    M-Theory forsee the existence of 6-7 extra space dimensions to the current 4D (3spacial + 1time).

    They are forseen to be at Planck dimensions and rolled (Kaluza-klein hypathesis)....making 6D Calabi-Yau shapes....So they are no able to be perceived for us at our scale...

    I have some questions I don´t have clear:
    • Can 6D shapes be contained or harmonized by a 3D space ?
    • Those diferent Calabi-Yau shapes can be considered different 6D entities?
    • If there is other type of entities within this shapes...the will be also 6D entitíes?
    • There could be any type of connexion between different 6D shapes?...and through the 3D space?

    M-Theory also talk about the supersimetry ... and the similarity between r = 1/r.....then is it possible that could be other dimensions over Our Universe?
    • Is it posible that Our 4D Universe (3spacial + 1time) would be contained within a 5D shape (4spacial + 1time) ?
    • If there are several Universes like Our...out there (beyond the limmits of our universe)....they could be contained or harmonized by a 5D space ? ... or other nD?
    • There could be any type of connexion between those universes?...
    There is any maths speciality taht manage these topics?... Set Theory, manifolds,...Riemann...

    All that I understood at first sight...Its the reason why universes wont get packed in a point isnt it? Contraction turns into expansion...As I recall there was two inversions happening at the same time? But I agree from the start that it is likely (IF the universe has an outside environment) that it exists in a fivedimensional space. I never liked the idea that curvature could be only an internal affair of the line.
    Circles dont have their definition point (the center) within the line. Then: Im no matematician. Dunno if i really would like to be...theres more things I dont believe in without understanding the prooof.

    Please, have a look to the Brane Theory: Brane cosmology - Wikipedia, the free encyclopedia there is very nice proposal to be considered...

    "The central idea is that the visible, four-dimensional universe is restricted to a brane inside a higher-dimensional space, called the [U]"bulk"[/U]. If the additional 6 dimensions are compact (within a 6D Calabi-Yau space), then the observed universe contains the extra dimensions, and then no reference to the bulk is appropriate. In the bulk model, at least some of the extra dimensions are extensive (possibly infinite), and other branes may be moving through this bulk. Interactions with the bulk, and possibly with other branes, can influence our brane and thus introduce effects not seen in more standard cosmological models."

    So Our Universe (4D=3space+1time) is between the 6D (6space) Calabi-yau dimensions, and the higher dimensional space (5D= 4space+1time) "Bulk"
