Example sentences
One problem right from the start was the observed difference between the quantity of electrons and anti-electrons in the universe.
So the anti-electrons that we observe with positive charge can't be just ordinary electrons with their spins flipped.
If we could harvest and store the anti-electrons they would be very efficient at generating heat.
High voltage anti-electrons that produce power rather than consume it while we're at it.
No, electrons existed as far back as we can model, but they were accompanied by an almost equal quantity of anti-electrons (positrons).
You can't make antimatter 'inert' because it's reactivity doesn't depend upon some chemical property (arrangement of anti-electrons for example), but simply on the fact that it's antimatter.
In all of our observations of the universe there seem to be many more electrons than anti-electrons, but this concept would seem to imply that the number should be exactly equal.
Antimatter definitely exists, it is detectable, and used; e.g, PET scans use positrons (anti-electrons), and there have been experiments (only in animal models last I knew) with anti-proton radiotherapy for cancers.
Quote examples
The formalism of quantum field theory naturally includes plenty of situations where electrons and anti-electrons form "closed loops" in time.
As another idea, the quote in the link suggests that "maybe the extra anti-electrons are hiding in the protons or something".
(The corresponding laws are "lepton number conservation" and "baryon number conservation" - basically, the total number of electrons[1] minus the total number of anti-electrons[2] remains constant, and so does the total number of quarks minus antiquarks.
(I do like the idea, building on an idea arising from Wheeler's one-electron universe, that anti-electrons (in this case more than one) are screened within pion condensates ("maybe they're hiding in neutrons", vaguely), because that makes the symmetries even crazier, and particle physicists deserve that).
Proper noun examples
Anti-electrons have opposite lepton number, anti-quarks have opposite flavour charges etc.
