How many dimensions are plausible?

[chesty]

Based on Superstring theory? Not silly string although it is anecdotal.

I am reading one book that postulates with some proof that before the big bang there were 10 unified dimensions. When the BB happened, as the Universe started to cool 4 unified into our universe and 6 into another.

Have at it!

 

[hardrock]

uummm. yes.

 

[gonelifting]

In!

 

[chesty]

out

i never understood that stuff, is each dimension a different yet same universe?

 

[chesty]

no...we live in the four dimensional universe, length, width, height, and time. I have no idea what a six-dimensional universe would be.

 

[hamstershaver]

then what was a 10 dimensional one?

 

[chesty]

beats me... it was our universe prior to the BB

 

[hamstershaver]

that was one hell of an answer

 

[chesty]

well I could write the tensor dynamical equations, but then I don't understand them anymore than probably most of us here.

on the other hand, I also figured that maybe the missing mass or "dark" matter in the Universe was this 6 dimensional universe. While we can't directly detect it, we can infer its existence by the effect it has on the observable Universe.
