A field you can explore
Warm trajectories move outward; cool trajectories move inward. Luminous trails connect their recorded positions. The radial view gives each distinct trajectory its own angle, with its measured radius and flow. Switch to Spatial positions to see the original x/y coordinates. Both views use a stable scale.
Pause anywhere, drag the timeline, change the color view, or zoom into the center. Replay uses the same computed states.
What is being calculated
The existing 131,072-particle central-gravity toy model, with its original outward initial flow and update equations. This experiment is separate from the seed derivations in the research audit.
Computation and display
One 900-step trajectory is computed in a background worker, then the worker stops. The initial state contains 65 distinct position-and-velocity states, repeated across 131,072 entries. Each distinct trajectory is drawn once, with its recent recorded path. The radius covers those distinct states; mean radial flow is weighted by their multiplicities. Playback interpolates between recorded states six model steps apart and uses three GPU draws per frame. Light intensity is a display choice, not a density measurement.
Preparing the measured run…
The display window ends at step 900. This is a viewing limit, not a physical endpoint. No automatic restart or camera rescaling is used.
