this is where the orthodoxy worketh not;
there are no antiwaves, only waves,
whether within matter or antimatter (or
within the plenum of Pascal's vacuum,
in either region .-)

did you mean,
twice the speed of light anhialation
of an outgoing & incoming wave, or
gamma 'rays' produced by matter-antimatter anhialation?

thus:
yes, a useful fiction per convergence of a geometrical series, or
an arithmetical one. the whole field (sik) is subsumed
by the study of p-adics,
wherein "minus one" (or -1.0000... or -...00001.) is found
to be ...9999., per Hensel's lemma. (in short,
the integers have the same properties of 'decimal' periodicities,
as do the fractions, or the nth roots).

what ever happenned to Buridan's donkey,
I don't see that this really effects EPR,
one way or the other; like Schroedinger's summarily dystressed cat,
the interpretation is all Copenhagenskoolish!

thus:
oh; thought it was a product of noncommutative tautological
phasespaces.

thus:
the Peanut Gallery would stil favor a demonstration:
(i+j+k)/ii = 1;
is that the favored definition of 1?, or
of one or "of THE unit?"
