Probability and infinite Universes

[Juuliuus]

Hi all, new guy here. My first post (how exciting!)...

 

Like to get an opinion about the following:

 

"Classical" quantum mechanics states that all possibilities exist until the event is observed, then all probability curves drop to 0 except for the 1 that "becomes" the event (a la schroedingers cat...The cat is dead or alive when you open the box, before that it is both dead and alive).

 

My question is: Once observed one of the possibilities has dropped to zero and the other becomes one. However, since we are in a universe that has a "history" the fact that at one point in time both possibilities existed is a fact and can't be erased...

 

Therefore, if the cat is alive, then is there not another universe, or snapshot of a universe, where the cat is dead? Or vice versa? And if so then at each instant aren't there, then, infinities of infinities of universes (or least snapshots of them) generated?

 

If true then it raises the question of where the "cursor" is that says we are here in this universe. That's it...opinions?

...after I posted a list of similar threads came up and it looks this one is already being discussed, sorry. Still if you want to say something go ahead!

Quantum theory = very small

Infinite universes = very large plus pure speculation

This thread may experience a relativistic ride.

Welcome Maybe we are the "cursor".

Methinks the cat can observe whether it is alive or dead.

...is born Relativistic Self-Cursored Infinite-Universe Theory.

 

Perhaps the cat has a box in which there is a mouse which will be alive or dead depending...

 

True so true, Mr Skeptic. Hence infinities of infinities of infinities of possible, or snap-shot universes. Multiple (infinite?) cursors observing their ways through a plethora of Universes.

 

Could anyone remind me of the "formal" definition of an observer?
