I was laying in bed last night trying to get to sleep and for some reason I was thinking about how time works (probably because of the determinism discussion with seer recently)
And I started thinking about Schrodinger's cat.
Basically you have a cat in a box along with some device that can randomly kill the cat or not. This makes the cat in superposition until someone opens the box to check, at which time the cat will be either alive or dead. But until someone checks, it is both alive and dead.
Let's say there is a poison that could be released or not released at T=1. And the box is opened at T=10. Basically when you open the box the cat will be either alive or dead, but until you open it, it is both. This is a thought experiment about particles. So just imagine it works that way in the real world and you won't smell whether the cat is alive or dead.
What I realized last night was that once you do look in the box and find out whether the cat is alive or dead, you not only fix that state when you look, but you also change the past and that was the state all along. Let's say you look and the cat is dead. Then, that means instead of the cat being both alive and dead from T=1 through T=10 it means that at T=1 the poison was released and the cat died at T=1, meaning it was actually dead the whole time. There was no superposition, because when you looked, you collapsed it all the way back to T=1. Knowing something in the future can change the past.
So, thinking that can't be right, I did a search on google to see if anything like that really happens. I searched for "Schrodinger's cat change the past" and I found this:
Can the past be changed by the FUTURE? Bizarre quantum experiment suggests time can run backwards

I think what is happening is that at T=1 two new possible universes are created, one where the cat lives and one where the cat dies. You don't know which universe you are in until you open the box. If the cat is dead then you are in the universe where the poison was released at T=1, but if you open the box and the cat is alive, then you are in the universe where the poison was not released at T=1.
