Having seen a lot of debate here recently about the collapse of the wave
function and the Copenhagen interpretation, I wondered what people thought
of the "transactional interpretation" of QM? I came across this paper by
John Cramer (Rev Mod Phys July 1986) where he describes his interpretation.

I've only skimmed through it, but it sounds like a fun idea. Basically an
emitter sends out an "offer wave" in both time directions, and an absorber
responds by sending back a "confirmation wave" in the reverse time direction.
This process "continues to completion with satisfaction of quantum boundary
conditions at emitter and absorber loci, in analogy with a standing wave
between terminating walls". Furthermore "In the transactional interpretation
the collapse, i.e., the development of the transaction, is atemporal and thus
avoids the contradictions and inconsistencies implicit in any time-localized
SV collapse".

Personally, I don't buy it because of the requirement for things to go
backwards in time. This approach to physics seems to beg an awful lot of
questions!
