In theoretical physics, negative mass is a hypothetical concept of matter whose mass is of opposite sign to the mass of normal matter. Such matter would violate one or more energy conditions and show some strange properties, stemming from the ambiguity as to whether attraction should refer to force or the oppositely oriented acceleration for negative mass. It is used in certain speculative theories, such as on the construction of wormholes. The closest known real representative of such exotic matter is a region of pseudo-negative pressure density produced by the Casimir effect.

Famous quotes containing the words negative and/or mass:
“Isolation in creative work is an onerous thing. Better to have negative criticism than nothing at all.”
—Anton Pavlovich Chekhov (1860–1904)
“If mass communications blend together harmoniously, and often unnoticeably, art, politics, religion, and philosophy with commercials, they bring these realms of culture to their common denominator—the commodity form. The music of the soul is also the music of salesmanship. Exchange value, not truth value, counts.”
—Herbert Marcuse (1898–1979)
