Then, when they actually hit, the collision physics support fire balls, planetwide atmospheric destruction, bits flying off… general Michael Bay levels of chaos. Planets and stars look quite a bit better by themselves, so, when they collide, you have some nice things to look at. The improvements start with the actual look of the physical models. I’m pleased to announce that, thankfully, the collisions are actually just as satisfying to watch as they are to set up. Now, the other major part of the simulation, for me, was sending things into other things to watch the carnage. It looks cleaner, smoother, and more professional. The original is on the left, the US² on the right. Take a look at the video below this to see what I’m talking about. Orbit tracks are easier to see, the particles floating through the foreground are less obtrusive, planets look nicer, stars look amazing. The first major improvement that I noticed when I first started the program up was just how much better it looked. It wasn’t exactly amazing looking, but it was very interesting way to see what would happen if, say, you were to put a second sun at the back of the solar system (it doesn’t end well). I had no idea what I was doing, but it was fun to make things smash into other things. ![]() I spent some time with Universe Sandbox (the original) around when it was first released. It has quite a few improvements over the original, including improved physics, better animations, particle effects and collision effects. It’s been in Alpha for quite a while now, first being released to the public on August 25, 2014. It’s more of a simulation than anything, a physics sandbox on a massive scale. This is a great way to come up with an idea for a new simulation you can create, or an idea for how you can change an existing simulation to see unexpected and interesting results.Universe Sandbox ² is… not really a game at all. If you've explored the included simulations and created some custom systems and now don't know what to do, try to think of a "What if." experiment. For example, in the default Solar System simulation, increase the mass of the Sun and see how it increases its gravitational influence and pulls in the planets. Try changing a property and seeing how it affects your simulation. To view properties for any object, right-click on it, or click on it once and then click on its mini-info panel on the right side. Universe Sandbox allows viewing and editing dozens of properties for every object in a simulation. Learn more in the Add Tool tutorial: Home > Tutorials > Add Tool Next, try adding moons, rings, and asteroids. Your planet will automatically begin orbiting your star. Click in the simulation to add your star.Open the Add tool from the Tools menu in the bottom bar, and select a star.Select Home > New to load an empty simulation. Here's a simple list of steps to get you started: You can filter the list by selecting a category, such as Collisions, Explosions, Historical, Exoplanets, and Galaxies.Ĭustom simulations can be very simple or very complex, and can vary widely, but a good place to start by with creating your own star system. Go to Home > Open to browse a list of included simulations. Universe Sandbox includes hundreds of built-in simulations to explore. These will show you the basics of the interface, introduce you to various tools and settings, and give you some ideas for starting your journey of astronomical creation and destruction.
