When the article states 'potentially made of exotic matter', what is the reasoning that it needs to be only 'potentially' made of exotic matter? What exactly is the ring doing in this instance that it needs unknown materials to perform it's role?
I believe there is a technical definition of exotic matter, but I can't think of right now.
You're thinking of "exotic dancer." They're pretty useless for this kind of application.

Exotic matter for this type of drive I think refers to having a negative energy density, which is unknown but theoretically possible with quantum states. What puzzles me is that if the experiment requires a form of matter that doesn't actually exist, they're not going to have much luck getting a result.
