Gravity simulation environment. Accurate enough for demonstration and educational purposes.Has options to show gravitational systems in 2 presentation modes:- simple Euclidean 3D space- 2+1D space where X and Y dimensions are Euclidean while Z represents gravitational potentialDISCLAMER!!!This product is in no way shape or form intended to be used for scientifically accurate predictions of real-life space events! For this purpose, go to credible space research institutions. They have way better mathematicians and physicists then author of this product and way better computers then you respected user.
