Building the Ultimate Solar System

This is some fun science fictional projection from a few month ago, a super-advanced engineering project (but probably still less advanced than building a dyson sphere). Presenting: the ultimate star system!

Despite the challenges Sean Raymond, an astrophysicist from Bordeaux Observatory in France, set out to build our ultimate solar system as a computer game he called Fantasy Star System. Because he's a physicist, this solar system with 60 habitable Earth-like planets had to follow the laws of physics. So his arrangement of planets had to be both scientifically plausible in the short term, and gravitationally stable over the long term of billions of years. After all, he wanted life to be able to evolve.
