Is parallel universe exist? If yes than where & how many?

Answer 1

I think it is only a theory that has yet to be proven.

Answer 2

Parallel universes are only conjecture (as stated elsewhere). The idea of deconvergence - a spinoff idea of quantum mechanics - doesn't require time travel. It is based on the fact that quanta exist in all possible forms until they are fixed by observation. (Google Schroedinger's cat). In the macro-universe, if there are two or more possible outcomes of any event, ALL happen. If, for instance, I decide not to have breakfast this morning, there is a branching (deconvergence) of the universe and a new parallel universe is created in which I DO eat breakfast. And there are multiple universes created in which I have every possible choice of breakfast food.

Apply this idea to every particle of matter and every photon in existence for the last 20 or so billion years. Conjecturally, the number of branch points, and therefore the number of parallel universes would be nearly infinite... and growing all the time.

By definition, however, we can never detect or prove the existence of such a universe because it is 'parallel'. After branching, it never touches our universe again. So it makes a nice theme for science fiction: universes where Moses ran away from the burning bush, where Alexander never contracted syphillus and Hilter was either assasinated or won WWII. But that's all.

Answer 3

Um, to my knowledge, no one has left our universe to visit another one, so for the moment, it's just a theory and a bunch of equations. The number of alternate universes could be infinite, and I'd say a goodly percentage of them can't be considered parallel any more, because they would have diverged greatly from ours (imagine what the English language would be like if the English won at the Battle of Hastings in 1066 and didn't have French imposed on them for 100 years or so, or if Einstein had never been born, or if Julius Caesar has decided the whole empire thing was a bad idea and joined the Senate instead)

Answer 4

As for how many Para. Univ.s there MIGHT HYPOTETICALLY exist....well, difine 'exist'. Without defining that, one might answer your querry with 'none' or 'an infinite sum'.

On hypothetical ideas relating to deconvergence....well, imagine in a Para. Univ., that some nutcase went back in time and killed Mary (The Holy Mother) and Jesus was never born. And what if the Nazi regime gripped the entire globe from 1941 unto this very moment?

Also, image what life would be like right this moment if, say, a warrior from 24985A.D. went back into the year 8476B.C.-wearing some awesome armor like Ironman's-and blew away every great nation's leader and military force then simply vanished...

Answer 5

physics answer: if a parallel universe or other universes exist they are outside the realm of experience possible in THIS universe. therefore nothing can be scientifically determined about them. essentially, even if you say yes (which is dubious, because it's a yes to something nobody has ever had any experience of, nor can ever have experience of) then you still can't say where and how many. essentially, the border of our universe is a null point we can't see beyond, so we can't know anything about objects which exist outside of our universe.

Answer 6

Yes, there may be an existence on a larger matter that we observe only in terms of cosmic rays. Our galaxy might be a single star system in this context with some of the larger stars as planets.

On the smaller scale, meson matter may coexist with us and be undetectable.

Answer 7

If there was an answer...you could Google it.

Otherwise, you will be getting alot of ideas on that question.
