Hi - brand new here, so go easy on me! :) I have been considering that the major difference between the observed and the unobserved in relation to the behaviour of light particles appears to be missing something. Every "measurement" device used in the unobserved tests relies on linear components and apparatus - nothing is convex or concave. Bringing an observation device to the experiment introduces some kind of lens (doesn't it?) - surely this introduces a convex component to the apparatus/experiment..? I have no idea how that pans out mathematically but having introduced an item of apparatus that (potentially) contains a curve must have some effect on how things are observed, rather than relying on results which, when unobserved, have no such curves(?) I expect this has been discussed previously but I can't find mention of it, so I am offering it for discussion. Thanks!
