What if WE are two-dimensional beings as well?


According to the theory of the holographic universe:

http://en.wikipedia.org/wiki/Holographic_Universe

"In a larger and more speculative sense, the theory suggests that the entire universe can be seen as a two-dimensional information structure "painted" on the cosmological horizon, such that the three dimensions we observe are only an effective description at macroscopic scales and at low energies. Cosmological holography has not been made mathematically precise, partly because the cosmological horizon has a finite area and grows with time."


Then there is the theory that our universe is just a thin sheet, suggested by mathematical physicist Neil Turok:

"Imagine two sheets on a washing line, and they’re very close together, very nearly parallel. Those are two-dimensional sheets; ours are three-dimensional. Think of it as two intimately intertwined objects which are nevertheless able to exert force on each other, a pull. The Big Bang is the touching of those two sheets. When they touch, they release that energy."





But if the theory about the holographic universe is correct, our three-dimesional sheet could actually be a two-dimensional sheet, which really does remind about the kind of world the inhabitants of Flatland are living in.

So perhaps is our three-dimensional world just an illusion? If so, what would we see if we were able to see behind the curtain? It could be an interesting idea to explore in a science fiction story of some kind.
