Infinite doppelgangers and quantum probabilities

Postby DarkUFO on Sat Aug 28, 2010 11:46 am

Could your identical twin be living exactly the same life as you in any number of parallel universes ?

An identical copy of you is also reading this story. This twin is the same in every way, living on an Earth and in a universe that looks exactly like our own. And there may be an infinite number of them.

In the uncertain, fuzzy world of quantum mechanics, particles do not have fixed properties until they are observed. Instead, objects that obey quantum rules exist in a "superposition" of all their possible states simultaneously.

I was reading about this yesterday, I still think there will an answer for quantum physics one day that will satisfy all these problems but it's still a long way off.

They say an infinite number of doppelgängers, or copies, performing the experiment is equivalent to one observer doing the experiment an infinite number of times. This picture ties the abstract Born rule to something concrete - the existence of multiple, identical observers; a possibility that could arise if our universe is large.


I disagree with this because time/space wouldn't be the same in every infinite time or 'universe', which would therefore mean that the experiment isn't conducted in the exactly the same circumstances each time. Same goes for when someone is viewing the state of a quantum particle; I still think there is more to discover in these type of thought experiments that is being missed at present :(

You owe the companies nothing. Less than nothing, you especially don't
owe them any courtesy. They owe you. They have re-arranged the world to
put themselves in front of you. They never asked for your permission,
don't even start asking for theirs.

Has anyone read "The Man Who Folded Himself"?
In this book, the protagonist also meets his infite selves :D

Same, I am fantastic.
Seriously, though, I don't believe this theory, seems like something I would come up with.
