Special Relativity with Video Games
summary
Claim: apply causal consistency derived from special relativity to multiplayer games so inputs execute in causal order rather than strict lockstep or blind dead reckoning. Uses Node.js + WebSockets, WebRTC, WebGL, Web Audio and the gamepad API; demo is a Node WebSocket + WebGL build that visualizes world lines and shows time dilation and bullet‑time but crashes over the network and contains bugs. Targets subframe responsiveness (mentions ~15 milliseconds), requires deterministic, persistent state and forbids rigid‑body dynamics; cheating by delaying actions remains possible.
