Could the Firefly Universe Exist?

The Firefly universe, known as The Verse, features a complex star system with five main stars and six proto stars. However, astrophysically, such a system is unlikely to exist due to the instability of multi-star systems. Real-life star systems, like the Caster Star system, have specific hierarchical structures that maintain stability, unlike the Firefly system. The presence of proto stars and brown dwarfs in The Verse is also improbable, as forming such objects requires specific conditions not present in multi-star systems. Additionally, the gravitational chaos in such systems makes planet formation rare. Despite its fictional appeal, the Firefly universe's star system is highly improbable in reality.
