Paging Dr. Heddle (or Some Other Physicist-Type Person)!

Thanks to a lack of posts that I feel I can competently comment on or are worth commenting on (I blame you UD and AtBC!), I was wandering down one of my favourite site, What You Ought to Know, and watched the episode, Gravity, You Failed Us.

I want to know two things:

1. Explain in layman terms - or maybe undergrad physics terms - what the big deal is with solving for a Three-Body System, and

2. Is there something to this "Electric Universe" thingy?

Feel free to discuss here,
