Universe Sandbox

Universe Sandbox: Physics-Based Space Simulator

A physics-based space simulator for desktop computers, modeling gravitational effects, collisions, climate, and more to create interactive planetary systems and galaxies.

What is Universe Sandbox?

Universe Sandbox is a desktop application that simulates space, galaxies, stars, planets and moons on a personal computer. It uses scientifically accurate models to replicate gravitational forces, orbits, climate patterns, collisions, and other astrophysical concepts in an interactive environment.

With Universe Sandbox, users can add planets, moons, asteroids, comets and more to a simulated solar systems and galaxies. The n-body simulation engine realistically calculates gravitational forces between all objects, allowing for accurate orbital paths and predictions. Users can speed up time to see planetary collisions, stellar explosions, orbital decay, and other long-term effects.

The software includes detailed models of Earth, the solar system planets, the Moon, the Sun and other stellar bodies. Climate models are available for Earth, Mars and Venus that simulate weather patterns and temperatures based on axial tilt, atmospheric density and solar exposure over time. Galaxy models allow users to generate realistic looking spiral, elliptical and irregular shaped galaxies populated with stars and solar systems.

Universe Sandbox provides an interactive educational environment to explore the laws of physics on a cosmic scale. Students can conduct simulated experiments that would be impossible, dangerous or take too long to perform in real life. It also supports modding and customization, allowing developers to create their own solar systems and physics rules.
