Back From the Future

"Half my life I sacrificed
But I only came to party tonight."

"The idea was that ripples of the measurements carried out in the future could beat back to the present and combine with effects from the past, like waves combining and peaking below a boat, setting it rocking on the rough sea."

Those of you playing along at home might want to take a look at the April 2010 issue of Discover magazine. It highlights the work that Jeff Tollaksen and Yakir Aharonov have done on isolating/quantifying the effects of information from the future on the present.

If the arrow of time "may be not just an illusion but a lie," is it really so hard to believe that a mind, properly trained, can recognize subtle differences in its own states that reflect/reveal the influence of the future? Retrocausation is not a new idea (Aharonov himself has been 'pushing it for four decades'), and neither is the idea that a mind, adept at pattern recognition, might see (and exploit) the same types of correlations between past and future within itself. "This isn't airy-fairy philosophy - these are real experiments" applies to psi research as well as quantum physics.

"It is upsetting philosophically... All these experiments change the way that I relate to time, the way I experience myself." Amen, brother.

But Tollaksen manages to keep free will alive in the process - "You simply have to put it down to random error in your apparatus." "The future can only affect the present if there is room to write its influence off as a mistake." - Aharonov. I've got to think a bit more about that one...
