> the NS problem is not physics and not predictive, it happens at scales smaller than molecules, so it doesn't occur in real fluids

1. How is it not physics? It's goal (as laymen me crudely understands it) is to determine if a singularity could be physically realized in a perfect liquid.

2. Why does it happen at scales smaller than molecules? Unless it requires properties that a liquid made of particles sized like real atoms cannot achieve, I don't understand.

TY.
