That too. Note that's why I specified "when you look". It's easy to tell 
whether an electron is in a particular place at a particular time when 
you look. It's called, for example "Dynamic RAM."  It's more difficult 
to tell when you're not looking.

You're mistaken. Happens all the time (on a sufficiently small scale). 
QED doesn't work if you don't take it into account. Plus, most (or all) 
of QED is time-reversable. I.e., an electron going forward in time looks 
just like a positron going backwards in time.

Indeed, given a photon travels at the speed of light, time must be 
stopped. Yet, we know events happen during the lifetime of a photon. If 
time is stopped (by Lorenz contraction), why would a photon ever 
spontaneously change into something else?

Good to know. Your opinion has been noted and filed appropriately. ;-)

Seriously, there are (reputable) people who believe electrons are 
fungible because it's all the same electron moving around in time and space.
