Answers to your 3 questions.
If there are no faster-than-light (FTL) influences, then
your interpretation address the EPR paradox (
http://en.wikipedia.org/wiki/EPR_paradox )? As a previously
mentioned, according to Bell's theorem, there is only one
solution to the paradox that does not involve FTL
that is Everett's theory of many-worlds.
Huw Price's time symmetry also solves the paradox.
Is this the same as, or related to Cramer's transactional
No, it's a lot simpler. It doesn't add any new physics, and removes one
What is that assumption that is removed?
That simple quantum events have a built in arrow of time. This assumption isn't in the
physics, but it's usually in the minds of people when they try to explain EPR, for
example, by saying that certain things can't happen "without FTL signalling". Saying
this assumes that the particles involved are constrained by what happened to them in the
past, but not constrained by what will happen to them in the future. This is a very
powerful assumption, built into our nature as macroscopic creatures who are
(unfortunately) all too susceptible to the effects of the entropy gradient - but there
is no reason it should apply to, for example, individual photons. Assuming that photons
act like people as far as the arrow of time goes skews our ideas of what is "reasonable
behaviour" for quantum systems, and (according to Prof Price and others) leads us to see
lots of things as weird / spooky when they are actually merely exhibiting the time
symmetry inherent in the laws of physics.
If we allow past /and/ future constraints to affect particles, for example, any need for
FTL effects to explain EPR vanishes, because all the information involved is carried by
the particles themselves, which of course never travel FTL. It just happens to be
carried in both time directions, with the photon's state in mid-flight affected by both
the event that generated it in the past and the measurement that will be applied to it
in the future.
Right. This is the same as the idea put forward by Vic Stenger in "Timeless Reality" and
Elizur and Dolev in the paper I cited. Information travels both ways along a particle
worldline - which is consistent with the time symmetry of the equations.
