      Can someone more knowledgeable explain this better please? I have questions:

      - if you can measure the 'optical singularities' travelling FTL, then surely 'information' is travelling FTL?

      - does it matter (i.e. violate relativity) if something is travelling faster than light speed in some medium as long as it doesn't travel faster than light in vacuum?

      Something massless and devoid of information can travel faster than light

      How can such a thing be detected? And without detection how can speed be measured?

        Not an answer, but I'm modeling it as a way to pull stability out of non stable region of space for a soliton field. The gradient the void causes allows the soliton to find a useful basin.
