The moment I saw the headline in New Scientist, ‘Double-slit effect seen over time too’, it struck me that this was a hugely important discovery, a pivotal moment in an ongoing paradigm shift, and an indicator of a bigger idea whose time (sic) is coming, or has come. I have no idea why. It’s like some part of me knew this already and has been waiting for it to be found. Very rarely do I perceive something so strongly as a Sign (of the Times, ha ha).
PhysicsWeb has the full story of the experiment. I have to take them at their word on its validity, ie that there is no chance it’s just a spatial effect after all (given that it’s a moving pulse, I’m not sure how this can be ruled out).
The result should be totally unsurprising, given that we are all familiar with the concept of spacetime. Perhaps it’s just that we have to overcome the deeply ingrained “feeling” that time is different to space.
