Is it true that positrons run down the time, and electrons run up the time?
The short answer is no they don't. The idea that positrons
go one way in time and electrons go the other way, comes from a
physicist named Richard Feynman. He said that a positron going forward in
time looks like
an electron going backward in time.
Diagrams called "Feynman diagrams" are used by physicists
to help them explain what particles do. The graphic on this page
is an example of one. In this kind of diagram, we can draw what
looks like a particle
going backwards in time. But this does not mean that it actually does!
No one has ever observed any particle actually travelling backwards in
