Held-out collision scenes still generalize in the video model

The thread says the learned motion representation generalizes beyond the training cases.
- Collisions held out in the top-right still get simulated correctly.
- That weakens the “just memorization” explanation.
- The author’s takeaway is that the model may be approximating physical law at a higher level of abstraction, not merely interpolating examples.
