That is, if one were to construct a lightbulb out of antimatter and run positrons through it, what would happen? Would it light up?
More generally, is there such a thing as “positricity”?
Positively!
:smack: I probably should’ve seen that coming.
Seriously, though, would flowing positrons have properties similar to electricity? A Google search on “positricity” brings up very few hits, so I’m guessing there’s another word for this, if it exists at all.
But interestingly, if I understand correctly, it’d give off regular photons - there are no “anti-photons” since the photon is its own anti-particle.
Electromagnetism is symmetric if you swap matter and antimatter, so, yes, your antimatter lightbulb would light up if you passed a positron current through it. (The term “positron current” is a standard technical usage - unlike “positricity” - though thus far it’s only real life application involves positrons in a vacuum, typically in a particle accelerator - rather than in a wire.)
Things get more complicated when one considers electromagnetism as part of the electroweak force, but that complication can be ignored in thinking about how a bulb works - and hence how an antibulb would work.
Yep.
