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?

But...what pieces of regular matter are you familiar with that can bend space time enough to enable FTL travel?
