Example sentences
The idea is to store the positrons, and positrons aren't light.
In that case there'd be no need to convert back-and-forth between electrons/positrons or forward/reverse time at all.
Cell tower positrons were cached on iOS devices, and this was turned into a false controversy because sensationalism sells.
It is an interesting idea, but there are other ways, probably easier, to get the positrons.
These interactions produce pions and kaons, which decays further until you end up with a bunch of electrons/positrons, gamma rays, and muons.
For example, some radioisotopes emit positrons as part of their natural radioactive decay process.
It's really neat that electrons and positrons traveling in time just bounce of photons, that are timeless (because of the speed they have).

Everybody believes in electrons and positrons and protons and large antiprotons...
Assuming each electron is created and destroyed with different positrons, you can again explain the system in terms of a single electron that changes direction four times.
Now, because electrons/positrons interact electromagnetically in addition to through the weak force, while neutrinos interact only weakly, how they scatter and the chances to produce new particles will be different.
Outside of time?) However, the idea of positrons as electrons moving backward in time is cool, and does seem like a convenient sort of an explanation for their creation and annihilation.
Quote examples
They have measurable properties that are like properties of real particles (just like "holes" in P-type semiconductors can be measured to behave like quasi-positrons).
Wheeler suggested that some positrons could be "hidden" within protons.
CTs use essentially an X-ray beam that travels in a helical path around your body, and then use math to construct a 3D image, PET is the one where you drink an isotope, and they "catch" the positrons emitted from the radioactive material in your body.
> just like "holes" in P-type semiconductors can be measured to behave like quasi-positrons I'm sorry to ask because I should actually know this, isn't the remaining positive charge accounted to the protons in the core?
Proper noun examples
