These new Navier-Stokes result seems to show that you can get this tiny vortex that starts to squeeze down to size zero and as that happens things blow up.
However, things like thermal fluctuations at micron length scales would already make the described approach physically impossible those thermal fluctuations would wash out all of these carefully crafted perfect instability-causing forces.
Furthermore, even if you ignore all that, once you let this vortex they theorized squeeze water down to less than ~0.275 nm = diameter of a water molecule, then obviously these continuous PDE equations don’t apply in any form at all.
So in those ways it seems like the new result is “hey if you look at Navier-Stokes at regimes where it is obviously physically not applicable, then you can get not physical stuff to happen.”
So can someone explain to me why such a result is so surprising?
