Universe Sandbox

Well, you finally have become the God of the cosmos that you dreamed of being all your childhood. If you suddenly thought, while reading a book on astronomy, that it would be good if there were two Jupiters, I hasten to make you happy. All your genius plans can be realized in this coolest virtual simulator, in which the objects of our solar system become toys for you. By changing their size you can trigger the apocalypse. Make collisions between the Sun and different planets, or bring your own ideas to life.
