About

Quantum Horizon

Features
Read full description

Quantum Horizon is a cinematic observatory for relativity and quantum physics — built so you can feel spacetime, not only read about it. Fall toward a black hole and watch minutes become years. Drag masses across the Milky Way and catch Einstein rings. Prepare a wave function, then collapse it. Entangle two particles and run a real Bell test. Leave near light speed and return younger than the world that waited. WHERE SPACETIME BENDS • Black Hole Time Warp — Schwarzschild gravitational time dilation outside a horizon. Slide closer and watch Earth race ahead while your clock crawls. • Lensing Observatory — Interactive gravitational lensing across a Milky Way sky. Bend light, hunt rings, add companions that can fall into the well. • Relativistic Journey — Special relativity with live γ. Feel the twin paradox as two ages, not a textbook footnote. • You vs Others — Two ages. One voyage. See who aged less after a near-light trip. QUANTUM MEASUREMENT • Wave Function Collapse — Write two futures, set amplitudes, measure with the Born rule. One path becomes real. • Branching Histories — Parallel stories, optional relativistic aging, one collapse that chooses a history. • Entanglement Lab — Bell states (Φ± / Ψ±), Alice & Bob detector angles, running correlations, and a CHSH test that can beat the classical limit • Live quantum link — collapse and entanglement sampling can reach a real-time quantum device — so the decisive moment is tied to genuine quantum hardware. MADE TO FEEL REAL Textbook formulas power the tools: Lorentz γ, Schwarzschild dilation, thin-lens geometry, Born-rule probabilities, and Bell correlators from quantum mechanics. Beautiful, playable, and built for curious minds.
