What would happen if the Parallel World exsist.

Well, according to string theory, there is a high possibility of another parallel world exist. So if the theory is correct. Should we go and try to connect to the parallel world? or it would become like Dual World where our personality is alter into becoming another persona. Like if an otaku in this world, in another world he would become a super rich genius kid or something.

Any thought of this....

If there were such a thing as a parallel earth, then there's a source of new resources to plunder. This is enough reason.

I don't think there is a dual world where we can visit ourselves\other people we know. Though i do believe in other parallel worlds/universes.

However those worlds/universes may have significantly different physical laws from us meaning life may exist in a completly different form, and where we cannot survive.

i think in the parallel world will apply the same law of physic. Maybe we are connected to the parallel world by something that have strong connection to our world.

Depends on how you see the concept of "Parallel Worlds".

It CAN be as simple as our world and the Bizzaro/Western-verse, or it can be as complex as the existence of an entire multiverse, with branches and sprouts creating whenever chaos and uncertainty are introduced to the system, creating sub-worlds where each possible choice was made.

Me, I don't think about it.

There are no bizzaro-worlds as far as anyone (excluding crackpots working out of their grandmother's basements) can tell. Outside of sci-fi, there isn't any reason to think they would at all exist. And most people who believe in a mulitverse made of all possible outcomes don't believe in it so... explicitly. The more common thoughts on it more have to do with measurement and something called quantum superposition. In the most basic terms I can think of to put it in: all possible outcomes exist when you aren't looking at them. As soon as you do, the most likely outcome becomes the one you observe. In an abstract sense, all outcomes exist in multitude of universes, but they aren't like parallel worlds or anything, and we can't observe them.

Although you might have been thinking of M-theory, which is generally accepted as the only way for "string theory" to hold any truth these days, I think. It's not really referred to as string theory that much anymore because the idea of strings aren't essential to it anymore. They can be seen as discs or points now as well, and in M-theory, they are actually membranes. In M-theory, there are 11 dimensions. You might have been thinking of those dimensions as alternate worlds or something. They aren't, but at a glance a person could think that.

Anyway, if you want to know about it, do some research on it, because it's not exactly an easy thing to condense for conversation with people who've never heard of it before. There are a lot of working ideas in this area currently, it's sortof Avant-garde physics that may turn out to be entirely horse shit.

Well we cannot actually say that they don't exist, but there also high probability of it not exist. The theory itself seems pretty good even it is not really complete.

Well, i'm not Einstien or anything, but M-theory and string theory is a way to combine all the force of the universe(sort of, i really not sure myself.) into one single pure energy while still follows the rule guided by the conservation of energy.

Well, i really can't say much because this field is related to the quantum physic. Quantum physic is not an easy thing to master.

Maybe in the parallel world, they use magic and mix it with science. And one thing maybe, just maybe gundam actually exist in the parallel world. I hope the other me is a gundam pilot.

Lol

Well that small changes can actually says that you are a female or male in the parallel world. The mutiverse is a huge thing to temper with... who knows you'll wake up one day and say, where the hell did my !@#@$ go to....

According to String theory there are an unlimited number of parallel worlds and dimensions, in all of which the events in that world are different to ours.

So basically an infinite about of options during your life that you didn't take did actually occur in a parallel dimension and world. eg. you didn't brush your teeth this mourning, in another parallel world you would have.

Even if parallel worlds exist, the idea of us getting to them is pretty crazy. We can't even make a good jetpack; how are we supposed to be able to cut through dimensions? Maybe in the future, or if we stumble across some new form of technology, but right now, there's no way it's going to happen.

If it were possible, I don't see any reason for me, personally, to visit the parallel worlds. I highly doubt there'd be a parallel me there or a parallel family. Governments may have reason to talk with the parallel world, but to the average person, it'd just be another world like ours. Why visit Iceland in the parallel world when you can visit it in our world?

Speaking of multiple universes . . .
Possible spoiler for Bokurano:

Wow, you want to grasp the secret of the world by teaming up with your other self. You are becoming one step closer into becoming Byakuran.

I would stay out of it, if it existed. We are separated for a reason after all. Who knows what ballence ur upsetting crossing over? Also, who knows whats waiting to kill you on the other side? Eather way, Im staying away.

I would kill my other self before he kills me. Not joking.

We don't KNOW it doesn't exist, there just isn't any substantial reason to think that such a thing, as you are describing it, does exist. It's just a thought, there is absolutely no proof or current operating theory based on any solid evidence that leads us to believe in true parallel universes.
To be entirely clear: There is currently no scientific reasoning whatsoever to support the idea of distinct and separate universes parallel to the one we exist in.
I'm sure there are some people looking into it as a concept, but it is not, at this point and time, a legitimate scientific theory of any kind.



As I said earlier, that isn't exactly what the theory holds true. It's not a series of distinct universes that physically exist in some way. It's more...conceptual. When you aren't watching a system, all possible outcomes exist, because you aren't observing it, therefor aren't measuring it, so the event it outside of your perspective reality. When you observe it, you will only be capable of observing the most probable outcome, and that would be occurring in our universe. It's more like viewing the universe we live in as the universe of the most likely outcomes. The other possibilities of the system do not exist when we are observing the most probable.


Again, there is a lot to be read on this subject; even if you just read the Wikipedia article on it, at least do a little research if you are interested in it.



Now you're just being philosophical.

We should try to connect with them to see if there some technology that can be share to make the world a better place to live.

And apply the Schrödinger's cat, cause the theory is still unproven. It's still a new theory, the existance of the parallel world is still in a box. We could assume it to exist or not.

You make a fatal mistake here friend. You should be like me and travel to all the parallel universes collecting an army of yourself to take over one universe for just you...and all your copies and I suppose copies of your friends and whatnot.
