Is this possible? Physics delayed choice experiment Question?

In the delayed choice experiment, Particle One would encounter either one slit or two slits after the the other particle Particle Two was already observed. Depending on whether the second particle saw the one slit or two in the future, it would change the state of the first particle in the present So... We can already freeze light in place for a minute, that technology really does exist. Maybe you could keep the frozen light in place until you know the outcome of something and depending on that outcome, use one slit at the end or two. You would be able to, in this way, communicate with your self from the 1 min past and send your past self a binary 0 or 1. Maybe you could set up multiple machines in series, where when after 1 min passes, a light flash is fired through the next machine effectively freezing light for 2 min. You could the repeat until you have got the delay just above an hour... And finally... at that point all you got to do is communicate to your past self what the winning PowerBall numbers are in binary. How feasible is this?


>> Particle One would encounter either one slit or two slits ... No, it doesn't. The particle phi-wave encounters both one and two slits. We, living in our time and universe, see only part of the phi-wave behavior. For any particular particle we pick, we see either the part that encounters one slit, or the part that encounters two slits. We can't see any information going from our future into our past. Or to put it the other way around, we can't see any information coming from our future. The reality of physics doesn't include that happening, and the equations of quantum mechanics accurately represent that reality. Try this video, starting at 4:00.


Delayed choice experiments may violate our naive expectations but the mainstream physics view is that they don't violate causality or involve time travel. I'm no expert in the field but the discussion about these experiments is usually very misleading to the layman because right from the beginning they often talk about the path of the photon and which way it went through a splitter etc. But we already know from the standard double slit expt. that you can't talk like this. We know that a wave hits the splitter and half goes one way and half goes the other and we only get a single photon when the wave permanently collapses. Light is slower in air than in a vacuum, which indicates that light is interacting with the air. But the double split expt. still works perfectly fine in air. The wave interacts with the air in the slits but this doesn't force a collapse from our point of view. This shows that "hidden measurement" doesn't permanently collapse the wave.
