This question already has an answer here:
Perhaps I am completely wrong, but as I understand it our observation of a system can affect the outcome. The example I remember is the double slit experiment where electrons behave as a wave at first, but when observing it behaves as a particle. The conclusion, as I remember hearing, is that observing the system is what caused the different outcomes.
Why is this that case? Couldn't it have been the camera (or whatever is used to detect/observe/etc.) that causes the difference? It just seems like there are a few potential explanations that get skipped over here.
Excuse me while I most likely butcher this experiment with an example. Say I turn on the sink and water goes from the faucet to the drain. Now when I hold a cup under the water, it no longer hits the drain, instead it is captured in the cup. My explanation, having my hand there causes the behavior.
This has bugged me since I first heard it, and I have yet to find an explanation that I can accept. Given, that may be due to my inability to comprehend some of the more complex explanations, but I would still like to figure it out.
