Types of Parallel or Alternate Universes

[Meredith]

I know that according to quantum theory there is the potential to create a new universe with every decision we make, "do you go left or turn right?", "Do you brush your teeth or not" etc....

But all those created universes from choices would all still have the same rules of physics and conditions, I mean the light from the sun wouldn't be red and the trees blue etc....

But are there the possibility where the number of dimensions if different? Could there be a universe out there where there are four spatial dimension and two time dimensions? A universe with two spatial dimensions and fourteen time dimensions? How about one with the same number of Dimensions as ours but the Strong Nuclear force is slightly stronger or weaker and thus affecting the different types of isotopes that exist? One where gravity isn't as strong? One where the expansion of the universe is faster or slower? Does every constant in our universe mean that their could be other universes that have slight variations of those constants? Could there be Universes that have constants or forces that we lack?

Could our universe just be one in a infinite set of infinite set of Universes?

I guess it depends where those constants come from. We don't really understand their origins so we tend to think of them as being arbitrary values, when in fact they may not be.

Meredith, according to the many worlds interpretation, it's not just making a decision that creates "new universes", each time a particle's various possibilities are realized, one is created. It's continual, since the big bang. A nearly infinite number of parallel universes, each more and more different from ours the further in time one goes back, is being created in each moment in time.

It's possible that some of the early universes that "sprung" from the possibilities inherent with the events during and after the big bang might have different physics than we do. The relationships between the various forces might have turned out differently, as you said. In some, matter as we know it might not even be possible, in others there might exist totally alien forms of matter.

But like Jadzia said, it's hard to determine the full potential of those different possibilities when we're not totally certain how those forces originated in the first place. It's possible they were set in stone at the same instant the multiverse "began" and therefore all the universes have the same general physics base. We just don't know.

We don't even know if the multiverse is real, we just have some good clues that point in that direction.

I love this BTW.
