# Why Do Video Diffusion Models Violate Physics? Unveiling the Flaws in Attention Mechanisms > Source: > Published: 2026-09-22 03:00:18+00:00 Despite impressive visual quality, state-of-the-art video diffusion models often generate content that violates real-world physical laws. While existing solutions rely on external priors or specialized data, we investigate the root cause by exploring the internal mechanisms of these models. Specific
