Universe Sandbox is Giant Army's physics-based space simulator that lets anyone experiment with gravity, climate, and cosmic collisions on a planetary scale. Players can smash moons into planets, rip Saturn's rings apart with a rogue star, terraform Mars by adjusting its atmosphere, or watch the solar system evolve over millions of simulated years, all computed with real physics rather than scripted outcomes. It doubles as a genuine educational tool used in classrooms to teach orbital mechanics, climate science, and stellar evolution, because every catastrophe demonstrates real principles. The sandbox supports VR for walking among the planets you destroy. Endlessly fascinating for the scientifically curious, it turns astrophysics into an interactive toy without sacrificing scientific grounding.
