Using Universe Sandbox, users can see the effects of gravity on objects in the universe and run scale simulations of our Solar System, various galaxies or other simulations, while at the same time interacting and maintaining control over gravity, time, and other objects in the universe, such as moons, planets, asteroids, comets, and black holes.
The original Universe Sandbox was only available for Windows-based PCs, but an updated version, Universe Sandbox 2, was released for Windows, macOS, and Linux in 2017.
Universe Sandbox was designed primarily by Dan Dixon, who worked on the educational project for over fifteen years before launching the full version in May 2008.
Dixon had worked full-time on the project since 2010, founding the company Giant Army the following year. Since then, he has hired six additional designers for the company.
Simulations
Many simulations are included with Universe Sandbox, both realistic and fictional simulations:
Our Solar System, which includes the eight planets, five minor planets, 160+ moons, and hundreds of asteroids
The Andromeda & Milky Way galaxy collision, which will occur in 3.8 to 4.5 billion years
The 100 largest bodies in our Solar System
The nearest 1000 stars to our Sun
The nearest 70 galaxies to the Milky Way
A visual size comparison of the largest known stars and planets
The Apophis asteroid passing near Earth in the year 2029
The comet Shoemaker Levy 9's collision with Jupiter
2008 KV42, a trans-Neptunian object with a retrograde motion orbit
Moons converging into a single planet
The Rho Cancri (55 Cancri) system – a star with five known planets
The Pioneer and Voyager encounters with Jupiter, Saturn, Uranus, & Neptune
Visual Lagrange points of the Earth and Moon
Gamma-ray burst locations
Your own galaxy and star system
Planets out of asteroids, and stars out of planets

The team began working on a complete rewrite of Universe Sandbox in 2014. Some of the new features include atmospheres being shown on planets, dynamic and procedurally generated textures on stars and gas giants, a more realistic and graphic collision system, 3D charts in chart mode, simulation of stellar evolution, procedural detail in rings/particles, visualization of black holes, simulation of fluid-like objects (such as gas clouds, nebulae and protoplanetary disks, and planetary collisions) and much more.[4] The team demonstrated many of these features at the Unite 2012 conference.[4]
Features
Key features of Universe Sandbox as of version 2.0:[5]
Interactive n-body gravity simulator
Simple tutorial introduction
Several step-by-step activities included
All physical quantities are measured in real units: kilograms, meters, seconds, etc.
User control of the speed of time, gravity and other factors
Simulation files are editable
3D Mode for use with red and cyan 3D glasses (anaglyph stereoscopic)
Support for 3D DLP HD televisions[6][irrelevant citation]
Multiple color modes to help visualize and differentiate speeds and accelerations
Two collision modes, bounce and combine
Scaled ring systems of Saturn, Jupiter, Uranus and Neptune, and generate rings around bodies
Particle grids can be used to create 2D computer graphics or 3D computer graphics particle grids, which warps/distort the grids and causes gravitational effects by adding in moving planets or other objects (not in version 2)
"Line-up/chart" mode option shows a visual size comparison of the stars and planets
Includes the full sky panoramic view of the Milky Way from Axel Mellinger's photography of the Milky Way
Can capture high resolution screen shots
