Electron Identity and Time Travel - theory

I was wondering about the plausibility of a "joke theory" I saw in an online web comic (www.qwantz.com not sure where it is anymore though). Essentially it suggested that all electrons are the same electron except it just travels through time - explaining their being identical.

Originally I almost dismissed the idea pretty quickly. However, since reading the most recent New Scientist in which the main article said that quantum particles such as electrons and photons have no place on the arrow of time (or something like that). It seems that this theory is more plausible if not just for me.

At least in the case that the electron has "failed to kill itself" (/will fail to kill itself / is currently failing to kill itself).

 

Thanks for your views and help in advance!

I'm afraid this theory has shaky grounds on several levels. To highlight an immediate problem, imagine an interaction between two electrons which are the same electron- this isn't just hard to visualise but invalidates the notion of locality, special relativity and several conservation laws. Namely, that a particle has a definite position in space and time.

What you may have read in the new scientist is that photons are time independent to themselves. All bosons (massless particles which essentially are the quantum states of a field) are massless and so can travel at the speed of light, to them time does not exist, for they are travelling at the maximum speed limit, and so relative to everything else their travel is instantaneous to them. However, this does not mean that a photon can be everywhere at once according to us. For a two photons to hit our eyes at the same time there must have been two localised events from two different photons, to claim they were the same thing would invoke serious philosophical debate on what we actually mean by a particle.
