Eternal Inflation in 3D: Pocket Universes

A volumetric 3D simulation of eternal inflation: false-vacuum bubbles nucleate throughout a comoving 3D volume, expand toward a Hubble-limited saturation radius, and collide to form domain-wall shells — orbit the camera around the growing multiverse.

This is the same eternal-inflation bubble-nucleation process as the 2D diagram, but simulated as an actual 3D comoving volume with real WebGL geometry. False-vacuum background expands exponentially while true-vacuum bubbles nucleate at random 3D points and grow toward a Hubble-limited saturation radius. One bubble is marked gold at the moment it nucleates and tracked as "our" pocket universe. Orbit the camera to watch bubbles approach and collide from any direction in the volume — where two spheres truly intersect, the simulation draws the exact 3D domain-wall ring at their intersection circle, the real geometric signature that a bubble-collision search in the cosmic microwave background is looking for.

⚙ Under the hood

Visualize bubble nucleation in a real 3D comoving volume, with collisions marked by oriented rings at the exact sphere-sphere intersections.
