Universe Sandbox is described as 'Create & destroy on an unimaginable scale with a realistic physics-based space simulator. Explore the beauty of our universe and the fragility of our planet. Use science to bend the laws of gravity, collide planets, boil away oceans, fire epic space lasers, and customize your universe' and is an app in the education & reference category. There are more than 10 alternatives to Universe Sandbox for a variety of platforms, including Windows, Android, iPhone, iPad and Steam apps. The best Universe Sandbox alternative is Celestia, which is both free and Open Source. Other great apps like Universe Sandbox are Space Engine, OpenSPH, Orbiter and Solar System Simulator.
Celestia is an application for real-time 3D visualization of space, with a detailed model of the solar system, over 100,000 stars, more than 10,000 galaxies, and an extension mechanism for adding more objects.
on Universe Sandbox you can mess with planets and create your own solar system, but on Celestia you can only see planets
i dont like it because i cant make my own simulations.
Space Engine - a real-time 3D space simulator, procedural universe generator and visualiser. It lets you explore the universe in three dimensions, starting from planet Earth to the most distant galaxies.
It has realistic graphics just like Universe sandbox
its not able to use it as a sandbox
C++ SPH/N-body library and standalone GUI application, mainly designed for astrophysical simulations
Orbiter is a realistic 3D real-time space flight simulator program.
Fed up with space games that insult your intelligence and violate every law of physics? Orbiter is a simulator that gives you an idea what space flight really feels like - today and in the not so distant future.
In this app you can explore almost any moon or planet of our solar system and visit remarkable nearby stars and see their location in the Milky Way. But you can also change existing bodies or add new ones and make a solar system of your own.
Real-time planetary collision sandbox powered by SPH physics: smash planets together and watch the destruction and its aftermath!.
It is not that realistic,but they are both cool and entertaining
If you're a fan of Solar Smash, Universe Sandbox, Spaceflight Simulator, Solar System Sim; this is your new favorite game!
Experience the captivating wonders of the cosmos with Galaxy Map - Stars and Planets, an interactive 3D planetarium powered by precise data obtained from NASA and ESA space missions. Delve into a profound expedition through the infinite expanse of space, where an abundance of...
Physics sandbox game that uses a graphics card as a supercomputer. Change the laws of physics, design mechanisms, create A-Life worlds and inhabit them with living beings.
Simulation & rendering software that uses Smoothed Particle Hydrodynamics (SPH) to simulate collisions of celestial bodies, accretion disks around black holes, or formation of galaxies in the early universe.
Per its own description (our solar system) it is not a sandbox like Universe Sandbox
Pioneer is a space adventure game set in the Milky Way galaxy at the turn of the 31st century. The game is open-ended, and you are free to explore the millions of star systems in the game. You can land on planets, slingshot past gas giants, and burn yourself to a crisp flying...
