Given how simple the two-body problem is, it's surprising how challenging the three-body problem is

I've implemented the simulation in 15-618, but didn't include collision between bodies. What if we need to consider the collision between the bodies? I feel like I need to do multiple pass of computation to solve the chained collisions in one time frame.. But that would be serial and extremely expensive..

@Bananya Yes, collision takes things to another level. There's been a lot of thinking about data structures and algorithms when you have many collisions happening at nearly the same time; here's one thoughtful and interesting approach.
