Still, Newtonian physics can get the job done for the most part. You really cant compare USE to the future that the CommonWealth & Transcendence planned for humanity-as good as the Game Engine is, Universe SandBox 1&2 arent exactly subtle.
#Universe sandbox 2 neutron star code#
It was an ancient fortran 95 program with 100,000 lines of code that took a month to run on a university supercomputer. Whats not to like Great framing, a great sample of simulation features in Universe Sandbox, and an overall. Accurate general relativity simulations require supercomputers. I did some work on an SPH simulation of Neutron Star/Black Hole mergers in college. They would start with some initial data of the shape of spacetime and then see how it evolves according to the Einstein equations, which are 10 highly non-linear partial differential equations.

Instead of simulating N number of bodies, they would be simulating a huge number of points. Universe Sandbox 2 Gameplay - Earth Vs Black Holes - Black Holes, Collisions & Supernova julieerin4873. That is, taking your simulation space, discretizing it to a hi-res 3-D grid and checking the effect that each and every point in that grid has on all neighboring points at every timestep. General relativity requires simulating the spacetime itself. Newtonian physics just requires n-body mechanics, so it is much easier to implement. However, Universe Sandbox 2 uses 300-year old Newtonian physics, rather than general relativity. If you want to simulate day-long events, like planets crashing, it might be better. Means that if you want to simulate the Solar System over a long period of time, it won't be very accurate. The slower the time, the more accurate the calculations. Its accuracy degrades as you increase the flow of time. Not sure if these kinds of questions are allowed here, but I may as well answer it.
