Hi,
I bought Universe Sandbox yesterday on Steam, and for the most part, I quite like it. One thing I don't get however is if I set the time fast enough, why do things orbiting always end up slingshotting past whatever it is they're orbiting? For example, if I run the solar system simulation at 60 days a step, by 2018, Mercury and Venus have already jumped out of the solar system, and are traveling into deep space. By 2046, Earth seems to have the same fate. What's going on? Are the calculations at this speed too rough and inaccurate or something?
