Editing Antimatter (section)

==Definitions==
Antimatter particles carry the same charge as matter particles, but of opposite sign. That is, an antiproton is negatively charged and an antielectron ([[positron]]) is positively charged. Neutrons do not carry a net charge, but their constituent [[quark]]s do. Protons and neutrons have a [[baryon number]] of +1, while antiprotons and antineutrons have a baryon number of –1. Similarly, electrons have a [[lepton number]] of +1, while that of positrons is –1. When a particle and its corresponding antiparticle collide, they are both converted into energy.<ref>

 |quote=Matter conservation means conservation of baryonic number ''A'' and leptonic number ''L'', ''A'' and ''L'' being algebraic numbers. Positive ''A'' and ''L'' are associated to matter particles, negative ''A'' and ''L'' are associated to antimatter particles. All known interactions do conserve matter.

The [[French language|French]] term for "made of or pertaining to antimatter", {{wikt-lang|en|contraterrene}}, led to the initialism "C.T." and the science fiction term {{wikt-lang|en|seetee}},<ref>{{Cite encyclopedia |title=Antimatter |encyclopedia=Science Fiction Encyclopedia |url=http://www.sf-encyclopedia.com/entry/antimatter |access-date=10 October 2019 |archive-date=28 July 2019 |archive-url=https://web.archive.org/web/20190728050510/http://sf-encyclopedia.com/entry/antimatter |url-status=live }}</ref> as used in such novels as ''[[Seetee Ship]]''.<ref>{{Cite journal|last=McCaffery |first=Larry |title=An Interview with Jack Williamson |journal=Science Fiction Studies |volume=18 |issue=54 |date=July 1991 |url=https://www.depauw.edu/sfs/interviews/williamson54interview.htm |archive-url=https://web.archive.org/web/20060912123849/https://www.depauw.edu/sfs/interviews/williamson54interview.htm |archive-date=12 September 2006 |url-status=live }}</ref>
