Hmm...I believe the term 'Dimension' is getting mistaken here.

Some people are using the term as in Alternate Realities and others are using it to describe Degrees of Freedom (Which has nothing to do with politics   ).

String theory pretty much says that an anti-matter universe is possible, especially with this crazy multiverse thing they're throwing around.

I agree with you 'anti-string theory', but you're making some pretty big claims there. Most scientific sources that are readily available are somewhat 'off'.

Antimatter Universe would mean the anhilation of our Universe. This does not seem to be happening so the best guess is it doesn't occur.

Only if that universe was put on top of ours. If there was a multiverse that was in some other dimension, we'd be fine

It does?... As it goes string theory really doesn't say much! It has evolved to a point where it said that over 10 to the 50000 possible universes, it doesnot state if these universes actually exist now or ever existed, just that there is no one unique universe that could have emerge out of the big bang.

As for being mistaken, i using the scientific and mathematical definition of "Dimension", which is very different from parallel universes ( which all can exist in the same dimesions ) or parallel Branes ( which are multidimensional structures) that would exist if an additional spacial dimension exist that would seperate our brane from them.

degrees of freedom of motion is as close as you can get in layman terms when describing dimensions, now if we want to talk of antimatter universes that a different matter.

Well String theory is a vague ambigious area science. Last time I heard this Ed Witten came along and 'merged' all the different theories into one theory called M-theory, which isn't so problematic. It only needs two pieces of evidence to prove it exists; Gravitons and Sparticles (which also proves Supersymettry) (when I say prove, I mean it has some evidence to bring the theory into the possible regions of the theorhetical spectrum). This theory was made about 10 years ago, so I'm not too sure if it's still 'the' String Theory, but I believe it would be because CERN and Fermilab are still racing to find Gravitons and Sparticles.

Well, I never said people were mistaken here, I'm just stating that people are getting their nomenclature a bit mixed up here. The Term Dimension is an ambigious term which can mean degrees of freedom (in Mathmatics) and alternate universes. I think some people wrote alternate dimension and you started talking about the 'other' definition, it's just a plain misunderstanding, which happens all the bloody time over forums

http://www.damtp.cam.ac.uk/user/gr/public/qg_ss.html

Good site here, I suggest you read it (or at least the part about dimensions), helped me understand the absolute basics  

I believe the thread was made to talk about the idea of an anti-matter universe, nothing about extra dimensions.

actually M theory makes it more so, original string theory introduct about 50 random constants. M theory raised this to around 100.

Basically M theory states all of the different string theories and SUSY theory are just different views of the same master theory, what this matter theory is dependents on the number of holes or manifolds a single point of space possess.

What Witten did not state is how many holes are there for our universe, what determines this factor or set the value of the other constants that M theory would depend on.

For the last 10 years scientist have conducted 1000's of experiments, search cloud chambers, and stared at distant Quasars to find a hint  that even one of these extra dimensions that string theory predict exist.. No evident in the least, on top of that it has failed to predict dark energy ( which Einstein did in General relativity) or account for several of the surprises that have sprung up in the field of particle physics...As many physicist have comment of late, we have made no major advance in the last 25 years since string theory has reared it eleghant yet ugly head..

As for your link, i believe i understand string and m theory just fine.. thanks anyway.

As for the antimatter universe, since we donot why antimatter is not plentiful in our own, and since there is no hint of other universes, it doubtful that another universe filled with antimatter exist, especially in the light that there is no place for it to exist if other dimensions donot. For multiuniverses to exist there would need to be a seperate larger spacial dimension to place them all in.
