OpenAI Solves Navier-Stokes Millennium Problem
So we've been running our internal model on the Millennium Prize problems, more or less as a stress test. Tuesday morning, I got a message from the system saying it had a proof of the Navier-Stokes existence and smoothness problem, along with a Lean formalization. I'll be honest, I didn't believe it until I checked the work myself. This is the question that's been sitting there for ninety years: can a perfectly smooth, incompressible fluid in three dimensions develop a singularity in finite time? Not a discontinuity, not a shockwave, but a point where the velocity or vorticity becomes infinite? The continuum approximation of fluid motion breaks down at that point, and suddenly all the PDEs we've been using to model everything from airplane wings to ocean currents stop making physical sense. The proof is surprisingly elegant. Start with fluid at rest, apply a smooth force that stays bounded, and watch what happens. The system showed that under certain condit...
