This reminded me of a physics theory in which all electrons are actually the same electron, going back and forth in time: https://en.m.wikipedia.org/wiki/One-el

- 2bitencryption 8y agoeven if it's a crazy idea, there's something attractive about a really simple, elegant answer to a complicated question. "why are all electrons fundamentally the same"? "because they're all the same electron." (edit: oops, didn't realize I just quoted the wiki article until after I opened it)
- kolpa 8y agoIt's not a theory so much as a metaphysical interpretation -- it's scientifically equivalent to the many-electron Universe.
- jerf 8y agoIt isn't if we can't find the electrons going backwards, which we generally can't. Nowhere near enough positrons in the right places. I consider it a fun example of the sort of thing that modern physicists should be familiar with, so it's useful both historically and for didactic purposes, but as a conjecture it appears to be simply false.
- jenno 8y agoSometimes I wish I knew some in-depth physics, take a bunch of LSD, and see what hidden truths would emerge... Does that happen? A bunch of scientists should really take some psychedelics together.
- MereInterest 8y agoNo, it could be disproven. Take a high-energy gamma ray, and have it undergo pair production, creating an electron and a positron. Capture both in the same Penning trap, then let them annihilate. This would result in a loop that is disconnected from any other electrons, showing that the electron/positron in the loop is distinct from other electrons.
