Universe Sandbox

Universe Sandbox is a sandbox about space, where the player is given not a ship, but the laws of physics themselves. Here you can place planets, stars and gas giants, give them speed and mass, and then watch as gravity forces them into bizarre orbits or sends them towards disaster. One click and the system falls apart. The project is also valued for its entertainment value: collisions of bodies look like real cataclysms, and the destruction of the planet into fragments can be watched for hours. It is especially interesting to test hypotheses: what will happen if the Sun becomes twice as heavy, how the Moon will behave without the Earth, whether it will be possible to retain the rings of the gas giant. The controls are simple, and the prompts explain how to set the parameters, so you don't have to be an astronomer. The set includes ready-made scenarios: Solar system, exotic stars, galactic collisions. You can upload your own, and then save and show to others. Separately, it is worth noting that the project has a training mode and physics tips: they explain what an orbit is, tidal forces and why a satellite falls on the planet. There are also tools for observation - you can fly up to an object and examine its surface up close. For those who love space, this is both entertainment and a way to understand how everything works. This is not a game with goals and victories, but a tool for the curious. For those who love space and physics, the Universe Sandbox provides a rare opportunity to feel the scale of what is happening on the scale of real calculations, and not drawn pictures.
