I believe that QED is time-invariant, such that there's nothing in the
math that can explain why time goes one way and not the other direction.
I.e., an electron going forward in time is precisely a positron going
backward in time. To call such "absurd" or "a creator of paradoxes" is
inaccurate.
I.e., you can't measure that something has gone back in time, but you
can't measure that something has gone forward in time either.

I've seen lots of descriptions of experiments ruling out "going thru two
slits at once". The formalism, as I understand it, is that it goes thru
one slit or the other, but if you look at which slit it goes through,
you are now doing a different experiment so you get different results.
And that this is explained without any reference to "waves" or the
particle being in multiple places at once. (*Possibly* being in multiple
places at once, yes.) Of course, if you don't look, maybe it *is* in
multiple places at once, but then you didn't look, so asserting you have
the right (or only) explanation is not scientific.
