Launch some planets by clicking and dragging in the black area. Then watch gravity in action! Additional Controls (all in the blue panel on the right): - S/M/L/XL buttons change the next planet size (keys 1-4 also work). - 'Sun' tickbox adds/removes a large sun in the center. - 'Grid' tickbox shows/hides a grid. - 'Trails' tickbox' shows/hides trails behind planets. - 'Zoom' slider changes the zoom level. - 'Play/Pause' button pauses and resumes the simulation. - 'Reset' button clears all the planets.
I added an additional black hole and you can zoom out more now (you can go up to 0.00001 but no lower)
