I just have one question. Why do scientists think parallel universes exist? What is the evidence or theory that makes this a plausible idea?

zig or zag that is the question.
I think the idea of multiple universes explains the bizarre natural phenomenon of why outcomes of a predicted event can be actualized by viewing the event. The double slit experiment showed that light behaves like both a wave and a particle. Every possible outcome of a waveform is collapsed into a event. How can all possible outcomes collapse into one event? The answer is that all events take place and depending on which reality/universe you are in is which event takes place. So in universe #1 the light particle goes left and in universe #2 the particle goes right. etc.... The multiverse theory is just one of many to explain Quantum Mechanics. This is my simplistic take on it, other forum members probably have a much better grasp.

I agree with 1.618 here.
There are some very bizarre behaviours of matter at the quantum level. Attempts to explain these behaviours has led to a lot of speculation. Basically anything that can't be ruled out is conjectured as an explanation for what is going on.
I don't think the scientists do think that parallel universes exist or think that they don't exist it is simply a speculation about why quantum behaviour is so weird. They can't be tested (as far as I know) so they remain speculations.
There have been objections to some of the "explanations" behind QM before. Einstein, for example, objected to "spooky action at a distance". However, it turned out, decades later, that tests could be done on this speculation and he was wrong. Now we have suggestions of using this effect for computing.
Will parallel universes go through the same stages? Dammed if I know.

parallel universes
If I go back in time, and change my avatar to say - Moses, will this future remain with my present avatar? Or will there be two universes? One with a Moses avatar and another with this Jesus one.
Or, will we automatically be changed, having always remembered a Moses avatar? Yet there being one universe.

Already did.
You can't go back in time. And you don't have to. The speculation is that the other universe with the other avatar exists. When you made your avatar decision the two universes split and one had Jesus and one Mosus.
(added by edit)
Though in fact this is NOT exactly what the idea is suggesting. Unless your decision is a QM event in some way that kind of difference isn't what splits the universes. But then I guess there are QM events going on in how your think. That is part of the suggestions of R. Penrose as to why we will never get AI. (I think he's wrong btw).

Re: Already did.
Does going forward or backward in time really have anything to do with the fact that there is, at least one, parallel universe operating like a mirror image in another dimension? And, how much distance could there be between an object/person in this universe and the counterpart in the other? Is what we see here Positive, and the other universe Negative like a Photograph? Is it all Black and White, and do we only see colors only because we have Rod and Cones that can perceive different wave-lengths, while our counterparts have none? We read from Left to Right, do our Counterparts read from Right to Left, and does that mean they're all Jewish?

Re: zig or zag that is the question.
The Everret-Wheeler interpretation, commonly known as 'Mamy worlds', of quantum mechanics seems to be the one you mean. A recent experiment which has been reported and is presumbaly soon to be published has been claimed to show that both the Many Worlds and the Copenhagen interpretations are incompatible with the Quantum Formalism.

Except for the Jews and Muslims that are all Christians.

I don't really know what you meant by "fact". The thought of antimatter came to my mind, but I wasn't sure. Could you elaborate?

Multiple univewrses?
I have one big problem with this interpretation of quantum mechanics.
If we carry out the two slit experiment, and the universe splits into a left-slit universe and a right-slit universe, then after a million two-slit experiments, there will be one universe of the 2-to-the-power-1000000 universes where the electron chose the left slit every time.
To put it in more every-day terms, there has to be a universe where every penny that was ever tossed landed heads, and statistics just doesn't exist.
I don't believe it!
Mike.

Why is every penny that was every tossed landing heads against statistics? There is absolutely nothing whatsoever stopping every penny ever tossed landing heads. It is a valid statistical outcome. There could only be one universe where every penny ever tossed landed heads however, and there could be literally billions of universes where 50% of coins tossed landed heads.

Re: Multiple univewrses?
Hi Mike
To put it in more every-day terms, there has to be a universe where every penny that was ever tossed landed heads, and statistics just doesn't exist.
By simple probability, this would also have to be true for a region somewhere within a single infinite universe. Normally, I find that more people are willing to believe in an infinitely sized universe rather than an infinite number of universes, whereas I'd say that the believability (and appeals to incredulity) of each is about the same.
I don't believe it!
On the basis that something extraordinary (i.e currently outside of human comprehension) must be responsible for the workings of the universe - isn't the many worlds idea a promising candidate, given that it can be tested for (in theory at least)?

On the same basis i'd have to stop believing in quantum mechanics and relativity, they were always beyond my comprehension too! lol
