God Seeker vs Relativity Simulator

There are 7 billion people on our planet. Most of them believe in God or a higher being. But nobody has ever seen God. Is the belief in God only an illusion? Is it even worth looking for God? When the first Russian astronaut circled the Earth in his spaceship, he sparked down: «There is no God, there is no one up here!» But that seems like the wrong place to look. Nobody believes that God is floating around in space like an alien. Then where is He? Is it even reasonable to believe in something you can't see, hear or taste? For many people, religion is of great importance in their lives. Therefore, the question of whether it is reasonable to search for God is not just a superfluous, unworldly brooding. It is an exciting question that concerns us all. The God Seeker does not make any preliminary decisions, he invites us to make our own discoveries and reflections. It is divided into four areas: God, soul, world and world interpretation. If you click on a segment, further segments (questions) open up. You can «unscrew» them on a wheel. By double-clicking on a question you get a short introductory text, videos of individual philosophers and other philosophical positions appropriate to the question. You can also test your philosophical knowledge. Check your philosophical positions by means of the quiz! Which philosophers do you agree with the most? Are you more the Plato type, or do you think more like Kant, or even maybe like Wittgenstein? You might also discover a thinker you didn't know, such as Edith Stein or Alfred N. Whitehead. Expand your philosophical horizon. Whatever you decide in the end, the God Seeker will help you to give good reasons for your choice.

Relativity Simulator is an interactive relativity toolkit built strictly on the axiomatic foundations of modern physics. There is no "hard sci-fi" here — every result traces back to the Lorentz transformation of special relativity or the Einstein field equations of general relativity, and is verified against numerical truth fixtures. 【Real physics, not imagination】 · 20 interactive modules covering core effects from special relativity to black holes, gravitational waves, and curved spacetime; · Each module ships with precise charts, adjustable parameters, and a "Theory Card" with a fully visible derivation chain; · All demo numbers are recomputed locally on your device from real CODATA constants — nothing is fabricated. 【Phenomena you can verify yourself】 · Gravitational time dilation: why clocks run faster up high — ~80 ns/day faster atop Everest, ~38 µs/day faster on GPS satellites; · Twin paradox: fly to 4.22 light-years at 0.8c and the Earth twin ages 10.5 years while the traveler ages only 6.3; · Tidal disruption: why you get stretched into "spaghetti" falling into a black hole — small holes tear you outside the horizon, supermassive ones only after you cross it; · Plus light bending, gravitational lensing, the Schwarzschild horizon, frame dragging, and mass–energy equivalence E=mc². 【Built for learning and teaching】 · Volume-based progression: kinematics → gravitational field → black holes → cosmology → applications; · Bilingual (zh/en) system notes ship with every effect: derivation, physical quantities, and references; · Chinese / English UI follows your system language. 【Privacy first】 The app collects, stores, and transmits no personal data, embeds no third-party SDKs, and runs every computation locally on your device. Whether you are studying, teaching, or simply curious, Relativity Simulator lets you actually run the "invisible spacetime" and watch it.
