About Gravity!

This app simulates the effects of gravity. You can fling particles at each other and watch them interact. Create solar systems and galaxies! Make a planet and fling asteroids into it! Add a black hole and watch everything get sucked in! You can adjust the size, mass, and color of the particles! Zoom in and out and look around with two fingers!
