If anybody is familiar with quantum mechanics and/or particle-wave theory this might make sense. If you are not, then it will sound like B.S. Ok, so their is a phenomenon which occurs when you look at (literally observe) an electron. This means, measuring it or observing it in any way. When you don't look at it (read: observe, measure, quantify, etc.) it behaves and exists as a wave (for example, a sine wave). When you do look at it, it exists and behaves as a single particle or point in time/space. This is because you are observing it at any single point in time. As a wave, it can exist in more than one place at the same instant. Since you measure or observe things in only one point in space-time, you cannot possibly conceive of things existing in more than one place in time. Take a picture of a someone running, and the person in the photograph is obviously not running...the image is stationary. Same thing with video. Video is just a bunch of changing still images. An electron (depending on the freq.) moves at or near the speed of light so, in essence, it can exist as a wave (like light) and therefore be in more than one place at any given point in time, until you observe it. So, if you measure or observe what's going on in a guitar amp's vacuum tubes, what happens to their output compared with what happens to their output when you do not? How would you even go about conducting such an experiment since any sort of observation would affect the experiments outcome?
