Relativity Lab is a professional educational app designed to help students, teachers and science enthusiasts explore the ideas of Einstein’s relativity and modern cosmology through structured learning, interactive simulations and visual explanations. The app covers special relativity, general relativity, GPS clock correction, gravitational waves, black holes, famous experiments, physics dictionary support, guided learning routes, classroom teaching tools and a full Cosmology Institute. FEATURES Einstein Academy Follow a structured learning pathway covering key concepts in relativity, spacetime, time dilation, gravity and modern physics. Interactive Relativity Lab Use visual simulations to explore abstract physics ideas in a clearer and more practical way. GPS Relativity Learn why satellite navigation needs relativistic correction and how tiny timing differences matter in real engineering. Solar System Relativity Compare relativistic effects across different objects and gravitational environments. Black Hole Explorer Explore event horizons, photon spheres, strong gravity and key black-hole concepts using educational visual tools. Gravitational Waves Understand inspiral, merger and ringdown stages, and learn how spacetime ripples connect to Einstein’s theory. Famous Experiments Review major experimental evidence including the 1919 eclipse test, Mercury’s perihelion, GPS verification and gravitational wave detection. Physics Dictionary Search and review important terms in English, Traditional Chinese and Simplified Chinese. Cosmology Institute Explore the Big Bang, Hubble’s Law, redshift, dark matter, dark energy, cosmic microwave background, observatory missions, research tools, visual simulations and guided learning paths. Teacher and Classroom Mode Use lesson planning tools, student activity sheets, discussion prompts and assessment rubrics for classroom-style learning. Portfolio and Mastery Tools Complete quizzes, revision cards, learning portfolios, milestone summaries, screenshot planners and certificate preparation tools. Relativity Lab is designed for educational use. It uses simplified models and visualisations to support understanding. It is not intended to replace formal scientific analysis, professional research software or official academic instruction.
