Gravity Simulation Upgrade | Update 33
Aug 16th
If Update 33 does not download automatically, follow these update instructions. If you don’t own Universe Sandbox, you can buy it via our website.
Gravity Simulation
We’ve completely overhauled our gravity simulation to increase accuracy, stability, and overall performance. Run simulations at higher speeds than ever before while maintaining gravitational accuracy.
Many simulations can now be run at noticeably higher simulation speeds. Try increasing the simulation speed of the Solar System simulation or your own custom simulation.
Before
After
The Hubble Space Telescope used to crash into or fly away from Earth at simulation speeds greater than a couple days per second. Now it maintains a stable orbit at much higher simulation speeds.
Choreography simulations, where moons are distributed evenly over a pre-computed path creating a unique design, are much more stable and create the desired patterns, like this fish, before becoming gravitationally unstable and falling apart, as expected.
We’ve also added more controls so you can fine-tune the balance between maximum simulation speed and gravitational accuracy. Learn more in our updated guide
Guides > Tutorials > Advanced Simulation Speed Controls
More Highlights
Small objects colliding with gas giants now create more realistic impacts with smaller, gradually growing impact areas
Object selection has been completely rewritten. It’s now much easier to select objects in crowded simulations with lots of dust clouds and fragments.

The Future of Universe Sandbox on Linux
Jul 12th
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
Jun 29th
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
Open > Core > A Tidally Heated Habitable Moon or Tidally Locked Earth
Searching for Supermassive Black Holes
On June 28, 2023, evidence for a signal generated from all supermassive black hole pairs from across the universe was announced by the North American Nanohertz Observatory for Gravitational Waves. Explore the galaxy-sized detector they used and learn how they found this evidence in our new guide
Guides > Discoveries > Searching for Supermassive Black Holes
More Highlights

Universe Sandbox Roadmap: 2023 & Beyond
Mar 31st
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.
- 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).
- 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.
- Untitled Graphics Overhaul
- 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.
- All of the Above
- 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 creating new internal tools to make developing and releasing updates of Universe Sandbox faster. These include systems to analyze your feedback and automate testing for bugs and issues.
- Testing 1, 2, 3
- Creating tests that run automatically to check our collision physics, simulation performance, and more will help us catch issues before they’re released. These tests record data and images we can use to find bugs more easily.
- Tracking Feedback
- Your in-game feedback and issue reports help us improve Universe Sandbox, and there’s a lot to review. We’re transitioning to a new system to sort and analyze your feedback more efficiently.
- Building the Sandbox
- We’ve revamped our automated build system. This system creates a new version of Universe Sandbox in the cloud every time a change is made by one of our team members.
- This automation saves each of us 10-15 minutes each time we want to review a change.
- With a single button, we can also release new updates to all digital stores that sell Universe Sandbox. This process used to take many hours and involved dozens of manual steps, so this makes it possible to release more updates faster.
- This new system easily makes versions of Universe Sandbox we can test on phones and tablets (iOS and Android) too.
- We’ve revamped our automated build system. This system creates a new version of Universe Sandbox in the cloud every time a change is made by one of our team members.
- New Trailer
- We’re producing a new Universe Sandbox trailer fabricated entirely in-game. We’ll be able to capture it with a single button press, making it easier to iterate on the trailer over time to show off the latest features and improvements.
- You will be able to play this new trailer inside Universe Sandbox, breaking out of it to experiment or explore every shot and simulation.
And Beyond
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.
- Gamepad Support
- 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.
- Life Simulation
- 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!
A Comet, an Asteroid, and a Planet Walk into the Solar System | Update 32.2
Mar 23rd
If Update 32.2 does not download automatically, follow these update instructions. If you don’t own Universe Sandbox, you can buy it via our website.
Watch a green comet pass by Earth for the first time in 50,000 years, see an asteroid swing by Earth in one of the closest ever encounters, and explore a hypothetical planet from the 1800s disproven by Einstein’s theory of relativity. Speaking of comets, asteroids, and planets…
A comet, an asteroid, and a hypothetical planet walk into the Solar System. The hypothetical planet says to the comet, “Why so green?” The comet says, “It’s the radiation from the Sun evaporating the carbon on my surface. You’d know that if you were as close to the Sun as people thought you were.” The hypothetical planet turns red with anger and ceases to exist. The asteroid says, “Phew, that was a close one!”
A Green Comet
The green comet, C/2022 E3 (ZTF), recently passed by the Earth for the first time in 50,000 years. Explore its path and watch this once-in-a-lifetime event occur over and over with our new simulation
The Green Comet C/2022 E3 (ZTF) in 2023
Close Encounters of the Asteroid Kind
Asteroid 2023 BU performed a close pass of Earth (though it posed no threat), only 2,200 km from the surface. That’s just under half the length of the United States! Watch one of the closest asteroid encounters ever recorded in our new simulation
Asteroid 2023 BU Close Encounter in 2023
The Non-Existent Planet
In the 1800s, many astronomers thought there was a planet, dubbed Vulcan, between Mercury and the Sun. Mercury’s orbit was observed to wobble slightly more than predicted, and Vulcan was hypothesized to explain this. We now know Vulcan does not exist, and general relativity causes the additional wobble, but you can see Vulcan’s proposed orbit in the new simulation
Hypothetical Planet Vulcan
More Highlights
Landing (press “c”) on the surface of a planet now always points you toward the horizon. Taking off returns you to your previous position instead of in front of the planet.
On February 3, 2023, astronomers announced the discovery of 12 more moons orbiting Jupiter. Learn about these new moons in our new simulation

Skies of Blue, Red Collisions Too | Update 32.1
Dec 14th
If Update 32.1 does not download automatically, follow these update instructions. If you don’t own Universe Sandbox, you can buy it via our website.
Collision shockwaves and atmosphere colors are more realistic, camera motion is smoother, and you can try the new Automatic Simulation Speed, which adjusts the simulation speed based on what’s happening in the simulation. Never miss a collision again!
Improved Shockwaves
Energy from collisions spreads more realistically over the surface of an object, resulting in larger shockwaves. Heating from collisions is also less concentrated and spreads over a larger area. Previously, shockwave expansion ended abruptly in a smaller area, often resulting in blue-hot impact sites.
The dwarf planet Ceres colliding with Earth
The Moon colliding with the Earth
Automatic Simulation Speed
Allow the simulation speed to adjust itself automatically based on various conditions, like nearby objects and collisions, by turning on the new Automatic Simulation Speed feature. Automatically speeding up and slowing down the simulation speed provides an improved viewing experience for collisions, orbits, explosions, and more.
This feature is still in active development and is currently off by default. Turn it on under
Settings > General > Experience > Auto Simulation Speed
The simulation speed will slow down to show collisions that you might otherwise miss
Create a more cinematic experience while watching simulations like Earth & 100 colliding moons
Rayleigh Scattering
Object atmospheres now visually simulate Rayleigh scattering, which describes how light scatters in the atmosphere. Rayleigh scattering is what makes Earth’s daytime sky appear blue and the setting Sun appear red. Adjust the strength of the scattering under
Visuals > Atmosphere > Rayleigh Scattering Strength
Earth with realistic Rayleigh scattering
Custom object with Rayleigh scattering at 85% strength
More Highlights
Your view now smoothly rotates, or pans, to focus on an object instead of sliding the view left or right, like a camera on rails
Atmospheres are now visible from the surface of planets. Land on a planet by pressing “c” on your keyboard to check it out.

If Update 31.4 does not download automatically, follow these update instructions, or buy Universe Sandbox via our website.
“Space is big. You just won’t believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it’s a long way down the road to the chemist’s, but that’s just peanuts to space.”
- Douglas Adams, The Hitchhiker’s Guide to the Galaxy
