Hi Everyone I have four questions about the nature of quantum superposition and wave functions: 1. If a particle is quantumly superpositioned in more than one location then as soon as the slightest evidence of the particle's existence in one of the locations is detected by a "measurement", does this mean that all traces of the particle's existence in any of the other locations must disappear? 2. Is it remotely possible that, under certain circumstances, a quantumly superpositioned particle can simultaneously interact with other particles in multiple locations as if it is simultaneously at all of those locations? (I can understand that one objection to this scenario might be that it violates the conservation of energy. Well, as I see it, this would not be the case if the particle is only devoting a fraction of its energies to each location.) 3. As well as collapsing, can wave functions "uncollapse"? 4. I have a hunch (which might be wrong) that it may be better to think of wave functions as continuously evolving in response to particle interactions as opposed to fully "collapsing" and/or "uncollapsing". Might there be some element of truth in my hunch? Thank you very much.
