The Future of Universe Sandbox on Linux

Our latest release, Update 32.3, will be our last with a native Linux version of Universe Sandbox. Future Linux versions of Universe Sandbox on Steam will be powered by Valve’s Proton, software built into Steam that allows Windows games to run on Linux.

If you are a Steam Linux player, no action is required to continue playing Universe Sandbox. This change should be seamless.

We know this may be disappointing, but after internal testing and user feedback, we have found that playing Universe Sandbox through Proton on Linux machines provides a better overall experience. Valve has put a tremendous amount of energy into developing Proton, which has made this decision much easier. As a small indie team, the upkeep of a Linux version was disproportionately high compared to the size of the Linux player base (just over 0.5% of all players).

Due to the limitations of the Steam platform, we can no longer provide access to older native Linux versions. If you are a Steam player who needs access to the last Linux native version (Update 32.3), please contact us.

If you are a GOG or Itch player, older releases will remain available in their respective download sections. We recommend GOG and Itch players on Linux use either Heroic Games Launcher or Lutris for future versions.

Grand Collision Unification | Update 32.3

If Update 32.3 does not download automatically, follow these update instructions. If you don’t own Universe Sandbox, you can buy it via our website.

We’ve combined our two previously separate collision methods improving collisions so shockwaves now realistically eject fragments as they spread across gas giants during collisions. Interface panels, such as graphs, data maps, and object properties, are now remembered when you open saved simulations. We’ve also added new astronomical discoveries to explore, like the galaxy-sized detector used to find new evidence of supermassive black holes.

Unified Collisions

Collisions are more realistic, with shockwaves propagating across gas giant surfaces and fragment ejection direction based on impact angle with our new unified collision system. This new collision solution combines our two previous separate collision methods.

Saving Your Interface

Pick up right where you left off with the properties panel open, or include a temperature graph in a shared simulation to show a planet heating up from a close encounter with a star. Saved simulations now remember the state of the interface panels. See it in action in

Universe Sandbox Roadmap: 2023 & Beyond

We’re working to give you more power to understand and control the complex phenomena of the universe. Our roadmap for 2023 includes simulating the lakes of liquid methane on Titan, hot planets emitting light, and realistically colliding spacecraft and bananas. But before we dive in, let’s recap some accomplishments from last year.

Highlights From 2022

In 2022, we put out 9 updates for Universe Sandbox. These included many new features, but some of our favorites are

• Spinning up planets so fast they break apart using the new Force Spin tool
• Exploring constellations for 10 different cultures
• Customizing the look and topography of planets and moons with a library of realistic color and height maps
• Fundamental improvements to our planetary collision system

Check out our 2022 Retrospective for more on what we did last year.

So What’s the Plan for 2023?

• Add more materials for constructing & simulating planets & atmospheres
• Overhaul our under-the-hood physics architecture to improve accuracy and performance
• Simulate light emission from hot planets
• Continue work on bringing Universe Sandbox to phones and tablets
• Improve our development tools to identify issues quickly and provide a more bug-free experience

Many of our projects, like bringing Universe Sandbox to phones and tablets, have been in development for months or years. While we plan to work on everything we discuss here in 2023, complications may cause features to be delayed, and our priorities may change.

More Materials & Composition Simulation

We’re expanding the number of materials in Universe Sandbox you can use to simulate, construct, and terraform planets and atmospheres realistically. For example, new materials like methane will allow us to fully simulate lakes of liquid methane on Titan. We’re also adding advanced simulation to compute planet radii based on the pressure and temperature of each material in the planet’s composition. Ever wonder how big the Moon would be if it were made entirely of oxygen? Soon you’ll be able to find out.

• A (Multi) Material World
  • Planet radii and atmospheres will be realistically simulated based on the mass and phase (solid, liquid, and gas) of each material in their composition.
  • Simulation of an atmosphere’s heating (the greenhouse effect), color, and opacity, including Venus-like atmospheres, will be based on their material composition.
  • Designing the properties, data views, and tools for you to construct atmospheres, build and terraform planets, and track these materials is a crucial part of our development process.

• Physics-based Phases
  • The phase of each material in a planet’s composition will be realistically determined based on its pressure and temperature. Make a planet entirely out of water and see the phases from the inside out (our current model says it would be 100% liquid inside).
    • Material phase models are based on geological and astrophysical measurements and research.
  • Planet radii will then be calculated based on the phase and density of each material that makes up a planet’s composition. If you change the composition, the radius will change with it.

• Tracking Materials
  • Materials will have customizable colors based on their physical properties that will blend on the surface of objects. Watch oceans of methane mix with oceans of oxygen in real time.

Physics Fundamentals

Our project to add everyday object collisions, like throwing a banana at a car, led us to first rewrite our physics architecture. Realistically smashing satellites together is part of continuous efforts to improve the realism and performance of Universe Sandbox.

• New Physics Architecture
  • Overhauling our custom N-body (gravity) simulation will improve gravity-related accuracy, stability, and performance. Tight orbits like the Hubble Space Telescope around Earth should be stable at simulation speeds as high as a month per second (instead of a few days).
  • These updates are the foundation for future physics improvements, like spaceships.
  • Everyday Object Collisions
    • Currently, when objects collide, they’re treated as spheres. We’re working on adding new physics so that everyday objects, simple shapes like dice and pyramids, but also complex shapes like sledgehammers and spacecraft, will collide according to their unique forms. This is often known as rigid body collision physics.
  • Improved Planetary Collisions
    • We’re researching methods to allow objects to stretch and deform, like two fluids mixing, during collisions, to improve upon the sphere absorbing method we currently use. Stay tuned for a status update later this year.
  • Meteors & Shooting Stars
    • To simulate meteors and shooting stars, we’re working on allowing objects to burn up while traveling through a planet’s atmosphere. We’re exploring ways of applying this drag force to objects passing through gas clouds and liquids too. Currently, atmospheres have no effect on objects as they pass through them.
  • Advanced Game Engine Features
    • As an ongoing project to optimize our simulation, we’re transitioning to the Data-Oriented Technology Stack (DOTS) from Unity, the game engine we use to build Universe Sandbox. We’re excited about the expected performance gains.

  Lights in Space

  We want to light up the universe – by allowing hot planets and moons to emit light. We’re also planning a massive graphics overhaul that will change how you see the Universe (Sandbox).

  • Light ‘em Up
    • Light – it’s not just for stars anymore. Hot planets will emit light based on their temperature so you can light up your simulation by setting Earth to 1000 °C.
    • This lighting system will eventually allow you to place and customize lights anywhere in the simulation so you can illuminate your universe without stars.
    • We don’t want to say too much yet, but we’re working on a massive update to our graphics system that the whole team is very excited about.

    Universe Sandbox on Tablets & Phones

    

    We’re stepping up our development for Universe Sandbox on mobile devices (for iOS and Android) after some delays last year. You can read about our plans in our first Mobile DevLog, and be on the lookout for more updates in the future.

    • Small Screen Experience
      • The primary obstacle in mobile development is adapting our interface that works well on a large screen to work on a small touch screen (like a phone).
      • We’re building a system to intelligently resize, hide, and reveal panels as needed. Our goal is to reduce the need for you to spend time managing the user interface so you can focus on bending the simulation to your will.
      • Universe Sandbox on mobile is built from the same codebase as the desktop version and will have the same features.
      • Performance is also critical, and we’re working to make Universe Sandbox run smoothly on mobile devices no matter the simulation.

      Enhancing Our Developer Toolkit

      We’re always thinking about the future of Universe Sandbox. Our longer-term goals include gamepad support, life simulation, and more planet customization options. These are still in early development, and we don’t have a timeline for their release (because software development is hard, and not even our astrophysicists can predict all of the complexities of simulating the universe).

      • Custom Textures
        • We want to give you more control over the appearance of your planet. Satisfy your world-building desires by creating a planet using custom maps or images, like a picture of your dog.
        • What could be better than playing Universe Sandbox from the comfort of your couch? We’re working on adding gamepad support for more ways to control your universe. This will improve our Steam Deck support and has the potential to support other gamepad-based systems in the future.
        • Our expanded materials improvement is the cornerstone of our plans for life simulation. Once Universe Sandbox includes the essentials for life, like oxygen and carbon dioxide, we will be able to explore simulating simple life that will spread across the surface of a planet.

        We’re excited for the year ahead and can’t wait to make Universe Sandbox even better!
