I really don’t understand the topic much but this veritasium video is quite eye opening and goes into further depth than any layman explanation I’ve ever seen in the topic: [VIDEO]

Aside: Veritasium had a great video similar to this on the paths that light takes. I'll link to the part where they do the best physics demo I have ever seen : [VIDEO]

[VIDEO] I had learned about the double slit experiment in school, but in my mind it was something of a theoretical construct. This veritasium video demonstrates, that quantum waves are very real and tangible. This is how physics should be.
