Take two completely disconnected observers monitoring the same system. Given the layered nature of observations, one observer (A) sees X and measures Y, but the other observer (B) sees X and W so measures Z. The current definitions I see flying around would suggest that observer A can correctly conclude that W doesn't exist because they measured Y. However, observer B can correctly conclude that W and X exist because they measured Z.
How can we suggest that time doesn't exist outside entangled entities?
Apologies for the Reddit reference, but if you could explain it like I'm 5, then I'd be grateful.
