I am reading Quantum Enigma on chapter 9 they do an experiment with 2 box if we open both box at same time we get an interference pastern of marble getting out and hitting the wall. If we open only 1 box at a time the marble hit the wall and no interference pastern is found because the act of opening 1 box create the fact of the marble being inside 1 box or in the other box. My question is what happen if I put detector inside both box that record where the marble but that recorded information stay in the box, then If I open both box at the same time will I get an interference pastern or not ? 9 I would think no since the detector have observed where the marble was ? Even if nobody as consciously checked the data ? So would not it mean that consciousness as nothing to do with the result only observation matter ? Unless someone say my detector have consciousness ? What happen if i destroy my detector data after opening the box ? What happen if i destroy my detector data before opening the box ?
