'''Antimatter''' is composed of fundamental particles that have the opposite [[electric charge]] and quantum spin as those of [[matter]].

'''Antimatter''' is composed of fundamental particles that have the opposite [[electric charge]] and quantum spin as those of [[matter]].

[[Matter]], and therefore everything seen, is made out of fundamental particles of nature.  These fundamental particles are hadrons and leptons, the hadrons being further subdivided into baryons and mesons.  Hadrons include the proton and neutron and leptons include the electron, [[muon]] and tau as well as the corresponding neutrinos.  For simplicity, the overwhelming majority of matter in the universe is comprised of protons, neutrons and electrons. Antimatter is matter formed from antiparticles, which have the same mass but opposite [[charge]] and quantum spin to their corresponding particles. When antimatter is brought into contact with normal matter, both particles are destroyed, resulting in an explosion that is, in terms of mass to explosive power, the most powerful known to mankind.  

[[Matter]], and therefore everything seen, is made out of particles of nature.  These particles can be divided into fermions (matter) and bosons (responsible for forces such as electromagnetism and strong nuclear force). Fermions can be subdivided into baryons and mesons.  Hadrons include the proton and neutron and leptons include the [[electron]], [[muon]] and tau as well as the corresponding neutrinos.  For simplicity, the overwhelming majority of matter in the universe is comprised of protons, neutrons and electrons.

When antimatter is brought into contact with normal matter, both particles are destroyed, resulting in an explosion that is, in terms of mass to explosive power, the most powerful known to mankind. When two particles of the same type but one matter and one antimatter (e.g. an [[electron]] and a [[positron]]), two photons are produced. Two are produced to satisfy conservation of momentum. The total mass of the particles is converted into energy, as described by [[E=mc^2]].
