SUMMARY:Retrocausality - what would it take? - Huw Price (

DESCRIPTION:Some writers argue that retrocausality offers an a
 ttractive loophole in Bell's Theorem\, allowing an
  explanation of EPR-Bell correlations without "spo
 oky action-at-a-distance." This idea originated mo
 re than a decade before Bell's famous result\, whe
 n de Broglie's student\, Olivier Costa de Beaurega
 rd\, first proposed that retrocausality plays a ro
 le in EPR contexts. The proposal is difficult to a
 ssess\, because there has been little work on the 
 general question of what a world with retrocausali
 ty would "look like" - what kinds of consideration
 s\, if any\, would properly lead to the conclusion
  that we do live in such a world. In this talk I d
 iscuss these general issues\, with the aim of brin
 ging the more specific question as to whether quan
 tum theory implies retrocausality into sharper foc
 us than has hitherto been possible. (The talk will
  go through the central argument from my paper htt
 p://arxiv.org/abs/1002.0906 -- there is quite a bi
 t in that paper that I won't talk about\, but I'm 
 happy to discuss any of it in Q&A\, if anyone want
 s to raise it.)
