Can an effect precede its cause? You'd think not. But some aspects of contemporary physics seem to suggest that there could be retro-causation, surprising as that seems. Huw Price discusses this idea.

Such an interesting and bizarre idea, so convincingly argued.
I thought also of John Wheelers "delayed choice experiment" - is it experimental evidence for retrograde causation? It would seem what we decide to measure determines what path(s) a photon from a distant star, split by gravitational lensing took a million years ago? But is it only applicable to quantum events?
Does the opaque box experiment really depend on your choice, or does retrograde causation only occur at the quantum level?

Is backward causation committed to 'an influence going backwards in time'?
