Spatiotemporal optical vortices, or STOVs (thin, gray ringlike objects), are newly described three-dimensional light structures that strongly resemble smoke rings.

Remember my past post about smoke rings:
Different, however, related concepts.
Considering that the aether is a superfluid of immense density, something moving through it will leave vortices. The concept is important, and this photonic vortex may be supporting this concept.
And light or photons, being electro-magnetic radiation is itself an othogoanl votrex of E and M radiation, which is a relativistic projection of a single field, just looks like two fields due to motion (Feynman mentions this in his reds rags, buried in there somewhere: http://www.feynmanlectures.caltech.edu/II_01.html).
As above, so below:
Nature behaves in ways not yet captured by mainstream science. They're getting closer...
