## Overview

Accelerate through the Minkowski vacuum and watch the Rindler horizon turn it into a thermal bath. Exact hyperbolic worldlines x² − c²t² = (c²/a)² and null horizons x = ±ct in a Minkowski diagram, horizon-split vacuum pairs becoming real Unruh quanta, an Unruh–DeWitt detector clicking with a Planck spectrum at T_U = ℏa/(2πck_B) ≈ 4×10⁻²⁰ K per g, and a live log-log Unruh vs Hawking comparison where surface gravity κ replaces acceleration a. Multi-language support (zh, en, de, fr, es, pt, ru).
