Exotic Matter

In physics, exotic matter is a term which refers to matter which would somehow deviate from the norm and have "exotic" properties. There are several uses of the term.

  • Hypothetical particles which have "exotic" physical properties that would violate known laws of physics, such as a particle having a negative mass.
  • Hypothetical particles which have not yet been encountered, such as exotic baryons, but whose properties would be within the realm of mainstream physics if found to exist. Futurist Ray Kurzweil has speculated that by the end of the 21st century it may be possible by using femtotechnology to create new chemical elements composed of exotic baryons that would eventually constitute a new periodic table of elements in which the elements would have completely different properties than the regular chemical elements.
  • States of matter which are not commonly encountered, such as Bose–Einstein condensates and quark–gluon plasma, but whose properties are perfectly within the realm of mainstream physics.
  • States of matter which are poorly understood, such as dark matter.

Famous quotes containing the words matter and/or exotic:

    No matter what time it is, wake me, even if it’s in the middle of a Cabinet meeting.
    Ronald Reagan (b. 1911)

    I do not approve of anything that tampers with natural ignorance. Ignorance is like a delicate exotic fruit; touch it and the bloom is gone.
    Oscar Wilde (1854–1900)
