Putting the effect before the cause

It’s generally believed time travel into the past is impossible. Only…nobody can quite figure out why it’s impossible. So just maybe, it isn’t.

John Cramer’s experiment to see if it’s possible to detect an effect before a cause is going ahead:

University of Washington physicist (and science-fiction author) John Cramer is moving forward with his experiment in backward causality, thanks in part to tens of thousands of dollars in contributions sent in by his fans. Although Cramer emphasizes that his lab is looking at “nonlocal quantum communication” rather than backward time travel per se, the gadgetry he’s assembling could settle a controversy surrounding a seemingly faster-than-light effect that Albert Einstein thought was downright spooky.

I’ll be watching with interest. Or maybe I already have watched with interest. Whatever.
