Do you believe in parallel worlds?

Answer 1

Hmm...I've never discovered a parallel world, but yes, I do believe in them. Interesting question.

Merry Christmas!

Answer 2

The existence of many worlds in superposition is not accomplished by introducing some new axiom to quantum mechanics, but on the contrary by removing the axiom of the probabilistic collapse of the wave packet: All the possible consistent states of the measured system and the measuring apparatus (including the observer) are present in a real physical (not just formally mathematical, as in other interpretations) quantum superposition. (Such a superposition of consistent state combinations of different systems is called an entangled state.)

Hartle[13] showed that in Everett's relative-state theory, Born's probability law

The probability of an observable A to have the value a in a normalized state is the absolute square of the eigenvalue component of the state corresponding to the eigenvalue a:
no longer has to be considered an axiom or postulate. It can rather be derived from the other axioms of quantum mechanics. All that has to be assumed is that if the state is an eigenstate of the observable A, then the result a of the measurement is certain. This means that a second axiom of quantum mechanics can be removed. Hartle's derivation only works in a theory (like Everett's) that does not cut away ("collapse") any superposition components of the wave function. In other interpretations it is not comprehensible why the absolute square is used and not some other arbitrary, more complicated expression of the eigenvalue component say, the square root or some polynomial of its norm.

The consequence is that Everett's concept is more than just an interpretation, it's rather an alternative formulation of quantum theory requiring fewer axioms.

One might argue that postulating the existence of many worlds is some kind of axiomatic assumption, but each world is merely an element in the quantum superposition of the universal wavefunction; quantum superpositions are a common and indispensable part of all interpretations of quantum theory, as is most clearly illustrated in the path integral formulation of quantum mechanics. Everett's theory just considers it a real phenomenon in nature and applies it to macroscopic systems in the same way as it is conventionally applied to microscopic systems.

Answer 3

I believe in the possibility that they exist, though we have no proof either way so it's hard to say whether it's true or not; however, in a way our dreams could be considered a "parallel" world in which things can happen that aren't as common in the "waking world". In the world(s) our dreams take us to, we might have some skill or ability that isn't there in this one; for example, in this world I'm only a white belt in 2 styles of martial arts, whereas in the world of dreams I somehow become a 10th-degree black belt in EVERY style - different worlds where our spirits are given slightly different bodies and the chance to explore new possibilities is what I believe dreams to be.

Answer 4

I do. I believe that it s alot like that sci-fi show "Sliders".

You should look that show up on the internet some time and see if you can watch an episode.

its really good and deals with this , Especialy in the First and second season (the other seasons sucked because it was more hollywood style).

anyhow i believe that there exists many alternate earth s where history is different, from small to large.

I even have a theory of how to build somthing to travell to such, yet that is not somthing i am prepared to discuss here .

Answer 5

I think if you can get an understanding for how quantam mechanics works you can clearly see that yes, there are other paralell universes. There right in front of us, all around us, they're everywhere, they're just not seeable in the way most people would want to view them. You can't think you can just step through a portal and you're in another universe, alot of people think this about Paralell Universes and it's simply not true.

You really need to look at Paralell universes as uncertain, just like the world of quantam mechanics, where nothing is for sure, you never know what kind of answer you'll get, that's the beauty of them. If more people would learn how Quantam Mechanics works they'd have a different opinion about Paralell Universes.

Answer 6

No. My senses and intelligence tell me that there is only one me. I don't think any good would come out of there being more than one me. This is the only life I am going to live and I plan to make the best of it.

Answer 7

The concept makes good moives and novels but, no such thing exists.

Answer 8

no but i do believe in paralell parking

Answer 9

do you

Answer 10

yes...
