I watched this video that dumbs down and explains very simply how the quantum eraser works
From my understanding: The particle will go thru both slits if not observed (probably wave collapsed). If you setup a device that will detect it (that emits a photon if the particles passes thru) the particle will act like a particle and not a wave... But if you use a quantum eraser (by having the photon go thru a lasersplitter) the particle will once again act as a wave.
So what happens if you delay the amount of time before the photon hits a detector? Just to keep things simple, let's say you setup a bunch of mirrors so the photon took 2 seconds to hit a detector or a lasersplitters. If you then threw a particle and saw that it hit the detector in a spot that would correspond to a particle, and within the 2 seconds you added the lasersplitter, what would happen? Same question about if you did the opposite, you setup lasersplitter, saw the particle acting as a wave, and trolled the universe by removing the lasersplitter within 2 seconds?
Seems I a missing information, because I cannot see how this experiment could work (unless it can work and it can trap the universe in an infinite time loop :P )
