There was an idea posed a bit ago known as the "one electron universe" ( https://en.wikipedia.org/wiki/One-electron_universe https://en.wikipedia.org/wiki/One-electron_universe )
> The one-electron universe postulate, proposed by theoretical physicist John Wheeler in a telephone call to Richard Feynman in the spring of 1940, is the hypothesis that all electrons and positrons are actually manifestations of a single entity moving backwards and forwards in time. According to Feynman:
> > I received a telephone call one day at the graduate college at Princeton from Professor Wheeler, in which he said, "Feynman, I know why all electrons have the same charge and the same mass" "Why?" "Because, they are all the same electron!"
> ...
> Feynman was struck by Wheeler's insight that antiparticles could be represented by reversed world lines, and credits this to Wheeler, saying in his Nobel speech:
> > I did not take the idea that all the electrons were the same one from [Wheeler] as seriously as I took the observation that positrons could simply be represented as electrons going from the future to the past in a back section of their world lines. That, I stole!
> Feynman later proposed this interpretation of the positron as an electron moving backward in time in his 1949 paper "The Theory of Positrons". ...

The idea has mathematical utility, but not any practical.
- tonymillion 4y agoMy only difference to that is that the positrons and electrons went in opposite directions on the time axis from the initial big bang event. I love the idea of a single electron being the scan line of the universe (to make an analogy to CRTs) Assume you take the normal x,y,z we “know” from reality and separate them out into 3 distinct 1 dimensional lines. Add another 1d line for time. We can see you can’t simultaneously move both “forwards” and “backwards” on any of these lines. Postulate: for time, matter (from our point of view) can only move in a singular direction from t=0 onwards (we’ll call this positive), antimatter can only move in the opposite from t=0 (negative). And, unless there is momentum in any of the spatial dimensions the particles travel on the t axis at C. I.e v=C on the t axis for matter And v=-C for antimatter. Second Postulate: the cumulative velocity of all particles must equal the speed of light Any momentum in the spatial (x,y,z) dimensions subtracts from t: explains time dilation (as an adjunct) v(t) = C-(v(x)+v(y)+v(z)) (very very simplified for this) Finally matter / antimatter annihilation is the equivalent vv, as is the case for any direct impact of two masses of equal mass and velocity. Giving us e=m(cc), in a general sense without all the pesky gravitational warping of space and time. Btw: I’m not a particle physicist (can you tell) but I did have this thought while developing code for a physics engine in a simulation game I was briefly involved in, so far I’ve not invested heavily in all the mathematics, but since I’ve just retired I might actually do so.
- akomtu 4y agoElectrons don't need to move backwards in time to become positrons. Rather, I think, that one uber-electron peacefully exists on its natural multidimensional manifold, and it's us, who declare one axis to be "time", create the dihotomy of that electron sometimes aligning with the timeline and sometimes against it. If we chose 2 coordinates as time, the same uber-electron would create a whole host of ekectron-like particles, depending on how it's aligning with the two timelike directions.
