I've been looking up a lot of information about quantum mechanics, and something that I keep running into are people on youtube videos/documentaries claiming that the outcome of double slit experiment changes when we measure it because we measure it, i.e. our actions of measuring it are the ones causing a different outcome.
Is this just people passing the most obvious answer/their opinion as facts, or is this an actual problem with quantum mechanics but we don't know how to make sure ?
I know people on the internet will always try to be smarter than they are, but I've never seen anyone even try to bring any arguments to this.
Thanks.
