I'm not a physics person (just an interested layperson) and have read that quantum particles don't have any location until they are measured. First, is this true? And, if so, what does that mean? For example, if you don't know where a particle exists, then how can you even measure it? And what does it mean they don't normally have location? If not, how do you know they even exist at all?
