Currently we only have 5 known states of matter: Solid Liquid Gas Plasma Bose-Einstein Condensate
It would make sense that something as unfathomable as LENR would occur as the newest & least understood state of matter. Especially when plasma might be involved, and the situation occurs in a very special case of Condensed Matter Nuclear Physics. Are there other states of matter being postulated at this point? Some of the Zero Point Energy/Vaccuum/Aether stuff might apply, but it does not hold weight in mainstream physics. It strikes me that a combination of plasma physics and BECs (i.e., the formation of sparks and a linear Luttinger Liquid formation of a BEC inside a plasma) might seal this mystery.
