Solid State Universe

So if one could prove that the Universe was a hypersphere, with the concept of Pi built directly into its intrinsic existence, the physical representation of the Universe would be less perfect than the math which can only describe it by approximation?
I call shenanigans on you, Sir.

The first proof of irrational numbers is usually attributed to Hippasus of Metapontum, a Pythagorean who produced a (most likely geometrical) proof of the irrationality of the square root of 2. The story goes that Hippasus discovered irrational numbers when trying to represent the square root of 2 as a fraction (proof below). However Pythagoras believed in the absoluteness of numbers, and could not accept the existence of irrational numbers. He could not disprove their existence through logic, but his beliefs would not accept the existence of irrational numbers and so, as legend had it, he had Hippasus drowned. Theaetetus worked with other quadratic irrationalities, but it wasn't until Eudoxus developed a theory of irrational ratios that Greek mathematicians accepted irrational numbers. Euclid's Elements Book 10 is dedicated to classification of irrational magnitudes.
My interest in this discussion is purely philisophical. There are fields of philosophy that describe math, physics and cosmology and it is the root of assumptions inherent in this field that I am addressing.
Math cannot predate observations that create the knowledge of formulation of these observations. Your complex number and hypersphere analogy involves extrapolation from previously understood formulations, which gives the flaw in your argument.
As for spacetime, as I said previously the entire concept of an expanding universe is that it's based on a metric expansion of points in spacetime, not the physical expansion of the universe into the space around it. If the Universe could be compressed into a single point by this logic, there would be no dimensional spacetime around that point for 'space' to exist within.
As for the Universe being irrational and the concept of singularities, I'll refer back to the question of two singularities orbiting each other in a deteriorating spiral. By mathematical logic, removing 'evaporation' from the equation, these two points in spacetime would recede into infinity as their orbital velocity around each other approaches the speed of light. Accurately measuring the spiral through pi would involve reiterations extending onwards into infinity. There is no other way for math to describe such a spiral.
I have never said that scientists consider themselves on the same playing field as God. But scientists who follow after do have a tendency to put their learned predecessors on pedestals, much like the followers of Pythagoras.
