# Thread: Chaos Theory and Parallel Universes

1. Hi all,

Firstly I am only 15 so as usual for my stupidity...
I was just wondering about parallel universes being supposedly identical.
Assuming there is such a thing as a parallel universe, I am wondering how they can be identical. Doesn't the chaos theory state that the tiniest difference become exponentially more pronounced over time?
Doesn't that mean that every universe couldn't be identical...?

Confusingly,

Barry

3. Well when I think of parallel universes in the sense you describe, I think of it in the context that there are an infinite number of universes. And when there's an infinite number of something, you will find all types of that thing. So there's a universe just like this one (we're in it)...there's a universe just like this one, except you're 16. There's a universe just like this one, except you're a girl. And so on. It seems very far fetched but that's when happens when you bring infinity into the picture.

4. There is also an infinite number of universes which havent diverged from this one YET, it is however probable that they will never diverge (assuming there will be a point which is the annialation of the universe) there is an infinite number of universes so there is also an infinite number of outcomes along different routes from a single choice

5. Where does the identical part come in so...?
That's where my main misconception is.

6. if you have two universes tavelling parralel on a path on a timeline that have not changed as in every choice that has been made has been identical in both universes, but if a choice produces different outcomes in each universe they are no longer 'identical' because the following out comes change and so on and so on

So just one photon being a planck length of to the left means it aint parallel? - who would ever know?

Anyway I am moving this to psuedo science,

8. Megabrain,

Sorry for posting it in the wrong forum. I thought physics would have been the best place.
So you are saying in a nutshell that the universes cannot be identical?
What's to say that at every choice the outcome won't be the same as in other universes...?
Basically if you have two identical and parallel lines that each come to a crossroads and they both have a choice, what is to say that they won't always make the exact same choice...?

Barry

9. Also! To rephrase my final confusing point...
What is to say that a choice will have a different outcome if the fundamental basis or reasons are identical? Or is that what a choice essentially is?

Barry

10. um, i believe i answered that in my first post "however probable that they will never diverge (assuming there will be a point which is the annialation of the universe)" It is also probable that there is an infinite number of universes that do this but not all, it can also be probable that there is an infinite number of universes that follow a different path and diverge from the mainstream path

I think that's correct, i too am also 15 so forgive me if it's a little sketchy

11. No... what I am saying is that rather than a parallel universe a mirror universe and exact copy of this one the 'anti-mold' if you like - well this is after all psuedo-science, a reflection of this one in as many dimensions as you like - hey anything goes here there's not a sod on earth knows what happened before the big bang or what goes on outside our universe [if an 'outside' exists.] - or how many dimensions there are, or how gravity works, or what an electron looks like or how a transistor works [yes that's right I did say how a transistor works] or how magnets attract ferrous materials. Be my guess, have a stab in the dark - the more we guess the more the more likely one of us might be within a few million lightyears of the truth.

Do you know we do not even know how long a piece of string actually is?
we can only define it's length in terms of our own units of length.
Now I'm off for another malt whiskey....

12. Ok that seems like a very fair answer! Thanks a lot!
You guys are great for clarifying things and explaining them.

Thanks,

Barry
