Thanks. However from: http://en.wikipedia.org/wiki/Annihilation 'Energy may also be released by the direct annihilation of a quark with an antiquark. The extra energy can go to the kinetic energy of the released pions, be radiated as gamma rays, or into the creation of additional quark-antiquark pairs. When the annihilating proton and antiproton are at rest relative to one another, these newly created pairs may be composed of up, down or strange quarks. The other flavors of quarks are too massive to be created in this reaction, unless the incident antiproton has kinetic energy far exceeding its rest mass, i.e. is moving close to the speed of light. The newly created quarks and antiquarks pair into mesons, producing additional pions and kaons. Reactions in which proton-antiproton annihilation produces as many as nine mesons have been observed, while production of thirteen mesons is theoretically possible. The generated mesons leave the site of the annihilation at moderate fractions of the speed of light, and decay with whatever lifetime is appropriate for their type of meson.' See also: http://van.physics.illinois.edu/qa/newquestion.php?follow=Products%20of%20particle-antiparticle%20annihilations&id=22217 It seems that even quarks can annihilate into particles such as pions which then decay into photons.

I say definitely yes. When you see two matter particles as in the electron-positron pair case, unite and transform into pure radiation, you are bound to ask the question if matter is made from radiation. Everything is made of protons, neutrons, and electrons but not sodium:) 5.0 2 votes 2 votes Rate! 5.0 /5 2 +2 mitgliedd1 and 2 others learned from this answer All matter is NOT composed of sodium.

All Matter Is Made Of Energy
Matter is made of atoms. Atomic mass unit (amu) atomic number. Electromagnetic spectrum. 1/12 the mass of a carbon-12 atom. The number of protons in the nucleus of an atom. All of the frequencies or wavelengths of electromagnetic radia. A subatomic particle that has a negative charge.
