with categories, best scores, streaks, and hints
- Progress dashboard with lesson completion, quiz progress, and badges
- Daily relativity facts and achievement rewards
The free version includes core simulations, starter lessons, quizzes, and selected destinations. A one-time Premium unlock removes ads and opens advanced lessons, full-speed controls, expanded quiz content, extra destinations, and additional interactive tools.
Whether you are reviewing physics for school, introducing relativity in a classroom, or simply wondering what a near-light-speed journey would feel like, Time Dilation Explorer Lab helps make spacetime visible.
