Space is usually depicted as a static void, but Cosmic Sandbox turns that empty canvas into a playground for total destruction. You hold the power to manipulate celestial mechanics and watch how gravity shapes entire solar systems. Selecting planets and stars from the menu lets you drop them into the void to observe immediate orbital friction. Each body contains distinct layers like a core and mantle, which shatter realistically when your creations collide at high speeds. Pixels fly across the screen as you test how varying mass or rotation affects a planet's structural integrity. Stable orbits are satisfying to build, though chaotic experiments often lead to far more entertainment. Physics govern every interaction, so every motion you initiate ripples across the screen in real time. Play this physics sandbox for free in your browser right now without any downloads.
Select space objects from the panel and place them in the scene. Set their initial velocity by dragging and adjust rotation. Objects attract each other and interact through gravity. Under strong forces, they can break apart, losing pixels and revealing inner layers. Zoom and move the camera to observe the simulation. Experiment with different object combinations to create stable orbits or dynamic interactions.
Science enthusiasts and fans of digital destruction enjoy the creative freedom found here. People who like complex simulations will spend hours fine-tuning orbital paths. Those looking for a quick stress-relief session appreciate the ability to crash planets together for a chaotic, pixel-art display of cosmic physics.
Cosmic Sandbox focuses on the immediate simulation of physics, so current progress resets when you refresh the page.
You can run Cosmic Sandbox smoothly on most modern browsers, including mobile devices, as it is optimized for web play.
Place a star first, then add planets at a distance and provide them with a lateral velocity drag to achieve a stable orbit.
