Glancing at the Sora videos, if there are two opposite light sources why only one shadow in one direction? How is a dalmatian able to walk from one window ledge to the other when both window shutters are wide open on both windows? No, I don't see a physics engine at play. uproxx.com/life/openai-...

Yeah, it's like what @raphaelmilliere.com said, I don't think it creates an actual, robust physics engine that runs everything by the laws of Newton, Maxwell, etc. It's more like that the model might learn a "physical intuition" of how different objects and phenomena play out during its training
