In my previous comment I didn't mention relativity. > If you're measuring N-S electron spin, you will get 100% N spin or 100% S spin but never any E-W spin. Ok, but not arguing against it. I'm arguing that there are alternative interpretation to that event other than "reality doesn't exist until we look at it". There are other explanations like: retroactive causality, many world, informational based, etc. Basically, just read the top comment, it summarizes my thoughts on the matter.
