exotic matter

Exotic matter refers to hypothetical materials that have unusual properties, such as negative energy density or negative mass, which are not found in ordinary matter. In physics, especially in theories about concepts like wormholes or faster-than-light travel, exotic matter is needed to stabilize these structures and keep them open. Unlike regular matter (which is made of particles like atoms), exotic matter would behave in ways that challenge our understanding of physics, and so far, it remains a theoretical concept without experimental confirmation. Its unique properties could allow for phenomena currently considered impossible within known physics frameworks.
