A simple yes no question The more I read about this the more vague it becomes I understand almost everything but I have a simple question that I would like to be answered only by someone who is entirely sure of the answer Will there still be an interference pattern when a There are detectors but the data is destroyed before the electron arrives b The same but the data is destroyed after the electron has arrived but before anyone anything has looked at the wall I think this is a reasonable question as it is physically testable and objective The article states that a is true but several people in the discussion apparantly don t agree And the article states nothing about b but I have read other articles who make that statement I know this isn t the place to ask questions but I ve already done alot of research about this and I m lost in an endless sea of contradiction I would just like to know the answer without devoting my life to it Certainly because it s such a simple and objective yes no question Greetings
