Even more "somewhat" related:

There is a physical theory that claims that all electrons are the same electron, just travelling endless through time from the beginning to the end of the universe and back (becoming positrons on the reversed timeline).

That explains why all electrons have the same exact charge.

Not sure it's a serious theory capable of proving something, but there you go.
