IF the material universe was described by the various algorithms of maths within the confinement of the singularity, and the release (big bang) of this information was permitted with the creation of space by the dimensions, what if any shape of existing space would be discernible by an extrapolation how of these dimensions were expressed? If the dimensions were the first information expressed outside the singularity, it seems logical that they were expressed in a particular order of simpler to more complex. That order being: First the X axis, or the first appearance of a line of (theoretical) primordial energy with an intersection at the singularity, then the second being the addition of the Y axis, with the line becoming a 2D plane, then the addition of the Z axis, becoming the 3D inflation volume as proposed in theory. It is at this point that theoretical energy crosses the barrier between theoretical reality and extant reality with the final dimension in place. If this sequence of order of dimensionality "construction", or description is right, then the overall shape of the universe should have a remnant of the original single line, and/or the single plane in the CMB readings.

I suppose the original straight 1-D line, would get curved into a circle when the Universe went 2-D.

 

Then the circle would get multiplied into a sphere, or "circle of circles", when the Universe reached full 3-D.

 

So no trace would be left of the original line,

dekan, the line (1D)would go to a plane(2D) like a rectangle, then the rectangle would go cubical form(3D), expanding out at inflation speed (superliminal) then settled down to light speed rate expansion as the universe cooled.....and tegmark has claimed a line or "equator" in his CMB survey map ......edd
