2. I also hoped to elicit the uncanny powers of your probitive skills and analysis towards an explantion of how it is possible that the physical Universe as we understand it to be is as flat as a three-dimensional shape can possibly be as confirmed by the cosmology commmunity.

I am not sure we read the same thing into this: "as flas as a three-dimensional shape can possibly be". What do you suggest it means? Three dimensional space is three dimensional space, I don't know if you can talk about "degrees" of flatness.
The paper contains this paragraph:

Boomerang has measured the peak with unprecedented precision and gives confirmation of the primordial origin of the fluctuations. Moreover, the measured peak agrees precisely with the expectation for a flat universe. The location of the peak means that the density of matter is within 10% of the critical value. The universe must therefore be dominated by dark energy - the modern reincarnation of the cosmological constant.

Since the paper is now over two years old, we must take new evidence into consideration. Numerous papers have been published since then, and this summer there has been a lot of attention concerning the amount of not only dark matter but also "dark energy", which has been found (in theory, of course) to reconcile Einstein's relativity theory and the expansion rate of the Universe.
