This demonstrates the gravity of a black hole. Drag the cat out of the center to see gravity in action. Hold the cat out longer to charge up for more powerful gravity. I'm working on simulations right now and I'm happy the way this first one turned out. If you have any suggestions, please post them in the comments! Love and favorite for more! P.S. No cats were harmed in the making of this simulator and in the simulator itself!
I got the idea for this from this game called Last Horizon. You can play it here: http://www.coolmath-games.com/0-last-horizon
