Reply to comment by scurvydog-uldum in TIL that antimatter is made with antiprotons, which are the opposite of protons, with a negative charge, antineutrons with a neutral charge and positrons, which are the opposite of electrons, with a positive charge. by Doomguy2021

Get ready for a mind-blow...

Physicist Richard Feynman successfully modeled antimatter as ordinary matter that moves backwards through time.

A lot of modern physicists disagree, but Feynman is considered the closest thing to a new Einstein as there is (other than, potentially, Hawkins.)

Look up the X and Y axes of Feynman Diagrams (space and time) and the direction of the particles they model.

It is now generally accepted that Feynman is correct about that, in the sense that reversing charge and parity is indistinguishable from reversing direction in time. It's one or the other, but there isn't really a difference.

Hmm, what if I just changed the signs on everything...
