User blog comment:Cokedragon/Why the "Multiverse" is Broken in Ben 10/@comment-3441048-20140521022902

Yozah. First off that is the most reading I have done of this wiki in a while aside from long messages from admins in stuff. Secondly, love a good time travel/universe/multiverse/interdimensional/etc discussion. I'd say I'm completely certified to explain all this out and then put in a simple way that everyone should be able to understand.

Right so you're main concern seems to be how universes can exist out of our universe. Naturally the universe is everything as you've said before but from our perspective only. Don't just picture Ben 10 which seems to be limiting your sight on this but um... Cartoon Network for example. The Channel consists of multiple TV series including and not limiting to Ben 10, Dexter's Lab, Adventure Time, PPG, Samurai Jack, Johnny Bravo, etc. You get the point. The way I see it is that those different shows are different universes aside from each other. Like Paradox said in The Forge of Creation where the other universe had their physics all over the place. In another universe, its like saying its nothing like the other. I mean sure they have the same construct like a city and people and stuff but I don't even want to begin discussing about how another universe is different from a dimension. You have to remember that the Multiverse contains multiple universes, hence the name, so it doesn't actually seem that off that there IS another universe outside of the Canon one. The BTFF Multiverse is, in fact, correct seeing how the different series' and etc on the wiki are different universes (unless they share the same universe as another series) in the Multiverse also known as Ben 10 Fan Fiction Wiki. The Forge of Creation is nearly just a place that exists outside of our universe so I wouldn't question it to a point of if it applies to our known rules of universal sciences considering that this is an animated series.

Next on the to-do list is Timelines. Timelines are, in my way of thinking, realities that exist based on the decisions you make. For example, I have an apple and a banana in front of me. Depending on what I do next to either fruit, determines the outcome of the future so if I were to eat the apple instead of the banana, the timeline is set while infinite timelines are made for an infinite amount of decisions I could have made. Okay good example, bad explanation. Obviously, you can't make an infinite amount of decisions but the decision you make triggers sereveal others and then those trigger even more and then it goes on infinitely. The fact that Gwen decided to go check on the forest instead of Ben was a decision that she could have made but didn't which created an alternate timeline known as Gwen 10. Also, just watched Ben 10,000. Speaking of which, Ben 10,000 is set in an alternate timeline as confirmed by the writers. How? you may ask. Well maybe Ben decided to act differently because of visiting himself in the future. It could create a paradox but this is more like a Multiverse discussion and not time travel. Let's just leave it as, "it created another timeline which is the main timeline and the old timeline was changed to an alternate timeline".

Next is Dimensions. Oh boy Oh boy Oh boy. Having worked with Dimensions before, I can see what your issue is here and how Ben 10 applies the manner. The Null Void and the Ledgerdomain ARE other dimensions and seems accurate considering that they don't have any physics relating to our own dimension. Dimensional Explainations are long and frustrating for the person explaining it so to put it simply: It's you just different. You may argue that but what if there was no "you" there in that dimension. That could be but a dimension is more like a copy of our universe in a space that doesn't apply to our universe but consists within it. Imagine that: A universe within a universe; Universeception. This seems like the makings of a pocket universe but those are all complicated. It actually seems more like a parral universe. But the name says it all doesn't it? A Parral Universe is a Universe Parral to our own or similar to speak into context. And even though a dimension and a Parral Universe may seem the same, remember that a Parral Universe IS in fact a Universe while a dimension is in the universe it consists within. Going back to Ben 10, Store 23 uses dimensional travel in which Ben meets his dimensional counterpart. A lot of series' do stuff like this. And considering that Ben loosing Grandpa Max in that "dimension" would affect his outcome in the future such as becoming a spoiled celebrity, you could say its an alternate timeline rather than a dimension. The only time, no pun intended, we see alternate timeline travel possible is in Back to the Future where Marty changes the outcome of his future and lives out his life in an alternate timeline. But he replaces his other self and stuff and thats not the case here. Plus everything seems blue by default unlike how in Ben's dimension, everything has its own color. I'd say its because of the other dimensions reality or whatever.

I see what you mean about our Multiverse being regconized to methods similar to those of Marvel/DC Comic Universes but besides the Earth #(insert number here) stuff I'd say its pretty accurate. We can't exactly mend the Multiverse because of some issues but crosstime? Erm... I just read up on the theory online so to correct your earlier defintion "alternate universes where history went differently". I suppose thats true given the current circumstances of Store 23 but Crosstime which seems like the method of rewriting the current timeline's past history in order to create a new reality seems to be like creating an alternate timeline (the Back to the Future type of alternate timeline).

So long story short: Universes can exist out of our universe. This is called the Mutliverse. An Omniverse contains multiple Multiverses. A Universe contains Dimensions. Dimensions are like copies of our universe but in a different image. Timelines exist within different dimensions as Time, itself, exists through space. The timeline is copied throughout multiple dimensions just like the universe in a dimension. If you want, this is an alternate timeline but don't rely on this as an answer. Crosstime is like an alternate timeline so if you chose the other answer as your answer then Crosstime is an Alternate timline which is practically another Dimension (Like I said before don't rely on this as an answer). So there you have it. Hopefully I don't have to make a long message like this again for a long while :P
