AI Claims a Navier–Stokes Singularity: What It Means for Fluid Physics
According to a Nature news report, OpenAI claims its most advanced AI model proved that the Navier–Stokes equations produce a 'singularity' in some instances, predicting physically impossible infinite speeds; the report situates that claim by reviewing the equations' known limits for compressible fluids and rarefied gases, and alternative modelling routes such as the Boltzmann equation, molecular simulation, and a 'triple decker' multiscale coupling.
