[quote=@BBeast] This is a 9-body problem we're talking about, though. 2-body is perfectly predictable, but as soon as you have so many as 3 bodies things start getting chaotic, in the technical sense. Sure, Vulamera would be able to simulate ahead for a couple trillion years without any issues and find a solution which did not involve any collisions with Galbar, but all it would take is a [i]little[/i] nudge [sub]*cough*Vestec*cough*[/sub] to potentially screw us all over in a few billion years. [/quote] Little? Vestec's playing kickball. Moons are going to FLY. He's not 'nudging' anything.
