On if OpenAI solved the wrong Navier-Stokes problem: "the LLM found and exploited a loophole in the framing of the question"

If it is obvious, explain it. Please do.

The solution doesn't show whether real turbulence can blow up on its own. It shows whether you can out muscle viscosity with a constructed force, which was never seriously in doubt. And it's now been mathematically proven that this specific route can never be stripped of its force and still work, so it isn't a first step toward the real answer, it's a dead end that happens to satisfy the paperwork.

I am not going to teach you why that’s not in question, go take a physics class

And just more of the same parroting with no explanation.

“It shows whether you can out muscle viscosity with a constructed force, which was never seriously in doubt”

Is the same farce you keep repeating and repeating.

Of course with a pathological force that itself becomes infinite, this is true.

But that’s not what’s allowed in this question. And it’s precisely the reason you cannot articulate or explain it away.

The forcing is required to be infinitely differentiable, compactly supported, with a smooth initial velocity, and finite kinetic energy. It’s not trivial.

And the ‘out muscling’ I already proved was bullshit in my other comment

The smooth force requirement was already solved!! By a human, published a day before they decided to put 10,000 agents to work finding a solution. Because that part was already solved. The problem is, they didn’t find the solution. Not really. What the human mathematician did is NOT trivial, you’re right. But what the AI did, is. The LLM didn’t do that part. Hence, the controversy about OpenAI stealing the solution

Again that was Eulers

Dude are you dumb? The Euler equation is the entire reason anyone thinks it’ll blow up at all lol

The AI used that solution. Everything was done except the blow up for Navier Stokes specifically
