The experimental results indicate that only one photon is detected per one incident photon. With enough single-photon detections the interference pattern can be discerned at the detector plane. Yet EM theory suggests that the photon energy is spread across the entire interference pattern. So never mind what might be happening in other worlds, what makes all of the photon energy suddenly appear at just one detector. I certainly reject the idea that human consciousness makes all waves collapse into one. But I have a different idea that may or may not make sense. My conjecture is that the EM fields (or in general the wave functions in any particle-particle interaction) are entangled as though they are BECs. Experiments demonstrate that entangled BECs transmit information instantly between isolated but entangled BECs. If so, even if the photon energy is spread out across the entire pattern, the information of where the photon energy should go is available to the entire EM field. That does not allow you to predict where any particular photon detection will occur. But the instantaneous transfer of information may allow for a single photon detection for each transmitted photon. The alternative in single-photon experiments would be no detections at all since the EM field on any particular detector is insufficient to create a detection. If anyone buys this, I can also speculate on how wave functions could be BECs or act like them.
