- Worth noticing
- The simulation exposes transverse velocity, dynamical-friction strength, tracer count, and speeds up to 200 million years per second.
Field notes
The interface exposes both presentation settings and model inputs, separating visual changes from gravity and trajectory recomputation. Its default Milky Way–Andromeda view reports a 2.51-million-light-year separation and a 109.3-km/s closing speed, while alternate tracer counts trade mobile friendliness against detail. Shared links preserve settings and camera state, although framing can vary with screen shape.
