Parallel Universe: Do Many Possibilities Dissolve?

[qudrat ullah]

if parallel universe are real... means according to schordinger equation..many possible states..then when we chose anyone state..then other options or i mean possible states would dissolve into one single option whom to chose... or remains present as a reality...?

I have no idea what you are asking, but you might be interested in the concepts of wave-function collapse and the Many-worlds interpretation which does not need them.

what does it mean?

please are you believe in paralllel universe

There is nothing in the many worlds interpretations of QM which implies a 'choice'.
Also the many worlds' interpretations are not the only interpretations, there are others which do not require many worlds.
Even those interpretations which do involve many worlds do not necessesaraly imply that actual physical realisations of alternative realities exist.
The alternative worlds can be just 'possibilities'.

when we say any electron will be in many possibile states..then it means many parallel worlds here

when we say any electron will be in many possibile states..then it means many parallel worlds here

these possibilties are in real..mark templer said..they are in real...

No. No interpretation is saying that.

Please do not make multiple posts in a row, you can edit your own posts if you want to add something.
At least for me, it is hard to read your posts.

Your question is very incoherent. Can you please rephrase?

 

[qudrat ullah]

when we say .according to quantum mechanics..there are may possibilities of any event ..until we observe.. when we observe one possibility ..then other possibilities still remains?

That's entirely interpretation dependent. In Many Worlds each possibility is a new world. But in most others an observation once done - then that's it - the others no longer are relevant.

but Mark templer says other possibilities remains present

As I said it depends on interpretation. But in the majority that's simply not true.

can you breifly explain

In QM we have the formalism and interpretations of that formalism. Everyone agrees on the formalism - its the interpretations that are debated.

For the modern view of the formalism check out:
http://www.scottaaronson.com/democritus/lec9.html

As you can see its simply an extension of probability theory. And just like in probability once an outcome occurs, eg throwing a dice, that's it, the outcome occurs and the rest are irrelevant. But there are some interpretations that say - no - each possible outcome is a separate world and what happens is simply we experience that world. Even in standard probability theory you can take that view - it would be a very weird view to take - but you can do it. The reason its taken seriously in QM is it turns out to be very beautiful and mathematically elegant - but it's not to everyone's taste - including mine.

QM interpretations mostly are arguments about the meaning of probability:
