Hi folks - here's a link to an article that talks about John Cramer's planned new experiment that's intended to test entanglement and "retrocausality". http://seattlepi.nwsource.com/local/292378_timeguy15.html As usual with this kind of article for laymen, it's very hard to decipher the exact experimental setup that Cramer has in mind. The article also seems misleading to me in some ways. For instance, it talks about photons being "either" particles "or" waves, when I thought it was more accurate to say that photons are always waves that express themselves as particles when they strike a detector. (To put it another way, photons always "travel as waves and arrive as particles" - it's not an either/or situation.) The article also seems to imply that entanglement doesn't have much experimental evidence, whereas I thought it did. And it suggests that in general, physicists have found ways to explain away entanglement, and show no acausal signalling - this is news to me. My question is - does anyone know where I can find a more complete description of Cramer's planned experiment? Thanks!
