Did OpenAI solve the wrong Navier-Stokes problem?

Automated excerpt

The “it” here is an external force such as gravity that affects how a fluid moves. “All fluids we know of are under some kind of external force,” says mathematician Diego Córdoba. “So to have the force makes complete sense. ”When most experts think about the Navier-Stokes problem, though, it’s without this force. OpenAI’s method can never work, in fact, without using a very contrived equation for the force that is unlike anything that could occur in the real world.
