Universe Sandbox ² is the long awaited sequel to the original Universe. It merges real-time gravity, climate, collision, and material interactions to reveal the beauty of our universe and the fragility of our planet.

we believe this sandbox will definitely increase the fun and promise after adding this feature. There is no change at all, so we hope to add the function of evolution, that is, stars will enter different stages over time, stars-main sequence stars-red giants-red supergiants-supernovas, and stars in different stages will give some of the surrounding stars Other planets bring different effects. As a result, hundreds of millions of years have passed. Then we put a star there and adjusted the time step faster. we originally wanted to observe the evolution of stars. This sandbox is good, but we found that it has a shortcoming.
