One of the most fascinating thought experiments would be pretty similar to the Schrödinger's Cat example, leading to interesting questions whether
what happens is already pre-determined....or whether we deal with entangled "fuzzy" quantum realities which have multiple outcomes at the same
time.
Example:
A man is expecting an important package in the mail. He knows that seeing how long ago the sender sent it on the way, the package "could arrive any
day" at his house.
He is checking his mail every day for the package:
Monday, the package did not arrive. Tuesday, it did not arrive, Wednesday it did not arrive.
On Thursday, the package finally arrived at his house.
Point of View A)
The fact that the package arrived on Thursday was already determined earlier, there is no other reality than the fact the package would come Thursday.
From that point of view, it was "wasted" that he bothered to check on Monday, Tuesday, Wednesday etc. (Of course, he did not KNOW when the package
would arrive). But there was simply no way it would have come on Mon, Tues, Wed because the "event" of the package arriving was already
pre-determined, excluding all other alternative scenarios and making them "impossible".
Point of View B)
Since he knew the package could arrive "any day" there was a legit chance the package comes Monday, Tuesday, Wednesday etc. and each time spending
time checking the mail makes sense in his eyes.
There was NO pre-determined "reality" at what exact day the package would arrive, chances the same for each day.. It could have come Monday, Tuesday,
Wed or any other day...with the event happening on a particular day "it would become" the reality,
As long as he is unsure about the package possibly arriving or not on a specific day, there is a chance it is actually coming that day. There is no
pre-determined date/event, but instead a fuzzy reality with a likelihood that its happening on any random day.
But, let's assume the package comes on Thursday, and there was also a likelihood that it arrived any day before Thursday...come Thursday with the
package, the former valid "likelihood" of the package coming any earlier day is becoming "impossible" again - therefore changing reality afterwards.
(It cannot be that it possibly arrived eg. Monday and at the same time then arriving Thursday...at the moment it arrives it would prove the other days
"wrong"...while earlier there was the same chance for it to arrive...both valid points to look at it, but also paradox.
So....are things "already written"....or are we in some quantum universe with infinite possibilities all at the same time...and how do we influence
what possibility becomes "true"....and what happens with the possibilities which are not becoming true?
