DEVLOG #3 — SUPERPOSITION IS READY. Date: June 2026. Superposition: The Meissner Gap is officially ready.Built around my research on near-extremal Reissner–Nordström black holes — a project selected for ISEF — Superposition is an interactive physics experience that places players in the position of a quantum particle approaching one of the most extreme environments predicted by modern physics.Rather than presenting physics through lectures or equations alone, the experience translates advanced theoretical concepts into interactive choices and narrative-driven scenarios. Players navigate the strange region near a charged black hole where classical intuition begins to fail and quantum effects become increasingly important. Research Foundation: The project is directly inspired by my work on near-extremal Reissner–Nordström black holes and the black hole Meissner effect, where certain fields are expelled from the horizon under specific conditions.Key concepts explored throughout the experience include: Event horizons and near-horizon geometry. Surface gravity approaching zero. Quantum coherence and decoherence. Black hole thermodynamics. Information preservation and loss. Quantum state evolution in curved spacetime. What’s Inside: Superposition contains 15 unique scenarios, each designed around a different physical situation or thought experiment. Every scenario presents the player with decisions that influence their journey while simultaneously exposing them to ideas drawn from advanced physics. The result is a blend of scientific storytelling and interactive exploration.Physics LevelThe concepts are drawn from topics typically encountered in upper-level undergraduate and graduate studies:General Relativity,Quantum Mechanics,Quantum Information Theory,Black Hole Thermodynamics,Quantum Field Theory in Curved Spacetime. A core goal was making these ideas accessible without stripping the scientific depth that makes them worth exploring. Project Goal:The central question was simple:What would it be like to experience the universe from the perspective of a quantum particle approaching a black hole?This project is my attempt to answer it interactively.
