Fraction orbiting the same direction. Starts at 67% — two thirds prograde. Rises as retrograde bodies (which have more crossing orbits) are eliminated first.
Phases
Gas cloud — 3D orbits, star dominates
Collisions — retrograde eliminated first
Sorting — prograde direction dominant
Solar system — many bodies, aligned plane
Phase 1 — Gas Cloud
Blue bodies orbit anticlockwise (prograde — 67%). Red bodies orbit clockwise (retrograde — 33%). Retrograde bodies have higher orbital inclinations so they cross more prograde orbits and get eliminated faster. This is why real solar systems are overwhelmingly prograde.
3D Physics — Visual vs Physical Size
Bodies are drawn larger than their true physical size so they are visible on screen. All gravitational forces and merge decisions use actual physical mass — not the display size. Star mass = 500, body mass = 0.1 each — ratio matches real solar systems where the Sun holds 99.8% of all mass. Two bodies close in 2D view may be at different heights in 3D and pass safely — only bodies truly close in all three dimensions collide.
BFUT Connection
The same gravitational sorting at galactic scale: galaxies initially move in all directions. Those on crossing trajectories merge or eject. Survivors move predominantly apart — the Hubble recession — without any expansion of space.
